This is actually a very interesting question for me. Is it true that you can be banned from an online casino like Stake for the only reason that you are winning too much?
I know it used to be a thing for some land based casinos in the past, but I don't think reputable online casinos of the level of Stake are practicing it these days. In fact, I'm pretty sure that all top online casinos don't do that.
I don't think you can really ban players for that as they do nothing wrong in fact.
They will probably just limit the players so they can only bet a low amount on the sports they always bet on. I got limited on a fiat only casino one time because I won like a bet of 100€ lol.
I don't think they would do that either. First off, you will never read in ToS of any reputable gambling site that winning too much results in some kind of limiting your bet amount. Secondly, you can bet a low amount many times and voila, you are betting big again, right?
That fiat based casino you were limited on for winning just €100 wasn't an example of a good casino, if you ask me.
In the sport book it can happen in any casino because they buy the odds from another provider but in any trustworthy casino you will never have your amount limited if you win big in slots,at least I have not heard stories of such happenings in casinos we all love like Stake for example.Every time I check the lucky and big wins below the slot that I am playing I see an insanely huge amount of money won and the usernames of those people who have won them are still active there,meaning they did not get limited.
