Interesting....adding over time is an approach that I've chosen to take here. Risk is having it take off and getting left in the dust. That said, I tried to get another 1 mil. today at .001 and could only get 650k. Not quite to 24MM but do have multiple millions :) Will likely continue to add and if it takes off....well that is fine also.
Your cost basis at this stage of the game is not material. .0014 per share is a gift. Just wait a couple of years and I believe your stock will be worth several dollars. it all depends on how fast they move. All my opinion only, do your own DD.
