I have been doing airdrop & bounty for almost half a year but still have not earned $ 500. I usually do 10 bounty + 15 airdrops per day. I won 20/24 hours to find and do Airdrop & Bounty. Some days I do not even sleep to do them. But the result I did not make much money. Did you make money with Airdrop & Bounty?
Sorry to hear this but I think this is due to the kind of bounty and airdrop that you participate in, they may not be good projects and moreover, in bounty and airdrops, rewards are distributed to participants according to their rank and allocations given. Take your time to do a very good research of the available bounties and pick the one to participate in based on the research you did.
