You can change the currency of your own items in your profile settings. The default currency will be the same as your phone settings. If you wish to change the currency, follow the below steps:
- Tap Profile at the bottom right hand side of the screen (on Android, you find it in the main menu)
- Scroll down and choose 'Settings'
- Click on 'Currency' and choose any of the available currencies
This change will apply only to new items. Your previous items on your account will remain in the currency as before.
