Are there any campaigns for newbie to get Bitcoin ?
It is very rare to find such and if you eventually find one, the reward will be so small. So it is better to work towards having a higher rank, which will also increase the stake you would earn.
I can also see that you already have merit, which is one of the criteria needeydto rank up to the next level.
Just keep making relevant and constructive posts, which will enable to to have approved posts as activities.
