Alpha, not even the dogs are brushing! If I brush, the dogs don't brush, I earn 3u by brushing 14 levels.
Brushed 14 levels with a trading volume of 18,000, earning 3u.
The major loss in points comes from a drop in coin prices; when the coin prices are stable, the loss per transaction is minimal. Therefore, my method of earning 2u is to brush when conditions are normal and stable; a small loss doesn't matter. A slippage of 0.08 can still be executed.
The first 8 back-and-forth normal brushing incurred a loss of 4u, and the last transaction earned 7u, so I can play again today.
