Today I originally planned to brush 8000, but with guests at home constantly chatting, I unknowingly brushed 10500. After a bit of determination, I brushed enough to reach 16400, that's it. Today I brushed ZKJ, totaling 16400, with a loss of 4.2u. In the past, I brushed confusedly at the exchange without calculating the losses; sometimes I ended up losing dozens of u, with the most I lost at once being 150u, damn! Since I changed wallets, it's much better.
