You need to clarify which government you mean. Because some countries have accepted and legalized bitcoin as payment or investment. But I know there are still many countries that do not legalize or even ban bitcoin. most of them do that because they want to protect their citizens.they think that Bitcoin is a very high risk investment, and I can't blame them for that. I am sure that as soon as this method is found, the government will start saying that crypto currencies are legal, that is very good. for people to deal with crypto currencies and pay taxes. Because if the government legalizes bitcoin, people are easier to make payments and make other transactions .
