I think cryptocurrency got a push in the right direction when the Indian government demonetized high denomination notes in November last year. Many "discovered" Bitcoin at the time and it became popular once people got to know what it really means.

With a population of 1.2 billion and rising, India would be poised to become the largest user of cryptocurrencies given enough exposure and awareness.

Same goes for Steemit's popularity in India as a place for blogging and getting rewarded for it.
