He himself said he knows nothing about crypto. But he does know it will end badly. I don't get why CNBC asks him about crypto currency when he admits he knows nothing about crypto. So basically the whole interview is useless, of course it will end badly for some. There will be people who make tons of money and others will lose, that is how it works.
Spot on. Here are the silly old duffer's verbatim quotes:
"In terms of cryptocurrencies, generally, I can say almost with certainty that they will come to a bad ending."
But then, this:
"I get into enough trouble with things I think I know something about. Why in the world should I take a long or short position in something I don't know anything about?"
Every time he opines about cryptocurrencies, I lose a little more respect for him.
