Bitcoin, born on November 1, 2008, is a kind of virtual encryption digital currency in the form of P2P , which is composed of complex computer-generated code. Compared with other virtual currencies (q-coin and various game currencies are virtual currencies), the total amount of bitcoin is very limited , so it is more valuable. Moreover, based on the design of cryptography, bitcoin can only be transferred or paid by the real owner, which ensures the anonymity of currency ownership and circulation transactions
