The digits are overwhelming and completely too good to be true. Though it's not impossible for a $200 per referral but for this kind of shitty exchange that even couldn't pay a professional web designer, it's totally BS.
Highly suggest better to stay away from amateur sites even the offer is lucrative as what you can imagine.
200 dollars is a very approximate price. Since the CNB coin is not yet traded. To understand how much you actually paid for referrals, you need to wait for the bidding to begin. In the meantime, it's just 2,000 CNB coins.
