I Understand, but some users just want to make money, they don't care for ads and never attention to ads, and our main job at ptc.click is to both deliver ads and pay users not just paying users, also this way we only keep loyal, good and high-quality users who really have attention to ads, which make good conversion rate to advertisers
yet there is another problem, we must have a good balance between deposits and withdrawals, how we can pay 2000 users each 2$ when deposits don't fit it? many sites pay far lesser than us on each click, their first withdrawal is 2$ but the next is 4$ up to 10$! also they don't pay 100% direct refs without profile upgrade, they put a limit on direct referrals! but we don't, we want our users to really take good profit when they promote their aff links without any prepayment because they deserve it.
hence minimum 3$ is a good cause for users to put more time and interaction on ads, also users more tend to promote their links to reach the withdrawal limit sooner,
Furthermore please if you have a different question like this one ask it as a new thread, not inside another thread, because a user struggles to find our conversation with the same question as yours.
