No, this is only 2018 current condition. If I compare with last year (2017) there are many legit airdrops. Like BLUE, ELTCOIN, EREAL, BITWHITE, REBL, and many more. So, I can say 2018 is the worst time for airdrop. I think the last Airdrop which gives good token was POLYMATH.
I totally agreed with you because right now there are just very few legit airdrop, almost all the airdrop out now are scam, they dont pay after the ico is over
