Most spot market transactions are allowed to add leverage, and the leverage ratio is often several times or even dozens of times. Because spot prices generally don't change much in a short period of time, if leveraged trading is not allowed, even if we can look at the trend of the spot, the final profit will not be great, in other words, it will not be very exciting. And if you add dozens of times of leverage, once investors can see the trend of spot ups and downs, act decisively and stop losses in time, the income may indeed be quite rich. If the principal is sufficient, a transaction can indeed make a profit of hundreds of thousands and a profit of tens of percent.
