Do I earn in posting even if i'm not in campaign?
No but you will earn number of activity every 2weeks but you will not earn money if you dont have signature campaign or social media campaign. Me i earn money when i work with some icos.
You can earn through posting in Bitcoin forum if you're in a signature campaign. For a newbie like me all I need to attain first to be a qualified signature bearer is to rank up. Some of my friends are in signature campaign and they do earn lot.
