In the field of investment, the principle of "buy low and sell high" is almost universally known, but when the market truly faces a fall, investors who can maintain a calm mindset are extremely rare. In fact, the emotional fluctuations you can endure directly determine the profit margin you can achieve. During market fluctuations, those investors who can control their fear and greed often seize opportunities and make rational decisions amidst the chaos. This is especially magnified in high fluctuation markets like Crypto Assets, where the importance of psychological resilience is even greater. The ability to manage emotions not only affects short-term trading results but is also a key factor for long-term investment success. Learning to stay calm during market panic and to remain rational during market euphoria may be the most valuable skill for investors.
