I think this kind of game have a very small chance of winning. And I don't think that this is really secured because they don't need KYC so in short they are no concern whatever what happened on your investment. I hope they can improve their features specially in terms of security.
In my opinion, any casino that does not care about the customer which to me is defined by KYC is a casino that I can't trust. And why would anyone opt for these when there're plenty more which do KYC
