I'm a little bit skeptic about this, It seems like reviews started too early (for a new service) and also, the users who have commented in your TrustPilot page only have a review there so this makes me wonder... Is the process manual by the way? or you're using some kind of API to make things automatic?
Though this will be a good development for crypto because gradually it be become more accepted but I also support your view about these site because to me it is really not clear how it will work .
