I know that there are other members here working day and night doing bounty campaigns. But i think that doing bounty campaigns is not worth it especially if you had a lot of work during the day. Some are just boasting on their bounty campaign earning wherein fact maybe because they are lucky to receive those awards but somehow do not wish that you could be like them because some of the ICO project that you will going to work will not give bounty rewards and some of it will fail, or just pause. So no reason for sleeping late at night.
I think the better option is to have a decently paid job and then invest. Bounty hunters are second rated people, and they are often treated like that also. Bounty hunting is most of the time like squeezing juice from dried fruit. Although once in a while, just once in a while, you may hit the jackpot and be rewarded nicely.
Of course it also depends where you live. An Indian or African will be happier with his bounty rewards than a western European, simply because life in Europe is more expensive than in Africa or Asia (in general).
