you should considering doing a vouch from a long standing, trusted member. Will defo help you out in terms of sales going forward, considering your a new member
vouch copy does not mean shit when trading gc , any scammer can give a legit 50$ gf , get the vouch and scam 10 members. even escrow is not really safe dealing with gc, he could still deliver the gc, and once he gets the funds he can charge back his cc and say it was stolen, this ofcourse if the gf was not already stolen.
long story short, trading gc is extermly risky and i'd simply say that 90% of gc sellers are scammers.
