How to tell if a man has brains?

There is a type of man who, even if you give him a code, he won't look at it; you have to give him a seed.

And there is another type of man who, no matter what picture of a code you give him, can find the code you want on the internet.
He is just like Kill Bill @wolfyxbt.

The lives of these two types of men are completely different, and this is also the difference between retail investors and KOLs.
