BTC is Bitcoin, and its full name is Bitcoin. The concept of Bitcoin was first put forward by Satoshi Nakamoto in 2009. According to Satoshi Nakamoto's idea, open source software and P2P network were designed and released. Bitcoin is a P2P digital currency. Point-to-point transmission means a decentralized payment system.

Bitcoin is different from most currencies. Bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations according to a specific algorithm. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transaction behaviors, and uses cryptography design to ensure the security of all links in currency circulation. The decentralized nature of P2P and the algorithm itself can ensure that the currency can not be manipulated artificially and create a large number of bitcoins. The design based on cryptography can make bitcoin only transferred or paid by the real owner. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is that its total amount is very limited and extremely scarce. The monetary system once did not exceed1050,000 for four years, and the total will be permanently limited to 21050,000.
