I agree with the idea that Warren has been wrong on a few things. However, he has done spectacularly well based on his convictions and rules for investing. Better than any of us goofs in a chatroom! He doesn't invest in things he does not know about. This is not to say that he won't change his mind. Bitcoin and crypto is hard to understand. And with his record of investments, he doesn't have to learn about or be right about crypto.

He once said he didn't like technology, yet he recently invested huge into AAPL.
Another fellow who doesn't like it, or understand it is Peter Schiff. He predicted the 2008 recession. See his comments here on the Joe Rogan podcast. The part about crypto is at the end of the podcast.

He does have some thoughts that do have merit. I can see both sides of this debate, and it is good to have an open mind. We may be wrong about crypto when all is said and done, and Warren and Peter may be right. No-one can predict the future. But I am betting on bitcoin! Good post!
