What are you talking about? There are plenty of crypto gambling sites that are just as reliable as Roobet and don't require any form of KYC whatsoever like Crypto.Games, Stake, Bitcasino etc.
You don't seems to understand my point clearly because i also mentioned that finding a good legit casino is main point of concern and i also known about the casinos you are talking about.Roobet is among one of them but as i am comfortable with level 1 kyc it's not a big problem for me but who wants complete anonymity can shift to others like stake so this was what i want to say.The new gamblers might go to some fake casino in hope it doesn't have any obligations but can loose funds so he must check for legit casino at first case.
