I don't think BitStamp is dead just yet, actually I think they'll do just fine. BUT: Many people are going to want to play it safe, which is wise, and do their trades on Kraken. It's the go-to choice for people located in Europe, apart from Stamp and maybe Finex.
If a exchange gets hacked ONCE the stab of distrust stays forever, and people start migrating towards other exchange (that will eventually get hacked too). And so the bitcycle continues.
Lets just hope the winklebros fix this.
Gox showed us that this isn't the case at all. There have been many instances of problems with Gox over the years, yet people stored hundreds and thousands of BTC on it. If Stamp proves they do hold the BTC and FIAT, they're safe. I think they may be more careful than others since they took a hit.
