Stablecoins have become indispensable in the crypto ecosystem, offering price stability amidst market volatility. Among the top contenders—USDT (Tether), USDC (USD Coin), and DAI (now USDS)—each serves distinct purposes with unique mechanisms. This guide compares their features, transparency, and use cases to help you make an informed choice.
What Are Stablecoins?
Stablecoins are cryptocurrencies pegged to stable assets like fiat currencies (e.g., USD) or commodities. They merge crypto’s decentralization and efficiency with traditional asset stability. The three most widely adopted stablecoins are:
- USDT: The pioneer, launched in 2014, known for high liquidity but criticized for opacity.
- USDC: Launched in 2018, prized for regulatory compliance and transparency.
- USDS (formerly DAI): A decentralized, overcollateralized stablecoin governed by MakerDAO.
Key Differences Between USDT, USDC, and USDS
