There is a lot of billionaire and most of them do really see the technology of Bitcoin to be of great help in the near future but we all know that every individual has their own point of view the reason not all of them agrees to that. Bitcoin might dump but there are a lot of them that supports Bitcoin so we do not need to worry.
