Ledger Nano S
Trezor
You all really need to buy one of those wallets, probably this is the most easiest way to protect your coins, it is not only on the safety, they are accepting segwit too.
Anyway, i tried the Ledger Nano a few months ago, it works fine, and the fees are reliable.
A few days ago i opened it, and the fees were aproximately 3/4 of the actual fees from the network, if they were 30, you needed to pay 20 bucks.
The trezor is almost the same, only that the interface and the design are a little bit outdated.
