First of all, to even receive any tokens, you'll have to join airdrops.
Whetever if it is a google doc, telegram bot, or website anyone of these are
worth joining, as you get tokens for free and they can potentially become a lot worth.
#1. Make sure you have joined an airdrop.
#2. Go to myetherwallet and copy your ethereum adresse.
#3. Go to https://ethplorer.io/address/ [YOUR_Adresse]
#4. Put your adresse in the search field, and it will check your balances.
It looks like this, if you have any tokens available.
I like this. Followed you
