Something to keep in mind when using anonymous casinos, they should be treated like mixers. If they suddenly disappear, there’s no way to recover your money. To keep things fun and minimize risk, it’s best not to be too aggressive with your bets. Only wager what you can afford to lose, just in case the worst happens.
The anonymous casinos can disappear anytime they want without they notice to their members. Besides that, they can apply strict rules to their members to prevent their members withdraw their money. That is already happened with the casinos out there so we must be careful if we find some anonymous casinos. We better choose regulated casinos than anonymous casinos especially if we don't want to be the next targets. We need to spend the money that we can afford to lose so we don't have to regret if we lose or getting a scam from the casinos.
As if a casino with license can not do it? I think nothing stops any casino from disappearing suddenly or announcing bankruptcy. Those who have money and power with help of lawyers will drag something out from such situation, but majority, who kept money there, will only complain and do nothing. By the look how people are careless about their money, how lazy they are when it is time to fight for their stuck, frozen or stolen money, it makes no difference if it anonymous or centralized casino with licenses.
