Introduction
Stablecoins are cryptocurrencies designed to maintain a stable value by pegging them to assets like the US dollar. Among the most popular fiat-backed stablecoins are Tether (USDT) and USD Coin (USDC). This guide explores their features, similarities, differences, and key considerations for users.
What Are Stablecoins? How Do They Work?
Stablecoins are low-volatility cryptocurrencies backed by real-world assets, such as fiat currencies (e.g., the US dollar). They aim to reduce the price volatility seen in cryptocurrencies like Bitcoin.
Types of Stablecoins:
- Fiat-backed: Reserved in traditional currencies (e.g., USDT, USDC).
- Crypto-backed: Collateralized by other cryptocurrencies.
- Algorithmic: Use smart contracts to maintain stability.
Fiat-backed stablecoins hold reserves equivalent to their circulating supply, managed by centralized entities that conduct regular audits for transparency.
