I read this yesterday:
''I am sure no one reads this as all the delusional bitcoin fanatics downvote anything negative. But in case you do, and in case you share the same 'opinion' as I do, here is a little tip from an 'insider': as I am close to an exchange, a huge dump is planned in the near future. The exchange will go temporarily offline (like many times before) in order to fulfill the sell-orders successfully. There is a special reason why I am writing this, but I will not disclose it, as it might harm me.''
I can't find the comment anymore but it was posted somewhere in a bitcoin related thread on Reddit.
I think it is true, with all the negative news coming from China.
I think it is a good idea for you to get out. If these types of things are going to cause you anxiety then you should move your money somewhere safer because the currency portion of bitcoin is going to be a wild ride; for some time.
I don't think I trust Mt.Gox anyways, I'm still searching for a more stable exchange.
