I have a web site (on php) and I want let users to earn money on it, one user will sell information to another (buyer will add funds to his account (bill on website) before or to pay with paypal at once). The seller will get money for that, but he have to get money on his personal billing on website and if the seller got over 50$ then he can transfer money to his paypal account. I guess the right decision is to make one PayPal account for website and keep user's money there, and if user got enough money for transfer I will pay him money from my account. Website is already using paypal.
Is it right decision? Or may be there are any other paypal functionality for this case? Thank you!
