how long is the ROI on them , atm?
There are calculators for that... Simple google search would have given you a good guess.
Calculate around 200+ days given the low LTC price, the increasing diff and your electricity costs
Mine are doing a whopping 2.50 profit a day per machine (and mine are overclocked)
Using the free pool that pays at 101%
www.litecoinpool.org/calc calculator I get the following
At next months summer rate (April 2018) starting soon....of 12c kWh and $142 LTC price and 400w and 250mh an L3 gets below:
$1.79 per day for an L3.
24 hours 0.02073776 LTC 2.94 USD 1.15 USD 1.79 USD
7 days 0.14516432 LTC 20.61 USD 8.06 USD 12.55 USD
30 days 0.62213280 LTC 88.34 USD 34.56 USD 53.78 USD
$3.59 per day for an L3+.
At 12c kWh and 800w and 500mh and $142 LTC price an L3+ gets below:
24 hours 0.04147552 LTC 5.89 USD 2.30 USD 3.59 USD
7 days 0.29032864 LTC 41.23 USD 16.13 USD 25.10 USD
30 days 1.24426560 LTC 176.69 USD 69.12 USD 107.57 USD
At 12c kWh and 1250w and 300mh and $142 LTC price a KNC Titan gets below:
-$0.07 per day for a 300mh KNC Titan (Sob!)
24 hours 0.02488531 LTC 3.53 USD 3.60 USD -0.07 USD
7 days 0.17419718 LTC 24.74 USD 25.20 USD -0.46 USD
30 days 0.74655936 LTC 106.01 USD 108.00 USD -1.99 USD
So man, do we need a pump in price for all the above reasons. I expect another slash in price for the L3+ on the Bitmain site,
but being Bitmain (let them eat cake!) I could be wrong.
Damn, ugly out there in the Universe of Scrypt-Pow...applied to LTC anyway...
Yeah! L3+ mines only 3.59 LTC per day and profit falls very quickly. Don't know what's up, maybe too many mining rigs are mining so the difficulty went to the moon, but at such rate soon we'll mine for electricity only.
