But the interesting question is actually whether the casino will hand over the money to the government when the account user who has the nominal does not provide the data to the casino, this is no provision, so it could be kept by the casino or given to the government, and this is difficult to determine because it questions what steps the casino might take.
Due to the fact that such action from the casino would put their license at risk I.e if they decide to go ahead and keep the money for themselves after confirming that it was indeed from an illegal source or not without doing what is expected of them to do.
If confirmed the money would be sent to the government and the casino would banned the account that received the money permanently while if the money was discovered to have come from a clean source then the account that received the money would be reopened and all the balances will be returned back to it - and the user will be notified of it so that they can continue their activities.
