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.
A successful hunter never be quiter there's always a good campaign in the forum as advised by senior members we should double check the team behind the campaign and see to it that the manager of that campaign has a good track record of his name.
