Then it's NOT impossible since exchange can give out identity for a certain circumstances. LOL. You just contradict your own statement. The OP didn't indicate the reason why he wants to get the identity of wallet owner that's why I answer it general which is possible through my method considering he is tracking his funds that recently hacked/scam. 
I didn't mean your post is wrong, nor did I contradict myself. If Op was recently hacked or scammed, he can't get an useful information on the hackers address from an exchange, as his stolen funds is nothing near a high profile crime, see the example I gave initially. I used impossible, rather than improbable to dissuade OP and other newbies who think it's possible to recover their funds, but go on to fall for a second scam in the process of recovery.
