The two common situations where people lose money are:
1. The market value is too high, and small investors feel it's hard to rise, so they earn little, then go for PvP with small coins, and eventually lose their principal quickly.
2. Fear of a downward trend leading to zero, then selling at a loss, repeating this operation, and ultimately losing all their principal through selling at a loss.
How to get out of this predicament:
The core issue is: reasonable allocation of funds.
Through a stable winning rate, continuously compound and accumulate funds, and patiently wait for significant opportunities to appear!
