Nobody but me is shorting. Just look at BFX.com. Only 691 shorts opened up in the last 24 hrs. All the short-sellers (except me) got wiped out in the November spike. No, two million bucks worth of margin longs deleveraged to bulls. That's all. That means they only have another 24 million to deleverage before they can pull their damn coins out of BFX before it goes GOX.
This is the simple reason why shorting BTC was just plain dumb.
There is a limited number of BTC available to borrow to short Bitcoin.
On the other hand there is an infinite number of dollars available to borrow to leverage long into Bitcoin. You guys are complaining about $24 million leveraged longs on bfx, well the banks have over $100 trillion in leveraged dollar longs. The supply of dollars to borrow is infinite.
Just wait until the Gemini exchange in wall street gets going. It's going to make bfx look like a doll house. And Gemini will have access to all the dollars in the world to lend to people, but they will have very few BTC to lend as well. You do the math.
