Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency, launched 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 publicly and securely. Unlike traditional currencies, Bitcoin is not controlled by any central authority like a government or bank. Its limited supply—capped at 21 million coins—adds to its appeal as a store of value, often compared to digital gold. Bitcoin can be used for online purchases, investment, and as a hedge against inflation. Despite volatility, it has influenced the development of thousands of other cryptocurrencies and reshaped global finance.
