If you are concerned about the loss that appears as the coins (tokens) you hold decline, you must sell some of them to stabilize your psychological state.
If not, you should be careful because your psychological state may become very unstable and you may suddenly do something strange.
The coin market is expected to maintain an upward trend until the end of 2025, so you should consider a trading strategy such as lowering the average purchase price by adjusting the investment ratio or increasing the number of coins (tokens) corresponding to the profit.
