Who cares about Warren Buffet? He made money with Berkshire only because he was lucky. I am sure that his IQ is much lower than that of an average investor. And we can expect similar statements from low IQ people.
You can say a lot things about Warren Buffet, you can hate him or love him but for the one of richest man on the earth you can't say that he is idiot with lower iQ or just lucky.
He invested very wisely over very long period of time and a lot people now trying to learn from him and copy his method.
He probably don't understand bitcoin much but this don't change the fact that in most cases he made good financial decision.
