No one cares rats ass for Indian Rupee outside India, US dollar is accepted worldwide as a legal tender and reserve currency with 67% worldwide foreign exchange reserves held by major exporter countries.
US dont have to keep foreign exchange reserves since their own currency is the reserve currency of the world , a feat unmatched by any other country.
Lots of buggers will say Euro, but Europe lacks military might of USA and no one will risk a weaker power's currency to keep their reserves.
And to make payments, US simply prints dollar notes ! Its as easy for them.
Americans dont have to work like dogs into odd hours in an outsourcing industry for 14 hours to bring in foreign exchanges.
