I have heard abouty bounty campaigns and i searched and found that you have to be a member of bitcointalk and have a good rank...but i am just a newbie..are there any good bounty campaigns which are accepting newbies in their campaign
Try to get some good quality post. Someone should at least give you 1 merit to make it as a Jr. Member.
Once a Jr. Member, you can join bounties depending on the bounty program.
