Bitcoin is a decentralized digital currency, also known as a cryptocurrency. It operates without a central authority or intermediary, relying instead on a peer-to-peer network and blockchain technology to facilitate and record transactions securely. Key characteristics of Bitcoin include:

1. **Decentralization**: No central bank or single administrator controls Bitcoin.

2. **Blockchain Technology**: Transactions are recorded on a public ledger called the blockchain, which is maintained by a network of nodes (computers).

3. **Limited Supply**: There will only ever be 21 million Bitcoins, making it deflationary in nature.

4. **Cryptographic Security**: Transactions and issuance are managed through cryptographic algorithms, ensuring security and integrity.

5. **Pseudonymity**: Users can transact without revealing their real identities, though transactions are publicly recorded on the blockchain. $BTC
