OP, if what you wrote about Bons.com is true, then they are not ready for the business yet, or should I say that they are in for ripping off unsuspecting people. I just started to see the casino's signature recently on the forum but I've not tried them and I do not think I can ever try them judging by what you said. If I read you correctly, you mean $800 minimum to withdraw via ETH, and 10% will be deducted from your money whenever you withdraw? These are enough reasons to dissuade people from using them. They could be successful in attracting customers due to their affiliate programs but they can't make such customers stay due to these ridiculous conditions in a more competitive gambling industry.
But for the Trustpilot review, I do not trust it, I don't even use it, and that website has never been a serious place to gain the best info if you are smart. Also, about the KYC, I think that's the standard for some companies these days and you can't blame them for that especially if they are truly regulated and the regulator demands such from them.
Exchanges ask for that often and people gladly oblige them.
