Stablecoins serve as price-stable assets (not currencies) designed to minimize volatility, acting as reliable account units and value storage. When crypto markets fluctuate, holders often convert assets into stablecoins to preserve value.
While bridging fiat and cryptocurrencies effectively—especially for commerce and cross-border transactions—stablecoins aren't flawless. Fiat currencies also fluctuate, but cryptocurrencies exhibit extreme volatility ranges.
Types of Stablecoins
- Fiat-Collateralized: Backed 1:1 by reserves like USD (e.g., USDT, TrueUSD).
- Commodity-Collateralized: Pegged to assets like gold (e.g., DGX).
- Crypto-Collateralized: Backed by other cryptocurrencies (e.g., DAI).
- Algorithmic: Non-collateralized, using supply adjustments (e.g., Basis, USDX).
