As a veteran of the penny stock game I would warn it can be much worse than people realize IF THEY HAVEN'T HAD THE EXPERIENCE OF A STOCK GETTING BOOTED OFF THE EXCHANGES.
Here are some trades from just one of my accounts and this image only reflects about 2/3 of the trades (because this is all I could screen grab). Every number here was formerly a stock ticker.
In addition to these stocks which are now reflected as CUSIPS and untradeable (even though at least one of them still makes SEC filings) I have had MANY of the CUSIPS removed from my account under --- whatever they call it -- somethink like "destruction of securities act" ---> whereby they remove the cusips informing you that there was no TA and no market for the stock. I've lost track of how many of those I've had.
If/when this happens with a stock --- and you've never experienced it before --- its a rude awakening. As you can see, I've had so many such awakenings one would think me altogether SLEEPLESS.
...but winners have overcome losers, so its all good.
