I prefer a bounty with limited participants so that everyone can get a higher reward than usual. It would be better if they rewarding the hunters in the alloted tokens weekly than receiving a stakes. Well, weekly stakes is not that bad actually specially if there are less participants in signature campaign.
I like your comments, but an ideal prize campaign should have great potential - wise benefits. a good campaign is also a betting system is still the best choice. because it actually divides the profits in the amount corresponding to the prize participants. so your hard work will also pay off and so you will get a reward that suits your hard work.
