Alpaca Bob noted:
"A lot of people who want out of Gox buy bitcoin and move that to other exchanges to cash out. This artificially drives the price up on Gox."
I think this is probably true. I wonder if in turn that was driven by issues with MtGOX recent bank and/or Dwolla account issues. Perhaps after a few things resolve the exchanges will come to closer agreement.
This is just a bit of speculation based on my very limited experience. Still excited to see this economic experiment unfold, it could certainly be bigger still in the future!
Best wishes for everyones success!
