multi-currency: shows different currencies according to the product, Magento

I manage a store and we have products from multiple suppliers. Some sellers are selling in USD, some in EURO, so in my store, for some products I will have to show the price in EURO and for others I will have to show it in USD. I have a store with a view and the base currency is RON, our local currency, since our customers want to be billed and paid in their currency. I made the configuration of multiple currencies, I selected the 3 currencies that I need, I configured the symbols and the rates of the currencies, but I also don't know how to show different currencies in the interface. Is there any way to select the display currency for each product when I add it? I was thinking that multiple points of view would solve this problem, but I'm not sure if this would work. I am using Magento see. If you have any suggestions, you are more than welcome. Thanks in advance!
