This is my way too, I tried to give my best in my job and to grow on my field and profession ,and after work I focus on bitcoin, and when there's some time left. I don't think there's a need to make stop our job ,we just need to do extra effort and time management.
Bitcoin can be a source of income, just by using free time, that's enough. Without the need to sacrifice work, we can still generate revenue from bitcoin.
i agree with you that bitcoin can be manage in free time it doesn't need to leave your jobs and work all day in bitcoin, i think part time is very good for bitcoin to be a source of income and in this era people always do effort to earn extra money, so if you have chance to have your real jobs and also doing work in bitcoin then i don't think to leave real jobs.
