Money laundering systems aren’t something that run continuously like their daily operations. Instead, they are triggered by specific red flags or events based on the casino’s internal controls.
What I know for sure is that we don’t really know what guidelines they’re following as advised by the regulating agency. But you might be right, they could be using a centralized system.
Because of this centralized nature, criminals or, more specifically, money launderers, can be caught more easily if they’re using crypto casinos for laundering. That’s why casinos have to be very proactive in monitoring activities to do their job effectively. A single mistake could be incredibly costly for them, as they could be accused of enabling such illegal activities.
And it's going to be a long-term problem for them. It's either the government will milk them over and over again or they will be closed down and even if they change the name of the online casino, it could still be a problem for them in the future as they will be branded as running away from their mandate.
It will be difficult for them to create a reputation and any business won't like that since there will be fewer customers.
I do believe every reputable crypto casino is being strict with this rule as it could cost them everything they worked for and monitoring every possible red flag is a job they must do to avoid that even if they will need to pay a hefty price for the security.
