It's actually dropping a lot...
BTC is getting closer to the $1 per t/hash of network power I guess was a fair price at the lower end, $2 per t/hash at the high end.
LTC is difficult now, playing with some calculators agian $/KWH are seroulsly coming back into play again between LTC and BTC. Becasue of the lower LTC/USD price and LTC/BTC price they are telling me that it's now more profitable to mine BTC @ 600m/hash drawing 220wats or less (unvolt, underclock memory) than the 630 k/hash for LTC drawing 300 watts due to slight overvolting to maximise core 1050/memory 1500 on my 7950.
Will have some playing to do this weekend, still new to this and it looks like mining may have to be swiched from LTC to BTC each few days until prices settle again and it becomes clear which makes best $$$.
On Monday this week LTC was aclear winner as enrergy costs where almost factored out, not so clear now.
