The "right" regulations would be all the new rules that remove the anonymousy of btc transactions.
"Know your customer" policies and ID verifications would become mandatory for all online bitcoin wallet services and all exchange platforms.The harder for criminals to stay anonymous ,the better for the bitcoin community.I know that a lot of crypto supporters hate the KYC regulations,but there`s no other way to reduce the crimes and fraudulent activities with btc involved.
I'm not sure if I agree with this but it can't be solved by just motivating every user to be honest, after all. This is why governments should study and learn how bitcoin works first before making decisions.
