Actually it depends into our life's situation. Probably if we have already work and we wanted to join or participating in campaigns therefore we must put or save a time for it so we can have extra income or profit and by that for sure it will be a good additional source of income. However, it can be also doing for a full time if we are jobless we can do it for a long time. Maybe 8 hrs. or more in every single day so it can gives as much more benefits and profits that can really helps to us in our financial aspects.
