$BTC Bitcoin (BTC) is the first decentralized digital currency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on blockchain technology, a distributed ledger that ensures transparency and security. Unlike traditional currencies, Bitcoin is not controlled by any central authority, making it resistant to inflation and censorship. Transactions are verified by a network of miners using a proof-of-work system, which also maintains the network's integrity. Bitcoin is widely used for payments, investments, and as a store of value. Its limited supply of 21 million coins and global acceptance make it a significant asset in the cryptocurrency ecosystem.
