- buy BTC (NOT FREE)
- earn BTC by doing some work (there were a couple captcha entry jobs that payed $8 for 10.000 captchas if i remember correct)
- earn BTC by monetizing your skills (pretty hard, unless you have really unique skills)
- earn BTC by playing games (for example: flappy birds pays 600-ish satoshi's for every game you win, 200 times a day)
- use faucets: don't expect to make more than $0.5/hour
- join a signature campaign on this forum
But being to new you won't make much joining one so early.
I only made $0.03 for 20 posts

you're doing something wrong, because with 64block for example you can get 50k satoshi per post, x20 this is 1M satoshi, which is $2.768 and not 0.03
This is for Advertiser panel signature campaign only that was the first payment I got from them. Not the whole signature just the side where avatar should be if I was sr. or hero. That pays very low I think 0.000025btc per post, I can't remember but was just as a test phase(they said they will pay for last 2 weeks-60 posts) since my permanent signature campaign is what I am more concerned with but they don't have advertiser panel signage at the moment so it was going to be left bare anyways.

So why not.
Received payment of 0.001475btc just now so I was mistaken by the transaction that I received probably from a faucet(the sig campaign has not updated their user log in over a year

), so $0.39

Still very little compared to most.
