Hello sir, I would assert that:

• A United States fiat crypto currency on a floating exchange would be in violation of U.S. Constitution Article 1 Section 8 "To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures;"

• The existence of Federal Reserve System is not unlawful, but the 'independent organization' authority of regulation of the FRN + the legislatures failure to mint sufficient constitutional money and force the FRN to peg to it (lawful money) instead of the other way around, is unlawful and in violation of the above part of Article 1 Section 8.

• There is a legal path of remedy open to have the lawful United States Dollar separated from the Federal Reserve Note, and bring back sound money to the land.

• The legislature can lawfully designate a 'foreign' cryptocurrency as legal tender.

• Any commodity backed crypto currency would be a good thing in the long term but would pose an enormous threat to the safety and well being of the American people in the short term.
