Can you be honest and explain exactly why you are posting in a negative manner about eXch? They have no scam allegations against them and highly respected but you have nothing positive to say about them.
It was explained to him several times and in several ways how the swap on the eXch exchange works and the dependence on demand and supply, but somehow he refuses to understand. I don't think that he doesn't have the capacity to understand everything that was presented, I'd rather say that it's just plain trolling
