$USDC The USDC/USDT coin pair represents the exchange rate between two leading stablecoins—USD Coin (USDC) and Tether (USDT)—both pegged to the U.S. dollar. This trading pair is commonly used in crypto markets for liquidity management, arbitrage, and stablecoin diversification. Although both aim to maintain a 1:1 value with the dollar, slight price differences can occur due to factors like market demand, transparency, and reserve backing. Traders often use the USDC/USDT pair to hedge or switch between stablecoins based on trust and platform preference, making it a vital tool in crypto trading strategies and stable asset management.
