That's probably wise if you're new to investing, and particularly OTC trading (which is really much closer to gambling than investing).
That said, they did just air an ad on Sirius radio, so you might wanna hold on to at least a few shares in case the improbable happens. I would wait till you learn more though before going all in on any of these stocks. It can be a very expensive tuition and, especially with trip-zero stocks, the losses can be quick and steep.
It sucks to sell out and then watch a stock go up 500% (happened to me twice the last couple months), but it sucks even worse to hold a stock and watch it drop 80% over a few days/weeks and never recover (happened to me more times than I would like to admit). All about timing and risk/reward. Good luck
