Deceiving rate of bounty campaign is a pain in the arse for hunters however experienced hunters can realize that. Somehow the rate is not very important as good projects can result in 5x or 8x profit. Number of tokens is more essential then.
I think this is not a new form of scam since many projects before are over valued and they promised to be a good coin, bounty hunters must already know the difference of a real coin and its real value, dont waste your time for that kind of bounty campaign. There must be a valid reason for that bounty rate, and its better to ask the management or even tha BM, they can answer you for sure.
