I'd rather invest in a real company than a scam - it lets me sleep better at night. But hey, that's just me. If someone can play a scam and get in and out before the whole things collapses, more power to them.
Take for example, a ponsi scheme. The way a ponsi scheme works is that investors are paid their profits with the money from new investors. But when there are no new investors, the whole thing collapses, and when that happens everyone left in the scam is SOL.
What's the difference between a pink-sheet scam and a ponsi scheme? There are lots of differences. What do they have in common? When the gig is up, you can lose most or all of your investment in a very short period of time, without any possibility of recovering that investment.
Now, what's the difference between a stock like WNBD and a pink sheet scam? The difference is there remains a possibility of recovering your investment. The pps can move back up (as it has in this case many many many times before) and it's up to people with enough foresight to recognize a bottom and capitalize on that play, well other people with absolutely no foresight will get impatient, disgruntled, ect. and sell near a bottom for a huge loss. And there lies a key difference between people who make money and lose money trading stocks, IMO.
I know it sounds counter-intuitive to buy shares when the stock price is depressed...but then again isn't that part of investing 101?
