to any person on any day in one or more transactions). "

As I read that, bitcoin falls under 1 and not 3/4
So it is still under MSB regulations but not all those defiinitions are necessarily the same rules, as one would expect there are different regulations for a Check casher than the U.S. Postal Service.
