$BTC Bitcoin (BTC) is the world’s first and most popular cryptocurrency, revolutionizing digital finance. Operating on a decentralized blockchain, it allows secure, peer-to-peer transactions without intermediaries like banks. With a fixed supply of 21 million coins, BTC is often called "digital gold" due to its scarcity and store-of-value properties. Investors and institutions increasingly adopt Bitcoin as a hedge against inflation and economic uncertainty. Its price is highly volatile, creating opportunities for traders and long-term holders. As blockchain technology evolves, Bitcoin remains a dominant force in the crypto market, shaping the future of decentralized finance (DeFi) and global transactions.
