Heading back up. Must have been a glitch in the matrix...

5-6% increase now looks likely

We could be seeing some liquid cooled s23 units. they supposedly can run as low as 9.5 watts a th. so maybe some of them are coming on line.

Nice toy if you can afford to buy and run it.

BTC has now fallen BELOW $60K. Interesting to see if this lasts. Some marginal folks will have to decide how long they can "mine at a loss".

I am now at

270x.0304=8.208

$8.21 a miner earned and
$7.14 a miner burned

net 1.07 a day each  for 9 s21xps.

So they make $292.75 a month.

 they cost over 40k so 150 months for a profit at this pace.

to be fair they made way more year and late 2024.

so if I drop 14% in price to 52k I am a negative miner.

and if we go up in diff 6% this jump and 6% next jump and stay at 60k I would be break even.

I am not accounting for gear purchase price which is hard to figure.

Am I the only one who doesn't understand why this is so expensive?
The payback period is very long: at 5 cents per kilowatt, it will take 3+ years! In 3 years, this ASIC will turn into a pile of illiquid aluminum, Bitmain will release a 6 J/TH S25 Hyd, and network difficulty will skyrocket. I haven't taken the cooling system into account in my calculations yet.

[philipma1957]

yeah hard to justify buying this as compared to buying s21xps air cooled.

I get that if you switched to liquid cooling  you only need buy the gear

but it costs a Lot.

14,400 for 580 th burning 5510 watts s23 hydro.


7800 for 540th burning 7000 watts s21xp


so you save 6600 dollars getting the s21xp

not counting cool gear.

you lose 40th a day  that is $1.20
you spend 36kwatts extra at a nickel a kwatt that is 1.80 a day

so every day you run the liquid cooled vs the air cooled you make up 3 dollars.

but you laid out 6600 so 6600/3=2,200  days

2,200 days is over 6 years.

6x365=2,190

the price is too high.

I am about ready to go into a loss with my miners.

Maybe next jump

Sorry to hear that. It must be a real annoyance, but what can you do. We're all passengers on that journey.

Its been a fun exercise along the way and I've learned a lot but that's about all I can say for BTC mining.

I earned a bit back in the early days mining to Slush's pool before it became Braiins, but that's long been consumed by equipment failures and general upgrades.

I've spent more on mining kit than I've ever earned from it, all I can do is hope that I get lucky and hit a solo block.

I'll probably quit after the next halving. It just wont be worth the hassle of maintaining it unless BTC's value exceeds $350K

If this happens, are you thinking of shutting down the machines, or will you continue operating them as normal?

Good old days. I even mined there too.

Unfortunately, I never got around to buying an ASIC. But I wish I had tried.

I had a little cluster of Antminer U2's back then. I wish I'd paid more attention to it and kept it running. But with moving house and one thing and another it got boxed and forgotten about until I started getting interested in solo mining.

I agree its ridiculously overpriced. But then mining gear has always been overpriced deliberately so the hardware manufacturers stay just one step ahead of the curve. That way they always earn from it.

Every single high end mining kit out there is priced so that the cost of recovery is 2-3 years that's always been the case.

I've often thought the only people to properly earn out of BTC were the miner manufacturers.

We had a joke about how if an ASIC currently pays for itself in 15 months, according to the calculator, then we should assume it will pay for itself in 30 months.
An Antminer S23 Hydro Bitcoin Miner for 14,000 won't pay for itself in three years because the halving is in 22 months. So I don't understand who's buying this equipment.

there is a long complicated explanation as to what the big miners are doing.

Essentially it is this a guy like Elon Musk can print money via stock IPO's

Elon just created an ipo with 6-7.49 billion shares at 135 usd now at 150 usd.

that is 1 trillion dollars most of the shares are his so pretend it is 600 billion dollars.

poof out of thin air.

so buying 100,000 s23 hydros at 14,000 =

1,400,000,000 billion add cooling at 100million and he now has 1.5 billion in mining

and still has 598.5 billion from the IPO

what is 100,000 units going to mine well

0.55ph for 1
5.5ph for 10
55 ph for 100
550ph for 1000
5.5eh for 10,000
55eh for 100,000

fairly easy for him to do

add 55eh at the drop of the hat and push out old less efficient gear.

and still have 598.5 billion from the spcx IPO in his pocket.

take it further

110eh and the cost is 3 billion and he has 597 billion left from his ipo

or 220eh and the cost is 6 billion and he has 594 billion left from his ipo

and you can see this is not about making money by mining

this is about controlling the mining.

lets go more

1100eh costs him 30 billion of his 600 billion

and he owns half the network's miners and they are the most efficient ones at that.

and wait for it he still has 570 billion of his IPO from spcx.

So at this point you can see he can print money via an ipo and own half the network
for 30/600=0.05=  1/20 of his IPO money.
