no, you sir are unhelpful troll, he was scammed, sure - it is a bad idea to use paypal for anything more than $10 ebay purchase, but this is no more than lack of knowledge

if he will ever do that again that would be stupid

as for OP - if you are dealing with a pro chances for finding him are very small, 1st make list and print screens of anything you have - address, email, phone number etc. etc. then google a lot

there is hardly any way to trace bitcoins, all he needs to do is to send those to himself couple times
