I definitely agree on the potential for growth, because of the simple fact that the number of people familiar with cryptocurrencies is growing exponentially. It is only logical to conclude that the more people become aware of this relatively new market, the more financial power will flow into it.
As a practical example, I'm focused on the upcoming onG.social ICO this month. While I'm actively researching it, none of my friends have even heard about ICO and have a vague idea of crypto. That's why at this point services like onG.social won't get as much attention as Facebook does, but it's possible that it is only a matter of time, until they start to catch up. And the diagrams in this article would begin to reflect that. : )
