I know it's a crime, but, I believe uspr board members, as well as director's, sell shares back and forth. Paying the 5 or 10 dollar trade fee (as well as tiny up-tick 5-or-10%, slightly turning PPS green at business end) to give uspr the illusion of volume, false volume.
Then with a paid advertisement, drawing new/unaware investors in, and that's a real pump the dump uspr.
