$BTC Bitcoin (Bitcoin, abbreviated as BTC) is a decentralized digital currency proposed by Satoshi Nakamoto in 2008 and officially launched in 2009. It is the world's first successfully implemented cryptocurrency, operating on blockchain technology with characteristics such as decentralization, anonymity, and immutability.

### Core Features of Bitcoin:

1. **Decentralization**: No central bank or institution controls it; it is maintained by global nodes collectively.

2. **Fixed Supply**: The cap is 21 million coins, expected to be fully mined around 2140.

3. **Blockchain Technology**: Transaction records are public, transparent, and immutable.

4. **Mining Mechanism**: Transactions are verified and new coins are generated through computational competition (PoW consensus mechanism).

5. **Anonymity**: Wallet addresses are not directly linked to identities, but transactions can be traced.

### Current Bitcoin Data (as of October 2023):

- **Price**: Approximately $27,000 (actual price should refer to real-time data, such as CoinMarketCap or Binance).
