Hi, hope someone could steer me in the right direction.
I now have free electricity, but limited capital for equipment.
What is the cheapest “non profitable” asic?
I see the antminer s9 for around 60$, those are supposed to pull about 30$/month.
So it would pay for itself in 2 months, any other options that’s better in your opinion?
Most important factor is how fast the hardware pays for itself, considering free electricity and all.
Efficiency, noise etc, Idk about
