When the bull market pulls back, focus on two types of altcoins:
1. Currencies that pull back and may bottom out: They have risen sharply before, and may form a bottom after the pullback. If they successfully bottom out, they are expected to rise again.
2. Currencies that remain strong during the pullback: Even if the market pulls back, these currencies are still strong, usually with strong financial support or market recognition.
In addition, focus on the potential currencies that form the bottom and the currencies that continue to be strong.
