Look at it this way: Bitcoin's deflationary nature ensures that gravity pulls it up. So if it goes down you know it's a good time to buy, almost always! Shorting Bitcoin is a little insane, I think. Although, I took a chance, and made more than 100% shorting it just as the news broke... timed the bottom, and bought on the way up. Mostly luck, timing the bottom... but it was a "solid resistance level".
