$USDC
As of Friday, June 6, 2025, the USDC-USDT pair remains incredibly stable, reflecting their core purpose as stablecoins.
* Exchange Rate: 1 USDC is consistently trading at or very near 1.00 USDT across major exchanges. You might see tiny fluctuations (e.g., 0.9993 USDT or 1.0001 USDT), but these are minimal and quickly corrected by arbitrage.
* Trading Volume: The 24-hour trading volume for the USDC/USDT pair on Binance alone is around $2 Billion USD, showing extremely high liquidity and constant movement between the two. Other exchanges also contribute significantly to this volume.
Essentially, it's a very active pair, but the goal for both tokens is to maintain their dollar peg, and they are largely succeeding in that. Any slight deviations are usually fleeting arbitrage opportunities.
