This guide explores the key differences between these stablecoins, their use cases, and how to choose the best option for your needs.
Types of Stablecoins
Stablecoins fall into three categories, ranked by risk:
Fiat-Collateralized (e.g., USDT, USDC, BUSD)
- Backed by fiat reserves (e.g., USD).
- Centralized issuers (e.g., Tether, Circle) must maintain 1:1 reserves.
- Risk: Lack of transparency in reserves (e.g., USDT’s audits have faced scrutiny).
Crypto-Collateralized (e.g., DAI)
- Overcollateralized by crypto assets (e.g., ETH).
- Decentralized and transparent via smart contracts.
- Risk: Volatility in collateral value may trigger liquidations.
Algorithmic (e.g., defunct UST)
- No collateral; relies on supply adjustments.
- Highest risk (e.g., Terra/LUNA collapse).
