Is Bitcoin Really A Safe-Haven Asset? - Forbes
I bought my 1st Bitcoin, now what?
HELLO BIITCONNEEEECT! (if you know you know) I just bought my first bitcoin and I'm pretty happy with the outcome so far. I signed up for Binance and downloaded Exodus (cryptowallet). Ideally I'd like to now move on with my life. However, I've been told to send all my bitcoin into a wallet of my own, instead of leaving it in Binance's wallet. I'm not sure why, I'm assuming it's due to security concerns? Anyway, I'm curious as to how do I send my bitcoin from Binance to my wallet? Furthermore, what if my computer gets stolen or damaged? Can I still access my Exodus? I tried searching Google before I came to you guys, but all the info is too much for me and I'm too old to get into this stuff, I just wanted to invest a bit given the following news: "BANK OF ENGLAND IS SAID TO BE CONSIDERING A CONTROVERSIAL MOVE INTO NEGATIVE INTEREST RATES - THE TELEGRAPH" Many thanks, everyone.
In early October, the US Commodity Futures Trading Commission (CFTC) charged this crypto exchange with illegally operating an unregistered trading platform.

Ranking and October Winners and Losers
2019 Top Ten Ranking - 40% dropout rate After losing quite a bit of ground in the rankings in September, the 2019 Top Ten rebounded a bit in October. Only BSV finished down on the month, down two places (from #9 to #11) and dropping out of the Top Ten. The rest either held or climbed: EOS, Tron and Stellar each advanced one position each and Litecoin picked up four places and was able to rejoin the Top Ten. It’s good to have LTC back in the familiar confines of the Top Ten, as last month it found itself on the outside looking in, for the first time since the Experiments started back in January 2018. 40% of the crypotos that were in the Top Ten on January 1st, 2019 have dropped out: Tron, Stellar, BSV, and EOS have been replaced by BNB, DOT, ADA, and LINK. October Winners – Big PoppaBTC had a great month, finishing up +25%. Second place goes to LTC, up +17% in October, followed by BCH, up +14%. October Losers – The losses were moderate this month, but the L for October goes to BSV, which lost -7% and fell out of the Top Ten. EOS was second worst performing, down -5%. For overly competitive nerds, here is a tally of which coins have the most monthly wins and losses during the first 22 months of the 2019 Top Ten Experiment: 2019 Ws/Ls Because it's the default winner in down months, Tether is still far ahead in terms of monthly victories (7). That’s more than twice as much as second place BSV, BTC, and ETH. And although BSV is up 74% since January 2019, it dominates the monthly loss count: it has now finished last in nine out of twenty-two months (paying attention, swing traders?). And XRP is still the only crypto that has yet to notch a monthly win.
Overall update – BTC’s lead increases, XRP back to the basement, 2019 Top Ten pulls ahead of other Experiments.
BTC extended the lead it carved out last month over second place ETH in October. The top two are up +262% and +191% respectively, followed distantly by Litecoin, which is up +79% since January 2019. The initial $100 investment in BTC is currently worth $369. For the first time since April 2019, BSV has dropped out of the Top Ten. Twenty-two months into the 2019 Top Ten Index Fund Experiment, 70% of the 2019 Top Ten cryptos are either flat or in the green. After barely escaping the basement last month, XRP has once again sunk to the bottom of the pack, down -33% since January 2019. At +66%, the 2019 Top Ten Portfolio has pulled ahead of the 2020 Top Ten Portfolio’s +61% gain and both are far, far ahead of the 2018 group , which is down -74% (more on that below).
Total Market Cap for the entire cryptocurrency sector:
Total market cap since Jan 2019 is +215% Since January 2019, the total market cap for crypto is up +215%. The overall market gained about $50B in October, ending the month just over the psychologically important $400B mark. This is now the highest month-end level since the 2019 Top Ten Experiment began 22 months ago.
Overall return on investment since January 1st, 2019:
The 2019 Group gained $122 in October, so after the initial $1000 investment, the 2019 Top Ten Crypto Portfolio is worth $1,660. 2019 Top Ten Index Fund Experiment ROI For some context, here’s a look at the ROI over the life of the first 22 months of the 2019 Top Ten Index Fund experiment, month by month: 2019 Top Ten ROI summary Unlike the completely red table you’ll see in the 2018 Top Ten Experiment, the 2019 crypto table is almost all green. The first month was the lowest point (-9%), and the highest point (+114%) was May 2019. At +66%, the 2019 Top Ten Portfolio is now the best performing out of the three Experiments but not by much: the 2020 Top Ten Portfolio is up +61%. Speaking of the other Experiments, let’s take a look at how the 2019 Top Ten Index Fund Portfolio compare to the parallel projects:
Taking the three portfolios together, here’s the bottom bottom bottom line: After a $3000 investment in the 2018, 2019, and 2020 Top Ten Cryptocurrencies, my combined portfolios are worth $3,537 ($264+ $1,660 +$1,613). That’s up about +18% for the three combined portfolios, compared to +11% last month. Here’s a table to help visualize the progress of the combined portfolios: 2018, 2019, 2020 Top Tens combined ROI To sum up: +18% gain by dropping $1k once a year on whichever cryptos happened to be in the Top Ten on January 1st, 2018, 2019, and 2020. But what if I’d gone all in on only one Top Ten crypto for the past three years? While many have come and gone over the life of the experiment, only five cryptos have started in Top Ten for all three years: BTC, ETH, XRP, BCH, and LTC. Let’s take a look at those five: A tie: BTC catches up to ETH this month for leader of the Three Year Club Up until this month, Ethereum would have been your best bet. As of the end of October, it’s basically a tie between BTC and ETH. Both are up +121%, (although BTC is technically $21 ahead of ETH). On the other hand, if I had followed this world’s slowest dollar cost averaging approach with XRP, I’d be down -32%. With BCH I would have just about broken even. Alright, that’s crypto. How does crypto compare to the stock market?
Comparison to S&P 500:
I’m also tracking the S&P 500 as part of the experiments to have a comparison point with traditional markets. The S&P continued to fall from an all time high in the summer, and is now up +30% since January 2019. S&P since Jan 2019? +30% The initial $1k investment I put into crypto 22 months ago would be worth $1,300 had it been redirected to the S&P 500 in January 2019. +30% is not a bad return at all. But the 2019 Top Ten Portfolio is up more than double (+66)% over the same time period. That’s 2019. But what if I took the same world’s-slowest-dollar-cost-averaging $1,000-per-year-on-January-1st crypto approach with the S&P 500? It would yield the following:
$1000 investment in S&P 500 on January 1st, 2018 = $1220 today
$1000 investment in S&P 500 on January 1st, 2019 = $1300 today
$1000 investment in S&P 500 on January 1st, 2020 = $1010 today
Taken together, here’s the bottom bottom bottom line for a similar approach with the S&P: After three $1,000 investments into an S&P 500 index fund in January 2018, 2019, and 2020, my portfolio would be worth $3,530. That is up +17.6%since January 2018. Compared to a +17.9% gain of the combined Top Ten Crypto Experiment Portfolios. You can also compare against five individual coins (BTC, ETH, XRP, BCH, and LTC) by using the table above if you want. It’s small, but that tiny 0.3% difference in favor of crypto. That’s now seven monthly victories for the S&P vs. three monthly victories for crypto, all clustered in the second half of the year. Crypto re-takes the lead in October....barely
Thanks mainly to Bitcoin, October was a good month for crypto and a good month for the 2019 Top Ten Portfolio. As traditional markets have struggled over the last few months, crypto seems to be headed in the opposite direction. I’m looking forward to seeing if those trends hold in the last few months of a crazy year. Take care of each other out there, stay safe. Thanks for reading and for supporting the experiment. I hope you’ve found it helpful. I continue to be committed to seeing this process through and reporting along the way. Feel free to reach out with any questions and stay tuned for progress reports. Keep an eye out for the original 2018 Top Ten Crypto Index Fund Experiment and the 2020 Top Ten Experiment.

Help needed with possible bitcoin scam "in progress", can I get some money back?
Good day all, so, although I was relatively safe, I would like your advice and take on this: I just wasted 300USD into it, and I am not 100% sure it is a scam. I would like to warn people/ask for advice. A year or 2 back I matched a girl on tinder who came from HongKong and we became acquantainces on whatsapp: never met each other in real life, but talked off and on. Three months ago (I assume that's when she lost her number to someone else) she started talking about investing and getting some money out of it, which I initially didn't really care about, since I am happy with my index funds. She had a friend of an uncle who advised her. The weird part is that she still continued to send pictures of her doing stuff. After three months I decided: The worst part that can happen is me losing 100USD to the bitcoin market. She convinced me to open an account on Binance, bank-transfer money into it and then transfer to a MT5 trading platform. After I talked with the advisor, he said he would advice me on 3 deals to 'show his sincerity' and he would obtain his fee by the transfer fees. He adviced me twice to 'short-sell' at some point. I am currently at two trades and have made (in my opinion) a rediculous amount of money (80% gain) and I am now at like 540USD according to this platform. However, when I tried to withdraw 20USD money from the account on their site, it failed and some (czech?) websites indicated the website was a scam. After the weekend he will probably contact me for a 3th trade, where I assume I probably lose all my money. I would, ofcourse, like my money back: What are my options? - She knows my financial situation and that I have 30k inheritance coming my way (told her about the funeral a month back), can I try to bait them back? ;) - I am from Germany, can I go to the authorities or is it too early? - I notified Binance, but they can't do anything (obviously). Thanks in advance. It is really complicated and I wondered why I didn't lose the contact/money when I transferred it from binance already. Update: got their IP-Adress through some elaborate means, which is 22.214.171.124 Which is also reported to be scammy. If someone has a DDOS lying around, that would be nice :P. (Joking, not suggesting!). Hopefully this IP is not against rule #1
What is the best cryptocurrency to invest in right now?
What is the best cryptocurrency to invest in right now?
Traders worry every day about which cryptocurrency to invest in. The crypto market, however, is still difficult to predict. There is no simple answer as to which coins will win the race in 2020. The guarantee: Bitcoin Bitcoin will always be a good investment. Satoshi Nakamoto’s invention continues to lead in terms of market capitalization and trade volume. Almost every crypto exchange can trade Bitcoin and it is the cryptocurrency that is used the most. If you can or just want to invest in a single cryptocurrency, Bitcoin is always a good choice. The first true peer-to-peer currency is still the number 1 cryptocurrencies. So far, there is no indication that Bitcoin will be thrown from the throne in the foreseeable future. The next Bitcoin Halving will also take place in 2020. This means that fewer coins are distributed during mining. The available amount grows more slowly, so that every single coin becomes more valuable as soon as the demand increases. Many investors expect price increases after halving. It is not guaranteed that Bitcoin will experience the biggest growth in 2020. But it’s the most stable cryptocurrency to invest so far. Advantages: – Strongest market dominance, largest trading volume – The most widely used cryptocurrency worldwide – Secure facility Bitcoin alternatives Bitcoin clones could also be a safe investment: cryptocurrencies such as Bitcoin Cash (BCH), Bitcoin Gold (BTG), Litecoin (LTC) or Bitcoin SV (BSV). These cryptocurrencies are mostly faster and more technically advanced than Bitcoin, but will not be able to break its market dominance in the foreseeable future. They have the same purpose: digital means of payment for the Internet. Your prices often move parallel to the Bitcoin price, but can also rise or fall with a time delay. Some of them have the potential to grow faster than their template, but it is not guaranteed. – Good alternative to diversification – Potential for big price gains Binance Coin (BNB) The Binance Coin (BNB) is the cryptocurrency of the largest exchange in the world: Binance. The Exchange has expanded considerably in recent years and plans to continue doing so in 2020. An investment in the Binance Coin is equivalent to an investment in the Exchange. The Binance Coin can be used to trade on the cryptocurrency exchange. If you buy cryptocurrencies with her, you get discounts on your purchases. Binance coins therefore have a benefit for every trader. Binance will soon start a decentralized exchange called Binance DEX, on which in turn the in-house cryptocurrency can be used as a means of payment. That makes the Binance Coin extremely liquid. Shortly after the start of the cryptocurrency, it was able to get a permanent place in the top 10 largest cryptocurrencies on CoinMarketCap. In 2019, the BNB price tripled. – Extremely liquid cryptocurrency – Currency on the largest exchange: Binance – Could already gain good prices Tron (TRX) Tron is a blockchain platform from Justin Sun, an important figure in the crypto scene. An independent ecosystem for the entertainment industry is to be created on the platform. Every user should be able to upload their own videos, pictures, music, texts etc. without being dependent on companies like YouTube. Basically, it’s a smart contract platform, similar to Ethereum (which is also a good investment). Users can upload data, make it available to other users and write their own smart contracts. Tron now attracts a large number of investors. There is a lot of potential in the project. In 2017, Tron’s price rose from EUR 0.0018 to EUR 0.045. In 2018 and 2019, the cryptocurrency gained more and more ground in the crypto world and is now among the top 15 in terms of market capitalization.

What is the best way of selling a trading algorithm?
I created a trading algorithm which I want to sell. Its not scam, which usually people say when you want to sell it instead of keep it to urself. I dont really understand why except of being sceptical, correct me if im wrong. I want to know what kind of money making strategies are the best for selling my trading algorithm.
Payments for running my algorithm
Server 1, for my website.
Server 2, for my algorithm. (for security and performance its better to keeps these 2 seperate.)
Maybe some other payments I dont know yet that I have to pay for.
These payments are usually monthly or yearly payments.
Earnings that could be invested into the payments above
A part time job with an average salary of around 1k a month.
Me investing money into my own bot. I could withdraw a specific percentage after each profit trade. Balanced just right so I still raise in money thats inside my bot and do not get just 5 cents out of the withdraw.
These are earnings I could use to invest when im at the startup period. Since I would probably not earn enough money in this period with as good as no users at all.
Money earned from people that invested into my bot (algorithm).
This is the earning I want to use when im **not** in the **startup period**.
These are the strategies I am thinking of:
Starting is free, trades made by my bot (algorithm) have trading fee's from, for example, binance. And withdraw costs are 10% where, for example, 1% goes to binance and 9% to me. Pros:
New users might think its pretty cheap, they would lose nothing then already free earned money. the algoritm made $50 into $500 for them and they only lose 10% of it. Which would be $450 left with a $50 loss from that $500. This could result into more users, meaning more money invested in my bot.
If a user puts $1000 into my bot and keeps it running for 10 years with an average profit of 100% per year they would end up with 1 million. If users actually keep there money for this long without any withdraw I would basicly not earn any money from them till the last 10th year. If I do not have enough users that do withdraw in time it could result in being bankrupt...
I am not so sure if I can even make this strategy possible. Since the accounts are from an exchange like Binance I dont know if I can make sure an user can only withdraw at my website, so I can make sure I receive that 10% (-1% to binance, so 9%). If an user could login into there account and withdraw on the binance website I ofcourse can't receive that 10% so easily.
Inactive users. Users who lost there account or are not using it for any other reason. I would never receive any money from these type of users.
My opinion I would like to use this strat mostly because of my first pros. I told some real life people what I am creating and they where all saying that if it was only 10% they would for sure do it. These where people that never traded before and some of them I even had to explain what bitcoin was... This is ofcourse not my target audience but I would totally not mind if they would invest in me. Everyone was new to trading at some point and maybe I can be the trigger for them to start getting into it (or better said, getting into me :D ).
Starting is free, each trade made by my algorithm, buy or sell, will cost the user, for example, 0.5% of the amount. Where the withdraw costs are 0, exept for the costs that binance asks. Pros
I would earn **ALOT** more money the early states and would be able to pay off the servers or even upgrade them way fasteearlyer. This removes the risk of getting bankrupt at some point by not earning enough.
I would 100% sure be able to receive money from users, there would be no way (as far as I know) that users could bypass the costs. Which in strategy #1 may be possible.
Inactive users would not matter.
As good as all other websites that sell there algorithm's have this way of selling. I Belive being unique can work in case of getting extra users. They might think im different then these "scammers" if I use strategy #1.
Users might feel like they lose alot of money if they would start doing alot of calculations. And in the long term, they will ofcourse lose more money. Which is good for me but bad for them. This could result into losing users or getting less "new/starting" users.
My opinion This is definitly a secure/safe option. Especially in the early states. Maybe I could use this in the early states and use strategy #1 after the startup period (for only new users). But this could make everything very complicated.
Starting will cost, for example, $500. Trading fee's are free, exept for the one's from binance. And the same for withdrawing. Pros
I would for sure earn from each user and will be able to pay off my server's costs. But only if im actually popular.
New users would not buy or try my algorithm because it might be to expensive.
New users would not buy or try my algorithm because they could think its fake and do not want to take the risk.
People who are not experienced in trading or in investing would probably never start using my algorithm. Since I told some of those kind of people about this project I know this is true.
I would only earn once and only a set amount which would not make me really that rich... :D
My opinion It has more cons then pros which in my opinion means this is just a bad strategy.
What I want
I would like to know what u guys think is the best strategy and especially why. I would like it if someone has actually some tested results in what people would probably like the most and what would "sell" the best. If someone knows a 4th strategy or even more then I would like to know. But only the best strategy I would use and which one that is is what I want to know. NOTE! These pros and cons are NOT directly some actual facts or have never been seriously TESTED by me so if one of these are actually wrong, im sorry.
$1,000 invested in Top 10 Cryptos of 2019 now worth $1,260 (UP +26%)
EXPERIMENT - Tracking Top 10 Cryptos of 2019 - Month Eighteen - UP +26% See the full blog post with all the tableshere. tl;dr - Tether (as it's designed to do) holds its ground, all others finish the month in negative territory. Tron finishes June in second place, down -2%. BSV loses nearly 25% of value in June. Overall, since January 2019, BTC in lead, ETH takes over second place, XRP still worst performing. The 2019 Top 10 is up +26% almost equal to the the gains of the S&P 500 over the same time period (+24%).
According to a June article citing unnamed sources, which two FinTech companies are planning to allow their users to buy and sell crypto directly?
A) Paypal and Venmo B) Square and Cashapp C) Robinhood and Revolut D) Sofi and Coinbase Scroll down for the answer.
Ranking and June Winners and Losers
XRP and Stellar slipped one place each in the rankings in June, now at #4 and #14 respectively. EOS fell two spots to #11 and joins Stellar and Tron as the only three cryptos to have dropped out of the 2019 Top Ten since January 1st, 2019. They have been replaced by Binance Coin, Cardano, and newcomer CRO. Tether was the only crypto to move up in rank in June. Not a good sign when Tether is the only crypto to move up. Not a good sign when Tether enters the Top 3. June Winners – Tether. Second comes Tron, which basically held its ground at -2%. June Losers – BSV lost -23% of its value in June making it the worst performing of the 2019 Top Ten portfolio. EOS had a rough month as well, down -17%, dropping two spots in the rankings, and falling out of the Top Ten. If you’re keeping score, here is tally of which coins have the most monthly wins and loses during the first 18 months of the 2019 Top Ten Experiment: Tether is still in the lead with six monthly victories followed by BSV in second place with three. BSV also holds the most monthly losses, finishing last in seven out of eighteen months. The only crypto not to win a month so far? XRP. (In fairness, XRP has also not lost any month yet).
Overall update – BTC in lead, ETH takes over second place, XRP still worst performing
BTC is out front for the second straight month and ETH has taken over second place from BSV. Ahead until April, BSV has simply not keep up with the pack over the last two months. Bitcoin is up +144% since January 2019. The initial $100 investment in BTC is currently worth $249. Eighteen months in, 50% of the 2019 Top Ten cryptos are in the green since the beginning of the experiment. The other five cryptos are either flat or in negative territory, including last place XRP (down -50% since January 2019).
Total Market Cap for the entire cryptocurrency sector:
The crypto market as a whole is down about $20B in June, but still up +106% since January 2019.
BitDom finally wobbled in June, but not by much – it’s been in a very familiar zone for months now, indicating a lack of excitement (or at least a low risk tolerance) for altcoins. Taking a wider view, the Bitcoin Dominance range since the beginning of the experiment in January 2019 has ranged between 50%-70%.
Overall return on investment since January 1st, 2019:
The 2019 Top Ten Portfolio lost almost $175 in June. After the initial $1000 investment, the 2019 group of Top Ten cryptos is worth $1,259. That’s up about +26%. Here’s a look at the ROI over the life of the first 18 months of the 2019 Top Ten Index Fund experiment, month by month: 18 months of ROI, mostly green Unlike the completely red table you’ll see in the 2018 Top Ten Experiment, the 2019 crypto table is almost all green. The first month was the lowest point (-9%), and the highest point (+114%) was May 2019. How does the 2019 Top Ten Index Fund Portfolio compare to the parallel projects?
Taking the three portfolios together, here’s the bottom bottom bottom line: After a $3000 investment in the 2018, 2019, and 2020 Top Ten Cryptocurrencies, the combined portfolios are worth $2,710. That’s down about -10% for the three combined portfolios. Last month that figure was +4%. Better than a few months ago (aka the zombie apocalypse) where it was down -24%, but not yet back at January (+13%) or February (+6%) levels. Here’s a new table to help visualize the progress of the combined portfolios: ROI of all three combined portfolios - not exactly inspiring How do crypto returns compare to traditional markets?
Comparison to S&P 500:
Good thing I’m tracking the S&P 500 as part of my experiment to have a comparison point with other popular investments options. Even with unemployment, protests, and COVID, the US market continued to rebound in June. It’s now up +24% in the last 18 months. The initial $1k investment I put into crypto would be worth $1,240 had it been redirected to the S&P 500 in January 2019. As a reminder (or just scroll up) the 2019 Top Ten portfolio is returning +26% over last 18 months, just about equal to the return of the S&P 500 over the same time period. Just last month the ROI of the 2019 Top Ten crypto portfolio was nearly double the S&P 500 since January 1st, 2019. But what if I took the same world’s-slowest-dollar-cost-averaging/$1,000-per-year-in-January approach with the S&P 500? It would yield the following:
$1000 investment in S&P 500 on January 1st, 2018: +$170
$1000 investment in S&P 500 on January 1st, 2019: +$240
$1000 investment in S&P 500 on January 1st, 2020: -$40
Taken together, here’s the bottom bottom bottom line for a similar approach with the S&P: After three $1,000 investments into an S&P 500 index fund in January 2018, 2019, and 2020, my portfolio would be worth $3,370. That $3,370 is up over+12%since January 2018, compared to the $2,710 value (-10%) of the combined Top Ten Crypto Experiment Portfolios. Here’s another new table that compares the ROI of the combined crypto portfolios to a hypothetical similar approach with the S&P 500: We see in June the largest difference in favor of the S&P since the beginning of 2020: a 22% gap. Compare that February, when there was only a 1% difference in ROI.
Since January 2019, the crypto market as a whole has gained +106% compared to the 2019 Top Ten Crypto Portfolio which has gained +26%. That’s an 80% gap. At this point in the 2019 Experiment, an investor would have done much better picking different cryptos or investing in the entire market instead of focusing only on the 2019 Top Ten. Over the course of the first 18 months of tracking the 2019 Top Ten, there have been instances this was a winning strategy, but the cases have been few and far between. The 2018 Top Ten portfolio, on the other hand, has never outperformed the overall market, at least not in the first thirty months of that Experiment. And for the most recent 2020 Top Ten group? The opposite had been true: the 2020 Top Ten had easily outperformed the overall market 100% of the time…up until the last two months.
As the world continues to battle COVID, traditional markets seem to be recovering. Will crypto make a significant move in the second half of 2020? Final word: Stay safe and take care of each other. Thanks for reading and for supporting the experiment. I hope you’ve found it helpful. I continue to be committed to seeing this process through and reporting along the way. Feel free to reach out with any questions and stay tuned for progress reports. Keep an eye out for the original 2018 Top Ten Crypto Index Fund Experiment and the recently launched 2020 Top Ten Experiment.
And the Answer is…
A) Paypal and Venmo According to a Coindesk report in June, three sources familiar with the matter say that Paypal and Paypal-owned Venmo are planning to allow their users to buy and sell crypto. Paypal has declined to comment.
11-05 20:58 - 'Is Bitcoin Safe and Legal?' (self.Bitcoin) by /u/koinalio removed from /r/Bitcoin within 2-12min
''' Buying, selling, or trading bitcoin is a private transaction in every part of the world. It is a lawful activity in most western and advanced countries, including the US, Canada, and the U.K. Some large economies have restrictions on Bitcoin, including China (ownership discouraged although not a criminal violation) and India ( banks banned from engaging in Bitcoin). Governments everywhere have concerns with the anonymous movement of funds; they wish to prevent the use of money for illegal purposes. Koinal understands the importance of anti-corruption laws and maintains legal standards for all sales and purchases. The best advice is to consult the laws of the country where one lives and intends to do business with Bitcoin. Koinal operates within the bounds of all applicable laws and meets legal requirements for transactions in every state in which it does business.
Is Bitcoin Safe?
The safety of Bitcoin also has some variables. Like all cryptocurrencies, there is no physical note or document. Owners must safely keep their digital currency and access codes because if lost or misused, there may be no recourse. An elaborate security system surrounds Bitcoin. The digital currency exists in a blockchain that cannot be altered by any government or central authority. Every Bitcoin transaction is transparent and watched by a global network. Unlike some other types of transactions, once the Bitcoin moves, there is no reversal mechanism. When you sell or buy, the transfer cannot be undone or canceled. Bitcoin is the oldest of the major currencies that include Ethereum, Lite, and Ripple. Bitcoin, by far, has the highest value, and many investors prefer Bitcoin for investment potential. Bitcoin is among the small group of cryptocurrencies that bring high levels of interest from mainstream financial companies and banks. Relative to other cryptocurrencies, Bitcoin enjoys a high level of interest. It is the most well-known cryptocurrency.
People can buy cryptocurrencies in many ways. The blockchain ledgers keep track of Bitcoin’s existence and ownership, and owners can transfer it on a peer-to-peer basis. Peer to peer transactions does not require any action by a government, bank, or any central authority. A safer and more widely used method is to perform transactions on Bitcoin exchanges. [Koinal works with Binance]1 and other leading currency exchanges. Koinal provides a simple and effective way to purchase Bitcoin using regular bank credit cards and debit cards.
Taxes and Virtual Currency
Bitcoin transactions can result in taxation when used to pay for goods, services, and wages. While it is not a recognized form of currency under U.S. tax law, it does have value. In some instances, the tax code assesses Bitcoin by its fair market value at the time of purchase. The U.S. government’s Internal Revenue Service has noticed Bitcoin and digital currency. It issued an advisory in 2014 and a new item on the tax return for 2020. The IRS named Bitcoin as one of many virtual currencies. The IRS advises that Bitcoin may represent income under tax laws and maybe a taxable asset when held as property. When treated as property under a national tax code, Bitcoin may get treated like other assets that grow in value, such as the U.S. capital gains tax. Investors, buyers, and sellers should consult legal and tax advisors for advice on their situations. At Koinal, we do not offer tax advice. We simply point out that each investor must examine the tax implications of Bitcoin or other virtual currency transactions.
Keeping Within the Law and Regulations
Koinal takes all required steps to keep its transactions within the bounds of national laws and regulations. Koinal requires identification and personal information needed to comply with anti-corruption and know-your-customer rules(KYC).

Best places to trade your Ripple/XRP (longer read)
In the past when you heard the word ‘cryptocurrency’, the first thing that came to everyone’s minds was Bitcoin. To some, this is still the case; they believe that Bitcoin is the cryptocurrency and the vice versa to also be true. Of course, the statement is correct in one way; Bitcoin is a cryptocurrency, but cryptocurrency is not made up of only Bitcoin but a host of other currencies. One of these currencies is Ripple. When it comes to the top five cryptocurrencies with the highest capitalization, Ripple needs no introduction as it has managed to secure a position of being the third most traded cryptocurrency around the world. Perhaps this is due to the fact that Ripple is the only cryptocurrency with a backing from traditional legacy financial institutions. In addition, the coin has been integrated into the operation of thousands of small businesses around the world. At this juncture, it is only fair that you learn how to be a part of this great innovation. Thankfully, that is what this guide is all about, showing you some of the best trading platforms for Ripple. There are numerous exchanges that offer decent exchange rates and well-matched trading pairs, but I’ll only narrow down to some of our best picks to help you get started fast.
What is Ripple (XRP)?
Ripple is a cryptocurrency, a currency exchange, a real-time gross settlement payment system, and a remittance network powered by Ripple. As I mentioned before, this is the third most capitalized cryptocurrency asset after Bitcoin and Ethereum. XRP allows enterprises such as banks and other financial service providers to offer their clients a reliable option to source for liquidity for cross-border currency transactions. Ripple is a distributed, open-source platform that seeks to capitalize on the weaknesses of the conventional money payment systems such as credit and debit cards, PayPal, bank transfers, among others. According to Ripple, these payment systems expose users to a lot of transaction delays and restrict the fluidity of currencies. The platform aims at replacing traditional payment systems through offering a faster, safer, and more convenient alternative for making payments. Both the platform’s exchange and tokens are called Ripple, and their mantra states one frictionless experience to send money globally.
Where Can I Trade XRP?
Most exchanges that trade Ripple are limited to crypto-to-crypto transactions. This means that you can only trade Ripple with another cryptocurrency and not fiat currencies such as the euro or the dollar. You’ll need to acquire the currency you wish to trade with XRP on a platform that accepts fiat, and once that happens, you can proceed to trade the two currencies. There are several great platforms that offer XRP trading; below are just a few:
Buying XRP on Binance
Buying XRP on Bittrex
Just like on Binance, you’ll need to create an account on Bittrex to get started. The process is pretty much straightforward, only requiring you to sign up using your email address and password. Once you’re done signing up, click on the wallet tab. You will be taken to a page where you can view all the deposit addresses of the cryptocurrencies on the Bittrex platform. You can then choose the currency to use to purchase XRP, after which, you will be required to type in the code of the currency you will be using to purchase Ripple. If you’re using Ethereum, you can type in the search bar “ETH” and then click on the green arrow to reveal the deposit address. In case you will be sending the funds from a different exchange, you’ll need to paste the address to that platform. Next, you’ll need to send funds to your Bittrex account. Bittrex permits payments using both fiat and cryptocurrencies. So, depending on what you will be using, send money to your online wallet and proceed to trade it with Ripple.
Buying XRP on Changelly
Changelly is another Ripple exchange that requires you to use either Bitcoin or Ethereum to acquire XRP. The exchange doesn’t have an inbuilt wallet, so you’ll need to store your funds on a separate hardware or software wallet. You can pretty much use any type of wallet, but the most secure ones are the hardware ones as they store your coins in an offline cold storage area. Ripple prefers not to have many unutilized accounts being set up on its platform; this is why you’ll need to have a minimum of 20 XRP in your account for you to get started. However, if your first transaction will be more than 20 XRP, then you’re all set. Once you have a wallet ready for your Ripple, head to the Changelly site and click on “input currency”. Here, you will be able to enter the currency you wish to trade for Ripple. You can basically pick and use any coin listed on the site, but it is highly recommended that you use either Bitcoin or Ethereum due to their high liquidity. The output section will have Ripple, which is the currency you wish to receive. The next step will require you to key in your XRP address, which is your Ripple address and the destination tag, which is a description of the transaction. You can now proceed to trade your chosen coins for Ripple. The transaction shouldn’t take long, and you will be able to receive the coins in your Ripple wallet.
Cryptmixer is a platform that assists users to swap XRP with 5 other assets freely. The interface lets users convert assets directly from one’s wallet, without having to create an account or register. Besides, the service helps to compare different providers and find a suitable deal for handling Ripple transactions securely, rapidly, and at the best rate. The process of using Cryptmixer is quite simple:
Go to the main page, choose the currency you’d like to swap, and enter the amount.
Choose XRP to receive.
Review the amount to see how much you will receive. Cryptmixer will automatically find the best rates for your trade.
Then, enter the wallet address that you wish to use.
Send in the deposit to the generated wallet address and wait for the transaction to be processed.
What makes Cryptmixer a great fit is that it provides a very simple layout and quick process so it’s not chore when you trade your crypto. The support line also takes on the job of solving the cases by cooperating with users with top priority. To learn more on how to exchange XRP at the best rate check https://cryptmixer.com
Buying XRP on Coinmama
Coinmama is a cryptocurrency exchange that has been around for quite a while now. The Coinmama team has been adding more coins on their platform over time to be able to provide its users with a wider variety of trading pairs. More recently, the platform included Ripple on its platform. However, Coinmama does not allow US-based users to purchase Ripple due to some stringent laws and regulations surrounding the coin. But for non-US users, you can proceed to create your account on the platform and locate Ripple among the listed assets. Once you’ve created your account, navigate your way to the area with the list of assets. Select one of the provided packages and proceed. You’re required to have a crypto wallet prior to making any purchase on the platform, so be sure to have a valid wallet address before completing the purchase. Once that’s done, purchase your Ripple coins and they will be delivered to your wallet.
Storing Your Ripple Coins
Online storages are never safe for cryptocurrency assets. Individuals have woken up to all sort of horrific sceneries on their accounts that left them bankrupt with no one to turn to. One of the most important concepts you need to grasp about online businesses is the security of your transactions. Cryptocurrency burglars are everywhere and are getting smarter by the day; this means that traditional ways of guaranteeing the security of your online assets are no longer effective. Most exchanges have top-notch security standards, but the safety of your cryptos begins with you. A great way of ensuring that your funds are secure is by getting an offline storage device for your coins. I’ve seen great reviews on two hardware wallets that I highly recommend; these are the Ledger Nano S and Trezor wallets. After getting the wallet of your choice, keep your personal data such as passwords and secret words private; this will ensure that no one else gains access to your wallet even if you misplace it. Writing your password or PIN on open places or somewhere in your phone might not be a good idea; yes, it may be convenient for you, but it will be for the burglar too.
What method of purchasing XRP is considered to be the best?
The most secure and common way of acquiring Ripple is through buying Ethereum or Bitcoin from Coinbase or Coinmama, then transferring the same to Cryptmixer to use to exchange with Ripple. This is because Ripple is currently not available for purchase by using fiat currencies.
What is the best trading platform for Ripple?
Ripple is available on a decent number of exchanges including Binance, Coinmama, Coinbase, Bittrex, Cryptmixer, and more. However, among the stated ones, I have found Cryptmixer to be more secure and easier to use while it also offers the best trading rates and fees.
The Bottom Line
As we conclude, you now have some of the best choices when it comes to the exchange to acquire Ripple coins. After buying your XRP coins, store them offline on a secure device due to the risk of being faced by threats such as hacking or system failures. If you’re serious about making cryptocurrency your investment vehicle in the long run, consider investing in a more lasting security solution such as a hardware storage device. You may not get them for a few pennies, but trust me when I say they are worth every last dime you spend on them.
Here is how to play the altcoin game - for newbies & champs
I have been here for many previous altcoin seasons (2013,2017 etc) and wanted to share knowedle. It's a LOOONG article. The evaluation of altcoins (i.e not Bitcoin) is one of the most difficult and profitable exercises. Here I will outline my methodology and thinking but we have to take some things as a given. The first is that the whole market is going up or down with forces that we can't predict or control. Bitcoin is correlated with economic environments, money supply increases, safe havens such as Gold, hype and country regulations. This is an impossible mix to analyze and almost everyone fails at it. That's why you see people valuing Bitcoin from $100 to $500k frequently. Although I am bullish on the prospects of Bitcoin and decentralization and smart contract platforms, this is not the game I will be describing. I am talking about a game where you try to maximize your BTC holdings by investing in altcoins. We win this game even if we are at a loss in fiat currency value. To put it another way:
If you are not bullish in general on cryptocurrencies you have no place in investing or trading cryptocurrencies since it's always a losing proposition to trade in bubbles, a scientifically proven fact. If on the other hand you are then your goal is to grow your portfolio more than you would if holding BTC/ETH for example.
Bitcoin is the big boy
How the market works is not easily identifiable if you haven't graduated from the 2017 crypto university. When there is a bull market everything seems amazingly profitable and things keep going up outgrowing Bitcoin by orders of magnitude and you are a genius. The problem with this is that it only works while Bitcoin is going up a little bit or trades sideways. When it decides to move big then altcoins lose value both on the way up and on the way down. The second part is obvious and proven since all altcoins from 2017 are at a fraction of their BTC value (usually in the range of 80% or more down). Also, when BTC is making a big move upwards everyone exits altcoins to ride the wave. It is possible that the altcoin market behaves as an inversed leveraged ETF with leakage where in a certain period while Bitcoin starts at 10k and ends at 10k for example, altcoins have lost a lot of value because of the above things happening.
We are doing it anyway champ!
OK so we understand the risks and just wanna gambol with our money right? I get it. Why do that? Because finding the ideal scenario and period can be extremely profitable. In 2017 several altcoins went up 40x more than BTC. But again, if you don't chose wisely many of them have gone back to zero (the author has first hand experience in this!), they have been delisted and nobody remembers them. The actual mentality to have is very important and resembles poker and other speculative games: A certain altcoin can go up in value indefinitely but can only lose it's starting investment. Think about it. You either lose 1 metric or gain many many more. Now that sounds amazing but firstly as we said we have the goal to outperform our benchmark (BTC) and secondly that going up in value a lot means that the probability is quite low. There is this notion of Expected Value (EV) that poker players apply in these kind of situations and it goes like that. If you think that a certain coin has a probability let's say 10% to go up 10X and 90% probability it goes to zero it's an even bet. If you think that probability is 11% then it's a good bet, a profitable bet and you should take it. You get the point right? It's not that it can only go 10X or 0X, there is a whole range of probability outcomes that are too mathematical to explain here and it doesn't help so much because nobody can do such analysis with altcoins. See below on how we can approximate it.
How to evaluate altcoins
A range of different things to take into account outlined below will form our decision making. Not a single one of them should dictate 100% of our strategy.
It's all about market cap. Repeat after me. The price of a coin doesn't mean anything. Say it 10 times until you believe it. I can't remember how many times I had conversations with people that were comparing coins using their coin price instead of their market cap. To make this easy to get.
If I decide because the sky is blue to make my coin supply 100 Trillion FoolCoins with a price of $0.001 and there is another WiseCoin with a supply of 100 Million and price of $1 then FoolCoins are more expensive. - Alex Fin's Cap Law
This is done usually in the stock world and it means that each company has some fundamental value that includes it's assets, customers, growth prospects, sector prospects and leadership competence but mostly centered in financial measures such as P/E ratios etc. Valuation is a proper economic discipline by itself taught in universities. OK, now throw everything out of the window!. This kind of analysis is impossible in vague concepts and innovations that are currently cryptocurrencies. Ethereum was frequently priced at the fictional price of gas when all financial systems on earth run on the platform after decades (a bit of exaggeration here). No project is currently profitable enough to justify a valuation multiple that is usually equal to P/E in the thousands or more. As such we need to take other things into account. What I do is included in the list below:
Check Github. You need to make sure there is active development for the platform and it's a very bad sign if the project is either keeping the code closed source or even worse there is simply no development. No projects are "complete".
Check Website. If the website is written in bad English the Chinese google translate type it means that they are not serious enough to produce an unbreakable decentralized project. If you can't write English you can't change the world, period. That's a deal breaker.
Check Team's Linkedin. Numerous projects have either fake Linkedin accounts or the team is comprised mainly by unexperienced employees that are even shown to be working in other companies currently.
Check backers. Projects that have Binance, Coinbase or Silicon Valley VC funds backing them are way more legit but way more overpriced too!
One of my favorite ways to value altcoins that is based on the same principle in the stock market is to look at peers and decide what is the maximum cap it can grow to. As an example you take a second layer Ethereum solution that has an ICO and you want to decide if you will enter or not. You can take a look at other coins that are in the same business and compare their market caps. Thinking that your coin will outperform by a lot the top coins currently is overly optimistic so I usually take a lower valuation as a target price. If the initial offering is directly implying a valuation that is more than that then there is no room to grow according to my analysis and I skip it. Many times this has proven me wrong because it's a game theory problem where if many people think irrationally in a market it becomes a self-fulfilling prophecy. But since there is opportunity cost involved, in the long run, getting in initial offerings that have a lot of room to grow will pay off as a strategy.
In 2017 the sexiest sector was platforms and then coins including privacy ones. Platforms are obviously still a highly rated sector because everything is being built on them, but privacy is not as hot as it used to be. In 2018 DEXes were all they hype but still people are massively using centralized exchanges. In 2020 Defi is the hottest sector and it includes platforms, oracles and Defi projects. What I am saying is that a project gets extra points if it's a Defi one in 2020 and minus points if it's a payment system that will conquer the world as it was in 2017 because that's old news. This is closely related to the next section.
Needless to say that the crypto market is a worse FOMO type of inexperienced trigger happy yolo investors , much worse than the Robinhood crowd that drove a bankrupt company's stock 1200% after they declared bankruptcy. The result is that there are numerous projects that are basically either vaporware or just so overhyped that their valuation has no connection to reality. Should we avoid those kind of projects? No and I will explain why. There are many very good technically projects that had zero hype potential due to incompetent marketing departments that made them tank. An example (without shilling because I sold out a while back) is Quantum Resistant Ledger. This project has amazing quantum resistant blockchain, the only one running now, has a platform that people can build tokens and messaging systems and other magnificent stuff. Just check how they fared up to now and you will get the point. A project *needs* to have a hype factor because you cannot judge it as normal stocks that you can do value investing like Warren Buffet does where a company will inevitable post sales and profitability numbers and investors will get dividends. Actually the last sentence is the most important: No dividends. Even projects that give you tokens or coins as dividends are not real dividends because if the coin tanks the value of the dividend tanks. This is NOT the case with company stocks where you get dollars even if the company stock tanks. All that being said, I would advice against betting on projects that have a lot of hype but little substance (but that should be obvious!).
How to construct your portfolio
My strategy and philosophy in investing is that risk should be proportional to investment capital. That means that if you are investing 100K in the crypto market your portfolio should be very different than someone investing 1K because 10% annual gains are nothing in the latter while they are very significant in the former. Starting from this principle each individual needs to construct a portfolio according to how much risk he wants to take. I will emphasize two important concepts that play well with what I said. In the first instance of a big portfolio you should concentrate on this mantra: "Diversification is the only free meal in finance". In the case of a small portfolio then this mantra is more important: "Concentrate to create wealth, diversify to maintain wealth". Usually in a big portfolio you would want to hold some big coins such as BTC and ETH to weather the ups and downs explained in previous paragraphs while generating profits and keep progressively smaller parts of your portfolio for riskier investments. Maybe 50% of this portfolio could be big caps and 10% very risky initial offerings. Adapting risk progressively to smaller portfolios makes sense but I think it would be irrational to keep more than 30% of a portfolio no matter what tied to one coin due to the very high risk of bankruptcy.
The altseason is supposedly coming every 3 months. Truth is that nobody can predict it but altcoins can be profitable no matter what. Forget about maximalists who are stuck in their dogmas. Altcoins deliver different value propositions and it makes sense because we are very far from a situation where some project offers everything like Amazon and we wouldn't even want that in the first place since we are talking about decentralization and not a winner takes all and becomes a monster kind of scenario! Some last minute advice:
Stay out of paid telegram/discord pump groups. They are deadly for your wallet.
Avoid jumping on overhyped coins that have pumped massively during the last days without any very important news.
Don't keep coins in obscure exchanges for too long or you will get burned with certainty.
Stop thinking that your coin will 1000x and overtake Bitcoin!

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
