At this stage I will never prefer to quit my job for bitcoins as bitcoin doesnt promise us the level of security and stability that we always look for.
Me too I'm not going to quit my job but not with bitcoins but for my real job and both of them I don't prefer to quit both of them.
As long as it is giving me profit regardless the amount that I'm earning with it I don't care it is important to get profit from it.
So, I suggest don't quit any of them.
