Wasn't the price of 1btc actually a very stable growth till about sometime around the middle of last year when the price just skyrocket? Seems like the price has been more volatile in the last 6-8 months then ever before. I might be wrong though
Only if you ignore the summer of 2011.
2011 was nothing compared to what it did last year only about 4 months ago
If you look at it in terms of dollars the price moved, yes the price of 1 BTC has grown by a lot more dollars lately. But if you look at it in percentage terms, 2011 moved much quicker. $0.1-$32 only took only 9 months. If we started back at the $65 low that this rally to $1240 began at, 320x would be $20,800.
