Hey there,
Wondering which criterias do you follow to pick a bounty where to participate?
Definitely should check the team, roadmap, whitepaper, but is there something specific that you consider before participating?
Hmm, for me, Firstly, i always check social media of the project, like "the date of create homepage", "the page show the team when working or not". It will give trust for me to support the project
Secondly, check ANN Thread, learn more and read the discuss about the project, summarizes all comments or feedback.
Thirdly, check more information the member of team, you can find it on the website and usually the website will provide you direct link into their social media, like Linkedin, FB, Twitter, telegram. etc. It will give you a picture, the team is real or fake
In some case i try to send direct message to member of the team and ask some question hehe
