I stopped joining airdrop as my experience showed me that in most cases it is just waste of my time. I prefer spend my time in a more efficient way.
I agree. When I started here, I joined lots of airdrop as it seems like it is to earn through this. But after spending lots of time, I didn't get any in return or it is not enough. These days, I only join airdrop that seems legit and won't waste my time.
