All we have to do is do the analysis as well as possible, search for information about the project and try to read the whitepaper described by the dev project. Usually a good project will produce a good bounty too. I will usually see the ranks of teams in the developers, when they have a good reputation and history so I do not hesitate to invest in the project, otherwise I also will not regret to follow the bounty they held. Oh yes if we are hesitant then we can follow the bounty campaign is managed by a qualified manager, usually a quality campaign manager always offers an interesting bounty and proven to pay. So choose the best and we should be able to choose what we will do, without action then we will not get anything, believe in our own ability and ability in doing analysis on various projects. Experience, knowledge and skills will greatly influence what we will get.
