What happened is that some guy decided to dump and the bitcoiners stopped buying out of fear.
Let's face it we are on our own right now without newbie buyers. Any sort of mass adoption is 20 years away. It's time to stop looking at the graphs and dreaming of the moon every hour. The moon will come in the distant future when we are old.
Everyone who could be an early adopter is already one. The geeks and foresighted people have already joined. The laypersons will now not join until they have incentives. Thus there will be no more big bubbles in the near future. The rush of people who could have caused a bubble have come and gone. Now all we await is a small trickle of others to join us for the upcoming years. No more bubbles an time soon. Just a very slow and volatile grind upwards. Bubbles will happen with incentives and I see no incentive at all except a financial crisis that entails hyperinflation or banks repossessing money.
Out of all the countries in the world at least one will have a major financial incident sometime soon. Another thing could be if bitcoin is made very user friendly a new type of non tech person could become involved.
