Airdrop never profitable at this time even i see bountydetective service using many airdrop but i don't participate yet. For a airdrop rewards 5$ to 10$ need kyc pass how the jokes? Otherwise airdrop easy work with got money but since it was impressfull 2017 year even not now. I won't agree passing kyc for 5$-10$ lol so airdrop totally time waste at now.
Instead of doing airdrop you can actually do a bounty campaign in this way you can earn not only 5$, 10$ and so on..but more if you think most of the airdrop today aren't profitable anymore.. i can help you to choose a safe campaigns go to this
