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?
First you need to read and learn about Bitcoin, then if you have already knowledge about Bitcoin you can join any Bounty Campaign and it is better if you are a jr. member or member before you join in a campaign that is one of the requirements to join. There are two kinds of earning coins, first is Bitcoin and the other is altcoins. It is hard to join in a bounty campaign that gives direct Bitcoin, so much better to join first in altcoins, it is easier to join.
