Honestly as a beginner, I'm eager to participate in bounty campaigns and explore various free earning opportunities.
Bounty campaigns is not worthy to join anymore because most of them is scam. Signature campaign and Job offer on the services section is the only way now to earn profit here.
As a starter, @OP can join bounty campaigns since his rank is not qualified to join signature campaigns. It is a good first hand experience, IMO. While learning the left and right of cryptocurrency, he can start his journey to earn on bounty campaigns, there are bounty campaigns that pay but the worth of payment is unknown since it can be worthless or huge amount depending on the success of the project. Although some of these bounty campaigns failed to pay their participants, the risk can minimize by joining reputable campaign manager that also manage signature campaign.
If you want to start earning, Try to familiarize the forum by reading the rules
https://bitcointalk.org/index.php?topic=703657.0. Then contribute in the forum to rank up your account by engaging to other user by constructive post. All the earning part will be follow once you are an established member here because you can't participate in the signature campaigns or offer a service here if you are complete newbie.
You cannot start earning by familiarizing only, one needs to join a campaign. And with the rank of @OP, I believe it will take him months before he can join the signature campaign we are mentioning. So I think it won't do any harm to join a county campaign specifically social media campaigns while learning the curves of cryptocurrency and this forum.
