Global bitcoin share
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms
How many cryptocurrencies are there in the world
at present, there are more than 1350 encrypted virtual currencies in circulation in the world. So far, according to the total valuation given by the market price, there are 23 virtual currencies with a valuation of more than US $1 billion, 97 with a value of more than US $100 million, and 573 with a market value of more than US $1 million. All in all, the total market value of virtual currency has exceeded US $5 trillion, of which bitcoin, the earliest invention, accounts for more than half. Players generally admit that bitcoin is not the most effective cryptocurrency, nor is it the most covert and anonymous. However, bitcoin is the first one to appear, so it is the most well-known and popular one
so the question is, does the world need more than 1350 cryptocurrencies
even the players of virtual currency will doubt this. No matter how strange the world is, there cannot be so many virtual currencies. In fact, there are so many new ICO virtual currencies emerging in recent years, which complement the "Crazy" performance of bitcoin in this year. Most of these 1300 kinds of virtual currencies can't be recognized by everyone. From the beginning of ICO, there will be many loopholes that no one will fill. When there is a major adjustment in the virtual currency market, many of them will disappear automatically, which means that no one will go to mine any more
this also leads to a problem. When some of the cryptocurrencies have problems, the entire instry chain and market of virtual currency may be involved like dominoes. Even the strongest bitcoin now will also be involved, because the cryptocurrency, in the final analysis, is supported by the "belief" of players
why is bitcoin worth more than other cryptocurrencies
at the time of writing this article, the total value of bitcoin is about US $270 billion, the total value of cash of bitcoin is about US $31.7 billion, and the market value of bitcoin gold is US $5.17 billion. Since bitcoin cash and bitcoin gold are separated from bitcoin, in a broad sense, they should be counted as a part of the total value of bitcoin (of course, you can't refute me technically, just for a rough explanation). Once we add up all the branches of bitcoin, we can calculate the market value of more than $310 billion. As a result, bitcoin accounts for about 60% of all cryptocurrencies in the market
as I have repeatedly said in recent days, bitcoin is not the most effective cryptocurrency, the most advanced, the most anonymous, or even the most stable cryptocurrency. So why is bitcoin so valuable compared with other virtual currencies
it's very simple, because bitcoin has a catalytic factor, that is, the Chicago Board of trade, as well as the commodity exchange, began to trade futures as a "commodity". Then, you will naturally think that since it has been recognized by the futures exchange, will it be further recognized by the US government in the next step. Other virtual currencies are still struggling
however, we have always stressed that since the day bitcoin was traded as a "commodity", its real monetary role, like gold, has been very weak in reality, but as one of the procts of gambling. This means that we all do bitcoin as a speculative activity, rather than a real use
judging from the current situation, bitcoin is no longer the only virtual currency that soars as soon as there is news of "official support". It is like iota, a virtual currency that focuses on the principle of the Internet of things. The news of cooperation with Microsoft came in the last two weeks, and it immediately rose to more than $300. Later, Microsoft came out and said that there was no such thing, and iota immediately fell back. It can be seen that in the future, as long as the virtual currency is recognized by some big company or organization, it will soar like bitcoin
