I think the problems most bounty hunters are facing is entirely their faults ,bounty hunters are responsible for their end results because many never learn to read or do thorough research and later they will start complaining about time wasted of bounties.
I really agree as you say ... there are lots of bounty hunters who complain about the results of the campaign they did 2 - 3 months. because before they took part in a particular project, in my opinion that they did not carry out detailed research ... such as the TEAM they have and the Whitepaper and roadmap that is certain ... and what is important for me is the bounty manager who has managed many projects ..
