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.
