$USDC USDC (USD Coin) is a stablecoin issued by Circle and is backed 1:1 by USD. It has high transparency, is regularly audited, and is widely used in DeFi, cross-border payments, and crypto trading. Compared to USDT, USDC is considered safer due to its transparent reserves and strict compliance with financial regulations. However, risks still exist, especially as Circle relies on the traditional banking system. In the future, USDC may expand its role, especially in CBDCs and blockchain payment solutions. Investors should monitor relevant regulatory policies.
