Understanding Cryptocurrency
Cryptocurrency is a digital currency that relies on cryptographic techniques for security and verification, operating independently of central authorities. Examples include Bitcoin, Litecoin, and BitShares. Key features:
- Decentralized: Uses peer-to-peer (P2P) technology for distribution.
- Secure: Transactions are encrypted and irreversible.
- Anonymous: Enables pseudonymous online payments.
Bitcoin remains the dominant cryptocurrency, recognized as legal tender in several countries.
