Question

Payment systems

There is an online game.
At the initial stage, we want to connect a payment aggregator to physical. face.
Sole proprietorship and LLC were not registered.
Commissions are high, but this is not a problem.
What are the risks associated with such a connection?
Can't it be that the amount on the account reaches $1000 and we simply won't withdraw this money?
There is no contract, no one has been formalized, and you can’t prove anything - is that so?

Answer 3

Use the Yandex form - it allows you to automate the acceptance of payments, accept on an identified wallet, and everything will be fine)
