$BTC Bitcoin (BTC) is the world's first decentralized digital currency, introduced in 2009 by the pseudonymous creator Satoshi Nakamoto. It operates without a central authority, using blockchain technology to record and verify transactions across a distributed network of computers. Bitcoin can be used for peer-to-peer transactions, store of value, or as an investment asset. Its supply is capped at 21 million coins, making it deflationary by design. Bitcoin mining, a process involving solving complex mathematical problems, secures the network and issues new coins. Over time, Bitcoin has gained significant attention from investors, institutions, and governments, influencing the broader cryptocurrency market.
