$BTC

Bitcoin ($BTC) is the first decentralized cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. Operating on blockchain technology, it enables peer-to-peer transactions without intermediaries like banks. With a fixed supply of 21 million coins, Bitcoin is often called "digital gold" due to its scarcity and store-of-value properties. Its price is highly volatile, driven by adoption, regulation, and macroeconomic trends. Major institutions now recognize Bitcoin as an asset class, while some governments accept it as legal tender. Despite criticisms over energy use and speculation, Bitcoin remains the dominant cryptocurrency, shaping the future of finance and decentralized technology.
