I'm still a newbie to cryptocurrency industry. I recently joined in a few airdrop events. But, still I have 0 tokens available in my MEW wallet. Should I have some Ether on my MEW wallet in order to receive tokens?
no, you do not have to have some tokens in your wallet to receive tokens from airdrop. it's just a matter of the airdrop organizer itself you can see and check the status in the airdrop spreadsheet whether or not you get it. if you are received but have not received payment you can pm to the parties concerned to confirm your payment.
