Certainly not. As I keep telling people here, cryptos are property, not currency. Why should governments be in the business of telling people what type of property they can and can't own?
A coin is nothing but a couple of large numbers that are easy to multiply together but very difficult to factor...that's it. If the people of earth want to assign large fiat currency values to complicated key-pairs, then why shouldn't they have the right to do that?
Of course crypto-traders need government...like we need libraries and schools and police and all that, just like everyone else, right?
