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.
for the value I think bitcoin has been like this is quite profitable for some circles, whether the investors or trade, because for the miners will not have a big effect, but the need to set up the deficiencies and weaknesses of bitcoin can be overcome so some actions we do not want will occur, the taxation system may be applied but reasonably.
