I have not known for sure the good bounty program and quality until the end of ico finished with the number of investors that many and reach hardcap. but we can just follow all the bounty is still new and many who follow it.
Sometime the campaign get the good response depended upon the manager of the bounty. If some bigger manager does support some campaign or run it is a chance that the project is genuine and has a good scope in future and will not turn out to be a scam.
