Of course, if a player makes bets that amount to thousands and dollars, then it is probably not enough to simply read the ToS. In this case, it is probably worth involving a lawyer. But only one who has experience working in the gambling industry and knows many of the intricacies of regulation in these matters. But ordinary players still, of course, read and try to understand the nuances of the casino rules themselves, and this usually happens after some critically important event in the casino client's gaming history. And everything is limited to simple correspondence with the casino support, and in most cases the decision is not in favor of the client of this service.
From all this, in order to avoid many problems, people who consider themselves whales, before making any deposit, should contact support and say that they are players who like to bet a lot of money, and that they do not want to have problems when withdrawing, because I think that support will tell you how to do it, what type of KYC you can do, and in the end that is a support that will remain for the player in case of any inconvenience , well at least I would do it that way.
