for a beginner maybe paying attention to reviews from other users can help. but for gamblers who have been around for a long time, I believe they will be more loyal to casinos that have been proven to pay their winnings.
some gamblers may have several accounts at different casinos. but I believe that gamblers tend to play at one casino that is considered good and comfortable. so for beginners who want to find a casino, please try some references. it won't be a problem when you only try to play with small funds for the purpose of gaining experience.
because every gambler has a different experience with the same casino. of course, all also relate to the character and desires of the gambler.
that's right and sometimes there are also beginners who don't pay attention to things like this they just search, register and immediately make a deposit to gamble. this is considered trivial or small but actually quite important to note, especially for beginners who are new to gambling and seem to be able to apply good habits by looking at reviews of new casinos they visit, and for those who have been gambling for a long time I think they also need to see this when they visit a new casino even though they will most likely stick with the casino that has paid their winnings as you said.
surely everyone who is familiar with gambling has accounts at various casinos including myself and maybe you too. if for the amount of the bet it depends on each person because the financial situation of each person is different, for beginners they can look for people who like to gamble and ask for a casino reference.
What usually catch their interest is the promotions given to them that's why they not tend to choose a casino which have good offers to their player. Seeking an information regarding on their reputation is less concern since usually they are blinded with fund and other offers to be given.
But for sure if they gather enough experience provably that they won't bother to much looking on promotions, rather they look how reputable the casino i and how they gonna process all necessary things including withdrawals and support matters since for sure this will be the one important thing they would look for.
