Bounties are profitable, the problem is that nowadays it is very easy for anyone to create their own tokens and call it a PROJECT !!! I mean there are many new tokens that do not have even a positive project but they will launch a bounty just to get attention and in the end, they will disappear. That is why only 10% out of 100% new projects will succeed, today is just copying and pasting from other projects, only a few are real.
