$USDC This is a sad story:

1. Recently, the market has been bad, continuously declining, and the spot has directly trapped me; if I'm doomed, so be it. Out of sight, out of mind, so I haven't opened Binance in a long time.

2. I had almost given up on brushing for alpha, but suddenly heard that Binance had strengthened its risk control and banned many abnormal accounts (I've heard of many being mistakenly punished), thinking that finally Binance was doing something right.

3. So, with a sense of luck, I picked it up again to see if I could continue brushing. For two consecutive days, I brushed USDC/ZKJ - 33k tier, using the wallet while the price was rising, with a slippage of 0.01, in the PCS Hub pool, a single transaction fee of about 0.0080467u, 2+15 minutes, 500u, brushed it 66 times, and the total wear was over 3u, anyway, it was less than 4u.
