I doubt if Buffet misses the opportunity to make more money from crypto because, as an entrepreneur and one of the richest people, he will get advice from people around him about crypto and invest in crypto secretly. Maybe Elon can be one richest people in crypto but who knows, the title will change in the next year as with growing of the crypto, that will attract more richest people to invest in crypto. They do not want to be late to decide to invest in crypto, especially they already saw what happened to many people who already invest in crypto.
I don't want to speculate much about this considering that until now, especially in the media, he still strongly rejects everything related to bitcoin.
but it does not rule out the possibility that this can be justified because we do not know for sure about it because the one who knows it is of course he himself.
but what is certain is that everyone has secrets and buffet must have them regardless of whether he has or not I think what he said about bitcoin and crypto could be a spice to make something.
