How to give money to users?

Question

Payment systems

There is a website for the game. Everyone is playing there, moving chips, changing artifacts and all that. But here we decided to add the possibility of withdrawing earned funds. Those. convert game currency to real. However, users are scattered all over the world. Someone in Africa, someone in America, and someone else somewhere. How do they get paid? Robokassa - payment acceptance interface. Is there anything for donations?
PS I would like PayPal, WebMoney, plastic, etc. Some kind of common interface, so as not to start wallets everywhere.
UPD. New info. It turns out that payments will need to be made literally 15 pieces per month for a total amount - less than $ 3,000. Those. It turns out that users can leave applications, and we ourselves will send them manually. But still the question remains - how? You cannot withdraw funds to foreign cards (you can, but there are literally 15 countries). Is cash only Western Union? What other ways are there other than registering a company outside the Russian Federation?
