I haven't updated for a few days, I will continue today.
There is 2685 RMB left in the account. During this period, I transferred more than 3000 RMB to play local dog, and the return path: -47681 RMB.
The current situation of Bitcoin is unclear, so I will wait and see for the time being, and will not trade mainstream currencies. Now I only hold a long position in ULTI, which looks very strong, and the fee rate is also negative, so I will continue to hold it.
