About contracts and spot trading.

Contracts are just a more flexible way to use your own funds; you can choose whatever leverage you want, even below 1x leverage, which is not much different from spot trading. The funding fees for contracts are much lower than the transaction fees for spot trading. I think trading with contracts is also cheaper; I trade quite frequently.

The systemic risk of trading does not come from whether you are trading contracts or spot; it's like whether a person uses a spoon or chopsticks to eat. The main risk comes from control over leverage. It’s about how much you can handle; those who try to take too big a bite often end up overreaching.

Those who say that trading contracts is guaranteed to lose clearly do not have much money and are betting everything every day; in their eyes, contract trading equals high leverage trading. They can never escape that mindset, so they claim that contract trading will always result in losses.

In reality, I have seen people make millions, even tens of millions, or over a hundred million, while still maintaining very good risk control. Of course, there are also those who have lost everything; profit and loss are two sides of the same coin, and those with poor risk control tend to lose more.
