We only need ordinary people like you and me to start using Bitcoin in any way each person would like.
People aren't really "using" bitcoin and probably never will. As a currency it sucks, but long-term holding as a store of value is where it excels. Everyone should be aiming to just hold a as much as they can afford for as long as possible.
For now, using it as payment method is not rampant so to speak because of considerations such as high tx fees, duration and convenience.Most are just holding it for the very reason of getting high profits.
