The current state of the Bitmain L3+ in the current ASIC and CRYPTO Universe.
Now
----
9/27/19 from
www.litecoinpool.org/calc a free LTC mining pool that has NO fee and pays out at 103%.
At 500mh and 800 watts at 10c kWh and at the current price of $55 per LTC. (This would be a bit better if you underclocked the L3+ units).
Comes to: (see below) NEGATIVE -$37.90 LOSS per month per L3+.
24 hours 0.01194157 LTC 0.66 USD 1.92 USD -1.26 USD
7 days 0.08359097 LTC 4.60 USD 13.44 USD -8.84 USD
30 days 0.35824702 LTC 19.70 USD 57.60 USD -37.90 USD
Future
------
Again, using
www.litecoinpool.org/calc as a guide. (Feel free to put in your own numbers on this calculator for LTC price/electric/underclock or whatever).
To make a profit using the same info as above and current difficulty and adjusting the price to that you at least break even would require
that LTC be at $161.00 LTC price. (Also remember if at that price difficulty would also go up likely with all L3+'s turned back on...but I'm using the same difficulty as today)
Again, 500mh 800 watts at 10c kWh at the current price of $161 per LTC. (This again would be better if you managed to underclock the L3+ units).
Comes to: (see below) POSITIVE 8c profit GAIN per month per L3+.
Expected Rewards Costs Net Profit
24 hours 0.01194157 LTC 1.92 USD 1.92 USD 0.00 USD
7 days 0.08359097 LTC 13.46 USD 13.44 USD 0.02 USD
30 days 0.35824702 LTC 57.68 USD 57.60 USD 0.08 USD
So from what I can tell you'd need $200 LTC almost immediately to even turn the L3+ units back on, due to the increase in hash-rate of everyone turning these
L3+ beasties back on. (Including my stuff).
So basically we are utterly screwed. And 'triply" so at $55 LTC prices. The boat has sunk. We need 3x the current price to basically make about 8c per L3+ per month!
All L3+'s have sunk. They, also are about IMHO 65% to75% of all scrypt-pow miners in the world, from what I can tell from Bitmain.
Complete and utter, as they say, 'miner capitulation' indeed. As an aside, this is pretty much the same issue as far as percentage of miners and price for Bitmain BTC miners the S9's.
So use your miners for 'nice' ASIC 'shelf art', in that as of now, that is all they are good for. Novelty shelf art indeed.
