Thank you for your review but I just have to say that nowhere on the site this is claimed?
In FAQ we wrote this:
"Why do I have to pay a fee?
    Paying a fee increases your privacy because you will not receive exactly the same amount you sent us
    And also for the service to improve and operate successfully we need to make a profit
    Our fees go from 0.80% to 3% the amount is chosen by you"


We never say that paying a higher fee ensures more privacy.
