Is this becoming a joke or something? In every god damn Bitcoin thread there is a very smart person who always asks the same question. If you are so serious about it why not just use Google?
It is a legitimate question, though, with an answer that is yes you can, in theory, but no large markets currently support it, and the ones that do don't allow naked shorts.
As mentioned elsewhere in the thread, two that allow shorting look pretty sketchy.
So I guess it sort of is a joke. When do the markets for bitcoins start acting like actual markets instead of hype machines for bitcoins?

FYI asking this question does not make you seem like a financial genius nor is it a witty reply.
