$BTC Bitcoin ($BTC) is the world’s first and most popular cryptocurrency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network called the blockchain, which records all transactions securely and transparently. Unlike traditional currencies, Bitcoin is not controlled by any government or central authority. Its value is driven by supply and demand, investor interest, adoption, and market sentiment. Bitcoin is often seen as digital gold due to its limited supply of 21 million coins. It’s used for investment, online purchases, and as a store of value in the digital economy.
