If someone with higher risk threshold buys now at $.0045 and audits come out in the future that validate sales, PPS will jump to say $.01 and trend up. That investor kicks off that trend with a double. And if audits never come out and the PPS goes the way of the past, back to $.000s, he loses most of his investment.
Someone like me, post audit, gets in at a penny, but is more assured of continued north movement, makes a lot less. But if audits never come, he loses nothing, except time.
