Is there any airdrop before this year ends?
Good way to giveaway some coins to make the everyone happy! lol
You can join in the bounty detective airdrop telegram group and I do believe you can get the latest airdrop from there.
You can also participated in the DIA or XRP airdrop but these airdrops require you to have some amounts of DIA or XRP. I guess the only difficult thing for you to know is that airdrop legit or not.
There are some threads on the altcoin service discussion which has been giving the latest information about airdrop.
