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?
No, I do not think So.
I have not earned that much from bounties yet but I think in long run I can, I have joined some campaigns but some of them turned to be a scam project or there token just worth nothing. So, It always depends on luck if the project gets fame and get investors a lot of and the project is real otherwise you will earn nothing.
