The video that you saw on YouTube, was it new or old? Because bounty campaigns used to be profitable and worth the efforts, but those days are long gone, and nowadays, most of the bounty campaigns literally pay dust in the name of compensation for your efforts because they will pay you with their tokens and most of those tokens never even make it into the market and the projects die off either because of lack of marketing or a responsible team.

You can still join bounty campaigns and earn tokens but those tokens will barely be worth anything and you will just be wasting your time providing free promotion to the projects you are working for. This is the reason why a lot of bounty hunters stopped chasing bounties and started looking for alternative ways of earning money.
