We have all experienced that kind of sleepless night during a sharp drop, doubting whether our judgment was wrong while still unwilling to miss out on the rebound. But you must understand that emotions are temporary, while understanding is permanent. When you truly grasp a project's logic, development path, and actual value, you won't easily waver because of short-term price fluctuations. Bottom fishing does not require you to hit the lowest point perfectly; rather, it allows you to gradually establish a cost advantage amidst chaos. In the short term, you may feel uncomfortable; in the long term, you will thank yourself for having the courage to buy today.
