Someone can run campaign to promote it. Then we'll see the price going up due to its increased adoption!
first of all why that someone isn't you? you can't always expect others to do everything, bitcoin is decentralized so it is up to all of the users.
second of all promote and say what? invest in bitcoin and go to the moon? NEVER, that is not good at all. we don't need more speculators. the only promotion bitcoin needs is new merchants, new services and businesses to start adopting bitcoin. when you see Amazon accepting bitcoin you will start using it.
Yeah you're right, how can we promote bitcoin for people when bitcoin itself is still not accepted in many places and hasn't been used by many merchants. And so promoting bitcoin will somehow have the opposite results. When people hear fancy things about bitcoin on ads, they will start to find out more about it and want to use it, but when they realise that even their local market doesn't know what it is then bitcoin will frustrate them and to some points, they will give up on it.
