Well at this point China is dragging the markets along with it. It's really in the hands of the Chinese how far this rally goes and how long it lasts. If the Chinese want to take us to 10k cyn they can do that.
But long term this rally is unsupported by anything "real". I'd love for this rally to be occurring on the heels of the announcement of new bitcoin technologies or some larger retailers or Paypal implementation, etc.
Instead we are on a Chinese roller coaster. And trying to predict where it's taking us short term is simply impossible.
