Btw: I pay 0.265USD/kWh and I'm still at 140%R.O.I. (after all exchange fees, based only on electricity costs, let's keep hardware out of that equation, lol);
But not with ETH. (Don't ask. I won't tell.)
I have still 2 to 3 weeks left before turning off the rigs. What will indeed happen for all of us at some point in the future.
If i were you i would turn off right now cause pools usually steal 30% or more profit from the calculation, be aware of that. Bitcoin crashing is fine cause asic companies would never lose profitability now gpu miners are losing everyday as eth price crashes.
