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.
I am poorly versed in wallets, which is why I use the one that was advised by managers on this site. MEW is a pretty good wallet that meets my requirements and is recommended by verified users on this site.
