$BTC Bitcoin (BTC) is a decentralized digital currency, meaning it operates independently of any central bank or government. It was created in 2009 by an anonymous person or group known as Satoshi Nakamoto.

Here's how Bitcoin works:

* Blockchain technology: Bitcoin transactions are recorded on a public ledger called the blockchain. This ledger is distributed across a network of computers, making it transparent and secure.

* Decentralization: No single entity controls Bitcoin. Instead, it relies on a peer-to-peer network of users to verify and validate transactions.

* Limited supply: There will only ever be 21 million Bitcoins in existence. This scarcity can contribute to its value.

* Mining: New Bitcoins are created through a process called mining, where powerful computers solve complex mathematical problems to validate transactions and add them to the blockchain.

Bitcoin's value is highly volatile, meaning its price can fluctuate significantly. It's important to understand the risks involved before investing in Bitcoin.
