You must have picked companies with real potential, and they do exist in the OTC, I disagree that every stock in the OTC is scam, just most.
Scams tend to be short lived, you get in, if you don't know what you are doing or don't trade the price only you can get caught as a bag holder... but some companies do have true potential, they are rare.
TALK, because it was a reverse merger, acquisition, a private company with big plans changed TALK's game, and some see the tremendous value in the new TALK.
Holding for pennies or more still.
