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 know if Buffet takes advice from anyone. He is someone who gives the advice. And as far as I know, he still refuses to endorse cryptocurrency. He is in his 90s and is unable to understand the technology related to cryptocurrency. Anyway, at this age, he will be more concerned about the preservation of his wealth rather than increasing it. And for doing that, he needs a stable fiat economy. Alternatives such as cryptocurrency pose a danger for that status quo. Anyway, his time is over. He made his profits during the last century and he should be proud of that. If he was making the investments now, then I am sure that he won't be as successful as he was earlier.
We do not know his mind, but if someone has more wealth than the other, he will want to get more because that is human nature. We do not want others can have wealth like us, even closer to us so we will try to increase the wealth in many ways. Yes, he is in the 90s, but that does not stop him from having a passion for getting more money. Maybe he does not understand but he has an advisor's finance who will advise the opportunity in crypto and he did that without us knowing. We admit that he made his profits during the last century but that does not mean he will not explore a new thing that he can give to his descendants.
Buffet is old but his brain is not old and smart people like him can easily understand Bitcoin and choose not to endorse or make an announcement about it cause it may influence the decision of people that sees him as god just like we see Elon Musk doing through his tweet. However, if he makes an announcement about people that invested in his company may choose Bitcoin over it. Therefore, he believes he invested secretly in Bitcoin.
Having said that, I don't know where the OP gets the information about Elon to be the world richest man in the world but according to
Forbes Jeff Bezos is still the richest man alive.
Yes, it is better to invest secretly without anyone knowing than to announce to the public. It will make him get asked by the media and the media can easily compare with Elon or other richest people who already invest in bitcoin. Besides that, if Buffett announced that he has bitcoin, that can attract the government's attention or the authority to know more about how many bitcoins he had.
Forbes says Jeff Bezos is the richest man based on the fiat that he has and not bitcoin but maybe Elon has many bitcoin but if he does not sell his bitcoin, then it will not be the same if someone has much money like Jeff Bezos.
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.
We should let it be like that as Buffet does not tell about his interest in bitcoin and we only knew that Elon has bitcoin. Yes, everyone will have their secret that they do not want to tell the public, and that is their privacy. Sometimes, the media does not tell the truth because the media want to search for the publicity of the news to modify the real story just to get more attention from the public.
