A day in the crypto world is like a year in human life. Rapid rises and falls temper the mind, while news noise disrupts judgment. Most people lose due to greed and impatience, chasing highs and getting trapped, selling at the bottom. Leverage is a double-edged sword, and many altcoins are traps. Only through bull and bear markets do you understand: don't gamble your life savings, don't greedily chase the last penny, maintain risk control, live steadily, and this is the long-term way.
