Critically Analyse the role of Demonestization of currency in India. Is it going to stop the black money?

Though it is argued that it will curb black money to some extent  but it has wide ranging impacts on economy because our economy is dependent on the cash as less than half of the population uses banking system for monetary transactions.
It has impacted trade and consumption sectors.The  Real estate sector will be affected badly,the poor suffer a lot because they are often the daily wagers etc.
