4. Those who do not stop loss when they are trapped.

5. Those who frequently cover their positions blindly at the beginning of a downward trend.

6. Those who hold the currency for a short time.

7. Those who chase after the rise and cut when it falls.

8. Those who frequently change currencies.

9. Those who hold a large number of currencies.

10. Those who listen to news everywhere.

11. Those who are stubborn and self-satisfied.

12. Those who lack courage.

13. Those who dare not buy at the bottom and are unwilling to sell at the top.
