You know that that's even less than the hourly salary for most decent jobs? I don't see it being fair from any angle.
The campaigns might lurk the bounty hunters by showing there are thousands of dollars worth of bounty pool, because of which a large amount of people participate. The campaign runners don't have any problem, because the more the merrier for them. But it affects the participants directly because the funds are allocated to each user according to the stakes, which total up to a very less amount as previously imagined.

Also, as soon as the payment is made, these hundreds of participants quickly rush to cash out their token/coin earnings collapsing the market, bringing down the value of their own hard work.
