Bitcoin (BTC) is the first cryptocurrency ever created, launched in January 2009. It is a decentralized Proof of Work digital currency native to its own blockchain. The creation of Bitcoin is attributed to a person called Satoshi Nakamoto, although this name was never officially associated with any real person. The mining and reward system of Bitcoin is planned from beginning to end. By the end of the production cycle, Bitcoin will reach its limit of 21 million coins. All Bitcoin transactions are carried out between independent network members without any third-party control, making Bitcoin a peer-to-peer cryptocurrency.
