That is only for you to decide. Are you ok if the share price gets cut in half next week if bad news comes out? The reward in holding IPIX looks to have much higher potential than your average OTC.
Plenty of smart folks on this board (not me) willing to let a few dollars ride or die!
If all the rosy predictions and best-case scenarios come true and we're not diluted then the share price here seems to be a bargain.
