It's not all about hitting a home run on every ticker you play. Sure, most are scams, or dreams of someone who starts a company and has to start in the OTC. Most of those fail anyway. Personally, I could care less if a ticker is a scam. I get in low, and get out on a run. A .0003 ticker that runs to .01+ is one nice return, if you can get in on one. $1k in at .0003 turns that $1k into $33k. Or somewhere in between. So what, if it's a scam. trade the scam. I don't care if they're gonna mass produce the "Latest, Greatest, Fancy-Dancy, Game Changing Left Handed Monkey wrench in Timbuktu", If I can get in at .0001 and out at .01+ (or somewhere in between), I'M IN!
And on rare occasions, you do hit a real one that makes it. Depending on how much risk you took, will determine the reward.
Happy Trading :-D
