Many people incur losses because they have small positions when the price of the coin rises and large positions when it falls, which stems from poor trading habits.

When buying rising coins, the initial position is small, and as the price rises, the position is continually increased. When the price pulls back, it becomes the maximum position, causing early profits to potentially be lost in the pullback.

Although it is occasionally possible to correctly add to the position, in the long run, this trading habit can lead to significant losses. To avoid this situation, we should develop the habit of 'selling high and buying low' to prevent chasing after highs and panic selling.
