Knowledge and action are not one. A few days ago, I monitored a smart investor. After observing for a few days, I found that whatever he bought ended up with losses. He bought ten or more in one day, and his recent win rate was very low, so I didn't follow him. As a result, he bought ban at the bottom yesterday. The average price was 0.000031. Then today, ban did this. Of course, he sold it at night. He had almost sold it all yesterday. He only made 10 times. It can be said that if I had followed him with 30u, it would be worth 60000u today. It's that crazy.
