So lemme get this straight: The exchanges that haven't transferred to 2.0 yet, those are effectively worthless, so people are selling those for cheap, in order to buy the ones on polo but there are people arbitraging the ones on polo to buy even more worthless ones, thus bringing the price down in a brutal feedback loop? I'm confused because polo lets us withdraw them so shouldn't that mean all the ones on polo should be getting bought, bringing the price up on polo and lower on the other exchanges?
