I completely agree that reading reviews and checking the reliability of the casino is crucial, especially if it is a new site that you are not familiar with. As you mentioned, unfortunately there are unscrupulous operators who may try to scam players, so it is important to be vigilant.
I will far leave a casino like that if it continues then there is a high possibility of losing or being cheated by someone under the guise of being an operator, if it is like that then the future will be much worse and there will even be many victims resulting from fraud by operators or people who are not be moral, it is better to play a casino that already has a big name because there are many big casinos on this forum that provide comfort or protect the assets of the players in it because that is much more important than having to cheat the players which will ultimately bankrupt the casino in the future because cases created by the operators who work in it..
The desire of many to have a better casino or to put a casino in a good position is a lot, however when we do not try to review many things, reviews, and some Threads of those casinos, something does not catch my attention. So, I always look for casinos that are reliable, that I put my money in and there is no problem after withdrawing it, it is a fact that the most reliable casinos are like that, the ones that have a very good Reputation, the rest are not bad but they have many things that can slow down your withdrawals, the KYC requirements are now very demanding , especially in the casinos that are newer, when it should be the opposite, but seeing this problem I continue to be careful with the casinos that I already know.
My way of seeing that casinos are good is that they run excellent campaigns, that gives me confidence and that is enough for me to trust, it doesn't hurt to do your Own Research.
