#BTC Bitcoin (BTC) is the first and most popular cryptocurrency, created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto. It operates on a decentralized blockchain network, allowing secure and transparent peer-to-peer transactions without the need for intermediaries like banks. Bitcoin uses a proof-of-work consensus mechanism, where miners validate transactions and secure the network by solving complex cryptographic puzzles. Its supply is limited to 21 million coins, making it a deflationary asset. Bitcoin is often referred to as "digital gold" due to its store of value and potential as a hedge against inflation. It has revolutionized global finance.
