You know what I hate? Those offers where you have to show your proof of purchase to get a bonus or a cashback. You take a photo of the receipt, fill in the form and after 4 weeks they let you know they couldn't read the invoice number or something like that. Sometimes I think they do that on purpose. Anyway. Would GATCOIN also be able to streamline that process?
In my country, there is not a system you mentioned right now or in the past.
And I don't think that a project like gatcoin who just want to make more of a practical system, won't go for it.
