according to my opinion , it's not enough to read the whitepaper to choose a good project . We have to think about their concept , their team activities ,  social interest , etc . after that you'll realise what's the good one to join with

Best way for you to choose good bounty to avoid been scam. Always check the project team's if the are good and you need to read there whitepapers and browse about them and no what the are upto. If the can bring change to the world.

You know that the bounty campaign has a high chance to be successful if it runs by a good bounty manager. Do a background check on the project and research if the project is what the investors are looking for. I also consider the total value of token to be given in a certain bounty, $500k up to $1m is a good choice.

not all bounty managers who are experienced in the field is definitely a successful ICO project.
I personally see how the project could be useful for blockchain and where the ICO work project country should be considered as well.
and most importantly the team can attract investors and there are limitations for bounty participants so that the results me get from bounty also have good value.

In choosing a bounty you have to consider a lot of factors. Read the whitepaper first of course. Consider the team, the funding, the payout, the community if how active, the advisors and of course the feasibility of the project and how it going to serve the community.

There is not a simple recipe for success. But the most important is that the project has to be legit. Check the coin, the team, the product and the whitepaper. And the first moment that something dump it right away and search foe new one.

For me, In choosing bounty, you must know the background of the project, must read the white paper if the bounty is good.

To determine the return on investment in an ICO, there are many factors to analyze. We need to analyze the business processes of that project, partner with the project and Dev's reputation. I think these are important factors for evaluating an ICO and determining profitability. Good projects will usually be listed on Bittrex or Binance or Bitthump. Then, the price of ICO will be multiplied by 10 times when put on the market.

I will explain to you about this. the criteria for choosing a bounty is an important component, since the right choice of start-up depends on the level of your reward and the amount of time spent. for example, you should pay attention to the project as a whole: for a detailed explanation, white paper, the adequacy of support managers and the amount allocated for the bounty. it will also be important to mention the development team: it should be a professional and competent team that does not hide their faces and previous jobs. Further, pay attention to the amount of financing and support of large investors. these recommendations will help you reduce risks and choose the most suitable start-up for you.

Learn, all information about bounty already exists in this forum. You should first find out the bounty ratings through sites that provide info about it, then find out in this forum, read and understand internal factors (team, adviser, white papper etc) if you believe it is good, then continue.
