In my opinion, Bitcoin Signature Campaign is more worth it rather than wasting your time in Airdrops. It seems that airdrops now rarely give payments to those who join compared to last year. I have over 80 airdroped coin in my wallet in which I cannot even make use of, am already sick and tired of taking airdrop every night and day which turns out the becoming a shitcoin.
I totally agree with you but to join the signature campaign must understand english, in 2017 I found lots of quality airdrop but this year a lot of scam and shitcoin. for the moment do not expect too much money from the airdrops. I've been lazy and tired to join the airdrop.
