i am guessing the campaign is open to just few people since the calculation will not accommodate much with respect to the amount of tokens allocated to the bounty.
Our total funding cap is a lot lower than many of the ICO's out there, so you are correct that the bounty is proportionate to that. The total cap for our project is 20,000,000 tokens (20,000 ETH). The total value of the bounty program is 2.5% of the raise, so it's capped at 500,000 CBI (500 ETH). There is still plenty of opportunity to earn significant rewards by participating in the program.
Let me know if you have any questions about the project.
