How can people have that much khs? They got like 100 videocards or what?
Yeah, why not? I was talking to a guy last night with 60.
120MH on this though is much more than 100. An R9 290 does about 400KH, so it's 300+ GPUs, still, not a big investment really in the grand scheme of things - maybe $150k worth of hardware, plus unless you were already based there you'd have to rent some space with good power and HVAC, but it's small potatoes in the investments game.
