I don't think they will die in one go, it looks like they will experience a slow death instead with people moving more and more funds out of the exchange over time. What this means is the impact is likely to be minimal rather than a situation like gox which more or less went offline overnight.
Apart from them fixing up and getting back on track this would be the best outcome.
Shocking how they've let something that was so great slide so badly though. You would think with the money they are earning every single day that they would be able to pay an army of support and tech staff to address issues.
Moving admins from their trollbox over to support, that still don't bother replying to anybody, isn't a sign of competent management.
