A work mate of mine (who isn't active in Bitcoin) was being all super-sceptical and bearish on BTC today in the office, saying it's going to crash further, it's a Ponzi, blah, blah. I encouraged him to either put his money where his mouth is or shut his trap. So we started to informally price-up a $1000 Call option expiring 11th Dec 2014 that he would sell.
I've calculated the recent realised vol (30-day rolling window), but was just wondering if anyone out there has quoted or traded options recently? Any ideas where implied vol. would be bid out there?

He now seems tentative to sell 150% vol. Anyone reckon that's value?
