Bear markets often see sharp rises; with such poor liquidity in the crypto space and so many shorts, it's normal for there to be a crazy short squeeze. As a smart short seller, the goal is to short him aggressively at high points until the bulls are defeated.

If you want to attract bottom-fishing bulls, you need to force them to keep bottoming out and continuously push for new lows.

I admit that my way of speaking is quite dark, but the reasoning is as follows: for a short seller, ammunition is the most important.
