I don't think that there are any newbie campaign that can give Bitcoin for your posting , so here I would like to suggest you to first of all get better study and better discussion about the Bitcoin and altcoins in this forum and wait until your rank get up at least to jr. Member , because most of the campaign starts from the jr. Member or above .
So here I means to say that in the starting you need to hard to get knowledge and rank level , so that you can eligible to join any campaign .
But still here some social media campaign are available where you can make earnings by sharing the link of the services and get paid in Bitcoin .
Last month that I seen the campaign was let's think why future  , May be they can accept you , just try to see at the thread .
And also in the present time you can a campaign if you can get jr. Member  https://bitcointalk.org/index.php?topic=2041816.msg20322607#msg20322607
But you will only get digibyte coin for the joining campaign .
