$BTC Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a peer-to-peer network without the need for intermediaries like banks or governments. Bitcoin transactions are verified by miners and recorded on a public blockchain ledger, making it transparent and secure. With a fixed supply of 21 million coins, Bitcoin is often referred to as "digital gold" due to its scarcity and store-of-value characteristics. Over time, BTC has evolved from a niche technology to a global financial asset, attracting institutional investors and serving as a hedge against inflation and currency devaluation.
