This approach from the point of view of marending is the right one. "Buyers have many advantages on WeBuy, but there is nothing to buy without a Seller. That is why sellers invited to the platform will receive the automatic equivalent of joining $ 500, which will be spent on advertising on the WeBuy platform. A grant will be received through trusted stores." The question remains in converting from Fiat and about back to Fiat. Also, I see difficulties in determining the value of the goods in an equivalent amount, for example, to the dollar.
