Airdrops are everywhere now: you go to telegram and channels send you tons of airdrops, you go to youtube and they give you videos on how to participate in another airdrop, you try to lose your self hanging with friends and one of them starts telling you about airdrop he participates in.

I noticed that only scam ICOs offer airdrops to spread thei shitcoins. But good reliable ICOs such as eCoinomic.net have no airdrop, only bounty. So do you guys agree that nowadays airdrop is an attribute of scam?
