Advantis (ADVT) is on my streamer of OTC scam reefer stocks. Has been for a couple years. Back when the California fun use bill became law all these OTC scam reefer stocks went bonkers in 2017. When the bill went into effect in January 2018 most of them dropped like a rock off a cliff.
The Nasdaq's third tier, the AMEX can be just as bad, and last but not least, the OTC, it seems, are financial venues that reward failure.
