I am having a bit of a hard time trying to grasp what you are saying, but if you are referring to the problems that might happen if cryptos are to be regulated then you shouldn't....unless you purely depend on custodial wallets where your cryptos are being stored.
Surely if cryptos get regulated which is likely to get taxed, then slowly people would go to the point where personal or p2p transaction would be the best thing to do when trading or selling their coins to avoid these.
