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.
if you use myetherwallet and feel comfortable,, thats okay,,
but you must keep your private keys in safe place my friend, and bookmarks myetherwallet official website
but for me its better to use a hardware wallet, because i use ledger nano s to store my cryptocurrencies
