When Luna crashed, I used 200 dollars to buy 27 U, and I made a maximum profit of 2700 U, which is about over ten thousand dollars. It wasn't a full position because there were holding limits at that time. Each time it was a fixed amount, and I would save the profits!

This is part of my transaction records from that time. This was almost my highlight moment in the cryptocurrency world over the past two to three years!

The strategy is quite simple. At that time, trading activity was very high. On average, each 1-minute K-line moved a few points up and down. I would wait for the K-line to drop after a minute. If it felt like it wasn't going to drop any further, I would immediately go long. Then, when it rose to the point where it couldn't rise anymore, I would quickly close the position and go short! The trades were very fast; sometimes I could make two trades in a minute!

There was also a fee issue. At that time, since a 1-minute K-line only moved a few points, the fees could basically be ignored!

However, until now, I haven't used this method again because I haven't seen such market conditions since!
