As i expected because those people wants to control crypto currency,they want the power to track it.They are feeling insecured because if crypto starts blooming then usd will face a lot of difficulties all over the world.They will lose their supremacy.That is why they are talking like that.Some of the officials are also declaring that crypto will vanish in next few months.May be there is some difficulties come if usa government convince other country to ban crypto.But at the end crypto will win for sure.Thanks for the post.@resteemed
