My first instinct is to say 'No chance'. Airdrops in general will get you a few dollars at the token sale price, and likely even less once they hit the markets. No harm in taking part in some here and there, but most seem to be mass advertising promotions now, with little value for anyone taking part. Of course there will occasionally be a winner, but as a full time occupation, nope. Keep going with that full time job and build up your portfolio of freebies on the side.
