This is an issue that should be attended to . Bounty managers should always have it that they need to assist hunters to get what their reward is. Some developers have taken from hunters what their benefits are.
There are some points that should be tackled about this...
1. Ensure that rewards are distributed before they go into exchange. This is because when the coin goes into exchange and starts performing and increase, developers find it difficult to redeem the promise. Dego bounty is an example on that.
2. Always have a good bargain protection for hunters so that no matter what, the reward will go to the hunter after the bounty.
3. Suggest payment in valuable altccoins because protection of workers should be important to any company.
Two things every bounty hunters should look at on a campaign, who manages the campaign, and if there is an escrow, a good manager always see to it that workers get paid in time and in full, his credibility and feedbacks coming from bounty hunters are the ones that will build his reputation, escrow is a guaranty that the bounty hunters can work without thinking that they will not get paid and they are motivated to promote the project.
