Absolutely not a hindsight analysis, this wave of sushi turnover, selling at relatively high positions, and the buy orders placed at relatively low positions. Otherwise, spot profits would have to be given back in a month. This wave of correction has been warned about since 1-9 days ago, specifically on the 1st, 3rd, and 5th, with multiple reminders about the risks in the group. When the market is optimistic and everyone believes it will continue to rise, you need to understand the principle that others are greedy while I am fearful, and make the decision to withdraw from the current surge. Use a long-term strategy (regardless of bull or bear markets) that can grow steadily; although it cannot guarantee that everything is sold at the highest point for maximum profit, it can ensure that most of the profit is secured first. During a waterfall decline, you can still have bullets to buy the dip and lower the average price.
