Am I able to change the currency shown on the site and set the one of my country?
Yes, you could easily change the currency from the admin panel and the Payments->Settings page
and set the currency of your country you wish.
If you need help when doing that or have any other questions or
remarks during your site configuration, you are always welcome
to contact our support team and we'll do our best to help you as part of the free technical support we provide.
