Now this may discourage the whales from gambling there and the casino owners may be giving up the huge profits they could get out of whales, but at least on the early stages of their development a casino like that should worry much more about not going bankrupt than the profits they can make.
this is business and that is what they wanted to gain.
but if whales wanted to bet high? they can use multiple site to bet at the same time with the amount they wanted to try winning.
Of course, a responsible businessman will definitely read all the risks associated with even the very unlikely series of big wins that whales can make. And this is how, I believe, the responsible devs and casino administration should calculate the size of the maximum bets. But of course, I admit that not everyone can accurately determine how to call it, apparently about the "margin of safety" of the casino in case of catastrophic luck of one of the whales (of course, I don't mean any fraudulent schemes, but I'm still talking about unlikely events in provable fairness algorithms).
But as the funding of the casino itself grows from profits or additional income from investments, sponsorships and similar additional income, it is obvious that the size of the maximum bets can be increased. Of course, subject to the stable and profitable operation of the casino itself for a long time.
