I am looking to try out a bounty campaign using signature but I don't see anyone worth my time right now,
I suggest you about United crowd bounty. UCT token already listed on exchange. 80% budget of this bounty is for signature. A Legendary member has earned $4.5K from its first round signature campaign. I earned $400 by promoting two weeks in the first round signature campaign as a Full member. Currently running the 2nd round of this bounty. You can participate in this bounty.
