$BTC
Bitcoin is the first decentralized cryptocurrency. Based on a free-market ideology, bitcoin was invented in 2008 by Satoshi Nakamoto, an unknown entity. Use of bitcoin as a currency began in 2009, with the release of its open-source implementation. In 2021, El Salvador adopted it as legal tender.
Bitcoin (BTC) is the first cryptocurrency built on blockchain technology, also known as a decentralized digital currency that is based on cryptography. Unlike government-issued or fiat currencies such as US Dollars or Euro which are controlled by central banks, Bitcoin can operate without the need of a central authority like a central bank or a company. The decentralized nature allows it to operate on a peer-to-peer network whereby users are able to send funds to each other without going through intermediaries.
