As bounty hunters its your job to find a good campaign don't just rely on others suggestions you should always have your own way to determine if the project you want to be part is legitimate.
As for my suggestions I create a thread that only list a bounty coins or tokens that only listed in exchange.
Here is the link
https://bitcointalk.org/index.php?topic=5232710.msg54025514#msg54025514Just because a project is listed on exchange don't give them a check as a legit campaign, take a look at digitalbits, they are listed on exchange and doing absolutely great still refuse to be pay hunters reward,
To me that is not an authentic criteria to determine which campaign will be rewarding, there are so many disappointment from project owners that left hunters wondering and confused.
I know that's why I said first that do not rely in other suggestions always and you need to make your own research.
He is looking for suggestions so I help him by giving my created thread list in exchangeable bounty campaign . I also that not all of the list I provided is one of the best but there is also campaign in my list that paid weekly.
