The characteristics of the bull market altcoin season are as follows:

In the first stage, the coins that rise are those you do not hold, and possibly ones you have never bought before.

In the second stage, the coins that rise are those you once held but did not hold onto.

In the third stage, when you switch positions to chase the rise, the originally strong coins pull back and trap you, while the coins you sold rise significantly.

This "chasing highs and selling lows" scenario is common in the bull market altcoin season. It is important to remain patient and calm, and not to be led by market emotions.
