I own slightly more than 3M shares averaged at .0018 or .0019
As far as where I would sell them, that's a really difficult question because it would depend on whether or not there is some type of a catalyst that will turn the company around. In order for me to make my decision, I would have to see an increase in volume as well as perhaps a change in management or some other type of catalyst.
Under the right circumstance, because I do follow this stock, if good news were indeed to arrive, I would be more inclined to actually add to my position rather than sell my position because my cost basis is so low but if I average up while the stock is reversing trend, chances are I will make a lot more money then if I simply held onto my core position and rode it up
