Many people misunderstood that bounty is not an investment. I think that concept is wrong. In bounty you don't invest money to grow or to earn money more but Bounty is  an investment of time and effort just like working in normal offices, you just need to work hard and then it pays off. Bounty is about offering your service to the ICO's and campaigns that are available just like looking for a job. It's all just the same in the real world. If you join high quality campaigns, you can have  good profit.
