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?
The majority of bounty campaigns allocate moe on the signature campaign and even if there are less allocation you still get more because of fewer participation compared to other campaigns, and if you have a good rank you'll get more, I remember joining on the last week of the campaign and I still get a higher stake than lower rank participants.
