$BTC Bitcoin ($BTC) is the world’s first and most valuable cryptocurrency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a decentralized blockchain network, allowing peer-to-peer transactions without intermediaries like banks. Bitcoin is limited to 21 million coins, making it a deflationary asset. It's often called "digital gold" due to its store-of-value properties. Over time, $BTC has gained institutional interest and global recognition, driving both adoption and price volatility. Investors use Bitcoin as a hedge against inflation, and it plays a central role in the broader crypto ecosystem. Its market movements often influence other crypto assets.
