Its good to realise that a lot individuals like you are very interested in bitcoin, to the extend that they end up having the thought of earning some for themselves. Since you are a newbie, unfortunately you cannot participate in any signature campaigns. You will need to rank up to at least jnr, this means always being active on the forum. In the meantime you can earn through social media campaigns(only if you are having a lager reach/audience), faucets/refferals, mining or design for bitcoins.
