First, when investing in penny stock, you have to invest with the attitude that it is a possibility that you will lose it all which it why you invest with what you can afford to lose. Now, I recommend that if you doubled your investment, take out your initial investment and play with there money, if you lose the profits, remember that you didn't have it in the first place.
As for what is going on with the stock, I called it, but the fact that it plunge to what I said quickly, in my opinion, some good press release will be issued, if no, then we will laggard for a long time and they will pull a reverse split to attract, meaning many will lose money. Again, this is just my opinion. I called it and it happened to fast, I was not expecting that, which is why I feel something will follow.
Glad you pulled out and if you own shares there is no need to buy more unless you want to risky it.
I do not believe those who say they are buying more to increase their position unless they give an odd number of shares before buying and it is fulfilled and we can see that odd number of shares that was bought.
