13 bitcoins
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
Recently, logic thinking & amp; The video of APP founder Luo Zhenyu talking about his investment in bitcoin was exposed again. In the video, Luo Zhenyu said that because he believed in the trend, he bought 100 bitcoins, which are now worth 3 million
LUO Zhenyu said that the simplest way to invest is: as long as you believe in the trend, you don't care after investing. It's more important to increase your ability to earn money

on December 17, 2017, bitcoin reached an all-time high of $19850
The concept of 21 million
bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million

generation principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

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
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
with the continuous popularity of bitcoin among cyber criminals and its growing presence in criminal activities, "Uncle Sam" (personified name in the United States) has become an important participant in the cryptocurrency market. Although the exact number cannot be determined, according to the documentary evidence and previous and current interviews with defense lawyers and prosecutors, there is at least one billion US dollars worth of digital currency, which is currently under the control of US law enforcement agencies
the investment method of bitcoin is very simple. Search "tacu Asian Stock Exchange". After registering and logging in, follow the prompts to invest in bitcoin. Now you can also give free digital currency for registration. This is a transaction registered in Thailand. The Thai royal family has a share in the transaction, and the credit is guaranteed. I registered on this platform and sent 1000 coins, with a maximum value of more than 10000 yuan. If you have other problems you don't understand, you can solve them by contacting customer service directly.
