Lets channel our inner detective and look into this thoroughly. Find a casino with a valid license before playing there. Read up on the experiences of other customers and stay away from any sites where withdrawal troubles have been mentioned. Researching the fine print of their agreement is tedious, but it's essential.
But seriously, dont let the rush of quick cash make you sloppy. The biggest weapon you have against con artists is your own common sense. Also, keep in mind that anything that seems too good to be true, usually is.
Even casino like 1xbit has a valid license. They also have a lot of sister company that has valid license too since Curacao license is very to easy to acquire if you have money which is not a problem for a scammer company.
If you really want to channel your inner detective then you should focus your research on the trust history and reputation of the casino here in the forum since every issue that they encounter is documented here publicly and a single known scam will surely reflected with their trust score here in the forum. Only trust casino that has a good reputation here in the forum since most of them maintain a good communication here for a better forum customer relation.
