Note that the official website of the project says that advertisers get real sales by spending $ 0 on marketing! How is that even possible? Some sort of action?
There is no exact information on this issue, I can only assume that some kind of cumulative bonus system will be introduced on the platform, thus, having accumulated a certain number of points, you will be able to order advertising for free.
In this case, there may be several versions, the affiliate program may be integrated into the platform, for the purchase of the person invited by you, you will receive points or credits.
