Don't empty it. You think it's mostly about going short, but in fact, it's about being empty. Buying more without closing positions is just a number; only shorting continuously adds to the position until liquidation.

$ETH Who dares to draw the sword and stand tall? Seeing dozens of short positions trapped in the square scared me. If it dares to break through to 4800 tonight, I will short it and stand with the short-selling brothers.
