@Best_Change, speaking about the reviews

I was not able to look in details when I visited the site earlier but then I noticed there are no negative (red) reviews for any exchange.
This is tricky. A part of Neuromarketing. Nothing wrong with Neuromarketing but your approach is misleading. You are giving the users a look that there are all positive about the exchanges you list.
An internet user who do not have time to look at every details for different sites, do not know how different exchange sites function in details, mostly they are your visitor. They see everything good about all the site you listed. It does not always raise in mind that why there are no negative for the sites listed, they check for the best exchange rate. They see reviews but easily miss the part of no negative review, eye balls are are always on the numbers of positive reviews. They do not see any negative for the selected exchange too because eye balls are always in the positive ones. They make the exchange.
So, even you are saying this is not the best UX but this is obviously misleading approach.
I do not think loyal visitors which you think regular apply for site like yours. In a site like this (listing sites) internet users do not spend much time. They know the site exists, visit, find the service, leave the site. Almost all the users in your site do not really need to know how the site functions entirely. They only see the first page and the data left on the table. It is important that you present your data correctly.
I am not blaming you for anything. A service always can not serve everyone as the client expects. Thing can go wrong sometimes which is absolutely fine when there is intention to make it correct. I think you really need to improve this feedback part and be real. Right now this is not a real feedback system, not from the look of it.
