Well, you could look at the charts of exchanges before mtgox, like bitcoinmarket.com with data from 2010:

PayPal USD: http://bitcoincharts.com/charts/bcmPPUSD#czsg2010-01-01zeg20...

LibertyReserve USD: http://bitcoincharts.com/charts/bcmLRUSD#czsg2010-01-01zeg20...

Bitcoincharts has a log option... Its right there on the same page you just looked at.

EDIT: Also check the date range, Bitcoincharts has almost all historical data.

I always use that log option. It's amazing that people look at the normal chart.

Jeez you made me do a doubletake! You know there is a log option! Damn I look stupid now, haha.

So you were only asking for extended data? Does the all time option have enough for you? I don't think Gox traded back past the data bitcoincharts have on record.

No worries. I'm curious to see data past what bitcoincharts.com offers. If you look at their three years of data on a log scale, there's a very clear trendline with gains of 6x to 10x per year.
