This is what you would logically conclude by looking at the situation at a glance, but this is not true. Sure, Mt. Gox has the capability of operating just fine. Sure, they were vulnerable and needed to stop withdrawals temporarily, just like several other exchanges that had the same vulnerability. In fact, Mt. Gox did a service to some other companies by providing a warning that the risk of this vulnerability is becoming critical.
HOWEVER, this is NOT the reason Mt. Gox is not, and WON'T recover. The reason they won't recover is because they are taking a crap all over any sort of trust anybody could have had in them. They blamed bitcoin fundamentally and denied their own responsibility. A decision has already been made ever since Mt. Gox addressed the public about the withdrawal lockdown that they CANNOT be trusted, and it is not only based on this most recent folly, but many past mistakes and irresponsible public relations.
I just wish they would just give up and kill themselves off completely somehow.
