We should all be able to use cryptocurrency within the open, free market.
It is my opiniom that cryptocurrency should never be used as a form of currency issued by the federal government of the United States of America as a standard because it is unconstitutional.

To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures
Correct. As is Federal Reserve fiat money. Under the enumerated powers clause only Congress has the power to coin money. The central government/Congress are only given 17 powers, everything else belongs to the States and the People.
17 powers - you don't say?
