$BTC
Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It operates without a central authority, using blockchain technology—a public, transparent ledger that records all transactions. Bitcoin allows peer-to-peer transactions globally, with low fees and no need for banks. It is limited to 21 million coins, making it scarce and often seen as "digital gold." Bitcoin is widely used for investment, online purchases, and as a hedge against inflation. Its price is highly volatile, and it plays a major role in the growing world of cryptocurrencies.
