The average bounty allocates the most tokens for Twitter, Facebook, Signature, Youtube and Article campaigns.
is there a bounty that allocates higher tokens to the Signature campaign?
A lot of bounties has higher allocation in signature campaign such as Xircus (you are now promoting it), Foobee, DopeDoge, Crypto Stakes. But you are allowed to take only one signature. I think you already know how to find a good bounty.
