Yes. A FEW YEARS BACK! Much has happened from a few years back to now. The company has grown, progressed and evolved. As of now, 2017, the play is what the play is. Buyout w/zero chances of uplisting.
They are still in startup mode. Should they decide to not be bought out, once the necessary patents are approved, then they will uplift.
I do fully understand the play. I love it when the pps goes down because I accumulate when it does. As do many. But yeah, for those that do claim they know and understand that this is a long term play, need to do what you say. ;)
