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 seconded into this one which the thing you are saying on here is true where airdrops back in previous years are almost legit ones and do paying but now when the trend when it comes to airdrops and becomes popular it gradually becomes more worst because most of them arent paying or just giving out total shitcoins which dont really have any value at all thats why i dont already engage into airdrops into this year unlike before that joining them is somehow give a chance on making some free money from free coins.
