A $USDC coin pair refers to trading a cryptocurrency against USD Coin ($USDC) on an exchange. For example, in a BTC/USDC pair, you're exchanging Bitcoin for USDC. This is increasingly popular because USDC, being a stablecoin pegged 1:1 to the US Dollar, offers stability in the volatile crypto market.

Trading with $USDC pairs allows for quick, reliable transactions and acts as a safe haven during market downturns. It provides deep liquidity across major exchanges and is widely used in both decentralized (DeFi) and centralized (CeFi) finance for trading, lending, and yield farming. It's an ideal choice for traders looking to mitigate volatility or park funds on-chain while retaining dollar-equivalent value.
