I cant figure out why anyone would call $100 cheap, they were half that a month before, and half that before the bubble started.
Best thing that could happen would be it crashes back to $10-30 and stays there for a few months at least. That will drive out the speculators and manipulators. I doubt that will happen with all the hoarding though.
A significant drop in price will make that: speculators and weak hands to sell. That would be beneficial for a healthy future of Bitcoin. I read a lot about price opinions: some people argue it's high others it's low... the real truth is nobody knows what the fair price or fundamental price is.
Monetizations are a roller coaster and this volatility is very common in the process and it won't be the last slope.
I really hope bitcoin goes much lower for me to get into, I think there is a chance for bitcoin to prospere. For me the current price (94$) seems like too high. My memory is set to 4/10$ a btc, higher than that my head thinks it's expensieve. But again, nobody can't really tell me I'm wrong (and I'm 0% sure that I'm right).
