Bounty campaign is the easiest way to earn money in crypto currency if you are not investing your cash in crypto then it's either you are participating in airdrops or bounty campaigns but bounty campaign gives more task than airdrops, so it pays more than airdrops though it requires more time and dedication but at the end it really worth it.
Yes, of course the bounty gives more profit than airdrop. For now the airdrop is no longer interesting because too many are scams, even though they pay but the amount is too small and becomes useless.
