But not all problems at a casino will be found unless the gambler has gambled at that casino, so gamblers will review the casino they choose to gamble at and they generally don't know the problems at all casinos unless they check in detail at each casino to ensure the casino system is fair and does not complicate the withdrawal process.
A wise person is the one who learn from other people's experiences and mistakes. So, if many users say that they had a bad experience with a certain casino or that it is a scam (they need to be trusted users or if they present undeniable proofs) then you don't have to test the casino yourself and repeat their mistake.
In case you did a research and didn't find any review you can trust and you don't have any other option but to try the casino yourself, then at least do it with a small amount of money.
You can only learn a little from the mistakes of others but until you experience it yourself you will never understand the reality. When you use different casino sites you will know from your own satisfaction which casino site is best for you. And when you personally keep making various mistakes, you will gain a lot of knowledge from them which will help your conscience to avoid them later. no person can ever suggest you which casino site is the best. Because only you can understand better which one will be best for you according to your needs.
