Warren is good and his comfort zone is traditional investing into companies. That is the skill he has learned his whole life and this is why he believes it is still better because it is familiar territory for him. I don't blame him because he has a lot of money and he doesn't need to put it all in high risk investments such as bitcoin.

For him it is better to continue to do what he knows the best because that is what he is doing for a long time and has experience in.
