yes, but again, I have the money to buy the BTC which I then want to turn around and sell short to someone.  how do I use the BTC I have to short?  its like I'm forced to borrow whenever I short.  why?  do I short on margin then CLAIM right away?  but I still pay a lending fee, for what? 30 seconds while I click CLAIM?  maybe I don't understand it well enough.
