If the government issues official permits for Bitcoin, that will be the main policy they will make. But I feel that it is impossible to happen right now, because there are still countries that prohibit Bitcoin from entering.
Government should not be allowed to mingle in crypto affairs.. Governments always wants to have control over everything that is happening in their respective countries. I believe most people don't understand how crypto currencies work. The authorities are really sacred about crypto but they wish they could do something about how decentralized blockchain technology is.
