You do a little research before joining a bounty, but not sure if bounty is profitable or not, as myself i haven't participate in any bounty yet.

Before joining bounty you must first read and research about the project.If you think that the project is good and you feel that it is trusted you can choose it.

There are many different factors, but none of them guarantees. Try to choose by bounty manager. Recently there was such a topic.

I agree. You need to learn the command, read the documentation. Just pay attention to the manager who leads this campaign. In addition, you need to choose a campaign where a high percentage is allocated to the bounty.

I start by checking the overall appeal of their ANN and bounty thread here on the forum (also, how popular the thread is in terms of how many people read it and how much that number is increasing). I follow up by checking out their website and if it looks good to me, I start reading the whitepaper for the first (quick) time and get some sense of what the project is all about. Then I check their social media pages (twitter, Facebook, reddit, etc.), how many times they are posting per day and if they have some quality content (quality over quantity for me, one post a day is enough if it has some meaning). I also look at the numbers of followers, likes, members. There needs to be an "organic" community if you know what I mean. People need to be involved in the project, not that they landed on the project by referrals or even worse by accident.

Somewhere in between I also check out the team and their past references (where they worked, on what and with whom), meaning if they hold some strong positions in the "cryptoworld". Also, having big names for advisors can only be good for the project. Then, checking out reviews by ICO review sites and blogs comes into place. Ratings, articles or everything related to the project is important. I also check if they are featured on some spreadsheets by well-known YouTube ICO reviewers or if someone has them mentioned in their YouTube video that gathered a lot of views.

If everything above satisfies me, then I read the whitepaper more thoroughly the second time. I usually then start bounty hunting for that project and hope it will succeed.

I probably forgot to mention something as there are a lot of factors involved, but these are the important ones for me at the moment. Hope this helps!

broad insight and to detailed telitian to a project is obviously in need of it, what if we want to invest in the project do not we lose in the future because of our insight that the project will be less

To choose bounty, I'm usually see whitepaper, the team, also checks the icobench checking the project,

everything can be seen from the experience we have when using a trusted gift. they are the first time we use them to see how they reward them. whether it's really looking for karuniA or just a scam

Check the credibility of the bounty campaign first . Do some research to make sure its legitimacy by looking for any feedbacks regarding the campaign because some of the campaigns have good offers but in the end it is fraud or scams and for you to earn more in a bounty campaign choose a campaign that has few participants because the less participants in a campaign the higher profits you may earn.
