If you're nervous, you shouldn't be in penny stocks or this sector.
If you look at the big picture of things to come, the upside potential is HUGE, versus the downside.
I have over $200,000 invested in VDRM and OWCP, and I'm holding tight.
If you try and day trade your emotions will get the best of you, and more often then not you'll not time it right.
