I only join airdrop after some research and prove that's a legit project. It's only take 5 - 10 minutes a day for a project. Havven, VIO and TrakInvest airdrop has been payout and I get quite amount of token value from it, it's worth it!
Btw, you guys can check out new and legit airdrop at: https://alertairdrop.com/. Update everyday, you can choose to join only Featured airdrop and saving your time.
