How much bitcoin is there in China
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
Let's start with a simple conclusion: a year ago, the data showed that there were about 500000 BTC
two American brothers, Cameron winkleworth and Taylor winkleworth, claiming that they owned 1% of bitcoin [1] 1% of the world's bitcoin? At present, the total amount of bitcoin in the world is about 12 million, that is to say, the two brothers hold about 120000 bitcoins< maybe you don't think it's worth much, but note that the starting price of bitcoin for these two people is less than $10 / bitcoin
Please note that entities are used instead of people. In the analysis method of this paper, bitcoin wallets that may belong to the same owner are divided into the same entity, which may be not only a person, but also a trading organization like Mt. GOx in addition, through the analysis of the most active entity table given in this paper, the income of the people with the most income (excluding expenses) is less than 700000 BTC. In other words, the person with the most bitcoin will hold no more than 700000 bitcoins. How many people in the world own bitcoins? The paper concludes that as of May 13, 2012, 1.85 million entities hold bitcoin. If we assume that bitcoin users have grown linearly since the advent of bitcoin (January 2009), the current number should be 2.5 million. Because the number of entities is counted on paper, the actual number of bitcoin holders should be a little less than this number, but not much smaller, because after all, there are not many large trading platforms
In addition to the above two problems, [3] also gives many interesting conclusions, such as: < UL >about 55% of bitcoin can be saved without money
in places like GOx mountain, almost all deals are small ones
before May 2012, almost all large single transactions (& gt; 50000 BTC) are subsequent transactions of 90000 BTC on November 8, 2011. There are very strange patterns in this long list of transactions. For example, an entity divides 90000 BTCs into different sizes, sends them back to itself three times, and then sells them on Mt. GOx. 90000 BTCs sold are sent back to the entity through 90 different bitcoin addresses, with 1000 bitcoins per address. These operations indicate that the entity appears to be trying to hide the relationship between these transactions
according to the currency conversion ratio on January 3, 2020, one bitcoin = RMB 47000
compared with fiat money, bitcoin has no centralized issuer. It is generated by the calculation of network nodes. Anyone can participate in the proction of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or receive bitcoin, And in the transaction process, foreigners can not identify the user's identity information
the global financial crisis broke out in 2008. On November 1, 2008, a person who called himself Satoshi Nakamoto published bitcoin white paper "bitcoin: a peer-to-peer e-cash system" on the P2P foundation website, stating a new idea for e-money bitcoin came out. On January 3, 2009, bitcoin Genesis block was born
whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses focused on whether bitcoin was a scam. Now the analysis focuses on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin

eg: This paper is completed under the careful guidance and strong support of teacher XX. Teacher X has a great influence on me with his rigorous and realistic academic attitude, high professional spirit, conscientious, assious work style and bold and innovative enterprising spirit. Her profound knowledge, broad vision and keen thinking give me deep enlightenment. At the same time, in this graation project process, I also learned a lot about microbial fermentation knowledge, experimental skills have been greatly improved.
there are three kinds of players:
1. Mining (procing bitcoin)
2. Investment (buying low and selling high to earn price difference)
3. Around bitcoin (such as procing mining machine to sell money, repairing mining machine to earn money, mining supporting business to earn money, etc.)
there is another kind, which belongs to the second category, but has a broad vision. It's the international pound. For example, the value of bitcoin in India is much higher than that in the world recently. Some people buy it in the world and sell it in India.
