From my point of view, we need someone huge to announce Bitcoin acceptance, like some from top European countries. Or wealthiest company like Apple, Amazon, Microsoft or Alibaba Group would buy a large amount of Bitcoins. Or worlds wealthiest persons like Bezos, Brin, Gates or Buffett would announce they make large investment in Bitcoin. I think that might trigger price to go up. We need a strong price push to provoke huge growth. Without it, with natural price growth, it will take a lot of time or unknown amount of time to reach new ATH.
