In just a few minutes, I made $300 profit, but unfortunately, I couldn't hold onto it. In the end, I still lost my principal. A few minutes? 300 to over 2000 RMB, which is equivalent to my half-month salary. Sigh, it's better to just stick to spot trading; ordinary people can't afford to lose like this. If the direction is wrong, I can also lose half a month's salary in just a few minutes.
