At the top left of your dashboard, click Manage Account.
The next screen shows a list of all accounts currently displayed on your dashboard. The crypto accounts are default, and cannot be added or hidden.
Click on the fiat currency you wish to add to your dashboard. Alternatively, click Hide to remove them from the dashboard. Removal is only visual - once added, a currency account cannot be removed from your QUOINEX account.
Click Done to go back to your dashboard.
Any added currencies will appear on top.
