What miner is most profitable at 0.01 usd/kwh ?

[Carlus]

Hello,

I want to start a bigger mining farm exploiting my cheap access to electricity. Which miner is most profitable at 0.01 usd/kwh? I mean, where you get most bang for the buck.


I have been looking at buying 100-200 L3+ miners, as i found them to be more profitable than the newer s19 machines for example for the same amount of money.

For 100 L3+ miners, my costs would be 0.01 usd/kwh + 300 usd/month (Cost of housing them) + 700 usd/month (Electric) all amounts are approximate.

I estabished contacts with a big reputable Chinese seller and after a lot of discussion back and forth, we agreed on 6000 usd for 100 L3+ miners. Every machine will be tested before sending it, shipping costs will be about 800-1200 usd, cheapest and slowest option. Is this a good deal? Or would you guys propose another miner?

Something that worries me a little bit is how the profits will look like after LTC will be halved, that is going to happen soon. And Im worried if this will make my setup unprofitable?

Maybe there is another miner out there, that is quite cheap right now to buy due to high watt usage, but which can be profitable at low electric costs?

Best regards all, will be happy to receive any advice.

Whether it's $0.01/kWh, $0.05/kWh or something else, the general answer is miner with best energy efficiency. Since you ask on Bitcoin mining board, people usually would say Antminer S19 and it's variant (S19 XP, S19k Pro, etc.). But since you mention Scrypt ASIC miner (which i'm not familiar with), you might want to visit https://www.asicminervalue.com/ as initial reference.

The forever question for cheap power is how do I blend my gear to make good money.

A) accept perfection of your choice to be impossible.
B) determine how much power you have
C) determine how much cooling you have.

100 l3+ = 100 x 800 watts or 80kwatts that is about 275000 BTU.

I can assure you there are downsides to doing 100 of them
1) they take up space
2) they take time to manage.

I suggest a blend of gear.

(l3+)(m30)(l3+)(m30)

this would be 20 m30 and 20 L3+

or 20 x 3300 = 66000 watts for what's miner
and 20 x 800 = 16000 watts for L3+

same power only 40 units not 100

and the L3+ act as coolers for the m30 gear.

cost is more 20 x 1200 = 24000
and 20 x 75 = 1500

maybe 25500

if not acceptable

bump the L3+ to 40 say 3000
drop the m30 to 10 say 12000

15000 total outlay


much better way to play the game.

Thanks for your advice

But its not really applicable for my situation. For example ROI with L3+ miners will be about 4 months. While ROI on the most energy efficient s19 miner will be many more months than that.

Also, if my budget is 7000 usd total. How many s19 miners can i afford? (Or L7) Not many. I find that I can make much more profit with a few dozen L3+ than with one or two newest most energy efficient machines. For example 100 units of L3+ will give me about 4000 usd profit a month. While 2-3 s19 will only give me like 1200 usd i think ?

Asicminervalue is a great website and I used it before But its still a bit tricky to find the most profitable machine to run (Including purchasing cost and ROI and so on) on my electric cost. Thats why im asking here, maybe someone here faced the same issue and found the perfect miner.

Thank you so much for taking your time to write a well put answer Appreciate it.

A) So yeah, im pretty much at this point I think haha.
B) I propably have access to a few megawatts  I think. I live next to a hydropower dam so it wouldnt be too expensive to connect additional powerlines either I believe.
C) I live in a cold place, and I already have connected cooling tunnels to lead warm air outside. I also have a pretty large garage and an outside shed. So these places are naturally pretty damn cold.

1) Yes they will take lots of space..
2) About management, I already set up 10 of them at home already. And I was able to automatize everything. So that I dont need to touch anything except keep the internet access on and power on. This is how I got the idea to get a 100 of them. Because they literally take 0 management from my side. They boot automatically and start mining to my nicehash account. I also ofcourse have the 10 I currently have running connected to Hiveon.  Or do you mean repairs maybe? In that case yes, I dont have any knowldedge in repairs of these machines.

Exactly I was looking into making a blend of some sort. And thought this could maybe be better generally and not fully rely on LTC mining but maybe bitcoin mining also. But I was looking at the ROI for the m30 whatsminer and the ROI is many more months than the L3+ or?

I can get the l3+ for about 60 usd a piece. I think the cheapest M30 Whatsminer I found through Chinese retailer was like 1000 usd. Idk, what do you think? Its still worth it to buy M30? On the other hand, the M30 takes up much less space and less time to set up ( Due to needing fewer units for the same hashpower)

Im not quite sure what you mean here " the L3+ act as coolers for the m30 gear." how?

Do you think the M30 is more future proof than L3+ ?

Your idea is pretty good I would say, I will think about it and do the math behind it

Best regards

[philipma1957]

The m30 is more future proof than the L3+

but is costs more. (as most believe it is better for the next 24 months )

I like both and own both and will continue to mine both.

You can spend 7000. get 100 L3+ and 1 m30 cost = 7200 yeah I got you over budget.

You will make good money on the L3+ for 60-70 days after that it gets murky (due to ½ ing)

The m30 will take a long time to get initial money back.

But right now 1 m30 burns 3200 watts

4 L3+ burn 3200 watts

zero power cost

a 98th m30 makes 98 x 7.5 cents  and 7.35 a day ½ in over 240 days earnings may drop  with ½ ing

4 L3= make 4 x 1 dollar  so  4 a day  ½ ing in 60-70 days earnings  may drop  a lot with ½ ing

So that higher cost builds in the the 2  ½ ings and charges more for the m30.

I am trying to blend your risk by adding in a m30.

your cheap power pushes you to the l3+
your low cost and 7000 budget pushes you to the l3+

all good but being diverse helps I suggest an m30 it does fit your budget for 1.

One minute. When is litecoin halving?
https://minerstat.com/hardware/antminer-l3plus
Soon you will receive 40-50% less profit, and bitcoin also has less than a year before halving.
Check your calculations taking into account halving and ASIC delivery to you. Otherwise, you will get your asics right before the litecoin halving.

Also, if my budget is 7000 usd total. How many s19 miners can i afford? (Or L7) Not many. I find that I can make much more profit with a few dozen L3+ than with one or two newest most energy efficient machines. For example 100 units of L3+ will give me about 4000 usd profit a month. While 2-3 s19 will only give me like 1200 usd i think ?

This is for my thoughts and my opinion, Maybe what you say is right that you can make money there with a few dozen L3+ miners compared to 1 or 2 S19 miners. From what I know, L3+ is cheaper compared to S19 miner, although it is weaker and older, unlike S19 miner which is better and newer, that's why it is more expensive than L3+ miners.

       Now, regarding your question that you have 7000$, my answer to you is that with this amount that you have, my rough estimation here is that you can buy from 7-10 L3+ miners and I estimate the hashrate that you can get here is between 400--510TH/s. And the chances you can earn here are probably playing more or less 1000$.

If you buy S19 miners, my rough estimation that you can get hashrate is more or less 110TH/s which with the difficulty and value of bitcoin it is possible that you can earn around 2000$ I guess . So if you're looking for good miners I suggest that I think it's better to buy 1-3 of the S19 miners.

0.01 for electricity very good.there is couple of thing i would be thinking. 1 how long ltc will be at current price what is minimum price will be ltc for long time. Right now it looks like l3 gives 1.22-0.2 1$ per day. Would it be funny if it goes to 0.4-0.5 per day? If this ok for you then with 6k for 100hundred units it is very good deal even it sounds too good to be true.

This thread being in the altcoin section I'm surprised that people are focusing on ASIC information and not GPUs.  I would say if you want to know information about profitability then look to https://whattomine.com/ for a list of GPUs and algorithms that can also have electricity price entered into the equation.  With such a cheap price to pay for electricity, most likely it will be whatever you can get the most revenue from for the least amount of equipment purchase cost.

Did you even read the post?  OP has a quote for asic miners....

This statistic is better
https://www.hashrate.no/gpus
Today, even the newest video cards have a payback of 7-10 years, and old video cards will make you pay extra for electricity. Buying video cards will not bring profit.
I have some video cards left and for now I am set to turn off mining, and I advise beginners not to buy a GPU if you do not know the secret coins.

[philipma1957]

Read the whole thread.

He can get 100 L3+ for $6,000 which is a very good price.

But he is settled on a dead end short term miner. In the L3+

His power price is really cheap.

My issue is $ per watt.

The L3+ = 800 watts for 1 dollar in coins

the m30 = 3200 watts for 7 dollars in coins.

so 4 L3+ = 3200 watts for 4 dollars take more space and have a very short future due to 1/2 ing in 60-70 days.

the m30 = 3200 watts for 7 dollar a day takes less space and has a 200 + day till 1/2 ing it is the more valuable unit.

he could buy his 100 l3+

and 1 m30

pay 7200 which is his budget.

he could list the l3+ slow on eBay to recover more money and slowly convert all his shit to m30 units.

So while it is not all mining bitcoin now. by Jan he would be 100% m30 and all BTC

there is no legal 0.01$ electric price in the world, if exist there is only quota based on. even you make your own electric, 0.01 is hardly to achieve, solar only produce 0.03 in terms cost of facility/25 years maintenance. hydro can achieve 0.01. but to be honest, 0.01 is just like free electric, you can throw anything without any loss even a decade old hardware

I agree with you that there are no such cheap prices for mining companies, but nuclear power can give 2 cents when building a modern power plant. Although in Russia, in places where there is hydropower, there is also a tariff of 2 cents for the population, but consumption is limited there.

There is no possibility for such electricity price as you say but let's say the OP has it.The best bang would surely be L7 Antminer at 9500 Mhsh for Litecoin plus Doge mining.I think it is better to have this rather than other devices and have fewer of them,as 1 of them equals to 11-12 L3+ or even more than them,so rather than going with 100 such L3 Antminers it would be great to go with 8-9 L7 Antminers which are managed in a much easier way rather than to manage 100 devices.

At this price of electricity, any ASIC will be profitable after the halving of Litecoin and Bitcoin. It is not necessary to buy asics for one algorithm, you can buy asics for both bitcoin and litecoin to reduce risks if the price of one of the coins rises more.

In this case we both know that the one price which will skyrocket more is absolutely Bitcoin compared to Litecoin and in such context it would be great for the OP to buy any Bitcoin miner as overall this will bring him much more profit than a Litecoin miner.However this depends on the dollar amount that each miner does,if the Litecoin L7 produces more dollars then it still is a good option as the Litecoin or Dogecoin that this miners mine can be converted to Bitcoin and be in bigger profit.In either case the OP does not lose anything as that 0.01 electricity price is unbeatable.

Every machine will be tested before sending it, shipping costs will be about 800-1200 usd, cheapest and slowest option. Is this a good deal? Or would you guys propose another miner?

Something that worries me a little bit is how the profits will look like after LTC will be halved, that is going to happen soon. And Im worried if this will make my setup unprofitable?

Maybe there is another miner out there, that is quite cheap right now to buy due to high watt usage, but which can be profitable at low electric costs?

Best regards all, will be happy to receive any advice.

there is no legal 0.01$ electric price in the world, if exist there is only quota based on. even you make your own electric, 0.01 is hardly to achieve, solar only produce 0.03 in terms cost of facility/25 years maintenance. hydro can achieve 0.01. but to be honest, 0.01 is just like free electric, you can throw anything without any loss even a decade old hardware  

I agree with you that there are no such cheap prices for mining companies, but nuclear power can give 2 cents when building a modern power plant. Although in Russia, in places where there is hydropower, there is also a tariff of 2 cents for the population, but consumption is limited there.

There is no possibility for such electricity price as you say but let's say the OP has it.The best bang would surely be L7 Antminer at 9500 Mhsh for Litecoin plus Doge mining.I think it is better to have this rather than other devices and have fewer of them,as 1 of them equals to 11-12 L3+ or even more than them,so rather than going with 100 such L3 Antminers it would be great to go with 8-9 L7 Antminers which are managed in a much easier way rather than to manage 100 devices.

At this price of electricity, any ASIC will be profitable after the halving of Litecoin and Bitcoin. It is not necessary to buy asics for one algorithm, you can buy asics for both bitcoin and litecoin to reduce risks if the price of one of the coins rises more.

In this case we both know that the one price which will skyrocket more is absolutely Bitcoin compared to Litecoin and in such context it would be great for the OP to buy any Bitcoin miner as overall this will bring him much more profit than a Litecoin miner.However this depends on the dollar amount that each miner does,if the Litecoin L7 produces more dollars then it still is a good option as the Litecoin or Dogecoin that this miners mine can be converted to Bitcoin and be in bigger profit.In either case the OP does not lose anything as that 0.01 electricity price is unbeatable.

Litecoin halving will be earlier, so when choosing an ASIC, you need to take into account the profit after halving, which will be in about 10 days. But with any option, you can even buy old asics for bitcoin with a hashrate of 40-60 terahash with discounts if you need to use the entire power limit.
