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.
bounty hunter just takes 2-3% from a total of supply. i don't think that really gives the effect for the market. even not all bounty hunters sell their token instantly. as i know, also many bounty hunters which hold their token after bounty distribution.
