Dear Prime Minister, great step and the bravest step since independence. Instead of bringing of 500 notes again, please make it mandatory for transaction over ten thousand rupees only in digital method for stockist, bulk-seller and companies as these are the people having highest amount of black money due to monetary dealings. gradually it will percolate to lower level. Lastly please think of golgappawala, and other street food sellers who earn more than salaried person but do not pay tax.
