Buying altcoins, I have always had a principle: Leading Thoughts
Don’t use the theory of catching up. Leaders can always be strong, and they can become stronger, with a significant sucking effect. In the later stages, it’s the garbage coins that are catching up. Another method is to observe which altcoins are the most resilient during each pullback. You can see that in this rebound, strong altcoins have already returned to the peak before the waterfall, while weak ones have not returned at all. This is like choosing the wrong coin, as if marrying the wrong man; even if you’re trying to buy at the bottom, the reasoning is the same. If you don’t know what to buy, just buy the leaders during their pullbacks.
