Is it possible for a casino to go bankrupt because a player gets a very big win?
I think maybe that's hard to happen if we look at casinos that are already big and well known. But suppose there is a new casino, and there are some players who are very good at playing, so they can win continuously, can the casino go bankrupt? or do they already have an algorithm or a way so players can't keep winning?
Yes, they can go bankrupt, especially for small casinos that only have small bankrolls.
But the way they closed the shop isn't because of one or two jackpot wins, but because there are some periods when a casino experience losses on average.
In this "red" period, users winning aren't getting paid so -> bad reputation -> no deposit because the casino is marked as a scam -> closed shop.
For big casinos, this kind of risk is small since their bankroll will cover any "red" period and replenish on the "green" period.
