The jury is still out on 2015 and Bitcoin more generally, but it seems that if trends like those depicted in the graphic continue, “mass adoption” could be a reality within our lifetime.

Others define it more as a situation wherein most transactions are handled by the Bitcoin network but very few actually come into contact with bitcoins.
