I am following couple of airdrop (DST & Priv), I was following some more in the past but day by day I realised its just waste of time, so I only focus on the one that I think is potential.
DST airdrop: a community coin, although team got some problems, one thing I am sure, they want to coin to be success, so I follow this coin.
Priv airdrop: the community privacy coin, I follow this with the hope it can come across the good old Deep Onion.

I tend to stay away from the token airdrop as most of them are waste of time.
