$BTC Bitcoin (BTC) is a decentralized digital currency, meaning it operates without a central bank or government control. Created in 2009 by an anonymous entity known as Satoshi Nakamoto, it introduced the concept of cryptocurrency.

Bitcoin transactions are recorded on a public, immutable ledger called a blockchain. This distributed network is maintained by "miners" who verify transactions and add new blocks, earning new bitcoins in the process. Its limited supply of 21 million coins and peer-to-peer nature aim to offer a secure, transparent, and censorship-resistant alternative to traditional financial systems. BTC can be used for payments or as a store of value.
