Bitcoin (BTC) is the original cryptocurrency and the world’s first decentralized digital money. Created in 2009 by the pseudonymous Satoshi Nakamoto, Bitcoin enables peer-to-peer transactions without intermediaries, secured by a proof-of-work blockchain.

BTC is primarily used as a store of value, a medium of exchange, and a hedge against traditional financial systems. Its fixed supply of 21 million coins, decentralized consensus, and global adoption make it the flagship cryptocurrency and the standard benchmark for the entire crypto market.
