正文部分

Bitcoin (₿) is a cryptocurrency， a form of electronic cash。 It is a decentralized digital currency without a central bank or single administrator that can be sent from user-to-user on the peer-to-peer bitcoin network without the need for intermediaries。[7]

Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain。 Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto[9] and released as open-source software in 2009。[10] Bitcoins are created as a reward for a process known as mining。 They can be exchanged for other currencies，[11] products， and services。 Research produced by the University of Cambridge estimates that in 2017， there were 2。9 to 5。8 million unique users using a cryptocurrency wallet， most of them using bitcoin。[12]

Bitcoin has been criticized for its use in illegal transactions， its high electricity consumption， price volatility， thefts from exchanges， and the possibility that bitcoin is an economic bubble。[13] Bitcoin has also been used as an investment， although several regulatory agencies have issued investor alerts about bitcoin。[14]
