You can lead a horse to water but you can't make him drink. Investors here will learn the hard way, unfortunately. Disregard the relentless pumpers on this board. Take your profits and run. This certainly will go much lower.
You need to distinguish between pumpers -- those who mix-half truths and innuendo in order to push a stock higher -- with true believers who have examined the scientific potential of this company and its PBT2, PBT434, and PBT519. But you have a point, in that one has to accept higher risks for a company like Prana.
