#BTC The author never shorts the market, even if it falls from a high position, why? If something has a long-term upward trend, people who like to go short will sooner or later be pulled out of the game at a certain point, and the pie will also fall. As long as you keep on falling all the way to cover your positions, you will eventually hit the bottom. Yes, unless it returns to zero, will the current pie return to zero? Will it return to zero? ? ? Is there a global boycott? not at all! ! ! Therefore, there is no need to go short if you are determined to make the pie big!
