Teach you how to distinguish between good coins and junk coins?

It's very simple. When the Bitcoin price crashes, you can tell by looking at the degree of pullback of other coins. No matter how much it has risen before, if the pullback is large, it means it is still a junk coin. You must choose a value coin with a strong market maker background or ecological support!

Less rise, more pullback, junk

More rise, more pullback, cut leeks

Less rise, less pullback, inferior

More rise, less pullback, high quality
