Yes, there are. Quite a few, but all of them are registered and reporting to the SEC, and almost none of them have boards on I-Hub. They don't appeal to the typical I-Hubber, as they are much more focused on building their business long-term which has no appeal to the average OTC trader. These companies usually put out only a few news releases, and instead most of their information in contained in the SEC filings every quarter. They also don't hire promoters or pay for stock promotion to individual investors.
Investors actually have to look to find them because unlike most stock scams, they won't find you.
Yes. But they're mostly banks and foreign companies that have ADRs in the U.S. They don't attract attention. There're a small number of other legitimate companies. Each year, about 80 "graduate" to a national exchange. But they don't seek attention, either.
