I'd like to suggest you the coinomi wallet, they are an android wallet tho (hopefully you have android phone) : they are multi-coin wallet that let you in charge of your private keys, your private keys never leave your mobile device. You backup your coins simply by writing down your wallet seed/paraphrase that you have been given 1st time when you open the wallet. From this seed the wallet generates private keys and addresses. They are also HD wallet if you like a bit of privacy.
Other solution would be jaxx.io wallet (they are multi-coin , multi-platform) they have lower amount of alts that you could keep but they are also a popular wallet.
It all comes down to which currency you really want to keep, if you want a wallet for desktop only you should check exodus.io
These wallets came to my mind first , if you are looking for multi-currency one, most of my time I use coinomi and jaxx, but it all depends on your tastes.
