Am not sure what he is trying to accomplish, but I know something about it seems fishy, i think he is trying to comb for personal info that he might use in a nefarious manner. There is a prior post from someone else on this thread addressing him as scammer. His reply when i ask was the individual's wallet was milked few days before their trade was suppose to occur and the poster blamed him for it.
Anyway, figured i should make a post about it, in case others are getting such request. I don't think it's a great idea to indulge this guys. scammers come up with different means on a daily basis to separate you from your hard earned money. So again be careful.
He is well known scammer. Just stay away.
