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 agree with this, I think this year has a lot of scams, because of the hype of many people about bitcoin, ICO and airdrops, scammers take this opportunity to take advance. Last year, I received some legit airdrops, I just regret of not selling it when their price goes high last year. So I have nothing to do, but to hold those coins and just wait again if it will give me a nice profit of holding it for a long time. This year I gained nothing from airdrops only small amounts of token with just cents in value.
same thing did happen to me . these past months i do recieve nothing from joining a lot of different airdrops but compared to last year i do somehow recieve something on my wallet even if their value is not really good but atleast i feel replinish because my efforts were not wasted for nothing . right now im still holding most of my tokens because the market is still sleeping . i did regret because i was too greedy to not sell them due to the reason that i am not yet contented from thier price . i wont make the same mistake again ever .
