OUCH~ Down 51% today!
I would avoid all pennies stock because it can go up and down so much in one day.
If you have few thousands you can risk, then do it. You might be able to make a quick double in couple days.
But I wouldn't want to risk $50K on pennies stocks.
I rather you bring your money to casino and play Baccarat. At least is 50/50 chance (excluding 5% commission).
