$BTC Bitcoin (BTC) is a decentralized digital currency, meaning it operates without a central bank or single administrator. Launched in 2009 by an anonymous entity known as Satoshi Nakamoto, it utilizes blockchain technology, a distributed public ledger that records all transactions securely and transparently.

Bitcoins are created through a process called "mining," where powerful computers solve complex mathematical problems. The supply of Bitcoin is finite, capped at 21 million coins, which contributes to its scarcity and perceived value as "digital gold."

Transactions are peer-to-peer, verified by network nodes through cryptography, and recorded on the blockchain. Bitcoin's price is highly volatile, influenced by factors like supply and demand, market sentiment, and regulatory news. It's used for online and offline transactions where accepted, and as an investment asset.
