otherwise it will be your passion in a machine.
In other words, mining won’t be not much profitable at a small scale.
Second You should have a better place in where electriciy is cheap.Mean you have a space/room/house/flat in industrial area
In other words, you have access to free or really cheap electriciy.
If you have both thing then you can get capital return in maximum 6 months.
