Autumn 2012 felt the same as now. The infrastructure developed rapidly, adoption increased, the good news just kept flooding in and the price did not react at all. That was also after a long and terrible decline after the crazy 2011 bubble. Of course nobody knows what will happen but I would not be surprised by something similar to spring 2013. Interestingly, a widely held belief around here in 2010 was that if this thing takes off there will be bubbles, several of them.
