Many new casinos require KYC for withdrawing, there was a discussion about this, if there's such a rule then there should be KYC before deposits as well! Like this it looks like a trap, who made a deposit without knowing about this rule will be forced to do go through KYC or to gamble the deposit!
There is. I just tried signing up and the site is asking for my personal information. Name, phone number, address, date of birth, etc. You could of course enter the wrong information, but that might become troublesome down the road if they ask you to undergo proper KYC.
You need to clarify about your deposit promotions, you said the first deposit bonus up to 1.5 BTC but based on your sites it's wrote up to €/$300... €/$300 is 0.07-0.08 BTC not 1.5 BTC, did I miss something?
My guess is that this is was originally a fiat casino that has just recently adopted crypto. According to
Whois, they have been around since 2019. Everything on their homepage shows only fiat values in $ or €. If you visit the crypto part of their website >
