More and more airdrop is a lie, I do not recommend participation in airdrop, because there are at most a few 100 airdrop quality, so I think it should not be a waste of time.
Almost all airdrop are trash, you can simply go to the first page on their Announcement thread, there are so simple and only talk about airdrops. All these thing are trash and when the coins accepted on etherdelta, the dev will dump all the coins. Only 1-2 project airdrops will become succes others are not.
