Interesting, but I think the timing of the selling of Mt. Gox bitcoins could really be the big factor. Charts are great when supply is stable and other factros are held constant, but do a poor job of accounting for fundamental shocks. I think Mt. Gox counts as one of those shocks. Now there have been reports that they were not going to sell for a while, but there have also been reports they are moving them.
