Peg mechanisms explained

Fiat-backed stablecoins (USDT, USDC) hold cash and treasuries with a custodian. Crypto-backed coins (DAI) are over-collateralized with on-chain assets. Algorithmic designs rely on incentives alone and have the worst historical track record — Terra's UST collapse in 2022 erased ~$40B. Mechanism matters more than market cap when judging risk.
