📊 Understanding Stablecoins: Core Features and Types
1. Value Pegging Mechanisms
Stablecoins maintain price stability through various collateral models:
Fiat-Collateralized (e.g., USDT, USDC):
- Backed 1:1 by USD reserves in banks or short-term Treasuries
- Example: Each USDT theoretically equals $1 in reserve
Crypto-Collateralized (e.g., DAI):
- Overcollateralized with crypto assets (150%-200% ratios)
- Governed by smart contracts for automatic risk adjustment
Commodity-Backed (e.g., PAXG):
- Pegged to physical assets like gold
- 1 PAXG = 1 troy ounce of gold
Algorithmic (Historical example: UST):
- No physical collateral, relying on supply-demand algorithms
- High-risk (see TerraUSD collapse case study)
2. Primary Use Cases
- Hedge Against Volatility: Convert volatile crypto to stablecoins during market dips
- Trading Pair Standard: Most exchanges use stablecoin pairs (e.g., BTC/USDT)
- Cross-Border Payments: Near-instant transfers with minimal fees vs. traditional banking
