USDC was good for a while, and is also good for small transfers from exchange A to exchange B, but it is recommended that you immediately exchange it to some other tokens and not keep it as it is as it's still a stablecoin wherein they can do what they want. No reports of USDC being frozen or anything, but just to be safe.
IMO USDC depends how someone use it. If you have USDC stored on your leger/trezor as "bank account", for every exchange you generate new account to not mix them.
Then chance is close to 0% of being frozen. (you just keep it away from exchange and is not in exchange that is all)
Problems may come when you start using that USDC as transaction money,checking account if AML/KYC system of some exchange (like paranoid Bitstamp detects unusual activity) they will froze you all crypto if some chain analis firm will flag your USDC. There are specialized companies making such analyzes.
EU with their AML6 is being paranoid with that so try avoid EU with almost anything that can be seen as suspicious.
Since USDC is from US there is less regulatory problems than having stable from EU.
