that's why you have to do an analysis of each project that you will promote, make sense or indeed fulfill the objectives for the project being developed.
if not you can choose another project to promote even if the project offers a large prize.

Yes, of course, It's like you spend your time to invest in a project despite your money. So our time is limited, that why currently we need a deep analysis before participating in a bounty campaign. There are still quality projects out of here, but they'll not allocate a large fund for hunters, it's my experience after a year in doing bounties.
