$BTC Bitcoin ($BTC) is the world’s first decentralized digital currency, introduced in 2009 by an anonymous individual or group under the name Satoshi Nakamoto. Operating without a central authority, Bitcoin uses a peer-to-peer network to validate transactions through a process called mining. This is powered by blockchain technology, which ensures transparency and security. Bitcoin is often referred to as “digital gold” due to its limited supply of 21 million coins and its role as a store of value. Over time, it has become both a speculative investment and a hedge against inflation. As global adoption grows, Bitcoin continues to influence financial systems, promote innovation, and challenge traditional monetary policies.
