The first time i heard about bitcoin was from my friend who is also a bitcoin user. He told me about bitcoins and how it works as far as he knows. Although we are both newbie at that time, we only had limited knowledge and backgroud about bitcoin it self. This however gives us a little bit disadvantage because we don't quite know all the possibilities that could happen if we continue using bitcoins. He also knew that we could earn money in terms of bitcoin just by joining campaigns.
