BTC stands for Bitcoin, which is a type of digital or cryptocurrency. It was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. Bitcoin operates on a decentralized network of computers using blockchain technology, which ensures security and transparency of transactions.

Key features of Bitcoin include:

1. **Decentralization**: Unlike traditional currencies that are controlled by governments or financial institutions, Bitcoin is decentralized and not governed by any single entity.
  
2. **Blockchain Technology**: Transactions are recorded on a public ledger called the blockchain. This ledger is maintained by a network of computers (nodes) across the globe, making it nearly immutable and transparent.

3. **Limited Supply**: There will only ever be 21 million bitcoins in existence, a feature that aims to create scarcity and potentially increase value over time.

4. **Peer-to-Peer Transactions**: Bitcoin can be sent directly from user to user without the need for an intermediary, such as a bank or payment service provider.

5. **Anonymity and Pseudonymity**: Transactions can be made without revealing personal information, although they are not entirely anonymous since transactions can be traced back to wallet addresses.

6. **Volatility**: The price of Bitcoin is highly volatile and can fluctuate dramatically in short periods.

Bitcoin is used both as a digital currency and as an investment asset. People can buy, sell, and trade Bitcoin on various cryptocurrency exchanges, and some merchants accept it as a form of payment for goods and services.
