Actually, at the moment, there isn’t still a hardware wallet that supports ETN.
If the paper wallet is too much of a burden for you, you should trust the online wallet, which is way better than storing your ETNs at an exchange.
Maybe in the future, other GUI wallets will accept ETN as well.
The wallet I trust the most is Exodus, and they accept new coins at every update, which takes place every 2 weeks or so.
