At present, we are supporting the U.S. Dollar, Euros and British Pounds.
In order to set your default currency, click on 'Settings' in the menu on the left hand side of your 'Dashboard'. Click on 'Payments' to select the default currency.
You can chance the currency for individual videos during video upload. Just select the currency from the currency selector.
If you want to sell a video in different currencies, we suggest that you 'Make a copy' of the video. On that video you can edit the payment settings.
We are building features to support other currencies soon.
