Don't waste time on airdrops, less than 1% of airdrops give you money. You will face a lot of risk when doing the airdrops, my Exchange account was attacked when I was not careful using the same mail to join some airdrop.
Good advice. I can only add that if you still decide to take part in airdrops, which I personally do not advise you to do, then get yourself a separate wallet, email with non-duplicate passwords.
