Shorts are up 3.5k since the top. Longs at 22mil$.
Outwith Dec 2015, Shorts on BFX have never been so low in over a year.
Longs are also relatively low, but you would have to go all the way back to March 2015 to find a period where long positions on BFX were comfortably lower than they currently are.
But probs we need to be looking at CNY markets to get a better picture of this, as it is China that is driving BTC at the time being.
There may be some contribution of Chinese exchanges to BTC's price movements, but really overall Chinese exchanges are lacking a certain level of credibility to be true drivers of BTC prices in any kind of meaningful way.
