Tada,,,,,hummmm,,,I would think the safest play is owning the common shares,,,,,,,the most risk is holding warrants into top line results albeit leverage,,,at the very least with common shares one would never run out of time if we ever did get a 2nd or 3rd chance in trials to prove up epigenetics while warrants will evaporate most likely worthless before RVX would rise out of its own ashes. As one should realize by now that many an option has expired worthless all the while the common shares just keep on ticking!
