Re: Receiving BTC through wallet pear to pear can put you into problem.
Is P2P too difficult for your friend to trade his Bitcoin himself?
Ask about the source of the Bitcoin, if he purchased it himself then he must have exchange to trade for himself. If the source of his Bitcoin is infested, you automatically become an accomplice, it's no longer ignorance to you.
