There are a lot of accessible wallets for ERC-20 tokens out there. You can use Metamask, MyEtherWallet, Hardware wallets, or mobile wallets. Just choose what you think is more convenient for you to use. The most secured way of storing your crypto is keeping it in a hardware wallet.
The choice of the wallet depends of for what you need the cryptocurrency. To simply store the savings it is better to use hardware wallets. Trezor can be as an example. For everyday use it is better to find a desktop or online wallet.
