Nobody ever said that one should buy millions of shares in such a penny stock. Everybody with a few hundred thousand shares is easily out by now with a nice gain. Certainly not a playground for you since you would need to buy 10 million shares in order to make it count but that's what I always tell you.
All in all I think this could even get interesting from here in the future. Now that they are debt free basically, the new owner of the shares will certainly try to get some serious business going and they already said that in the PR's.
Everything below a cent "could" get interesting again.
