I'm fairly new with this forum but I heard about earning bitcoins by using your signature spot to advertise. How do you go about doing that?
you can earn bitcoin by put their advertisement in your signature space
that advertisement will show every time you post in this forum
before that you must join signature campaign, most of all need member level as minimum requirements. but you can find signature campaign who accept newbie, just click link at shorena's post above
there's two popular types of signature campaign :
pay per post - you earn bitcoin based how many constructive posts that you made in periode of time (usually weekly, monthly)
pay per fixed amount - you earn bitcoin based on their offer in period of time, with minimal posts must reach. (for example : 0.05 BTC / month, minimum 50 posts made)
