$BTC Bitcoin (BTC) is a decentralized digital currency, created in 2009 by an anonymous entity known as Satoshi Nakamoto. It operates on a technology called blockchain, a distributed public ledger that records all transactions across a network of computers. This decentralized nature means no single authority, like a central bank, controls Bitcoin.

Bitcoin's value has seen significant fluctuations since its inception. Initially worth less than a cent, it reached an all-time high of over $109,000 in late 2024. As of today, April 25, 2025, the price hovers around $93,000 - $94,000. Its market capitalization is substantial, recently surpassing $1.86 trillion, making it one of the largest assets globally.

The supply of Bitcoin is capped at 21 million coins, a feature designed to create scarcity. New Bitcoins are introduced into the system through a process called mining, where powerful computers solve complex mathematical problems to validate and add new blocks of transactions to the blockchain. Bitcoin can be used for online transactions and is traded on various cryptocurrency exchanges.
