Didn't try this casino yet but one thing for sure if they are didn't ask some KYC then they will have may customer will play with them cause some gamblers always thinking that they can hide their identity if they still anonymous. . But there are some casino ask KYC in withdraw cause they found out that you are doing something against their rules and regulations and that's the reason they are asking some KYC in withdrawal.
Many of the casinos offer that no KYC thing these days but only when they don't have enough players or the players won't win a lot of money at their sites. As soon a player starts winning money in $1000 or more then they will change their policies and add that KYC thing in their terms and conditions.
The KYC is a norm now and the established casinos and exchanges will continue to ask for KYC whenever they need it but a new setup often uses terms like No-KYC to convince users that you're not going to be asked for KYC details even in future. But, they can change their policies anytime and no one can stop them or do anything against them.
I believe the KYC enabled casinos aren't bad at all because they're asking for KYC but surely one would prefer a non-KYC casino if he/she thinks a lot about his/her privacy.
