Yesterday, my profits had already doubled, and I took my profits. However, in the evening, with nothing to do, I decided to do some shorting on a coin, thinking the market was too hot. Who knew that the market wasn't over for the day and I quickly lost over 100%. There was no way out, so I set a stop loss, giving back the profits, and ended up with a loss!

Remember not to make impulsive trades; if you do, you must conduct thorough research, find the right entry points, and set stop loss and take profit levels.
@Boastful please pay tax, I remember I used to collect Teacher Guo's quotes, hope to find them again. Thank you Teacher Guo.
