KOCHI: After the ban on 1000 and 500 notes, so many mediators are there for changing the banned notes. They offer the newly issued 2000 notes and the standing 100 notes instead of 1000 and 500 notes. Even in the village centres we can see such mediators on commission basis. Businessmen , politicians, bankers and the mediators in the real estate sector are there in this scenario. The successful stories are rare but a new group of gamblers emerged after 8th November. This indicates that the government should be more vigilant to avoid malpractices in the money market.
