Someone can run campaign to promote it. Then we'll see the price going up due to its increased adoption!
It was going for naturally. Like this place maybe. But honestly all of the cryptocurrency was linking into bitcoin and if the someone was wanna joining in there and It will always try for advertising it. It won't a company or something like that but just let it growth.
The bitcoin already has a lot of the advertised source.

Yes naturally and in some of my posts, its effective if its a word of the mouth or group community effort, like what we are doing now. Also, by encouraging our friends to used bitcoin,educating them and even giving them gifts in bitcoin
