There's many site list new and hot or exclusive airdrops daily. You can find it online via google or here also. Before, I follow airdropalert.com for the airdrop but since I found that the token I received from airdrop is not match with minium trade amount on IDEX or some other market so I decided not to join to airdrop anymore. Instead of airdrop, I join bounty campaign so I could earn more than with the airdrop.
