Today I brushed 8000, with a loss of 3.6, which is 1.6 more than yesterday. I realized that I need to brush at the right time with the right coin, rather than just deciding to brush at 8:30 and expecting the market to cooperate. High losses often come from price fluctuations; for example, this koge was actually not suitable for brushing in the morning due to significant price volatility. The best time to brush is when its trend resembles the previous weaving pattern, minimizing losses.
