Some wealthy people have expressed their disdain towards Bitcoin. They believe Bitcoin is a scam or Ponzi scheme backed by nothing. Figures like Warren Buffet, and even Donald Trump himself believe Bitcoin is a sham. I'm surprised to see this, since Bitcoin brings many profit opportunities to its "hodlers". For some reason, millionaires (or billionaires) hate Bitcoin. They usually support Gold and Fiat, not wanting to try something new like crypto/Blockchain tech. Justin Sun tried to convince Warren Buffet to get into crypto a while ago, only to find that his efforts were in vain.
Thoughts?

They don't want to join Bitcoin, but they are afraid that if people get rich because of bitcoin, some of them also don't know about technology. For a trump he fears Bitcoin will go big and affect the value of the usd. However, no matter how much they hate bitcoin, they can't prohibit the existence of bitcoin at this time
