How to Add Multiple Currencies to Your Shopify Store
Once in the Shopify sdmin, click on Settings in the bottom left-hand corner. Then, click on Payments.

At the top right of the page, click on Manage. Scroll down to Currencies and click on Add Currencies.

From there, check off all of the currencies that you’d like to add and click Add Currencies and then Save.

Now that you’ve added the new currencies, refresh your website to see if the currency toggle shows up in the top navigation. If it doesn’t, you’ll have to turn it on in the theme settings. In the left-hand admin menu, click on Online Store. Then, click on the Customize button. From here, the steps you take may depend on your theme. For the theme we’re using today, Warehouse, we went to Header under Sections and checked off the Currency Selector check box.

After clicking Save, we refreshed the site and now see the currency options in the top navigation.

BONUS: If you’re not sure about which currencies to add, you can view your top countries and their web traffic by clicking on Analytics in the left-hand admin navigation. There is a section on your dashboard called “Online store sessions by location”. Find that and click on View Report to see more in-depth details.
If you plan on using or are already using other avenues to bring in customers (ie, Facebook or Pinterest), you’ll want to check your insights there as well to see which countries your followers are from.
