Bounty hunters are alwasy blame for selling their tokens so quickly without waiting for the project develpment as outline in the roadmap. I don't think bounty hunters are to blame because a lot of bounty hunters hold their coins for years.
Sometimes, bounty hunters are also investors. I also invested in Current project and also promoted their projects. I am a young investor, I only have $ 200 to invest and I want to receive more tokens and force me to participate in the bounty program.
In fact, a good project will know how to regulate the price and not make the price of the token reduced when the bounty is distributed. Like CPT and OATH are doing, they really have great strategies.
