Base on my observation as an old time user here in the forum. Scam casino usually don’t invest much on license and promotion here and social that’s why they are easy to spot now compared before that most of the casino even trusted don’t prioritize license since most of the games being offered way back then was just a probably fair game like dice. But now even newbie players can easily spot them and just go to the trusted casino which always active in promotion here.
Plus when you have places doing millions of dollars worth of promotions, it is a lot easier to see who is a scam, which scammer would spend millions when they know that they can't just get that back, or they can simply just take whatever they can normally and do not worry about the rest?
I understand that it is not going to be easy, but it is going to be pretty easy for many people who are veterans, only hard for the newbies. I haven't been scammed by a single casino so far, not because I am smart or anything, I am probably not matter than any of you, but I have been here and it is so clear, and I guarantee you if people spend time here, all of them will learn to avoid scams.
If one of the reasons why it is easy to detect fraudulent casinos is that, believe it or not, sometimes there are casinos that invest in advertising even in signature campaigns and end up doing the bears very badly, this is something that has recently it happened here on the forum, and it ended up being a big problem, the things that some people do to take money from others have no limit, they can sometimes be able to promote even signature cams and do great marketing, and then go out with actions that make him think, that is, while they tell lies, some enter and play, deposit, and the bad thing is when he begins to withdraw that he does not allow them, and from then on everything begins.
It depends on the reputation of the casino in question, I have seen in the past casinos with good reputations that do not allow you to withdraw those kind of profits and you need to make a deposit, as it goes against their policies to do something like this, however if the casino in question does not really have a good reputation then it is possible they are trying to scam you or at least to not pay you what you are owed, so if I were you I will probably try to talk to their customer support and see if we can resolve this.
I have had many times interaction with casinos of that style, that you play and when you make a profit, you contact support and they usually say that they have to make the minimum amount plus the wager, and if those conditions are met, I was able to withdraw, however , when all those conditions that are not so easy are fulfilled, it could be said that they do not allow you to make the withdrawal, and the reason is that finally they say that a deposit must be made to be able to withdraw, and when they say that, it is sure that it is a scam, it is for this reason that when playing in an unknown casino you should be very careful, I would advise you to go to the forum and check if there is an Ann thread, if not, be very careful.
