Bitcoin (BTC) is the first known and decentralized cryptocurrency created by an unrevealed person or group called Satoshi Nakamoto in 2009. The concept of Bitcoin lies in the opportunity for peer to peer transactions of digital money with no need for any middle party like banks. These transactions are processed by network nodes and recorded in blockchain digital and public ledger. Bitcoins are unable to be printed as FIAT money; they are mined and do not have a physical form. Mining is a process of adding transaction records to the blockchain; or, in simple terms, working out computationally difficult problems by computer software.
