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 really. If you are more careful then no one will be able to scam you. Looking for high quality airdrop projects, projects that attract many large investors....
For me, airdrop is something very interesting ... and I like it.
