Unfortunately there isn’t anything you can do but learn the lesson. 99.5% of the OTC is scammers. It’s high risk gambling and you never hold shares long and take small profits immediately.
I am at a loss why anyone actually bought this. The company closed up years ago and I have been a stuck holder for years. A year ago, a careful pattern of buying of this dead stock emerged. I always wondered why. Now I see why. The rumors of a R/M were part of the scam from what I can see. (Only hope I have of ever getting out of it.) It was well done and crooked to the bone. I was not able to get to a level that I could have bailed from it to at least get most of my money back. Now I have to sit back and just see what happens.
