I would put it this way. With all my respect to W.B. (as a matter of fact, he is my top investing role model), he turns 90 pretty soon. He has experienced some interesting live events, so he reflects them in his opinions though indirectly. In the past, things did not move that fast. But. Say last two decades, things have kind of rapidly got faster, like instant payments or digital asset, both secured by cryptocurrencies. Sometimes, old generation is a bit sceptical to new things like the crypto in this case. Therefore, I am totally OK that the Oracle of Omaha rejects crypto.
