Bitcoin (₿) is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator,[7] though some researchers point at a trend towards centralization.[9]:215, 219–222[10]:3
Bitcoins can be sent from user to user on the peer-to-peer bitcoin network directly, without the need for intermediaries, though intermediaries are widely used.[9]:220–222 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[11] and released as open-source software in 2009.[12] Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[13] 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.[14]
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.[15] Several regulatory agencies have issued investor alerts about bitcoin.[16
