Stablecoins serve as the backbone of the crypto market, offering digital assets designed to counteract the volatility typical of cryptocurrencies. Among the most popular options are USD Coin (USDC) and Tether (USDT), both pegged to the US dollar but differing in key aspects like backing, compliance, and market dynamics. This guide dives deep into their differences to help you decide which aligns best with your portfolio.
What Is a Fiat-Backed Stablecoin?
Fiat-backed stablecoins are cryptocurrencies pegged 1:1 to traditional currencies like the US dollar. They maintain price stability by holding reserves in cash, Treasury bills, or other liquid assets. Unlike volatile assets (e.g., Bitcoin), stablecoins are ideal for:
- Daily transactions
- Cross-border payments
- Parking funds securely
Major stablecoins like USDT and USDC rely on regulated custodians for reserve management, ensuring their peg remains stable across blockchain networks.
