July is over. I would like to express my sincere gratitude to our Leek Light Teacher Fat Cat. Since I started to follow him and learn his thoughts and knowledge, I have been able to control my blind opening of positions and get rid of the ranks of leeks. The most useful are the Kennett indicator and Coinglass app recommended by Brother Mao. Finally, I would like to share my two favorite sayings of Brother Mao: Selling for a long time and not losing money in short positions is a profit.
