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
This might not really work, if it is to be this way, it means if I am to invest in 1000 different coins, it means I have to be on the wallet of each of the projects I am investing in which will be quite tedious and difficult to monitor your coins or tokens, cant imaging me opening lots of wallet every time I want to view the progress of my tokens or send/receive tokens just because I am avoid a little charge using a general wallet. Well for the one you said about email, I have not really heard of this and I think it will be nice if it this is possible.
