I think the lesson is that if an investor generates information inside their own head against all evidence then they will always have a reason to believe in PTOI. Short interest in PTOI is virtually non-existent according to FINRA (around $100 worth) and PTOI isn't on the Reg SHO list. Discounting those two official sources and imagining a massive number of short sellers aggressively manipulating the stock and biting their nails waiting for the inevitable hammer to drop doesn't make it true. That's a ludicrous notion to believe and probably has made, or will make, paupers out of all who believe it.

Likewise I saw another person opine that "they" can't even keep it under a penny, obviously that person is also carrying a belief that short sellers are to blame for PTOI's price. The "they" is actually the longs who believe in PTOI enough to keep the price up around a penny. Nobody else is controlling the stock price. There are enough longs who "won't ever sell" and enough other longs to keep throwing $100 at PTOI every so often for the next decade or two to keep it over a penny in case any longs do sell.
