I do not agree that gaining bitcoins have any effect on the physical and online jobs. Currently, the world's population is ten times more than the available jobs. So I think bitcoin can even help reduce unemployment and overdependence rate. If someone leaves his/her job because of bitcoin, another will occupy. The bitcoin holder can also be an employer. Bitcoin possessors also buy from the market so if everybody is not working, where will they buy from? I think bitcoin would rather help sustain life.
Very true, there is already scarcity of jobs. We need more opportunities like crypto to fill the gap.
