This forum does allow to earn from social signatures using facebook and twiter, besides those you can join the signatures for posting, with this earnings you can invest at Ico or start trading. I did started with faucets some years ago and nowadays i use my signature earnings a part to trade and im saving the other part for the future.
there are many ways to earn bitcoin there are services that allow payment thru bitcoin and if you are traders there are platform that can suites your trading skills to earn more, investing sites are good if it will run for a long term not to scam people and the last thing is in this forum that you can earn if you join the signature campaign.
In my opinion joining a long term project will be better if your going to work on a campaign because the salary or payment will be depending on the stakes that has been accumulated. Then before starting to apply,Try to look for a campaign that will assign a salary percentage depending on the ico funds that will be gained.
