I think being a bounty hunter,you will really encounter that kind of trials but I dont think that it would be an enough reason for you to quit because there are alot of bounty out there and all you need to do is to find a good bounty.You must have to double check the project and also you need to be more careful.If there are bointies that are not paying well there are many more bounties the are paying as well so all you need to do is to search for those good bounties and never quit.
Its just being a normal that there is bounty that we encounter sometimes we chosen not good. But there are more chance that you can get a good bounty, that you should be choose wisely, and you should take a risk also if you are a bounty hunter. Just continue to join and someday you will find the best project.
In all honesty it is really difficult now to find good bounties. 2017 was the best year for these bounties. I even got good pay during this year. But I guess because of the many scams and malicious campaigns that tend to victimize new crypto enthusiasts and also investors, the public became weary and most good campaigns either had low turnouts or don't do bounties at all so that they can also make themselves secure. Anyway I am still hopeful that good times will come.
