Interesting. Why do you think they're going to fall?
(Don't worry about dissuading PUT-sellers, the discussion would attract more!

)
I've done some statistics with the rate of difficulty increase and the anticipated hashrate increase. They're overvalued.
(I DON'T think they're gonna fail, but I think the odds of being below 1.7
BTC before September are worth up to a 0.1
BTC premium.)
Such an option is worth about .25 BTC actually. I'd write you a few at that price at the lowest.
