如何在产品形式magento 2中为所有货币（所有货币的不同价格）添加价格输入字段

How can i add price input field for all currency (different price for all currency ) in product form magento 2

You don't have to manually add price for each and every currency. You can add the price which is for base currency for EG (USA). Now you can allow which currency you want for your magento store.

Go to Stores > Configure > General > Currency Setup section from the main admin panel. Here, you will be able to change the Base and Default currencies for your Store from the list.

Now form Stores > Currency Rates you can choose your import service and import currency exchange rates of currency.

In Frontend You will see the currency switcher visible when there are more then one currency allowed in your store.

Thats it you can now enjoy Magento Magic.
