Cities with the most bitcoin
There are only 21 million bitcoins
"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations
{rrrrrrr}
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
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
1) two American brothers, Cameron Winklevoss and Tyler Winklevoss, claim to hold about 1% of bitcoin in the world? Now the total amount of bitcoin in the world is about 12 million BTC, that is to say, these two brothers hold about 120000 bitcoins. Maybe you don't think these are too valuable, but note that the starting price of bitcoin for these two people is below $10 / BTC. At the current market price of $430 / BTC, the yield is...... (2) Li Xiaolai claims that he is the first person in China to hold bitcoin, holding six digit bitcoin (no video link found.)
3) after the founder of the silk road was arrested, his 140000 bitcoin was seized by the FBI [2]
therefore, the people who have the most bitcoin should hold more than 1% of the world's total. This can be seen from the daily BTC holdings list
more systematic research comes from academia. The Israeli mathematician ADI Shamir (if the name is unfamiliar, he is the s in RSA algorithm) published a paper "quantitative analysis of the full bitcoin
transaction graph" in 2012, which analyzed the transaction records of the first 18000 blocks in the special currency system (as of May 13, 2012), This paper studies some interesting problems in bitcoin market
in their analysis results, at the end of the first 18000 blocks of chain, the entities with the most bitcoin holdings range from 200000 to 400000 BTC (the article does not give specific figures), and only one entity with more than 200000 bitcoin holdings. In history, the largest amount of money held was more than 500000 BTC, with two entities
note that "entity" is used instead of "person". In the analysis method of this paper, bitcoin wallets that may belong to the same owner are classified as the same entity. This entity may not only be a person, but also be a trading organization such as Mt. GOx
in addition, by analyzing the table of the most active entities given in the article, the income of the people with the most income (excluding expenses) is below 700000 BTC. In other words, the person who owns the most bitcoin will not hold more than 700000 BTC
