I wouldn't buy at .07, there is no real difference in .07 and .10 as far as risk goes. Don't know what would make it a better risk at .07 as opposed to .12. The price is not really the determining factor here as far as I'm concerned. Nothing is going to change at .07 that won't exist at .12. The uncertainties will still be there. Of course you're free to make whatever choices you make. The uncertainties were there at .02 and continue to exist, but I think you underestimate the positive factors in play that were not there at .02. If I were you I would wait until it goes as low as it can go, if it's .02, buy then. If you don't wait, you might miss a good opportunity to pick it up really low.
Anyway, have a good one.
