You have a choice of several that are safe. Here are a few of which you have to choose from. Trezor and Nano Ledger S are hardware wallets and are worth a certain amount. The Trezor is priced at 99 $ and Nano Ledger S 65 $. Then there are free wallets like Electrum, Coinbase, Jaxx and MyEtherWallet. For me there is a Trezor and I use MyEtherWallet.
