$USDC
As of June 2025, USD Coin (USDC) remains one of the most trusted and widely used stablecoins, backed 1:1 by the U.S. dollar and issued by Circle. It continues to play a crucial role in crypto trading, DeFi platforms, and cross-border payments. With increasing regulatory clarity in the U.S. and Europe, USDC adoption has grown among institutions and fintech companies. Circle’s expansion into tokenized treasury products and integration with traditional banks has strengthened USDC’s credibility. Although Tether (USDT) still dominates in volume, USDC is preferred for transparency and regulatory compliance, making it a reliable option for stable digital transactions.
