Been learning a lot about airdrops as a beginner. I've found
http://airdrop-review.com/ to be the best airdrop listing and ranking sites. The layout is very easy. It also seems that all the airdrops that they post are really quick sign ups (ie. Google forms). I've used plenty of other sites and telegram channels, but I've liked Airdrop-Review the most.
Which are you all's favorite sites/sources for airdrops?
many airdrop sites with good quality, but its better to see from the airdrop project, in bitcointalk forum this is probably one of the pretty good places to look for airdrop because they usually project them all at once
