Bitcoin is a decentralized digital currency invented in 2008 by an anonymous person or group known as Satoshi Nakamoto.

It operates on a peer-to-peer network, allowing direct transactions without intermediaries like banks.

Bitcoin has a limited supply of 21 million coins, which contributes to its value as a store of value akin to gold.

Transactions are verified by nodes and recorded on the blockchain for security.

Bitcoin offers anonymity and ease of cross-border transactions but faces criticism for its volatility and association with illicit activities.

Regulation and acceptance vary worldwide. Institutional interest has brought legitimacy but also concerns of centralization.

Bitcoin's future hinges on scalability, transaction speed, cost, and mainstream acceptance.
