Nobody is going to pay for your cards just to earn in the future if someone uses their ref code. Emphasize on if. Good luck though.
Thank you for your advice.
However, a review written in exchange for money cannot be inherently honest, as it will have been purchased. We believe this to be unacceptable. Furthermore, no one would pay for a negative review of themselves. It is important for users to test and write reviews themselves in order to ensure that they are truly honest.
You have misunderstood everything about the cards. You will earn as soon as your referral registers with your code, and you will receive payment immediately from your referral in the amount of the card cost.
