From the Home Screen, tap the cog icon in the bottom right corner to open the settings page. Next tap the ‘Native currency’ button:
This will bring up a list of currencies from which you can select one to be set as the native currency for your account:
On the home page your total balance will now be displayed in this currency.
You can still tap on the total balance button and switch between displaying the funds you hold in specific currencies.
The currency which you have set as your native currency will be automatically preselected when sending/requesting funds to/from another Bottlepay user.
The currency in any transaction can be changed easily by clicking the downward facing arrow next to the transaction amount.
