The current account number of 20,000 is 26,000. Currently, eth has received about 2,200, and there are some other contracts. It is expected that the account will reach 30,000 in this wave.

Reflection: There are still some problems in the operation. I did not continue to roll up the position. I added a position once in the middle. I hesitated several times when I had the opportunity to add a position, and finally missed the position. I am still worried about profit retracement. There are certain problems with this mentality. The position is not a full position, and the principal is small. There is no profit after rolling the position ten times. It is still worthwhile to exchange for a larger profit.
