What is Cryptocurrency?
Cryptocurrency is a decentralized digital currency designed to work as a medium of exchange using cryptography to secure transactions and control the creation of new units. Unlike traditional currencies issued by governments (fiat money), cryptocurrencies operate on blockchain technology—a distributed ledger enforced by a network of computers.
Key characteristics:
- Decentralization: No central authority controls the currency.
- Anonymity: Transactions can occur pseudonymously.
- Scarcity: Most have fixed maximum supplies (e.g., Bitcoin's 21 million cap).
- Security: Cryptographic protocols prevent double-spending and fraud.
