I have traded stocks on and off for several years but mostly big boards so buying and holding was a good strategy... i only started getting into pennies earlier this year with the MJ rush (hence my alter ego name ha) and have learned the hard way that get in and get out quickly with profits is the only way to do it.
I threw away large profits on lots of penny stocks (not just MINE although that was by far my largest single loss) just because I was very stupid, naive, and not used to the OTC jungle.
