There is a big difference between volatile markets and markets like stock market.
For example, a good hedge fund manager called Peter Lynch wrote books about how to invest, it wasn't a pretty book and it was basically a regular person trying to be a writer so you read a lot of needless Jibber jabber along the way but if you shorten the book to summarize it than you get something like "value investing" that Graham and Buffett have been doing for years, he just made it easier to understand and gave you a recipe.
I have followed that rule on the stock market for the past 9 years and have been making about 16%-20% profits yearly ever since than.
Moreover, you can't apply that to crypto since it is incredibly volatile and there are no investors and recipe like that for it so far. Hence there is no correlation that you can draw between the two.
