Dont get yourself under delusion that the next bubble will be at $2000 and after that the price would be stabilized at $1200. It is 2015 and people are not stupid to fall into another bubble anymore because the peak of 2013 has burned alot of people.
Memories suddenly become an awful lot shorter when there's the belief that there's money to be made. People will talk themselves into anything when greed strikes.
This deflation has been epic and could be far from over yet but the reasons for another buying frenzy are arriving every day. It won't succeed without a few more bubbles on the way. It isn't necessarily helpful overall but if you throw in limited supplies, a small market cap, tiny number of users and future potential it's inevitable.
