Its not hard to choose a bounty. All you must need to do is to check its background and if it suits you or you want to be a part of that bounty campaign then you may join. For you to need it, you must need to read in advance in any bounty campaign for you to choose that right one that helps you to gain money. I just give you an advice to read and read for you to understand it all.

experience is the way to choose for a bounty project. you must have plenty of experience and knowledge so you can make your choice.
 nothing is easy in crypto, everything must be based on research and analysis. just as you would like to try to invest. so, i just suggest. your most important point should be to find a lot of knowledge and experience about various campaigns.

if I am the first one I will probably see his bounty manager, then his company, and of course with his team, and I will check their website on scamadviserdotcom, to see how convincing they are, and I also see how much bounty hunter enthusiasts

sorry for my bad language

Base on my experience most of the bounty campaign in the bounty section  is not legit. Which is there's no distribution of token after the ico.  So if you don't want to waste your efforts on it must choose bounty which manage by trusted user And also high ranked users..cause bounties in the bounty section is so difficult to determine due to some scam ico project nowadays on bounty section. 

Myself I like to participate into bounties runned by Syllon. This guys can be trusted and the projects his picking are legit and they have a real chance to succed into ICO's and after ICO's. There are others things that I do before I pick a bounty like checking the team , project , roadmap and so on.

Pay attention to the team, look for where the team has been involved before and how these projects are developing. If the team is experienced, then you can believe

Choosing a good bounty campaign you have to go through very carefully about the white paper and developer team. i think their mission and vision would be the best way for finding out for choosing a good bounty campaign. For me, I always try to scrutinize of the budget allocation regarding the bounty campaign, also recruited bounty manager would play an important role for this issue not only that but also checking the team is a vital point.
And finally their road map is the most crucial part of this issue. So you may follow what I mentioned in this post for choosing a good bounty campaign.

Even I wanted to join in few participant, mostly those potential ICO are those many users joined, that's why there were times I looked into manager rules, it will be much better if they are strict and eliminate some that are not following rules. But always look into the project potential done manager and get involved in promotion properly.

You shouldn't belong on this forum because you are only want to earn some monet throughout bounties. You will be only (or mostly) spamming on this forum to earn some money.

I always check the team because they are the one who will make the project goes. We only need to look and read the whitepaper to find some additional information not inlcuded in the announcement thread and website. We should not forget that the whitepaper contains all information about a project, then you should not miss to read it specially if you also want to become their investor. But if you are tired to read a lot of stuffs like that, you can base also a good bounty according to number of higher rank members like, hero, legendary, because they knew a lot than most of us and sometimes they are the most diligent when it comes on reading. That's sometimes I do, when I'm so much tired.
