He really doesn't understand tech.
He is trying to stay away from things he doesn't understand.
He obviously fears bitcoin, quite likely because he knows he can't understand it.
He seam to always made his buck the same way, like he is still doing now, and bitcoin threatens the way he learned to do business, so no wonders there why he is against it.
I remember watching his speech where he was proud to say how he likes longterm businesses that have the same brand advantage and certain prestige that doesnt fade out, too bad he didnt realise how bitcoin is the next one to dominate the market, increasing strenght with every passing year.
Its time for changes, and all that wealth he accumulated over the years is going to be worth a lot less soon enough, leave the old man in the past where he belongs.
cheers
He is a total dinosaur of finances like it has been said before, he doesn't see the paradigm shit coming, or indeed he sees it and sees it as something that can damage his classic-style assets since once Bitcoin goes global it will disturb things at unseen levels.
