MTGOX nightmare is sleeping but we cannot know when its going to awake up.
there was never anything called "MtGox nightmare" ever to want to wake up now. there however was FUD and dumb people in the market who fell for that FUD.
this was discussed multiple times already, Mt Gox was never the reason for the drop for many reasons including the fact that they were selling a long time before the drops even began and also the fact that they explained that they weren't even selling on the market to cause any kind of crashes.
at some point people wanted to push the price lower so they started the drama and people fell for it. so it was another FUD like anything else. and you can not use the same FUD many times, it only works once.
