yes but harder to move 10M in cash around from country to country.

I'm assuming I'm purchasing/selling a lot of MtG/Funko here in this example.

There’s a large industry for cleaning cash which then makes moving a clean 10M or even 10B in clean cash nearly trivial.

10M might not be as noticeable but crypto being nominally in a country on its own isn’t that useful as you still want to be able to spend it at the end of the day.
