The idea of bitcoin is absurd for them, they think that it will never work nor gain value. Several years to the present and I think all of us will agree that bitcoin has drastically gained value as well as popularity. People are beginning to recognize bitcoin for what it is, a decentralized coin that can be used by anyone as long as they have access to the digital platform. I guess people like that are skeptical of bitcoin because of its volatility, unlike Fiat which is stable and highly accessible to the public.
