The options are priced correctly by the market! You guys don't seem to get what a time premium in options trading means - 3 years is unusally long and you pay for that. If the heads get to 10c in 2 and a half years - the options on face value will be worth 8.8c + the remaining time premium + a volatility premium. Say 9c to make the maths easier - then from 0.5c to 9c is 18 fold - FPO's from 1c to 10c is 10 fold.
