Paypal is now setting new currency options for account. So if you are from outside US then you have to setup primary currency. For example, you get payout in USD and it will convert into your local currency if you don't set primary currency. So anyone sending the currency in USD it will automatically convert to local unless you specify.
This is happening to many users outside US. So go to settings > withdrawls> currency setup. This page may be different for you as not all paypal account are same. And we have localized setup.
