I just checked trustpilot and to my surprise, they score extremely high over there: 4.7/5. Never seen a casino so high as most of the times, you will have more complaints than positive reviews on there.
Trustpilot is actually Distrustpilot based on my observations because half or more of their reviews aren't trustworthy at all. For example, a site like 1xbit has 3.8/5 stars which literally says everything by itself.
Proper feedback for crypto sites can be found only in dedicated sites like Bitcointalk etc.
Which makes it quite interesting as far as casinos go, normally casinos end up getting low ranks there because most of them do end up with a result that is far below what they deserve, since people who lose money (and I mean legibly, gamble and lose) go take their anger our on trustpilot by telling lies about the casino and trustpilot does nothing to stop that. You ended up losing a couple grand here?
You can go to trustpilot and give 1 star and say this is a rigged place and they have no way to stop you from doing that, it is a horrible website for reviews and I would never check that website for any place. But roobet is ranked high even there, which is unheard of, and that is an incredible achievement for them without a doubt.
