This depends on the currency you are using. If it is one already integrated into the system, then it is possible. However, if it is not integrated yet, then you cannot manage it through Jaxx. Whether or not the currencies are integrated into Jaxx, you can store in the wallet. However, the problem is when you need to transact them, then you will have to export your ETH address Private Keys then import it in a different wallet other than Jaxx. Use the following steps to do so: 1. Go to Menu 2. Choose Tools from the Menu options 3. Click on Display Private Keys 4. Check the box on I UNDERSTAND. 5. Go to Display Ethereum Keys.
