Most likely the share price will sit fairly stagnant over the next six months anyway. Give it a longer timeframe and fix your terminology (your suggestion of betting on whether it will be more or less than 50% of its current value in six months does seem sort of appropriate, but I'd guess it will be above 2.65c in 6 months) and I'll probably take you up on it.
