Which wallet do you use for storing your ERC-20 token?
I personally like MEW because it's very easy to use. Some people like Trezor or Ledger but personally I have no problems by using MEW

In MEW you have complete access to your private keys.
The most common and good wallet for this type of coins is MEW. I think it is all advised because of its ease of use and good security. I like its minimalist design in white. It's best wallet which I know.
