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
Safe bounty campaigns by cryptoaddictchiehow do you know that ? what if bounty is a scam , you wont earn even 5 usd . 5 usd is high now but expected airdrops pay right now is only 1 to 2 usd , with that said amount its not worth it to do kyc but its a good way to earn some few bucks without investments needed . thanks btw for the link that you shared . that might help users here but i wont only agree on its title . calling them safe is still questionable know that we have a good number of scams
