$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the pseudonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, allowing secure and transparent transactions without a central authority. Bitcoin is often seen as “digital gold” due to its limited supply of 21 million coins, making it a hedge against inflation for some investors. Its price is highly volatile, influenced by market sentiment, regulations, and macroeconomic factors. Bitcoin has sparked the creation of thousands of alternative cryptocurrencies and continues to play a central role in the evolution of digital finance.
