You probably do not understand why people are participating in bounty campaigns. At first, they still believe that hype will come back and every altcoin will moon. Secondly, they are used for this job and do not want to learn new ones. I do bounty campaigns because I meet both criteria

I agree with you because most of us are willing to focus some bounties that have some chance to the moon if these project has always a good movement. And if not well we ignore it and find some another bounties that suit our taste, Actually as of now we encountered trusted bounties but few of them are we seen maybe in coming months has more of them come up.
