I was invested in a Nigerian Bitcoin mining company that went from .0008 to 5 cents. With a website made on Windows 98 technology. So what. It was scammy as all get out. People made money anyway.
Who remembers MCET? That company didn't even exist anymore, it was an empty office with a phone...... and it made the "OTC papers" and shot up 1000% on some kind of vague news before getting delisted in the big SEC cleanup of dead OTC tickers.
Regen actually has something going on with it, and is active.
