About Bitcoin
Bitcoin is a cryptocurrency that was launched in 2009 as open-source software by an individual or group of developers called Satoshi Nakamoto. Also, it is the first decentralized cryptocurrency.

Any transaction done using bitcoins is verified by a network node and recorded in a public ledger called blockchain.
