I'm a newbie and honestly, bitcoin is new to me.. I just heard this few months ago from a friend who invested his own money. But from other friend told me that he earned bitcoin here in bitcointalk without investing money from his own pocket. Maybe some of you here can advise me what to do to earn bitcoin?
You can earn bitcoins here by participating in signature campaigns. You will be paid more if you have got higher rank.
How to earn higher rank? Is it just by writing posts? And signature campaigns? That sounds interesting.
