Its actually simple. Once he tries to get fiat, you investigate and make him prove source of income and fiat to bitcoin trail to support it. If he can't verify source of income, confiscate the cash.
Yea if he sells it all on an exchange but what idiot would do that. If it was me I'd be selling for cash using summat like loacalbitcoins/friends and there going to be more ways of hiding it, that I can't think of right now. It's not as simple as u think.
