Base currency XCG during company creation not listed

I am testing erpnext for our company

We live on Curacao and our currency is XCG abbreviation: Cg

https://en.wikipedia.org/wiki/Caribbean_guilder

During the company creating this currency is not an option, and i cannot change it afterwards !

When i select USD during creation, the accounting will stay USD

I can add XCG afterwards but the base is still USD

Even when i change it in Global Defaults en system settings, the base is still USD.

It it possible to add this currency before creating the company ?

I am using this page as a guide for the installation:
