Bitcoin (BTC), also known by its abbreviation XBT, is considered by some as a decentralized digital cryptocurrency, while most countries classify it as a virtual commodity rather than official currency. Created by the pseudonymous Satoshi Nakamoto on January 3, 2009, Bitcoin operates on a peer-to-peer network using consensus-driven open-source software.
Key Features of Bitcoin
- Decentralized System: No central authority controls Bitcoin transactions.
- Limited Supply: Capped at 21 million coins to prevent inflation.
- Direct Transactions: Users can send payments without intermediaries like banks, reducing fees and processing delays.
