What Are Stablecoins?
Stablecoins are cryptocurrencies pegged to "stable" assets like fiat currencies or commodities. The most common type maintains a 1:1 ratio with the US dollar—meaning one stablecoin theoretically equals one dollar. Examples include USDT (Tether), USDC (USD Coin), and PYUSD (PayPal USD).
With increasing global legislation and market adoption, stablecoins are gaining visibility as viable investment assets. Investors should consider incorporating them into diversified portfolios.
Why Stablecoins Matter
The Volatility Problem in Crypto
Cryptocurrencies like Bitcoin experience significant price swings, making them impractical for daily transactions. Imagine buying coffee with Bitcoin—tomorrow’s price could double or halve your purchase value.
Stability as the Core Value Proposition
Stablecoins address this by offering:
- Transaction Medium: Facilitate seamless trades between volatile crypto assets.
- Hedging Tool: Enable traders to exit risky positions quickly.
- Pricing Unit: Provide a stable reference for crypto services/products.
Types of Stablecoins
1. Fiat-Collateralized Stablecoins (Most Common)
- Mechanism: Backed 1:1 by fiat reserves (e.g., USD).
Examples:
- USDT: Largest by market cap.
- USDC: Prioritizes transparency/audits.
- PYUSD: PayPal’s offering, now on Solana blockchain.
- Pros: Low complexity, high stability.
- Risks: Reliance on issuer’s reserve audits.

2. Crypto-Collateralized Stablecoins
- Mechanism: Overcollateralized with other cryptos (e.g., ETH).
- Example: DAI (MakerDAO).
- Pros: Decentralized, transparent.
- Risks: Vulnerable to crypto market crashes.
3. Algorithmic Stablecoins
- Mechanism: Algorithmically adjusts supply/demand.
- Examples: Failed (UST), emergent (USDe by Ethena Labs).
- Pros: Capital-efficient.
- Risks: High failure risk ("death spiral").
