Bounty hunters do not provide value
They do not get the message out to communities that actually purchase the token - and once they receive the tokens they sell it straight away
LOL... Seriously?
If you think like this, then I am sorry to say that you don't know anything about the bounty campaigns or the hunters. I have been in to this domain for almost three and a half years and I have seen many little-known projects gaining publicity and funding as a result of hard work and effort put in by the bounty hunters. But then it is always to blame the hunters, as they are like an easy scapegoat.
