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?
