Why should we care? The man made his money outset of cryptocurrency therefore he is not an authority here. Just like Warren Buffet these people got their success on their own terms and they should be respected for that. Now, people usually ask these people on what they can say about Bitcoin and they are looking Bitcoin at their own lenses...their own opinion and ideas and we should give these people the space that they deserved. But to think that they should be influencing the movement of Bitcoin that can already be far-fetched.
