In this big dump, we see the most true side of human nature - greed and fear. When the price pumps, people are often prone to blind optimism, thinking that they can easily obtain high returns. But when the price falls, they will be in extreme panic and eager to dump their assets. This psychological change not only exacerbates the volatility of the market, but also causes many investors to pay a painful price. In fact, in any investment field, maintaining a calm and rational mindset is the key to success.
