Bitcoin (BTC)

Bitcoin (BTC) is a digital form of money that operates without a central bank or government. It uses blockchain technology—an open, secure ledger shared across many computers—to record transactions transparently and prevent fraud. People can send and receive Bitcoin electronically, often for online purchases or investment. Its limited supply of 21 million coins makes it different from traditional currencies, and its decentralized nature means transactions are maintained collectively rather than controlled by any single entity. Bitcoin offers a peer-to-peer financial system that is transparent, secure, and resistant to censorship.
