Earning free bitcoin can be as example done by doing signature campaigns its easy and also very nice to do because you are learning from it.
but it can not be done by a newbie. means you need at least 2 weeks prior to joining to the signature campaign, because the minimum rank to join is a junior member
actual faucet is also a great free method
Yes newbie cannot join to the other signature campaign they have campaign accepts newbie but look at the pay rate per post it is very low . Jr member is the time to join in campaign you can earn bitcoin you need only 30activity. I don't recommend faucet because the payout is very low . like the others they work 2 days to faucet but look at payout its not 0.001 I think 0.0001 . your wasting your time to the faucet why .? Your electricity , internet and your time . so wait to rank up your account and then join to the signature campaign follow the rules and expect the good payout .
