I've got a couple now in the 2-3 cent range. 1 million shares would be $20,000 to $30,000. That's a little steep for the avg trader, methinks. Definitely steep for me; I've got 239,000 in one and 140k in the other. I'm not sure many ihubbers have more than 500,000 shares in those tickers. So it all depends on PPS.
If you meant to say trip 0 stocks then 1 to 10 mil sounds right for avg trader.
