Great article!
I would like to point out Government of India is not getting ride of cash at-least not as of now they are replacing 500 and 1000 INR bills. This move was to tackle the menace of fake currency coming in from neighboring counties (possible terror links) and to tackle tax evasion read black money/money laundering/corruption.

None the less people are optimistic it has been a huge learning curve for the general public and they are realizing the benefits of going cashless. There has been a massive surge in bitcoin exchange rates and in general Fintech community is bullish.
