Only those who sell short are masters. The master learns to sell, but the apprentice only knows how to buy. Moreover, meaningless altcoins are the highest level of high risk. What is the reason for value investment to fantasize about a thousand-fold increase? Moreover, it takes real money to pull the price up. Shorting only requires high positions. Who do you think would not sell when the price goes up?

Why do experts never short? A picture tells you

Theoretically, the profit from shorting is always <100%, except when leveraged. If you add leverage on top of shorting, theoretically the risk multiplies several times, requiring multiple times of margin to control the risk.

As for altcoins!

Because they are not afraid of you shorting, 1. there are funding fee consumption, 2. long-term shorting has low returns and high risk, and can be pulled back at any time.

Let's assume an altcoin is currently priced at 200, and you short it without any leverage; even if it eventually drops to 1 or 0.01, your profit would only be 99%. However, if it rises to 400, you will face a liquidation.

Conversely, going long! In the case of 0 leverage, it will never get liquidated!

In the short term, shorting can be profitable, but in the long term, it is not advisable, and the risk is greater than going long.
