I use www.litecoinpool.org/calc as my 'low' baseline on what my miners are making. I do get say 10-15% more on prohashing. But as a
rule of thumb and watching the trend of difficulty go up and profits go down it serves its purpose.

As of today, 10/08/17 at 1:38am CST USA...I have the following

At 12c kWh prices for electric and a price currently of $52.69, (https://www.worldcoinindex.com/),  at this moment, I get the following profits.


KNC Titan $4.62 per day.

Below $4.61 per day in LTC profits. Below is for a 300mh KNC Titan (4 cube) at 1,250 watts.

                        Expected Rewards          Electric      Profit
24 hours   0.15583008 LTC   8.21 USD   3.60 USD   4.61 USD
7 days   1.09081055 LTC   57.47 USD   25.20 USD   32.27 USD
30 days   4.67490234 LTC   246.32 USD   108.00 USD   138.32 USD


Bitmain L3 is $5.69 per day.


Below $5.69 per day in LTC profits. Below is for a Bitmain L3 250mh at 400 watts.

                        Expected Rewards          Electric      Profit
24 hours   0.12985840 LTC   6.84 USD   1.15 USD   5.69 USD
7 days   0.90900879 LTC   47.90 USD   8.06 USD   39.83 USD
30 days   3.89575195 LTC   205.27 USD   34.56 USD   170.71 USD


Bitmain L3+ is $11.38 per day.

Below $11.38 per day in LTC profits. Below is for a Bitmain L3+ 500mh at 800 watts.

                        Expected Rewards          Electric      Profit
24 hours   0.25971680 LTC   13.68 USD   2.30 USD   11.38 USD
7 days   1.81801758 LTC   95.79 USD   16.13 USD   79.66 USD
30 days   7.79150391 LTC   410.53 USD   69.12 USD   341.41 USD


Again consolidated below, AGAIN, this date/time/etc (See beginning of this post)

KNC Titan $4.62 per day.

Bitmain L3 is $5.69 per day.

Bitmain L3+ is $11.38 per day.


So to recap...without some MAJOR price moves on LTC or scrypt pow (again the calcs used here are LTC only ..you will make more on multipool like prohashing)
we are gonna get messed up bad on this looming difficulty wave yet..and plow the surfboard into the beach.

So, will the price rise on pow-scrypt to compensate for difficulty or will our scrypt-pow miners of any flavor be doorstops below such a difficulty plateau
just out of reach for us to continue to run them say by Jan or Feb?

I hate my return to 2013 and 'newbie hopes' of the price rising to justify equipment..it is sooooooooo a fall back into those bad habits..but at this point
thems the breaks..price pump or equipment dump to doorstops on the horizon.

Again, note that the litecoinpool calculator is simply being used as the 'low' on what we can get. You will get more on multi-pools like prohashing.
But the above shows the 'bottom' on price per day imho.

Also, as far as I can tell there are still at least FOUR major dumps of Bitmain L3+ equipment and ONE major dump of the bw.com equipment that also dumps
in middle of November. So I would expect that at the present sideways price spread of LTC you would be looking at 1/2 of the profits I post here by say Dec 2017,
when all the pow-scrypt equip clears. More if Bitmain shoots even more out like toasters.

Thus my posting of the above this time/this date/etc....

We will be the first to know I guess.....(shudder)

later






Well first of good post lol   Its rare to get some rational thinking in this thread Cheesy

I see it the same way, but then again a little less worrying.   The Titans are old and that they still produce anything at 12c is mindblowing. The L3 and L3+ will be still profitable when halved.

Now calculating in that as a business you can deduct your running costs from profits and the sale price of equipment, once the electricity is more than your income, eases it a little bit.

The Titans will soon be gone giving a tiny bit of air to the network and once most 20c+ Miners face the reality they will sell the units to those who are able to run them on 3-6c/kwh


It's pretty much a wash. I cant make a real loss when I can deduct my costs and with the prices for old equipment, I don't worry at all.

I just saw a A4 getting bids of 1600€+ on ebay Cheesy

Just received an L3+ ... buddy of mine received 15 of them...
While mine runs decently, some of his eventually get x's in the chip list as they run... is this a widespread problem?

Im entertaining ideas for firmware enhancement =)

I have a few L3+, one of them went into the XXX.. mode once, a power-down and cool-out for 30mins and following restart fixed it so far.
What I noticed is that the HW version seems to matter. I have one with 1.0.1.2 which yet has to make a single HW error after weeks. The other ones with 1.0.1.1 produce regular HW errors, though hashrate seems to be similar over all in the long run.

In my experience the difference (whatever it is) between 1.0.1.1 and 1.0.1.2 seems to matter.

I have one with 1.0.1.1 and temp is quite high during the day. after over 24 hours, one or 2 boards will produces XXX in between.

However, 1.0.1.3 is better of producing HW errors and XXX, but it seems that it will auto-restart 2x a day.

Nicehash seems to be the best payout for me at 16.7$, can't be bothered with the other pools anymore.

Tried to insert a screenshot but it doesn't seem to work.

good that it worked out fine for u. Where i'm, the nearest server is HK  and the result is not better than zpool.ca
The core reason is that Nicehash is not a pool per say, its a service.

- demand/supply drives the price. the payment amount is direct driven by the buy price of the order your filling.
- only valid share calculated to your profitability.
- downtime on your miner means u get lesser shares submission  aka penalty
- direct deposit of earning to your local NH wallet
- you'll know in minutes how much money you'll make a day

not too, my hardware 1.0.1.3 just better producing HW error,, board 2 5day give 1k HW error but not XXX,, it just because electrical and bad connection

All of my 1.0.1.1 boards have all burned up and Asic Board 0 aka the left board is shot on all of them. 1 of them only sees 20x asics per card and does 75mh/s under clocked to 154mhz... Bitmain quality went to shit.

Can't I am waiting to hear if I can get a replacement board for 2 of them and 4 for the other. They are out of warranty at this point. All the others I have have been doing great some I actually got OC to 475mhs doing 620mh/s (warranty is gone so might as well OC them now since the difficulty is going to go up when more l3+'s land. The extra $5 per machine adds up when you have a dozen.


Also for those that want to see this is how I have 9 L3+'s going right now



Stacked once and have them next to eachother with PSU's separating block of 4. Behind the rack there is a window. I have approx 20 more miners coming and I think I need a longer shelf than this current one. Otherwise I will have three shelves loaded with these things. I have d3's and s9's coming. I have 3 fans moving around around in this room sucking in from a window and blowing out. It should work until winter is over then I need to build a shed for these things.

You overclock your machines and run them in that kind of environment whilst blaming Bitmain quality for your boards burning up?...

Well let me add some details. Those 3 that had issues had issues before OC. Once they shit the bed I said screw it and I decided to overclock all of them and they have been going fine for a few months now like so.

That kind of environment?? What are you talking about. The room is at about 72F ambient temperature in the north. Once it gets colder the room will easily maintain a 50-60F temperature. The cards are running at 51C... I have very very good airflow and cooling setup in that room for what I have right now. Most peoples L3+ Run in the mid to high 60C even at stock...

The biggest thing to getting the airflow right is a thermal camera and make adjustment and check back in a few minutes until it's perfect. There are 2 windows on both side of that room which is below ground. One window on the far side sucks in air has a 584CFM Fan along with a few others and then there is an exhaust shutter style fan on the others that all the asics blow air over too. If you put your hand to either window there is a constant blast of air being sucked in or pushed out

Ah ok. Yeah if they had issues before the OC then that's on Bitmain, however most people really don't advise overclocking them, although the extra profits are nice.

Lucky you that you're in the north! 72F is nice, I just cringe when I see nearly 7,000 watts of electricity surrounded by cardboard.

What is more funny the 3 that acted up were all in the same shipment. They also have different fans that do not go the same speed and had issues throughout. I think bitmain sent out some lemons.

Except electricity is about 14 cents. I mean it's 6 cents... but there is 8 cents in delivery fees...

In the spring I am going to buy a shed and retro fit it to do some crazy shit with these things if I can figure it out. Since we can get some 90F Summer heat or hotter. Was thinking I could do that chinese mine idea and add humidity to drop the temperature at like 20% humidity but I am not sure if that is to high as that is a cheap easy way to drop temps aside from tons of fans.


as for now

The biggest thing to getting the airflow right is a thermal camera and make adjustment and check back in a few minutes until it's perfect. There are 2 windows on both side of that room which is below ground. One window on the far side sucks in air has a 584CFM Fan along with a few others and then there is an exhaust shutter style fan on the others that all the asics blow air over too. If you put your hand to either window there is a constant blast of air being sucked in or pushed out

Yeah, airflow is key. When I receive mine in 2-3 weeks I'll be putting them in a room indoors. I can't rent a warehouse or anything like that because it gets too hot and humid here in FL, so they're in a much better environment indoors, it would cost too much to keep them cool enough in a warehouse. All of their hot exhaust air will be vented directly out of the room via a window so no hot air can escape back into the room, air will be brought into the room via the rest of the house (another benefit of using a room in the house), and a portable AC will be set up in the room to keep temps down from any heat that the miners generate which may slip through and don't get vented out of the room.

I was thinking of doing this setup with my L3/S9/D3

Figure all the miners blow inwards hot air vents out and the cold air come around the miners. And the exhaust into a closed hot room.

Figure all the miners blow inwards hot air vents out and the cold air come around the miners. And the exhaust into a closed hot room.

Yeah, essentially just a hot/cold isle, same as what I have planned but this video is on a much larger scale. I'm going to put the miners on a rack, have the back of the rack facing the window, and put a tarp up on either side of the rack and one laid over the top to direct the hot exhaust air out of the window. This way the hot exhaust air is kept separate from the rest of the room and the hot air isn't recirculated into the miners intakes. Very optimal setup.
