So to get cashback you have to buy and hold Binance's token, and your cashback is paid in more of Binance's token? Seems like a pretty good way of artificially pumping the price of their token more than anything else. They don't actually have to pay out anything in cashback here, because if a users wants to convert their cashback to BTC or fiat it will be other users they are selling their BNB to, not Binance.
Yeah, Binance card teem is sly asses, now they need nothing to do to promote and pump their token. The progress of the token will depend only from popularity of the card and surly it is going to be in demand, because of - who doesn't want a cashback?!
