$BTC Bitcoin (BTC) is the world's first and largest decentralized digital currency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. Unlike traditional money, it operates without a central bank or government, relying on a technology called blockchain.

Every Bitcoin transaction is recorded on this public, distributed ledger, secured by cryptography. This peer-to-peer system allows individuals to send and receive payments directly, bypassing intermediaries. While initially envisioned as digital cash, Bitcoin is now largely seen as a store of value, often dubbed "digital gold," and has gained significant popularity as both an investment and a medium of exchange in various sectors. Its limited supply of 21 million coins contributes to its perceived scarcity.
