$BTC

Bitcoin ($BTC) is a decentralized digital currency that was introduced in 2009 by the pseudonymous creator Satoshi Nakamoto. Unlike traditional currencies, Bitcoin operates without a central bank or government, relying instead on blockchain technology to record transactions on a public ledger. It uses a consensus mechanism called proof-of-work, where miners verify transactions and are rewarded with newly minted bitcoins. The total supply is capped at 21 million, contributing to its scarcity and value proposition as "digital gold." Bitcoin is used for peer-to-peer payments, investment, and as a hedge against inflation. Its price can be highly volatile, driven by market speculation, regulatory news, adoption rates, and macroeconomic trends. Supporters view Bitcoin as a revolutionary tool for financial freedom and privacy, while critics point to its energy consumption and potential use in illegal activities. Despite the debate, Bitcoin remains a dominant force in the cryptocurrency space and a symbol of the broader decentralized finance movement.
