Buddy, when the economy tanks and you default on payments, the currency will hit a bottomless pit. You may even have a situation that one million PKR will equal just One USD.Today's rate:
PKR : XE: Convert USD/PKR. United States Dollar to Pakistan Rupee
INR : XE: Convert USD/INR. United States Dollar to India Rupee
Nearly half the value of INR. If it is to become useless as you say, what exactly are the rates we are looking at ?
