i think its okay if the government give the tax to the bitcoin holder and the investor, with one condition, bitcoin can be used freedom in that country and 100% legal, so we can use the bitcoin as the payment system in that coountry
Bitcoin transactions are peer to peer, so the government must legalize to get taxes. Although prohibited, transactions continue but are illegal and the government does not get taxes. Regarding the negative side of bitcoin transactions, the government must monitor to minimize the impact.
