As of today, there are still potential income in airdrops and bounties but not the same way back 2017-2018 where in a lot of great bounties scattered here in forum. Bounties that can give you a great amount of income like 4 digits and even 5 digits in usd.
some will not give us anything. You can view some of the recently launched projects and create campaigns. It wasn't until the end of the campaign that the bounty manager stopped the campaign because the team did not respond to the bounty manager. also, no news until the campaign is finished for distribution. It all depends on how we can choose the project.
I recently experienced it in student coin bounty campaign. Wherein the project team did not follow the final spreadsheet came from the bounty manager. Student coin team said that the bounty campaign did not add any contributions to the progress of the project that is why they did not pay almost 90% of the bounty pool.
