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.
Totally agree with you. Although this year's airdrops are mostly unreliable (mostly asks for donation so basically an irony to being free), last year's airdrops really went to markets, EBTC is one of the airdrops to and I know a lot of my friends were fortunate to receive that time.
