Stablecoins have become a cornerstone of the cryptocurrency ecosystem. But what exactly are they, and why are they important? This comprehensive guide explores the four main types of stablecoins, their uses, and how they work.
What Is a Stablecoin (Stablecoin)?
A stablecoin is a cryptocurrency pegged to the value of a real-world asset, primarily the US dollar. For example, USDT is a dollar-pegged stablecoin where 1 USDT equals $1. Think of stablecoins as the "fiat currency" of the crypto world.
Why Does the Market Need Stablecoins? 3 Key Uses
Cryptocurrencies like Bitcoin are known for their volatility, making them less ideal for everyday transactions or value storage. Stablecoins solve this problem by offering:
- Payment and Transactions
Stablecoins facilitate seamless crypto-to-fiat conversions, fee payments, and trading. Users often convert volatile assets into stablecoins before cashing out. - Value Storage
During market downturns, investors shift funds into stablecoins to preserve capital until conditions improve. - Pricing Benchmark
Dollar-pegged stablecoins (e.g., USDT) provide a stable reference point for valuing other cryptocurrencies. For instance, ETH/USDT pairs clearly show Ethereum's dollar value.

The 4 Types of Stablecoins Explained
1. Fiat-Collateralized Stablecoins
Backed 1:1 by fiat reserves (e.g., USD). Examples:
- USDT (Tether)
- USDC (Circle)
- BUSD (Binance)
How they work: Issuers hold equivalent fiat reserves to ensure peg stability.
2. Crypto-Collateralized Stablecoins
Overcollateralized with cryptocurrencies (e.g., ETH). Example:
- DAI (150% collateralized via MakerDAO)
Key feature: Decentralized but requires higher collateral to absorb price swings.
3. Algorithmic Stablecoins
Use smart contracts to adjust supply and maintain pegs. Examples:
- UST (defunct; Terra collapse)
- USDD
Risk note: Highly dependent on market confidence—prone to "death spirals" if trust erodes.
4. Commodity-Backed Stablecoins
Pegged to physical assets like gold. Examples:
- PAXG (1 token = 1 oz gold)
- XAUT
Use case: Combines gold's stability with blockchain's liquidity.

Stablecoin Risks to Consider

- Regulatory uncertainty: Governments are increasing oversight of stablecoin issuers.

Q: Can stablecoins earn interest?
A: Yes! Platforms like OKX offer yield-bearing stablecoin products.
Q: What happens if a stablecoin loses its peg?
