You don't deposit using FIAT. Only crypto deposits which you bought through p2p channels in person using cash. Buying your crypto sending cash by mail is another option but it's more expensive and less safe.
Seems to me you are afraid of reporting.
The solution is simple. Buy your crypto p2p for cash and store it on a hardware wallet. If your aim is trading use a broker without kyc or use an account verified by someone else.
