Why you are saying it!!?
Because he don't have any belief on bitcoin, many people are not agreeing because bitcoin has price variation from time to time. So many people don't have interest towards it. Even when the price of bitcoin goes down again so much fud will start again on bitcoin.
Saying that bitcoin is not the future money doesn't mean they don't believe in it, seeing people say this about bitcoin only shows
that bitcoin is not yet ready to become an alternate to Dollar, people will start seeing the possibility of bitcoin becoming an alternate to Dollar if the existing problems are solved.
