Even though it's an old post, it says all the things that are needed for a newcomer to join and learn about bounty campaigns.
But campaigns aren't as compelling right now as they used to be when fewer quality projects, or quality projects, only provide a fair amount of money to build campaigns.
The campaign now for new projects is like a box of chocolate, you never know what you are going to, some projects you are working has good feedback but it ends up a huge failure, and some projects you ignored turn out to be successful, so it's very important to follow all the projects you are working in, so you'll know if it's worth staying.
From my point of view there are some ways we can protect ourselves from scam projects. We definitely should investigate the meaning and idea of a project. So it is important to view the web-page and find out what services this company is going to offer, and what the mission is. Also we should find more information about team members of the project.
We should find out if they have successful experience in launches of different projects.
