The bull market altcoin season has the following characteristics:
In the first phase, the coins that rise are those you do not hold, and possibly those you have never bought.
In the second phase, the coins that rise are those you once held but did not hold onto strongly.
In the third phase, 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 rises and selling dips" situation is common in the bull market altcoin season, so it is essential to remain patient and calm, and not let market emotions dominate.
