Unfortunately almost all campaigns are for Jr. Members only.
No! As far as I know, Jr. Member is the minimum requirements to join in signature and translator campaign, but not in social media campaign (facebook, twitter, medium, and telegram campaign), and media campaign (youtube, article/blog etc.). So, you can join in these campaign "social media and media" as a newbie.
Please pay attention to it as well:
But before earn you should learn. Otherwise your time will be waste. Every one giving you way to join bounty. No one giving you advise. Maximize your knowledge about crypto & forum.
I think newbies should also get a fair chance here for their time as they're the ones who need to wait a sufficient time before making another post (which makes them know that they shouldn't spam with BS and learn to wait). Newbies should be given a chance, if even with least amounts, so as to let them experience how much efficient they are and what efforts it takes to earn bitcoins.
A great initiative by Btcforjoe for the newbies and above ranks to get monetary gains as well as merits by presenting their knowledge to the forum.
