this is how i started and im earning currently 0.2 - 0.4 btc per month

first are the faucets,you need to have lots and lots of refs to earn something you can earn with 50 - 100 active refs maybe 0.01 btc per month

second gambling faucets,here you just try your luck with maybe 500 - 2000 satoshi per minut to raise up to 100k sat or 200k sat and then cashout,you can earn around 0.02-0.1 from this!!if you cashout after every 100k or 200k

third is ofcourse signature campgain,you can earn here from 0.05 - 0.3 per month!!

try the first 2 until you get a good rank for a signature campagain!
