I just think its one of those things where adoption on this forum hasn't reached the fomo level yet, so the projects are a bit sparse but it should pick up with time with more users.. when that day happens you will be an early adopter and will reap all the benefits of the higher rewards while others struggle through the ranks while you're getting more stakes from Signatures. I've done YSign campaign and they paid me faster than any other bounty I've ever done. I was really impressed with their professionalism and their updates, especially being on a growing forum where substandard work would probably pass.
