WOW, you must have huge balls to keep such an amount on Scox.

Generally speaking, I think we should fasten our seat belts and get ready for the worst scam in Bitcoin history. Let's face the facts. Most likely, the story about a technical issue is plain bullcrap. And by now, also the most naive Bitcoiner must have realized that Mt.Gox is not to be trusted as a trading platform leaving those crooks with only two options.

A: Take hundreds of millions in customer funds and disappear enjoying la dolce vita on some private island somewhere in the Pacific.
B: Announce that everything is back to normal and watch 99% of all customers instantly withdraw their coins.

As far as I am concerned, it's kinda obvious what it's going to be.

Not only do they face a simple decision, but it also seems like they got ready for this very moment quite a while ago. According to the article "The rise and fall of the world's largest bitcoin exchange" published on wired.co.uk (7th of November 2013), Mt.Gox not even has a physical office anymore. And of course Karpeles and his gang weren't seen in a very long time as well. Plus, they might start feeling some heat after Shrem and Faiella's arrest. 

Well, let's hope for the best while preparing for the worst.

Good luck.
