Who should pay the deposit / withdrawal commission on the site, the site or the user?

Question

Payment systems

Who should take the commission?
Depositing money to the site, PayPal takes 4.4% , withdrawing funds (international transaction), another + 4.4% comes out . And that 8.8% tax. Out of $1,000, $88 goes to commission only. It's like an example, something similar with any payment system.
Example: a user enters $100 to the site, receives a bonus from the site 10. The user already has $110. The alignment is such that the site takes over the tax. Then, in addition to the bonus, he pays +% commission. The user withdraws funds from the site, and again the same situation, the commission for the payment +% tax of the site itself, for services. Who should pay the tax?
If all expenses fall on the site, it comes out of everything written above that - the user entered the money, let's say back and forth, changed his mind or something. It was $110, we take the site's commission for services, say 10%. He already has $99 left, now he needs to determine who pays the commission, both in the first case and when withdrawing. If the site in both cases, then at 10% for the site, the site incurs losses, Paypal 8.8%, and pay for work, hosting, etc. ... 2.2% is extremely small. If the site pays a commission on input + output, then at the output when the user withdraws money, the commission should be at least 17%.
The option when the user pays commissions, he will have to pay 104.40 (4.4%) to transfer the amount of $ 100 to the site, the same thing when withdrawing, he will need more. In this scenario, the site can safely take 10%, because all transfer fees are paid by the user.
The question is, should the site, as a provider of services, take over the commission? Or let the user pay? Or the site, will pay 50% of the commission? In both cases, input and output? Or just on exit? How is it better?

Answer 1

Don't confuse taxes and fees.
A commission is a fee for a banking transaction. It needs to be paid.
And taxes are taxes on operating profits that are paid to the state depending on your activities.
As for "who is better" - if you monetize the site:
2) You must know what percentage to take for yourself so as not to work at a loss
1) You need to monetize in such a way that the user is ready to spend money for your services. If you have the simplest operations, and you charge 10% for them - who needs it?
If you have the simplest operations, and then the user will then sit and think how much and where else I should pay, what the commissions are, how to calculate them - 90% will immediately say yes it’s all gone, it’s better that I stand in line with grannies.
In general, your question is NOT of a technical nature, but exclusively financial
