The title of this thread is bit provocative, but the fact is that most people have a bad experience with airdrops. According to several airdrop hunters I spoke to, the majority ICOs don't pay out at all.
What's your experience with airdrops? Did you get scammed most of the times?
Not all airdrop is scam sometimes we make money through airdrop but mostly airdrop are scam so, be wise to choose airdrop, and search for good strategy to join airdrop campaign.
I' m not scammed by any airdrop but I say not all airdrop is sacam because I have friend who earn more money through airdrop.
