A few months ago I was also totally new to bitcoin, and there was no any idea to me that how to earn bitcoin even i do not have idea that how people are earning some amount of bitcoin in signature campaigns and I even did not have any bitcoin wallet, but I started to search on this forum and with that I continued to search on google about bitcoin and about bitcointalk.org and within a month or less I learned all about bitcoin and now I am earning a good amount of bitcoin from here in this forum and from a number of tasks online available.
