Why is shorting more difficult and dangerous than going long?

Because the financial market is full of games, and no matter how much money the short seller has, they can at most bring it to zero, and the returns are very limited. They can only increase returns by leveraging and taking on more risk. However, once the capital of the short seller reaches a certain scale, it will definitely be targeted by the opposing side. The long side can raise a large amount of money to increase several times. Moreover, this large-scale shorting is often done with borrowed money, which means it comes with additional interest costs. The long side may only need to spend time to blow up the short sellers.
