Personally i keep participating in campaigns but the volume is very low nowadays, i still hope good times will be back. It's difficult to tell which project will be successful since the majority of the project is struggling during their crowdfunding. On the other hand for those who joined the bounties but they always end up getting scammed, they will say that it is not worth it anymore. for now I am following the YOUengine project and I am confident enough to believe that their project will be success.
