For me its like part time work and most of the people doing this as a professional work , some are doing like business and even some are going like gill time job , But whatever the reason bounties and signature campaigns gave much financial liberty for me . Even I could able to afford some of my wishes.
Although doing any work in this bounty, I just summarize one thing that I do for money, I really need money in my life and I try to make money at all possible, passion I really do not have, maybe because my life is poor so I have to accept the trade.
