I'm not pro or con (I'm actually cozy with the idea of using BTC to buy stuff), but you might want to go back up and re-read the part where all forms of crypto become illegal - save for whatever is blessed, taxable, and trackable by the Fed.

You can still use the stuff for purchases... but if you get caught, the consequence is liable to hurt. If they can track/control your money fully, it wouldn't take much to ML your spending habits, find anomalies in those habits, and then come knocking with a warrant to inspect every electronic device you own in a search for outlaw crypto (and they may not even have to come to your door to do it).

Seriously, the permutations are, let's say, frightening as fuck, unless we get in some specifically enumerated digital rights, and ASAP.
