What Is Crypto?

- Peer-to-peer transfers eliminate intermediaries like banks.
- Decentralization means no central authority controls the network (e.g., US dollars are regulated by the Federal Reserve).

How Cryptocurrency Works
Core Mechanics
- Encryption: The "crypto" in cryptocurrency refers to cryptographic codes securing transactions.

Value Proposition
Cryptocurrencies derive value from:
- Supply/demand dynamics
- Utility (e.g., Ethereum's smart contracts)
