$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group using the name Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which records all transactions transparently and securely. Unlike traditional currencies, Bitcoin is not controlled by any government or central bank. It is mined through a process that involves solving complex mathematical problems using computer power. Bitcoin is often used for investment, online transactions, and as a store of value. Its limited supply of 21 million coins contributes to its scarcity and appeal in the digital economy.
