1. "A sharp decline is the touchstone for quality coins." If the market crashes and your coin only drops slightly, it clearly indicates that the market maker is protecting the price, refusing to let it fall. Therefore, such coins can be held with confidence, as there will be rewards.

2. If a beginner doesn’t know how to buy or sell, the simplest and most direct method is to hold during the 5-day moving average for short-term trades; if it breaks below the 5-day line, sell. For mid-term trades, hold when above the 20-day moving average; if it breaks below the 20-day line, exit. There are many methods, but the best one is the one that suits you. The difficulty in trading isn’t the lack of methods, but the execution. Persistently and mindlessly repeating one method works for over 90% of people. The road is simple. $USDC
