What is a Stablecoin?
A stablecoin is a type of cryptocurrency designed to minimize price volatility by pegging its value to a stable asset, such as:
- Fiat currencies (e.g., the U.S. dollar)
- Commodities (e.g., gold)
- Other cryptocurrencies (via algorithmic mechanisms)
Unlike Bitcoin or Ethereum, which can fluctuate 10–20% daily, stablecoins provide the scalability, privacy, and decentralization of crypto while maintaining price stability—making them ideal for:
✅ Everyday payments
✅ Cross-border transactions
✅ Hedging against crypto market volatility
Why Stability Matters
- Practical Payments: Goods/services priced in fiat require stable mediums of exchange.
- Long-Term Holdings: Investors avoid assets that lose value unpredictably.
- Liquidity: Enables seamless trading between crypto and traditional markets.
Types of Stablecoins
1. Fiat-Collateralized Stablecoins
Backed 1:1 by reserves of fiat currency (e.g., USD). Examples:
- Tether (USDT)
- TrueUSD
- USD Coin (USDC)
Pros: High stability. Cons: Centralized custody risks.
2. Crypto-Collateralized Stablecoins
Decentralized but backed by other cryptocurrencies (e.g., Ether). Examples:
- Dai (DAI)
Pros: Transparency via blockchain audits. Cons: Complexity in collateral management.
3. Algorithmic Stablecoins
Use smart contracts to adjust supply dynamically (e.g., burning/minting tokens). Examples:
- Havven (now Synthetix)
Pros: No collateral needed. Cons: Higher risk of destabilization (see TerraUSD collapse).
