$USDC$USDC is a popular stablecoin and is often considered safe, there are still some notable negative aspects:

Centralization: USDC is issued by an organization (Circle), which means it is not completely decentralized. Circle can freeze or control wallets in certain cases.

Dependence on banks: USDC requires fiat USD reserves at traditional banks. When incidents occur such as bank failures (e.g., Silicon Valley Bank in 2023), USDC may temporarily lose its peg.

Legal risks: Due to operating in the US, USDC is susceptible to tightening regulations from the SEC or the government, causing concerns for international investors.

No natural yield: Unlike many other crypto assets, holding USDC does not generate yield unless staked or invested in DeFi – which carries its own risks.

In summary, while USDC is stable, it is not entirely "absolutely safe" as many people mistakenly believe.
