Bitcoin (BTC) is a decentralized digital currency created in 2009 by the pseudonymous Satoshi Nakamoto. It operates without a central authority, relying on blockchain technology to record transactions securely and transparently. Bitcoin’s total supply is capped at 21 million coins, making it scarce like digital gold. Transactions are confirmed through mining, where computers solve complex problems to add blocks to the blockchain. Bitcoin is divisible into smaller units called satoshis, allowing for microtransactions. It is used for payments, investment, and as a hedge against inflation. Despite price volatility, Bitcoin remains the leading cryptocurrency and a symbol of financial innovation worldwide.$BTC
