i prefer both, because in this way you can earn more and you well know the matters outside from bitcoin. bitcoin just need your small part of attention, this attention contain focus and strategy.
Agreed, earning bitcoin does not mean that you need to quit your job to be able to do so, the wise thing to do is work throughout the days of he week like normal people take an hour or tow when you get back home to earn bitcoin and on the weekends you can focus more on it, that way you win from both sides.
