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?
If you know something about crypto you could write posts on this forum and earn some money by doing that, just find some interesting campaign for you and enter it, good luck.
