What Is Bitcoin?
Bitcoin is a decentralized electronic payment system powered by cryptographic proof, enabling direct peer-to-peer transactions without intermediaries. It introduced the world’s first cryptocurrency—bitcoin (BTC)—which functions as a digital store of value (like gold) and a medium for online transfers. Created by the pseudonymous Satoshi Nakamoto, Bitcoin eliminates reliance on financial institutions by allowing users to transact globally with minimal friction.
Key Features of Bitcoin:
- Decentralized: No central authority controls the network.
- Peer-to-Peer: Transactions occur directly between users.
- Fixed Supply: Capped at 21 million BTC, ensuring scarcity.
- Divisible: Each BTC can be split into 100 million satoshis.
