$BTC Bitcoin (BTC) has revolutionized finance by introducing a decentralized, peer-to-peer system that allows users to send and receive money globally without intermediaries like banks. Its open-source code and transparent ledger ensure security and trust through cryptographic proof rather than institutional authority. Bitcoin mining, the process of validating transactions and adding them to the blockchain, involves solving complex mathematical problems and consumes significant energy. Despite criticism for its volatility and environmental impact, Bitcoin is embraced by investors, institutions, and even some governments. It’s also seen as a store of value in uncertain economic times, driving global interest and ongoing innovation in crypto finance.
