Big names like Metawin and Stake survived hacks before, and players got lucky their funds were safe. But if it’s some random casino with no deep pockets? Good luck. Inside job, outside job… either way, don’t expect them to hand your money back out of kindness.
And waiting for a third party to help? Yeah, sure. I’ve seen that with exchanges, but with gamblers? Nope. Not once.
So if you’re betting on a refund, you might as well bet on winning the jackpot too -- same odds (correct me if im wrong), I guess..
It may depend on whatever it is said in their terms of service. If it is written there do not have insurance against hacking and digital theft of their wallets, then I would not expect them to give me a single Satoshi back, honestly. Probably, most small casinos use their terms of service (which nobody reads), to ensure they are not held into account in the case of a serious theft/hack.
By the way, exchanges do not want to get directly involved with the rescue of casinos, because it would be bad PR to them, gambling is very stigmatized, as we all already know and the least a exchange needs is giving an image that could turn away depositors.
