Disagree there - any risk can be quantified and minimized if you do DD and diversify. If you have a basket of OTC BB stocks and carefully time buys, not all at once, keeping track of the filings and chart, you can have very large overall gains. Sure, you will have losers, but the multi-bagger gains is why many play here. It goes without saying that one has to recognize the risk, not go along with the "crowd" and, again, diversify, and step gradually into any play to have a chance at the payoff.
