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?
Its really are can make a lot of money on participating on airdrop ang bounty campaigns. I may say that its a lot easier before than today, because the Etherium before has its highest value and has it popularity at peak and also the token value before are much expensive than today. Having a lot of earnings on airdrop and bounty depends on the result of such campaign I may say that your earning on these airdrops and bounty campaigns are just a matter of luck.
