You can as of now not change the currency once your account has been created and your country has been set, regardless if the moderators change your set country in your details.
We are working on making it possible to change your currency on your account, but it is an advanced fix due to technical payment hurdles. We do ask for your patience until this is fixed.
In individual cases, we do send another preferable currency when sending through manual banking.
We do support the currencies EUR, USD, GBP, SEK, CAD, and AUD. Please note that we are not allowed to send USD to a bank that is located/operates outside of the United States of America. We will make sure to convert and send your winnings in the best suitable currency if you have the currency set to USD on your wallet and have a bank account outside of the USA. Make sure that you have a bank account that accepts some of these currencies and makes sure to submit a request if you have any questions regarding currency.
