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?
Earning Bitcoin here in forum is hard nowadays, you need to become higher ranks to join a campaign and you need lots of knowledge about Bitcoin to participate like signature campaign because you can only post selected boards and it must be high quality. There is an alternate to earn Bitcoin, you can join bounty campaign in alt coins and just convert it to Bitcoin.
