When the price of the coin drops, many people's first reaction is to avoid risk and wait and see. But experienced traders have a different idea: this is precisely a signal that opportunity is coming. When market sentiment is pessimistic and prices are falling, it is actually the golden time to accumulate positions. Instead of hiding on the sidelines, it's better to take the initiative to buy the dip. The logic behind this is actually very simple—when others are fearful, we are greedy; when others are greedy, we are fearful. Whether you can grasp this rhythm largely determines the returns of your investment.
