How to set 'Allowed Currencies' for each store programmatically in Magento2.
Options in Admin Panel are placed here:
System -> Configuration -> General -> Currency Setup
Also I'm not sure where exactly these informations are stored in magento database.
You just need to Select your store from top:
Then set your allowed currency for your current store and hit on save.
You can see the selected values in database -> 'core_config_data'. It would be saved on the following path: for allowed currencies: currency/options/allow
for base currency: currency/options/base
for default currency: currency/options/default
cheers !!
