The people who truly make big money must have great courage and bravery, meaning you recognize the market trend accurately and aggressively go all-in. For example, during a recent sharp decline, the drop was very fierce, and many people didn't have time to react; they chased short positions during the decline. But because the fall was so intense, after the shorts were exhausted, trading volume would decrease. Many people thought the bottom was in and started to buy the dip, leading to a rebound. When this rebound reaches a certain level, it forces short sellers to cover, resulting in a sharp spike. At this point, the market becomes unstable, and if you can't judge correctly and enter the market, you can be easily wiped out. The little courage you have left is also consumed, and it can no longer be called great bravery.
