Can anyone guess which events may have caused the bubbles that peaked before 2013-10?
We call them growth spurts BTW,

I imagine 2013 -10 saw the first supply shortage, as AsicMiner brought the first industrial ASIC farm online and the few other ASIC'a hit the market. this changes the distribution and supply dramatically, I also imagine all those suckers who invested with Pirate40, bought back in during that time, that time frame would have given them just enough time to get over the tragic loss.
