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 .
