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.
Asos.com has 3.7 rating on Trustpilot. I am ordering clothes from them since 2017 and I have never had any problem and it amazes me why their rating is so low, asos is also considered as one of the best e-commerce platform. But it doesn't amaze me that Roobet has so high scores, they are really a good casino and their marketing team does a good job.
Proper feedback for crypto sites can be found only in dedicated sites like Bitcointalk etc.
That's why scam accusation threads on this forum have instant reaction. Sportsbet.io, one of the most famous sportsbook company had negative trust at first because they refused to pay to one of their users but over time they understood the importance of trust here, returned and become one of the most trusted sportsbook in crypto world, we can tell the same about betcoin.ag too.
This forum matters a lot!
