One way is that, convert fiat to crypto and then to avoid being flagged with an ewallet, use crypto in deposits. But who knows if these lawmakers will also this but even they will, I don't think they'll have full control to it.
You can move your fund around and avoid letting banks knowing that your money is from cryptocurrency trade, investment and don't let centralized exchanges know that your cryptocurrency is from mixers or gambling.
Not all banks are against it, not all centralized exchanges consider gambling related fund is risky for them, but if you can spend some cents and time for moving your fund around, converting it between cryptocurrency and cash, before making any deposit to bank or any centralized platform for spending for anything, it's safer approach.
It is not feasible approach with many people from time and extra cost spents but privacy matters.
