this is why centralization is dangerous especially if combined with bitcoin where there is no regulation, you get the usually "i was hacked all funds vanished"
bitcoin should only work with decentralized system for anything
Being hacked or robbed is not excuse to not be blamed. I imagine if you are businessman you must be aware that money of your clients/creditors you keep are your responsibility and you HAVE to give it back even if you lost it.
i'm not finding excuse, i'm saying that bitcoin does not work well with centralized exchange, because there is no regulation usually, where in fiat only exchange they are 100% regulated, and there is insurance, real insurance
now with bitcoin only coinbase have real insurance, because it is heavily regulated, basically any exchange that has not insurance like coinbase cannot be trusted with your money-in
