I don't really see a point of those type of people trying to use Bitcoin to purchase whatever they want since they're already rich. Bitcoin does not have any weight to it when showing somebody the amount of coins they would have, if they show how many paper money that they have then people will get jealous and is more than likely to be controlled by the holder.
They have an own business to have money so they didn't need bitcoin to become more succesaful. Maybe they will be build an ICO Campaign to become more successful.
