During a bull market correction, focus on two trends in altcoins:

1. Currencies that have corrected and may reach a bottom: they have risen sharply before and may form a bottom after the correction. If they successfully establish a bottom, they are expected to rise again.

2. Currencies that remain strong during corrections: Even if the market corrects, these currencies still perform strongly and usually have strong financial support or market recognition.

In addition, focus on the potential currencies formed at the bottom and the currencies that continue to be strong. These are coins worth buying and holding.
