For me it is a simple choice. Sure I would want to earn a living with bitcoin. But let's face it. For most of us this is a dream and will reamin a dream.
Yes it will only remain a dream to have a stable income in bitcoin and doing an earning with it is not sustainable because of the lack of available work.
To earn a living with Bitcoin is really hard, because the value of Bitcoin is always changing so nobody will know what the value will be in the future and that is the problem.
Many people see Bitcoin as a bonus and that is the best thing that you can do with Bitcoin.
If you have a good job then continue with it, and try to earn from both of it, that will make your rich in quick time, only earning a living from bitcoin will be difficult.
