it is now august 2018, airdrop isn't as good as it used to be.
airdrop nowadays more like a hit and miss.

back in 2017, a there were a lot of good airdrops, like rebl, btw, leverj (this one distributed in mid 2018 though), and all gave me good amount of $$$.
the highest one was btw (now bitwhite).
i got around 1000 coins iirc, touched $0.9 when it entered exchange.
all from just filling simple data through telegram bot, no kyc needed.

those were the days
