What Is a Stablecoin?
Stablecoins are cryptocurrencies designed to combine the benefits of blockchain technology with price stability. Unlike volatile assets like Bitcoin, stablecoins maintain a steady value by pegging to stable assets such as fiat currencies (e.g., USD), commodities, or other cryptocurrencies.
Types of Stablecoins:
Fiat-Collateralized
- Backed by traditional currencies (e.g., USDC, USDT).
- Example: $1 USD reserves for each token issued.
Crypto-Collateralized
- Backed by other cryptocurrencies (e.g., DAI).
- Example: Overcollateralization to absorb price fluctuations.
Commodity-Backed
- Pegged to physical assets like gold (e.g., PAX Gold).
- Example: 1 token = 1 troy ounce of gold.
Algorithmic
- Stability maintained via smart contracts (e.g., former TerraUSD).
- Example: Adjusts supply dynamically based on demand.
