$USDC USDC/USDT is a popular cryptocurrency trading pair that represents the exchange rate between USD Coin (USDC) and Tether (USDT), two of the most widely used stablecoins in the crypto market. Both tokens are pegged 1:1 to the US dollar, offering price stability compared to volatile assets like Bitcoin or Ethereum. Traders often use this pair for arbitrage opportunities, hedging, or moving funds between exchanges with lower slippage. USDC, issued by Circle, is known for its transparency and regulatory compliance, while USDT, issued by Tether, is the largest stablecoin by market cap but has faced scrutiny over its reserves. The USDC/USDT pair typically trades close to parity, with minor deviations due to liquidity differences or market demand.
