While normally I would agree, specifically the OTC is not known for the high degree of scrutiny as the oversight enforced by the SEC on NASDAQ and NYSE. That’s why companies aspire to get off the OTC.
I personally have put some of two my IRA funds into nFusz after a significant amount of due diligence. I am not recommending this for others, however each needs to understand their own time horizon and risk tolerance. For risk vs reward I am seeking, there are far more risky plays on the NASDAQ and NYSE in my opinion.
