1. The Rise of Stablecoins: A Brief History
Early Experiments (2014–2017)
- Tether (USDT): Launched in 2014 as “Realcoin,” the first major USD-backed stablecoin.
- MakerDAO (DAI): Introduced in 2017 as the first decentralized stablecoin, collateralized by crypto assets.
Explosive Growth (2018–2024)
- Market cap surged from $3B (2018) to $160B+ (2024).
- USDC, BUSD, and algorithmic stablecoins entered the market.
- Adoption by exchanges, institutions, and remittance firms.
Why Stablecoins?
✅ Price stability in volatile crypto markets.
✅ Fast cross-border payments (cheaper than SWIFT).
✅ Liquidity engine for DeFi and trading.
2. Types of Stablecoins & How They Work
1. Fiat-Collateralized (Centralized)
- Backed 1:1 by cash reserves (e.g., USDT, USDC).
- Pros: High liquidity, trusted stability.
- Cons: Requires audits, centralized control.
2. Crypto-Collateralized (Decentralized)
- Overcollateralized with crypto (e.g., DAI).
- Pros: Trustless, censorship-resistant.
- Cons: Volatility risks, complex mechanisms.
3. Algorithmic (Non-Collateralized)
- Algorithmically adjusts supply (e.g., failed TerraUSD).
- Pros: Capital efficiency.
- Cons: Prone to death spirals (see Terra collapse).
| Type | Examples | Backing | Risk Level |
|---|---|---|---|
| Fiat-Collateralized | USDT, USDC | Bank reserves | Low-Medium |
| Crypto-Backed | DAI | ETH, WBTC | Medium-High |
| Algorithmic | (Formerly UST) | None (algorithm) | High |
