You can get bitcoin from faucet but the income is slow, but you can still earn more and faster income from signature campaign and social campaign, I think by participating in campaign is the best way to get btc from online.
This is the easiest way and no investment required to earn bitcoins. Some members joined here because of signature campaigns. The only thing that you need is patience and if you can wait till you ranked up and can now join on sig campaigns.
Yes having a high ranking here is very profitable if it can join in the signature campaign, but I have not been interested to apply for our signature campaign now for a reason.
