Understanding Cryptocurrency
Cryptocurrency (or "crypto") is a digital currency designed for online payments and value storage. Unlike traditional electronic payment systems (credit cards, PayPal) that use government-issued fiat currencies, cryptocurrencies operate independently through decentralized blockchain technology.
Key Characteristics:
✅ Decentralized: No central authority controls supply
✅ Algorithmic Supply: Limited creation through cryptographic rules
✅ Blockchain-Based: Secure public ledger of all transactions
The "Crypto" in Cryptocurrency
The term refers to advanced cryptography—complex software protocols that secure transactions and control currency creation.
How Cryptocurrencies Operate
Cryptocurrencies rely on blockchain technology:
- Public Ledger: Distributed across thousands of computers
- Immutable Records: Transactions form unalterable "blocks"
