Actually Airdrop is waste of time. May be you will get 5/10$ from Airdrop. But you need to wait long time to listed on exchange. Before get token there is too much formality, even some of ICO asking for KYC. I think it is too risky to submit KYC. After you got token need gas fee to transfer on exchange. Then you need exchange fee. So you will not much benifite from Airdrop.
