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?
I've been out for a while in bounty campaign, but based on what I noticed, the signature campaign has a higher allocation in most of the bounty, there are also bounties that gives a huge amount of supply to the bounty campaigns, but they are mostly a failure or scam, the high allocation is just to attract bounty hunters to promote but the project has not good quality.
I suggest, you look at the most important factor, and that is quality over quantity.
Unfortunately this is very common, people are looking to find a signature campaign that has a huge bounty allocation but by doing so they are putting themselves at risk, after all it is obvious that if you see a great deal of the coins being assigned to the bounty campaign then this is done by developers to try to attract people so they promote their project, but when the time comes for them to pay those coins they are going to come up with all kind of excuses so they do not have to pay the bounty hunters what they are worth.
