Which payment aggregator is better for a game project and do I need to pay taxes (how)?

Question

Payment systems

Good day!
I asked myself the question of connecting a payment aggregator for both the CIS contingent and WorldWide.
It is necessary:
​​1. Support for the maximum number of payment systems
2. API customization
3. Support for game projects
I looked at similar topics here, a topic on Habré , but, unfortunately, I did not find a sensible answer.
Actually, the essence:
1. Which payment aggregator is best suited for specific purposes? (I noticed that many game projects switched to GameMoney , but I did not find any sensible information about the aggregator)
2. Is it possible to use several payment aggregators by customizing the payment page via API? (and would that be the best option?)
3. How to pay taxes? (I have repeatedly heard that aggregators pay taxes themselves. On Habré, I came across a post that you also have to pay taxes from the aggregator commission, i.e. having an income of 100 rubles and an aggregator commission of 5%, withdrawing money to a current account , you have to pay tax from 105r.)

Answer 1

I know that many gamers use unitpay.ru. Well, not gamers either ;-)
Is it possible to connect several aggregators? Of course, many people do this, and even the big ones even more so. Plus, if one aggregator suddenly fails, the user will be able to pay through another. Well, plus the commission for different types of payments can be different. But on taxes - it would be necessary to confer with the bukh.
