Not much has changed on OTC, except for one.
All previous stop sign tickers have either been removed or have become Pink Current/Limited.
Custodian and sub penny plays have, generally speaking, always gotten the most action from OTC day traders and flippers. As long as their favorite tickers remain Pink Current/Limited, they will continue to be the tickers that see the most "action" and the largest percentage short-term gains.
Presumably legit tickers, like ALTD, will likely continue to suffer from inaction from most active OTC traders.
All is just my own opinions.
