I'll just leave this here:
i never understood why people believe that bitcoin price is a bubble in the first place and not normal price fluctuations in a free and unregulated market. Especially after 2011 so called "bubble" when no one know what will happen next and now we know that bitcoin wont simply die next day.
I and I think many others just bought bitcoins, keep them in safe place, and remain optimistic because we believe its good concept and worth investing. Where is bubble in that?
I think you need to look for the definition of a bubble. Bitcoin bubbles are textbook examples of economic bubbles.
This does not mean anything bad in and of itself. Every free market that is exposed to occasional hype, growth spurts, volatility and promising futures will undoubtedly go through one or several bubbles before it reaches any kind of price stability.
