I would love to meet the same kind of law help from my compatriot,because of the law base for crypto in my country (Serbia) still stays unclear for many users and who knows what is allowed here and what is not. I do not wish to be a criminal, but I actually didn't meet a person who knows all details here.
Ah damn , I mean Im knowledgeable in EU and UK Law, it would depend where your said coins have disappeared? I could help draft up a letter if need be. I wouldnt have a clue about Serbian law tho
