eXch is not really a legitimate company, I would not expect them to pay out any of these "rewards".
Yes, they process (most) exchanges without scamming, but they steal through their affiliate program. It's well known that they don't count even 1/5 of the transactions that affiliates send.
THAT is the reason dark dot fail, the darknet bible, and others stop linking to their affiliate program, and start either scamming or processing transactions themselves.
Everyone "helping" this company, hoping for money, is a huge sucker. And you're helping a "company" that steals from people who send them traffic.
Have you created an account only to say that? Without proof, there is no way anyone will take your comment seriously. You make an accusation and you should support it, otherwise the message is just 4 lines of spam.
