$USDC Trading pairs represent two assets you can exchange in a market, like BTC/USDT or ETH/BNB. The first asset (base) is what you're buying or selling, and the second (quote) is what you're using to make the trade. For example, in BTC/USDT, you're trading Bitcoin against Tether. Trading pairs help determine asset value in relative terms. Understanding pairs is essential for navigating both centralized and decentralized exchanges efficiently and making informed trading decisions. Always check liquidity and fees before trading.
