The people that knows how Bitcoin works will not buy the lies because of the knowledge. But because of the fluctuation in rates/prices, it's easy to tell the lie because nobody wants to lose the money invested.
In my opinion, many see Bitcoin as gambling because of its volatility and I think these narratives need to be changed also I want to believe that Bitcoin is a threat to banks, with this, the banks will want to spread negative news to the government and citizens. The bank's concerns and fears aren't now but the future.
