If you increase the % compared to what was highlighted, it is definitely considered a hidden commission, although there are worse names for such behaviour.

Thank you for your feedback. I want to clarify that all details regarding how our fixed rate works, as well as fees, are transparently described in our policies available on our website. You can find the full explanation here: Privacy Policy.
Regarding the fixed rate, here's how it operates:
When you choose a fixed rate, you receive the amount indicated at the time of transaction initiation. You only pay the selected fixed percentage + exchange fee and network fee. If the market rate changes by more than the selected percentage before receiving the required number of confirmations on the blockchain, you will be prompted to either proceed with the exchange at a floating rate or request a refund.
We are committed to full transparency and ensuring that users know exactly what they are paying for. If there is anything else you'd like us to clarify, feel free to ask.
