New kid on the block?

[Somegory]

A new Bitcoin solo miner is on the block  



Meet the NerdQX this miner comes with 8th and it consumes 170watts from the wall and I think it's from NerdAxe makers too? I can't figure it out, but some miners already buying.



Although I feel like the other NerdAxe with 12TH and 200watt makes sense than this, power consumption wise, this is better because it's only 30watts more than this NerdQX, I just bring this for awareness purposes.

[Oshosondy]

Bitmain Ant miners that I can recommend for miners are S17, S17 Pro, or S17+. They are consuming between 1975 watts and 3040 watts of electricity.

A miner that is consuming 170 watt of electricity will be too small to mine bitcoin. It can not do the work for solo miners at all unless they are extremely lucky. Even solo miners will still connect more miners like S17 together or join hands together with another solo miners because they want to have high probability of mining a block.

Both of them supposed to be from same company NerdMiners. But a review i found says 8TH is in overclock mode.

If you care about energy efficiency, default mode makes more sense since ECO mode barely improve the efficiency.

NerdMiner NerdOCTAxe Rev 3.1 (12 Th/s) $340 and NerdMiner NerdOCTAxe (9.6 Th/s) $280. ​​
Both devices won't break even on regular mining, so they're only suitable for solo mining. I'd probably choose devices with 100 TH/s or higher, as the odds of winning in solo mining are significantly higher, but still very slim to win.

This miner was never intended for breaking even, I know that's not going to work, such miner is for solo mining, I should have included it that way, but expect readers to figure it out easily.

Solo mining is very difficult but never say never, it won't hurt trying, I only want people to be aware that this miner exists, some can't run a profitable miners that takes 2000+ power from the wall, they can prefer small miners like this one.

Solo mining on such devices is very easy because they work out of the box and have very low power consumption, but it's usually the sellers of these devices who make money in this business.
It's like the gold rush, when equipment sellers made a lot of money.
To profitably run an ASIC, electricity costs need to be 4-6 cents.

This NerdQX device doesn't make a lot of sense to be honest especially at its price point.

I recently acquired a NerdOctaxe V3.1 which runs 10TH @ 160W and it'll happily do 12TH @ 198Watts ~= 16.5W/TH if you don't mind the fans running at full speed.

I've just ordered two more to replace all of my Bitaxe Gamma 601's.


The price-point makes no sense

~$350-$400 for the NerdOctaxe V3.1 (10-12TH/s) Vs $650.00 for this NerdQX(4.8-8TH/s overclocked)

For the NerdQX 8TH overclocked so the ASIC's are pushed to their operating limits Vs 10TH NerdOctAxe with nominal clocking.


Talking of Bitaxes, you could buy 4 Bitaxe Gamma 601's at ~$70 each and achieve the same performance for $280


Nope. not for me thanks.

If it were less than $250 at that price it might just about be interesting, but $650+Shipping is a bad joke.

As hashrate increases, we'll soon reach the point where home devices for solo mining will consume 500 watts or more, and their hashrate will still be too low to find a block.
It's better to find an old Series 19 ASIC, get inexpensive power, and use it in its most energy-efficient mode for solo mining. This will yield 70-80 terahash, worth $150-200.

You're quite right.

I think we've already surpassed that point for home mining to be in with a reasonable chance.

Once I set-up my new OctAxes I'll be running around 480Watts for 30TH/s thankfully most of it is off solar and battery. Though I'll have to scale it back during the winter months.

When I first started solo mining the network diff was around 20T back in 2021 its now ~6.5 times that at 132T and its also clear that the diff is exponentially harder rather than being linear.

Network hash rate in Jan 2021 was around 145 EH/s today its around 950 EH/s and topped out late last year at around 1190 EH/s that's almost incomprehensible amounts of processing.

On the S19's BM1366 the problem is they're not as energy efficient as the BM1370 from the S21 series by 1.4-1.6 times and that makes a really big difference.

But int terms of hash per $ a used S19 for solo is probably a good starting point.

As a footnote, the two new OctAxes will be the last time I spend on any bitcoin mining kit. Its got to the point where this is last chance saloon for solo mining. Anything beyond 500W really isnt "home" mining any more especially with energy prices being what they are, I'm lucky enough to be able to off-set most of it with solar.

[philipma1957]

Right now I am pointing 180th at a solo pool

And 1 th at another
Guess which pool has a 300g share and which pool has a 22g share.

Hit the lone bitaxe set to only  800g on a down clock

Has the bigger share.

About 14x bigger than the 180th pool

The pool with 180th should make a block in about 95years.

The pool with bitaxe should take 17000 years

Never mind that the diff will rise  etc

BTW i can not afford to run 180th at home it will be turned down to 55th soon

$650 for NerdQX is crazy, where did you get this price from? You should check the price on AliExpress and some are offering free shipping too, the last time I checked the cheapest price for this miner it's around $265.

There is no way anyone is ever going to buy such for $650 unless people don't know what they are doing, NerdOctAxe price is valid as it's the same on AliExpress, $300+ to $400, and I believe it's better but having great options like NerdQX is not bad too.

BTW i can not afford to run 180th at home it will be turned down to 55th soon

You ever consider running the 55TH on solar panel and grid when the sun goes down? The problem with my country is unreliable grid power but it's cheap enough, only that the power is not stable.

[Nexus9090]

The pricing was taken from the originators website



https://ixtech.xyz/products/nerdqx-8th-bitcoin-home-miner


As far as I'm concerned buying stuff off Aliexpress is a no go especially for value items >$100. I bought a few Bitaxe gamma's from Aliexpress and regretted it as the build quality was awful.

As for the NerdQX as a miner it just doesn't make any sense given the plethora of other Bitaxe and NerdAxe models that are available with better pricing.

That doesn't surprise me to be honest. One of my bitaxes hit a 220G a couple of months back. The OctAxe has a best of 18G so far; but then I've not been running it that long.

Random is as random does!

Energy wise, 180TH from home must be costing a bit.

I've set myself a hard target with the 30TH and then I'm calling it a day. It'll get set-up in the garage and forgotten about; then it either wins or it doesn't.

Eventually in a year or two's time depending on how much the diff has gone up I'll make the decision to terminate mining BTC altogether and instead move over to BTC2 or BCH smaller rewards but its better than nothing.

Solar power is great, but in my country, I can sell electricity during the day for 2 cents and buy it in the evening for 5 cents. This is designed specifically to discourage people from mining and buying solar power equipment.
And an autonomous system with batteries won't always be cheap and profitable.

Solar power is great, but in my country, I can sell electricity during the day for 2 cents and buy it in the evening for 5 cents. This is designed specifically to discourage people from mining and buying solar power equipment.
And an autonomous system with batteries won't always be cheap and profitable.

My home runs completely on solar during the day with enough left over to charge the battery and feed back to the grid.

Typically it produces on a sunny day something in the region of 32KWH, over night the battery has a capacity of around 3.5KWH which is enough to get the house through the night typically though in winter it depletes quite quickly.

The only exceptions are days where its really cloudy and between October and March when daylight and sunshine is limited in the UK then its typically between 0-12KWH and very variable with the weather.

When I start running the new OAxes overnight it will probably deplete the battery before morning but the overlap will be small.

All of the excess unused gets fed back to the grid which I get paid for, similarly to your set-up.

Solar isn't that expensive to set-up in the UK the 5KWp + Battery installation was around £9K GBP (~$12K USD) But its paid for itself already because energy prices here are ridiculous in the region of £0.28/KWH

I may add another battery to it, its been on my mind for a while.

$12,000 USD is a good annual salary in Russia, excluding Moscow
In my village, electricity costs 5 cents, in the city 8 cents, and at those prices, no one is even thinking about installing a power generation system. Maybe only in remote areas without electricity.
But at $0.35 per kWh, I'd also consider solar power.

I had this problem when I built my first solar powered home for mining purposes, when the winter comes and cloudy is all there is I won't be able to mind through out the night, I ended up adding more panels to fill that gap, so even if it's cloudy all day I will still be able to mine and top up my battery backup, I think you should consider this too, also that battery of 3.5KWH is very small, for someone who wants to mine through the night you need more.

I went with good 12v Lifepo4 batteries with 314AH batteries



4 of this beast will hold up pretty well for this sun to come up the next morning, although I got this at their launch into the market which came at discount prices.
