I think signature campaign is the most viable job here for individual who does not posses the skills which are in demand in the online world like programming. If you understand bitcoin it would be easy for you to join the campaign available here and it would help you to understand more on the necessary information you need to learn to start a most advance job like trading.
agree with you signature campaign is the most popular way to earning bitcoin at this momen, im sure more than 50% of bitcointalk user do signature campaign.
