Buffet is too old for crypto. If he want to just buy gold and not invest in btc then it his own right
It's not that he's too old. Buffett is a very smart man and he just doesn't see it having any long-term value--plus his shareholders at Berkshire Hathaway would probably revolt if he did get into crypto.
Maybe he sees its long term value but it's too long for him.
We will gradually move from paper to electronic money and possibly from there into more mainstream crypto but it's going to take many years before it happens and the future can be volatile. Buffett will be long gone by then. Old people prefer stability.
