I see your point, but I stick with mine because while there may be groups who congregate around common interest, social media congregates around influencers.
Additionally I think cryptocurrency and blockchain are very complex, thus groups congregating around it seem much smaller then groups congregating around influencers.
One inlfuencer with 21 million followers encompasses all people in cryptocurrency by some estimates.
But I get your point, and it may be a path towards growth, but not mass adoption.
When I look at HIve and it's lack of mass adoption, it may an illustration of the limits of growth fueled entireluy by common interest.
I suspect greed, envy, lust, hate and other primal emotions are the driving force for mass adoption and until we generate that appeal we will languish as a community of small numbers.
