The most frustrating things about investing in the crypto world are these few issues. During critical moments of market decline, you just happen to have no money to buy the dip, watching opportunities slip away helplessly. Conversely, after finally gathering the courage to buy the dip, before the market can soar, you find yourself unable to hold on and sell early. What's even more heartbreaking is that when a certain coin is really about to take off, you realize you don't have enough chips, and can only watch your wealth slip away. Many people have probably experienced this feeling. The market always tests human nature and constantly reminds us how to better seize opportunities.
