The characteristics of the cryptocurrency market are such, especially with low market cap altcoins. Once they start to rise, they often have strong persistence and rarely provide obvious opportunities for a clear dip to buy the bottom. If you think there is a good time to buy the dip, it is very likely that the market has already peaked.
This passage mainly wants to express two points:
1. Learn to chase the rise: If you want to keep up with the rhythm, you must decisively follow in during the upward trend, daring to 'jump on the train', rather than waiting to buy the bottom during a sharp decline, because for the vast majority of altcoins, a sharp drop often means that the market has ended.
2. Stop buying the dip in altcoins: For 99% of altcoins, the market basically ends after a sharp decline, so that's it, don't cling to trying to buy the bottom anymore.
