I suspect that volatility may be a feature to money launders - not as ransomware transmissions or anything like that but justifying balance transfers. Not saying that was even an intention as opposed to ideology but to paraphrase cyberpunk the street finds its own uses. The fact there are innocent users is what makes the conspiratorial useful.

This is all read and theoretical - I certainly don't have any practical experience with either combatting or committing money laundering.

Anyway fine art and wines are infamous as pretextual transfer vehicles because the values are often so subjective - bitcoin swinginess serves the same purpose, especially if the hypothetical enterprises control enough to manipulate the market. Big assumptions of course that such a thing exists but it highlights who it could be useful to (intelligence agencies and organized crime - which are arguably largely the same thing to the host country - both break the law in pursuit of their agenda).

Anyway that form of laundering involves buy something at a lower/normal price and selling high. The selling high can be from having a contact buy it for higher with your dirty money. Of course open sales would be preferrable - not only because deals only between connections are obvious but some bonus profit. If someone not involved outbids or provides enough of a margin to be worth backing off all the better - you can move the dirty money another day.

If one needs to funnel clean into dirty do it in reverse order essentially.
