I only participated in a few bounty projects and if I participated in all the bounty projects it would take up some time,
if your not busy and if you have alot of time to burned , why not join as much as you can . its not bad at all to join a few knowing that not all are going to pay well .
but the results were zero, so I was less enthusiastic about participating in the bounty now,
did you follow the bounty that you join ? its impossible that they wont post the result . they will say that they fail or not , so its not zero at all unless if they dissapear without giving proper announcement .
almost all the projects I participated in were unsatisfactory, it was very difficult now to find projects that were truly produce, do I have to participate in all bounty projects? Suppose I only participate in social media, so that many projects can be followed
you are not alone with that problem . even me i also experienced that and what i do is i take a rest for a while . stop burning your energy if your not motivated . instead spend your energy on things that you think worth it
