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?
No it's not 99% but 100% are scams,. i never got any payment from any bounties i joined and participated, so it will only waste your time, you should just join bounty campaign if you want to earn money
