"If you are not optimistic about a project, you can open a short position"

This sentence is logically sound, but it is actually wrong:

1. If retail investors are not optimistic about XXX, and they open a short position with leverage, will they use the cheap spot chips in their hands to smash the market and stop their short positions?

2. If retail investors actively open a short position, and the dealer, as a market maker and counterparty, passively opens a long position, will the dealer use the spot to smash the market and give money to the retail investors' short positions, and then let themselves be liquidated?

3. The needle of the K-line is used to show users after the liquidation, not for users to buy the bottom. If the commission price you set cannot receive the needle, the exchange will tell you that the price depth is insufficient (but please rest assured that the depth is sufficient when the liquidation occurs)

So, if you are not optimistic about the project, don't participate, instead of opening a short position.
