$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 network using blockchain technology, enabling secure, transparent transactions without intermediaries like banks. Bitcoin has a capped supply of 21 million coins, making it deflationary in nature. Often seen as "digital gold," BTC is used both as a store of value and a speculative investment. Its price is highly volatile, influenced by market sentiment, regulation, and macroeconomic trends. Bitcoin continues to drive innovation in the crypto space and remains a benchmark for the broader digital asset market.
