It is possible that we may have some good companies which are genuine to great extent and other where it is rigged and winning of the company owners are higher than yours or the participants. Also at the end it is a business for them and they want to earn money.
Correct but there are casinos that are long standing in the community and if you are going to play on some casino then you should visit those only. Not those new casinos which pop up every now and then - you never know which one was built for being scam.
Those who are making up stories with false claims about casinos will keep doing so only because they lost money there because they were greedy. If you cant control your greed then you will end up losing all your money. That does not mean the casino owner is a scammer.
People are more interested in self-gains > when they dont get that they start complaining about the same thing that they put their trust on in the first place.
