Different countries, different regulations, I don't know how far that goes. But if your friend just wants to avoid being tracked on his behalf, shouldn't that be possible by using your identity to register an account on a legal CEX there, then liquidating directly through your bank account?
Maybe ask someone trusted but non-family related to received the funds and use him as proxy for the business and gift the money for the house repair in exchange for some fees.
I know some people are trustworthy but individuals can change. A family member might become greedy or jealous and with the money. And you cannot report to law enforcement agencies because you committed an offence. Money can change people and I have seen people misbehave because of money. My best advice is to play safe, obey the rules of the aid, convert the money to Bitcoin and hodl. Those expenses can wait after all they are not health health related or other pressing issues. Keeping Bitcoin is another good investment.
