That's how you play these stocks. We can all get excited about the long term potential but if we are wrong then you can be glad you made a few bucks along the way. Besides its more fun this way. And selling a handful of shares at .30 doesn't affect the overall momentum if it is for real.
For my part I sold 1/4 of my holding yesterday at .3 and I have a buy order at .22 currently. If I fill great, if it runs, even better.
