Teach everyone how to distinguish between good coins and bad coins?

It's very simple, when Bitcoin crashes, you can see the degree of pullback of other coins to know. No matter how much it rose before, if the pullback is large, it means it also can't be held for the long term. You must choose valuable coins with strong backing or ecological support!

Rises little, pulls back a lot, garbage

Rises a lot, pulls back a lot, cutting leeks

Rises little, pulls back little, inferior

Rises a lot, pulls back little, high quality

Take a look at what type your coins belong to?
