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

5. According to the current bitcoin price of the coin egg network, one bitcoin is 51112 yuan, and the number of non small bitcoins is 17051175. We do a multiplication (unit price multiplied by quantity) to get about 871.5 billion
explain why it's left and right, because the price of each platform is different, so there will be some differences, but the fluctuation will not be too large. There is also a total of 21 million bitcoins, but there are still many that have not been g up so far, so when we calculate the market value, we just calculate the total current value.

About 400 percent

when bitcoin first appeared in 2009, one dollar could buy almost 1300 bitcoins. Before April 2011, the price of each bitcoin was always below $1. In June 2011, the highest price of bitcoin rose to $30. Then, the price almost fell within a week. In 2012, the price of bitcoin once fell below $2

further dropped to $114 on January 14, 2015. Since then, bitcoin has begun to rise again. In 2017, after the bitcoin ETF fund was rejected by the US Securities Regulatory Commission, bitcoin plummeted by $315 to below $1000. After that, it rose again. In the first four months of this year, the price of bitcoin and an ounce of gold were almost equal

However, with the strong rise of bitcoin in this round, the price of bitcoin has exceeded the price of an ounce of gold. On April 26, the price of bitcoin was $1282.97, compared with $1264 for an ounce of gold. Bitcoin has surpassed gold in price
