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.
Sleeping late at night maybe because of bounty campaign is worth it ofcourse. Yet we have rules in bounty campaigns. Here in bitcointalk.org, in its signature campaign, there are limits to be done per day. Maybe if you do it earlier than what time you usually do it, then you do not have to sleep late at night. Following the rules and regulation and become perfectionist to yourself will make you even better in doing your job here in cryptocurrency world.
