So far that gives an average weekly change of 6.4%, including the data from all the way back to the first day Mt Gox opened.
Using that gives about $300 by the end of the year, with $1000 being reached slightly under a year from now.
I have been tracking things in a similar way and have projected very similar numbers, but things could move much faster. It's possible that in addition to increasing adoption, the rate of adoption will also increase, add to that the fact that the supply inflation is dramatically lower now than any time before about a year ago (when the block reward halved) and I think there is a real possibility that the price could melt-up in a dramatic price explosion, not unlike what we saw earlier this year.
this must be why your name is impulse.
