In terms of fees, how much would you pay in a process like this?
Are we talking about 2-3% or more? Or less...?
As users, we want to pay the fee as little as possible. It is up to the exchanger to optimize it so that the users remain satisfied, and at the same time that the business brings them enough profit.
The swap of one order in several different currencies should not additionally affect the fee, unless one of the coins is Monero, where the fee is lowered to 0.5%. In the end, the input amount is always the same.
