MEW (My Eteher Wallet) is one of the first choice if you would like to interact with ERC tokens, there is also posibillity to store NFT tokens. It is especially useful to see the balance of your holdings, to send and recive tokens. Due to its features MEW was handy in the ICO boom. For the begginer MEW could be little bit confusing (you have to set the right contract and decimals if you want to add the tokens). One of the key element (and advantage) is that you own your own private keys (it is non ustodial wallet).
