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.
myetherwallt are the best one,, easy to use and free my friend
so, just use mew to store your erc20 tokens,,,
