Is there any Restrictions to join bounty if i am Newbie?
Most bounty campaigns accept newbie accounts for social campaigns and articles but there are few that requires you to have at least a specific rank before they accept you.
Is the bounty program for only bitcointalk users, i see i should add and use my user name of bitcointalk.
The most popular platform that project managers use for bounties is bitcointalk which requires your bitcointalk username when participating but there are also other platforms like bountysuite, bounty0x and some others which have their own specific rules
