Updating, since the x10 exponential growth is, obviously, over, and we seem to be reverting to the x4 baseline growth. That line now offers support at $180, so if the previous ATH at $266 falls we could still go down 60-80$ to bounce off the long-term bottom line.
Just for some optimism, that bottom line crosses $300 at the end of January 2015, and $1200 at the end of January, 2016. For a historic reference, that bottom line was not once breached in bitcoin's history, even in flash crashes (mtGox hack does not count). But we did deviate from it quite a lot in 2013 to the upside...
