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.

A market with 'money' is controlled by the government.
A market with cryptos and barter, is controlled by the people.
