so my question is
can the casino control the wins and losses of its users?
Of course you can, but only in casinos that don't treat their customers fairly. Large casinos that have a good reputation with millions of customers will definitely avoid this behavior for their customers, but not casinos that only want money from their customers. I've seen videos about how casinos cheat their customers by controlling each user's winnings, but maybe not with well-known, reputable casinos like the ones on this forum.
The casino in question is a casino that may not be regulated by any party. They operate illegally with only the trust of a few customers and not much capital support, but along the way they don't really treat their customers fairly.
Lots of shady casino act like that this why we must choose the casino we play. Since if their fairness is questionable then provably that there's instances that they provably manipulate the results since scam always want the favor goes to them and they don't want their costumers to win.
So more best for people is to choose to regulated and trusted casino since those manipulation of result they think provably not going to happen in legit casinos. That's why sometimes I doubt to try new casino especially those obvious ones who present shitty ann thread here, I'm skeptical on everything especially if they didn't impress me in first glance.
