if you choose to stop joining the bounty campaign it is a big loss for you, lately there are indeed many scams and also projects failing does not mean everything will fail. look at a few years ago where many ICOs were successful but there were also some that failed. it all depends on your luck when participating in a bounty campaign. continue to join the project that you think will succeed, look at several aspects such as team, manager bounty and also the concept of the project.
make it all your experience, and hope that in the future you will be lucky.
