How can I make a transfer in another currency?

When you create a new transfer in the application, you can select a currency from a list of supported currencies. 

Transfers -> Select a contact or create a new one -> On the right side of the amount field, you can change the currency. 

You can send transfers in any of 16 available currencies straight from your account. Amount of the transfer will be automatically converted to the currency of the account from which the transfer is made.
