I don't think the next spike can be $560,000 14 months from the date of the OP. That's next November and would have to go up from today's price by 2240x. It's never done anything like that since it went from 10 Bitcoins a cent to $2 when it started off. Those kind of price increases would need billions of dollars throwing at Bitcoin to happen today. In the early days a few thousand dollars would pump the price crazily.
He was just playing with numbers, and I get his point about black-swannish nature of bitcoin's potential valuation.
Alas, Oct 2010 to July 2011 move (10 months) was from $0.062 to $35 (I don't have numbers beforehand).
The equivalent in %% is a move from $260 to $132000, not that I expect it...just numbers.
