I think in this regard the first exchange in Turkey is setting its own code.
I've studied the campaign a little, first they all print the coins, then they promise to buy back from time to time. that is, there seems to be a way of appreciation. They are already earning coins without making a payment, they are giving them away. I have to buy all kinds.
It was enough to be a member of the stock exchange to buy coins. But you also deserve when you involve others through reference.
It was nice to offer subscribers for free, but I wish they hadn't done the campaign with reference too, here reference link dollars, be ready soon.
In short, win / win situation. Proceed with the registration
