What is BTC Bitcoin?
Bitcoin (abbreviated as BTC or XBT) is a peer-to-peer decentralized cryptocurrency that operates on blockchain technology. Created by the pseudonymous Satoshi Nakamoto in 2008, Bitcoin introduced a groundbreaking digital payment system independent of central authorities. Its genesis block was mined on January 3, 2009.
Unlike traditional currencies, Bitcoin is often classified as a virtual commodity rather than legal tender in many jurisdictions. Its decentralized nature allows users to transact directly without intermediaries like banks, reducing fees and bypassing regulatory hurdles.
