But in the case of the casino, once it's hacked that's the end of that casino, only big casinos offer refunds or protect their player's money compared to exchanges where they can do a refund and insured their trader's money, I don't think there's the same guarantee that they can offer that they will do a refund.
Well, it all depends mate, if a really big casino is hacked, what it really need is decision, if they decide to go on or continue, they can still put their shit together and continue, they will at last strive and survive, it is the same with exchanges, even smaller exchanges don't survive when they get hacked, if you've been in this space long enough, you should know cryptopia, cryptopia was my most favorite exchange back then, I lost a lot of money on that exchange when they got hacked, though they claim to have refunded customers, I filled the form but never heard or received anything from them.
Exchanges are bigger and a more serious business than casinos, and I think this is why casinos don't survive after they are hacked, but like I've said before, it boils down to decision, and one of the factors that influence the decision is the impact of the hack, how big or small it is.
And one other thing I will like to add is that, when big exchanges get hacked and they decide to quit, they have more to loose than a big casino getting hacked and deciding to quit, building a big exchange is a tedious task and process compared to casino, this is why it is very hard for exchanges to give up easily because they loose more when they quit due to hack.
