Thanks for the info sir.. It is correct that before we join any bounty campaigns we should do our own research regarding the project.. First, we should look for the TEAM of it... If they are good enough to manage the project for it to be a successful one.. A project with no proper management probably will somehow failed.. Second, we should see the IDEA of the project.. If its unique one and its really following the roadmap it will be a good sign... You can look with their WHITEPAPER.. Then third the campaign itself.. If it is manage by a well trusted bounty manager, the bounty allocation, the social activities if a lot joining and the way how they pay... Maybe this will help for those who want to know how to choose One. and of course everything is a risk.. Still it is you who will decide if you join or not...
