BTC

Bitcoin is a decentralized digital currency launched in 2009 by the pseudonymous creator Satoshi Nakamoto and operates on a proof‑of‑work blockchain that records every transaction in a public, cryptographically secured ledger. Its primary purpose is to enable peer‑to‑peer electronic cash transfers without intermediaries while also serving as a digital store of value due to its fixed supply of 21 million coins. As the first and most widely recognized cryptocurrency, Bitcoin anchors the broader crypto ecosystem and is noted for its high security, strong decentralization, and role as a benchmark for digital scarcity.
