Who said, said that mining is not profitable?
I mine LTC with TITANs and BTC with Antminers S9
My last month's electricity consumption total in two places was 3267 euro. (This is with my home electricity cost. Hot water, cooking, etc. )
last month BTC mining result was 9.55 BTC (22 x S9)
and 600 LTC ( at the moment 2200-2300 Mhz)
After deducting the cost of electricity at least 7 BTC month for cover the investment .
U forgot to factor in equipment cost, which obviously isn't little with the size of operation ur running now...
After re-doing calculating that in ( cost spread over 12 month till bep,) net profit is deduced.
If you read again, you will see that I did not calculate profits.
It is more than 7 BTC in month, is that will repay the investment.
S9 price was at the beginning 2300 USD
11 x 2300 =25300 USD
Add another 12 pc about the same amount of money and get 50 600 USD for23x S9 miners.
I got my first 11x S9 over three months ago.
after the halving until today all my S9 miners have mined total 18,7 BTC
However, for 11x S9 there still were 3 weeks prior to the halving, which came 2 times more BTC .
So it was still 0,3 BTC per day + 600 LTC per month, only electricity went less.
So in the last three months has come to pay back the investment total at least 21 BTC
With today's prices, this is 13 125 USD, by doing this with a year 52 500 USD which almost covers S9 investment.
After 9 months from now i still have at least 15 working S9 and 1800 Mhz Titans.
Their sales should cover TITANS purchase price.
So, in 12 months, I have recouped the investment .. But TITANs have mined much longer than last three months.
Thanks for replying to my question tupsu.
Still u managed to neglect electricity cost ( no matter how small that might be where u at) but I get the bigger picture you're trying to paint here and let me tell u: it looks good :-)
However I have another technical question pertaining to ur setup and consequently to the given calculation above. Why not connect ur miners to a switch and through to 1 central PC ( or two ) instead of 11 PC ( if I understood u correctly )?
I believe there are certain mining softwares that enables u to monitor and supervise miners' work from a single station. Not just cheaper but more efficient and cost effective.
Thanks again for sharing this with us and wish u good luck with ur operation.
