Please check out my thread here:
https://bitcointalk.org/index.php?topic=3232745I am curating a list of 'highly promising' airdrops.
I hope I can help you find 'high quality' airdrops. By 'high quality', I mean:
airdrops that are highly likely to result in tokens received in your wallet, and
tokens already of value (listed at exchanges, ICO sold out, ICO cancelled in lieu of private placements, etc), or will be soon (advanced stage of funding rounds), and/or
early stage projects with existing users, solid MVPs, working demo, established partnerships, founders' history, etc.
