Am one of the people who got affected by this worst decision . Though this decision sounds good for many , it comes worse as time goes . Black money holders had already found as many possible ways to convert that into white . One such way is , getting a demand draft for 49000 without proof which has 3months validity and gets the 49k exchanged to white cash in month or two . One big thing is no one is going to give u change for 2k easily expecting nothing return. Further when someone has 50 crores black money with 1000 inr denominations , when it takes two rooms to store that amount , it takes just a single room for storage saving them from many issues . May be the 2k note is the biggest worst decision by Modi . There were chances that he might be having issues to store his blackmoney in large amounts in smaller 500 n 1k denominations . so perhaps it might be move for his own purpose(this may sound silly, but this is right from one end) .  Modi announced he was a tea seller in the beginning which is completely fake as of many sources . I suspect his decision is a future fraudster and might be bigger hidden cause behind this decision .
