The wise bet would be to dollar cost average. If you bought 2 million more shares at .0001, you'd have 4 million at .0003 average, or if u bought 4 million at .0001, then you'd have 6 million at .0002 average.
I admittedly got most of my shares at .00015 average. I will sell them slowly on the way up.
DISCLAIMER: I am a dirty, rotten penny investor. I am not compensated by any stock. I've asked them to pay me, they refuse. I buy stock on the open market. I sell it there. I like money. I am greedy. I am under the care of a psychiatrist.
