Not really. Biglies have sales and profits that are distributed and often coincide with stock price. Yes, the actual sale and purchase of the stock itself can cause ppl to lose at someones expense, often though, the benefit of stockholders in the biglies is dependent on the consumers, who are provided a service.
Big boards are susceptible to scams and crashes just like everyone else. Trading OTC is fun and risky, but my money is mostly in the bigs where there is a little more stability and predictability on volume/sales/profits/filings/earning reports...
Fewer rather than more OTCs have a company making profitable revenue and distribute that through dividends. Mostly, like PZOO, trades are made off of potential future value and hype surrounding "news"...which often ppl get caught in the high end and left holding the bag while ppl profit off those buying on the high end.
Sorry if I'm answering on a basic level, not trying to insult your intelligence if you already knew this...just trying to be helpful.
