What is Bitcoin?

Bitcoin is the first and most valuable cryptocurrency, created in 2009. It introduced blockchain technology and inspired thousands of alternative cryptocurrencies.

Bitcoin functions as digital gold—a store of value with a fixed supply cap of 21 million coins.

Satoshi Nakamoto

Bitcoin's creator remains anonymous, known only by the pseudonym "Satoshi Nakamoto." In October 2008, Satoshi published the Bitcoin whitepaper, describing a "peer-to-peer electronic cash system" that would allow online payments without financial intermediaries.

After launching Bitcoin and collaborating with early developers, Satoshi disappeared in 2011, leaving behind a functioning network and never revealing their identity.
