What Are the Three Main Types of Stablecoins (Fiat-Backed, Crypto-Backed, Algorithmic)?

Fiat-backed stablecoins (like USDC) are collateralized 1:1 by traditional currency reserves. Crypto-backed stablecoins (like DAI) are over-collateralized by volatile crypto assets.

Algorithmic stablecoins (like older UST models) use smart contracts and seigniorage to maintain their peg without direct external collateral.
