$BTC , or Bitcoin, is the first and most well-known cryptocurrency, often referred to as digital gold. Launched in 2009 by the pseudonymous creator Satoshi Nakamoto, Bitcoin operates on a decentralized blockchain, enabling peer-to-peer transactions without the need for intermediaries. With a fixed supply of 21 million coins, $BTC is considered a hedge against inflation and currency devaluation. It is widely used for investment, store of value, and increasingly as a payment method. Bitcoin’s price is highly volatile, influenced by market demand, global economic trends, and regulatory news. As the flagship crypto, $BTC remains the cornerstone of the digital asset space.
