#M In the afternoon, everything was fine, making a profit of 150%, all pulled back, pumped a hand at an average price, and left after deducting the handling fee.

Then I made a few more moves with a pump and pullback, each time taking 30-50%, and I was satisfied with the small gains. Successfully flipped the account.
In addition, the handling fee was also refunded over 20u today, and things are getting better. The position is about 125u, taking it slow and steady. Even if I lose, I won't get too anxious.
