The above mentioned sites aren't exactly for options.
i am not yet found a market exchange that giving Options for bitcoin, because as far as i know, its only available in stock. maybe for next year, there are a service that provide Options for bitcoin. for the honest, i really don't know how to trade with Options, maybe i will learn from the book.
I believe its because bitcoin is volatile, so anyone selling options is probably taking a lot of risk specially because he could be giving these away in bulk.
