My electricity cost is higher than $0.2/kWh, so I do not mine. It is not profitable at all for me.
there is some profit you can do with a s7, a s7 can produce almost one btc, now a little less because of the recent diff increase, 0.75, which is $360
at 0.2 electricity your consumption per month is $180, so your net profit is still $180 per month
Looking at calculators, it looks like at the CURRENT rate, with zero electricity, break-even would be 11 months. Starting next month, that jumps up to 13-14 months. The next month it jumps up to 17 months, and this pattern continues. The chances of breaking even are almost non-existent, especially when you consider how quickly new hardware is being created/added.
no , don't fall for the "% diff increase each month", it's not working like that, the diff will settle at the same ratio as it was before, there will be no always the same increase as the last one
so the next diff increase will not be + 13% or something, but much lower, and with free electricity your earning would be $360 a month which mean 5 months roi not 11, S7 cost only 3 btc on bitman
But what's the guarantee that after halving takes place, the profitability will be the same???
Even if the calculators ain't right, we can't assume exactly as to what we will be getting in the future based on the uncertainty it possesses...
nothing, but if the demand remain the same, it will be profitable for the miners to mine, this is certain, the price already increase 2x, which is exactly what you need to face the halving
the efficiency will take care of the diff increase
