$BTC Bitcoin (BTC), the world’s first and most widely recognized cryptocurrency, continues to play a central role in the evolving digital asset ecosystem. As a decentralized currency, Bitcoin operates without central bank control, relying instead on a global network of nodes and miners to validate transactions and secure the blockchain. Its fixed supply of 21 million coins contributes to its appeal as a hedge against inflation and monetary policy uncertainty. In recent market movements, BTC's price often reflects investor sentiment toward macroeconomic conditions, regulatory developments, and technological innovations within the crypto space. As institutional adoption grows and layer-two solutions like the Lightning Network expand, Bitcoin remains a foundational asset in both speculative trading and the long-term vision of decentralized finance.
