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.
it seems that you are talking about those people who are working after their dayjob.
In anycase, this is your and theirs decision, yes it was and is still a risk, you re risking with your time and energy. it is up to everyone of us to take that risk or not.
