Let's assume for the moment that Bitstamp was breached by hackers and at least all hot storage coins are lost. What do you think it would happen to the price? What do you think it will happen with all those sad fellows that lost the coins? And what do you think it will happen to the Bitcoin image?
I guess the price won't be affected too much at least few days.
I guess most of those that lost their coins will never come back to bitcoin again.
And I guess the media will be all over the bad news and Bitcoin's image will suffer the most.
Anyway, it happened before, it will happen again. That's the price for using CENTRALIZED EXCHANGES.
It is possible that the problems are bigger than what Bitstamp is saying.
