$BTC Bitcoin (BTC) is a decentralized digital currency created in 2009 by an unknown person or group using the pseudonym Satoshi Nakamoto. It allows peer-to-peer transactions without the need for intermediaries like banks or governments. Bitcoin runs on a blockchain, a public and transparent ledger that records all transactions. This blockchain is maintained by a network of computers (called nodes) that use a consensus mechanism known as Proof of Work to validate and secure transactions.

Bitcoin is often described as digital gold due to its limited supply—only 21 million BTC will ever exist. This scarcity, combined with increasing demand, contributes to its value. People use Bitcoin for various purposes: as an investment, a store of value, or even as a means of transferring money globally with relatively low fees.
