You can earn fw amount of bitcoins here in this forum by just joining signature campaigns who accepts newbie as their participant but htey only give low payment rates. If you have skills to offer then go to services section you might find a good one which suits your capabilities, maybe you can make good decent amount of money on that job.
A newbie wont earn a decent amount with signature campaigns as even if a campaign accepts newbie they wont pay him much for that as it depends on post qualities and newbies mostly are not able to do constructive posts as higher rank users can.
