$BTC Bitcoin, often hailed as the first cryptocurrency, emerged in 2009, created by the pseudonymous Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network, eliminating the need for intermediaries like banks. Transactions are recorded on a public ledger called the blockchain, ensuring transparency and security.

Bitcoin's value is determined by market demand, leading to price volatility. Its limited supply of 21 million coins adds to its appeal as a potential store of value. Bitcoin has sparked innovation in finance and technology, influencing the development of numerous other cryptocurrencies and blockchain applications.
