The altcoins are a bit immovable
Since Bitcoin does not fall when it falls, it means that the altcoins have reached a relative bottom. Bitcoin cannot fall all the time and will rebound. When Bitcoin rebounds, the altcoins will rebound more.
The correct strategy is:
You may feel scared when buying, but this is the right time.
You may feel reluctant when selling, but this is a rational choice.
If you can go against the trend, open a position during a pullback, and buy boldly during a panic decline, you will have an advantage over most people.
