As I wrote in this thread, I'm short bitcoin (at least until it reaches $8,000, we'll see then):

I do flip from short to long / increase my short position from time to time.

Temporarily closing my short position and changing to a LONG position now. Bitcoin is currently trading on Bitfinex @ $10,634
