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, which allows secure, transparent, and immutable transactions without the need for a central authority. Bitcoin’s total supply is capped at 21 million coins, making it inherently scarce and often referred to as “digital gold.” Users can send and receive BTC globally with relatively low fees compared to traditional banking systems, though transaction speeds can vary based on network congestion. BTC has become a store of value, investment asset, and medium of exchange, inspiring thousands of other cryptocurrencies. Its price is highly volatile, influenced by adoption, regulatory news, and macroeconomic factors, yet it remains the benchmark for the entire crypto market. Bitcoin also underpins an ecosystem of wallets, exchanges, and financial products, making it central to the growing digital finance space.
