I think gambling is the most easiest way to earn more and more bitcoin in a short time, nut gambling needs a lot of experience and skills. Without these two you man lose your earnings because it is gambling. On the other hand I daily work for more than 5 hours but I cant make one bitcoin in the whole month. It is not an easy task. You will have to do some extra things like trading and bounty campaign.
