Revenue is still the key to move the PPS up. No need to be impatient, if you bought because you believe in the technology and the company leadership then have patience. It takes time to build a company.
Many OTC companies have no product or service to offer, hype not revenue drives the PPS up. If the hype is strong they run up quickly and fall back just as quickly. OTTV's PPS is still considerably higher than it was just a few months ago.
By comparison if this was a $1.00 per share and had gone on a similar run and then leveled out at $3.00 per share most would call that a "big" win and celebrate what great traders they are. The PPS is relative, I invest in these sub pennies because I can have millions of shares with little risk, if they run big I win big. I know full well that my investment may disappear and I accept that, for me that is what makes it entertaining.
