No — at least, not yet! Although Wix Payments supports six different currencies, you have to choose one for your store. You can’t sell in multiple currencies at once, which makes life difficult for multilingual stores.
The currency of your Wix store is based on your bank account’s location (for individual accounts), or the country of your business’ registration (for business accounts). So if your business is registered in the US, for example, then you can only sell in USD.
