Not all gambling sites are deceptive, and not all casinos can manipulate games to make their customers lose.
Defeat in gambling is something that is certain to happen, so as a gambler, you must be able to accept any losses you experience, if you don't want to lose, don't gamble.
On this forum there are lots of big, trusted casinos and you can use one of them to get comfortable and be able to play or bet without fear of manipulation.
Unless you play in a scam casino like 1Xbit maybe you will be scammed and lose a lot of money.
It is unethical to say that gambling sites are cheating but only because you lose when you play.
We can see that there are lots of gambling sites like that, but for gamblers who understand and can accept defeat, they will not say that the casino has deceived them, and that winning at gambling depends on your own luck.
It's better to gamble for fun and forget about losing or quit when you lose then it's much better than continuing but losing and blaming the casino.
