The dollar is my basic currency.
Doesn't paypal support the pound and euro?
I like Rupee, all most of the trades are with dollars.
€ for sure. Because I live in Europe, and € can be used on many countries.
But still I use mostly US$, in the internet. And all my internet money making calculations are in US$.
Living here in America, I tend to favor the dollar.
Why? Well because I certainly can't pay for goods and services in the US with something like Yen!
I do, however, collect foreign currency! (Not for profit, just for fun.)
