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

in addition, the transaction of bitcoin is global, and it does not say in which region the transaction can take place. Therefore, no one should know how many bitcoins are traded in China. If you want to know how many bitcoins are traded in China, you can only see the disclosed data. The transaction of bitcoin itself is secret, so there must be some hidden ones, So the data is also inaccurate.
According to the information released yesterday by the office of the people's Government of Heshun County, Shanxi Province, a slope landslide accident occurred in the a6-1 mining area of the fourth mining area of Lvxin coal instry in the county from 15:00 to 17:00 on August 11.

Most people take money for granted and don't know its source, purpose and qualitative characteristics. In the atmosphere of ignorance is a blessing, they blindly spend the long history but familiar money in their daily life. I don't know that some digital currencies have become global currencies, that is cryptocurrency
money has a different personal meaning for everyone. For some, it's a convenient way to get or experience what you need
