How do I change the store currency?

In order to change the store currency we need to publish the store configuration file:
php artisan vendor:publish --tag aero::store-config
Then locate the 
configurations section of the published 
config/aero/store.php file and update the 
currency_code value of the active store configuration.
Ensure the new 
currency_code exists in the 
currencies database table of the store.
