1000kwh in a month they are 1500w per hour of consumption, 1,5x24x30 approximately 1000, on that power there are some asic but a little dated, in a month you would not return to any investment.
I disagree the L3+ burns 750 watts
2 of them do 1500 watts.
2 of them earn about 3 usd a day
90 usd a month
they merge mine ltc and doge
also a s17 pro set on low will do 1200 watts which is 1.2 x 24 x 30 = 864 kwatts
it will do 40th which is 40 x .063 = 2.52 usd a day or $75.20 usd a month
the key is what does he pay for his power
If I understand the author's post correctly, then 1500w per hour is free. 2 asics for litecoin will give about 100 dollars of profit per month, but he will have to deal with noise. This is not such a large amount of profit now, but if you do not sell coins, then perhaps there will be more profit.
