Generally, it is not possible to send altcoin without a fee. Because the altcoin system works based on Block Chain Technology. Some mining fees are required to send altcoin. So there is a fee to be sent to send the altcoin to the wallet address.
But altcoin can be sent without fees but it is not in wallet address. Altcoin can be sent through personal email without the fees. It's actually done to send the altcoin internally. In that case, the sender and the recipient need to have the same wallet. If not the same wallet, then altcoin cannot be sent. This is the only way to send altcoin without the fee. If you have any other idea kindly share with us. Thank you
There is no way you can send any coin or any crypto without any fee.
You can take a practical life example, like if you send any goods whether it's physical or virtual you need to apply some fees.
Yeah in case of Bitcoins you can use segwit wallet that will surely help you to reduce the fees and this will ultimately lead you to save some bitcoins for you.
Hope my suggestions help you out.
