I think you are not going to get any bounty campaign if you are Jr.member.
There are still campaign' that are considering jr. members to allow in their campaign / bounties.
But some of the campaigns hired Jr.members also so you can check the bounties section for further detail.If a campaign is running by a reputed manager then it can be considered as best campaign.
Your campaign is accepting Jr. members and it is with bonus if they had some merits. Just avoid those campaigns that doesn't have fund of paying, better if there's an escrow and its also an assurance if the bounty has an experienced manager.
This is the best place to find your best
bounties.
