What is BITCOIN






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.

 Transactions are verified by network nodesthrough 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 and was released as open-source software in 2009. Bitcoins are created as a reward for a process know as mining. They can be exchanged for other currencies, products, and services.Research produced by 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.
Bitcoin has been criticized for its use in illegal transactions, its high electricity consumption, price volatility, thefts from exchanges, and by reputable economists stating that "it should have a zero price".Bitcoin has also been used as an investment, although several regulatory agencies have issued investor alerts about bitcoin.
