When playing contracts in a bear market, the losses are generally not too much,

but in a bull market, the losses can be significant.

Institutions are very skilled in the market, exchanges can easily make money, but retail investors suffer, always being cut down like leeks.

When we invest, we shouldn't have too high expectations, and we shouldn't use too much leverage. The market is just this big, and those who make money are basically the ones who hit a good timing.

If your gambling nature is too strong, the money in your account will definitely be gone in the end. You may think you have insight, waiting for the main rising wave of the bull market to make a big profit, but to those manipulating the market, this is just a joke, and then you will be crazily harvested.
