Yeah, that’s probably it. The problem is, most casinos get their license from Curacao and it’s been criticized a lot for having weak regulations when it comes to player protection. That’s likely why many casinos choose it, easier to get away with stuff. Now it makes sense, lol. So if we don’t want to get cheated, the best move is to stick with the most reputable casinos only.
On my mind I always personally though Curacao licenses were just something you pay to run your casino worldwide and that's it. Do they really check their licensed casinos and cancel their licenses or fine them if they find any wrongdoing? I would say the biggest win is for sure the Curacao government that makes money and don't have to do anything.
I will always prefer casinos that are as transparent as possible, and provably fair systems is a big safeguard for customers. For example, how do we know if the coin flip we just did wasn't tampered to make us lose?
