$BTC Bitcoin (BTC) –

Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized, peer-to-peer blockchain network without the need for central banks or intermediaries. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins and its use as a store of value. Transactions are verified by miners through a process called proof-of-work. BTC is widely traded globally and accepted by some merchants, though price volatility remains high. It has sparked debates over regulation, energy use, and its role in the future of finance.
