It depends on where you place Bitcoin. If you treat Bitcoin as a full-time job, you need to pay attention all the time, but if you invest it, you certainly won't put all your money in, so you don't need to keep watching.
Yeah it is good to use bitcoin as your additional source of income but dont leave your job for the sake of bitcoin, it allows high income as way of earning as it can be earn in your free time, nothing is to be worry at all. Market value use to rise and fall everything should be done with patience, at beginning age of investment try to invest small and limited money to bitcoin then after than increase your circle so it will not disturb you.
I agree that you shouldn't leave your job for earning online using bitcoin. Bitcoin is very volatile, it is still safe to have an expected income at the end of the month rather than praying for the bitcoin price to soar up high.
