Firstly, did you ask for help/information from strangers on another forum?
if yes, then why you even bother asking us for opinions???
you already decided to seek help from strangers! then just do it!
if no, then i assume this guy approached you, and offered info on HCMC.
you did not provide enough information on this particular guy.
how did you know each other?
if you don't know him at all, just a random stranger on the net...
then screw it, IT"S DEFINITELY A SCAM.
but if you know him from an anonymous forum...
then you have to judge how well you know this guy.
