$BTC Bitcoin ($BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to verify and record transactions without the need for intermediaries like banks. Bitcoin is limited to 21 million coins, making it deflationary by design. Often referred to as “digital gold,” it is used as both a speculative investment and a store of value. Bitcoin’s price is highly volatile, influenced by market demand, regulation, adoption, and macroeconomic trends. It has sparked global interest in cryptocurrencies and blockchain-based financial innovation.
