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.

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.

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
