100% demonetization in India.

Entire paper currency must be banned.

Demonetize entire cash currency. Assuming there is an N number of rupee cash currency in the market. Within 1 hour transfer, N/130 crores amount to all the Aadhaar enabled accounts of 130 crore Indians. After this announce that cash is completely invalid and everybody must use their debit card/ e-wallets. This will dilute black money and bad politics. This will avoid ATM maintenance. More tax money. In case of special cases where some people might have withdrawn money for some emergency or special purposes they can call their bank customer care and they can assist them based on their recent transaction history. GOD bless All.
