Just to add to this, he's most likely hacked as there's an inactivity gap of about a year and he's now started posting from proxies. Besides that I've seen Mandingo post before and his posts actually spoke of a smart person, rather than a retarded one who warns not to trade with others in a post on their threads.
I messaged this guy and offered a reasonable rate, Everything seemed to go well until he denied my offer of a middleman and said I will have to go first even if it's 50m, so this guy just seems to want a quick buck - BE CAREFUL
As @Wortel mentioned this account was likely hacked. I am very sorry for your loss @cicdealer. If @Mandingo wishes to return he will have to repay you.
