Topic: My new diff thread covers Oct 10 to Oct 22? 1.85% to 5.07% ? (Read 2532 times)

still sorting these

good luck.  and here is hoping to lots of flat diff jumps.

I just got a S3+ off eBay for £200.  It's basically unused.  I'm running it to replace a clutter of older Avalon-based ASIC boards that drank 1kW for about 180GH. 

The S3+ is doing a shade under 500GH with 360W at the wall.  I'm very happy to let the S3+ sit and churn away until it pops, especially when difficulty is sitting still.  I'm in Bitcoin for the long game - I like many have wasted hundreds of BTC buying pointless ASICs, and the only ones that turned a high profit were the Mk1 ASICMiner Blades.  Now I'm just happy to sit and churn away and hope BTC is worth a lot more in 5-10 years time.

Whether you've paid it off doesn't matter, whether you've bought it is what matters. Sunk cost fallacy.

Latest numbers look good for under 2%

  (+0.9599%) diff  jump


pretty flat for this jump.  will stay flat as long as btc stays low.  reasons are simple most hashing is done by the builders and margins are too tight for them to build out.

yeah there might be profit as low as 300.  but if you are running a 30ph setup and it has paid itself off.  

 the 30ph gets 431 coins a day.  if your power is 5 cents and you use .6 watts a gh   you spend 18mw a day that is  900 a day in power .  431 coins are 163000 a day

so after power your profit is 162000.  take salaries  a few other expenses and that plant earns 150k a day.   you don't need to expand.  if you keep coins flat and diff flat you just make big money day after day.

the interesting thing here is home miners can survive in this model.

   they need .8 watts  a gh and 12 cent power with 3% growth  and 380 usd coins ..  those numbers you do roi.

and if you could pull off 2% diff jumps you make pretty good money.

 

Yeah I can see that idea is possible but I prefer the conspiracy one better.  It is a speculation thread after all.

Very likely yes, since the miners cost less to manufacture than they are sold at, thus they will always be profitable for the companies.

Funny how english works.



 As for s-3's running them  now reminds me when I ran sapphire 7970's and coins were 6 to 10 bucks a piece.  I earned 1 to 1.5 coins a day and monthly profit was very small.

I would agree the S3 is a good bang for its buck.  You set it up once and basically let it run.

Also they have the S3 Plus to get a little more hash then first batches.   It is hard to beat the price on them if you already have PSU's.  If not make sure to add price of PSU in roi math.

I would have said the opposite. It was too much, too soon.

But myeah... same thing.

 if you can get used s-3's on the cheap  they may be worth buying if you have power under 10 cents a kwatt.

there are some s-3's here and there for under 250 usd.

I got a few from this seller.

Could actually be a good gamble to expand hobby mine capacity, assuming bull runs and spikes halt for the next 30-60 days.   

  Sometimes I believe that. Sometimes I believe they have 300ph they are holding offline so as not to shock the network with back to back 40% diff jumps.
 Pure conjecture on my part.

 But the long tubes from Asicminer are easy to build and they could be cooled in a tank of oil pretty cheaply.

today's diff numbers are :

Bitfury, AM, KNC and Bitmain would add the hash power now if they had it ready. They're profitable now with the current price of bitcoin. So it wouldn't make sense for them to wait for higher bitcoin prices just to power up new datacenters.

They just don't have the gear ready now or they're already adding hash in smaller increments and it's difficult to notice just yet.

If it does happen coins will need to drop to under 100 usd.  And the problem is as soon as coins go up the diff will go up.

I have 6 s-3's  . I can turn them off and on with ease. They are bought and paid for 3x over.

Many larger people then me can do this.  I suspect bitfury, asicminer, knc, and bitmaintech can add 300ph to this network in under 2 weeks if btc price was rising.

Hey I run my s-3's at freq 206.25.

The power is lower.
The hash is lower
They run very quiet. 
They are under 40db.
They are cooler.
I pull 1038 watts.
I get 1200Gh.
I have not done any resistor mods but I will.

  At current diff and current btc fiat they earn more then power costs. So they run.
I can afford to shut them down if they don't earn more then the power.

50%? Never going to happen.

Exactly, we need 50% difficulty decrease in the next two months.

You could potentially use existing bitcoin to buy more miners hoping that the price of bitcoin will remain low for the medium future (but a long term outlook of the price being very high) with the intention of holding onto the bitcoin the machines mine for the long term. This could result in the miner being able to essentially buy bitcoin at a discount

yeah I think no matter what happens home mining will never thrive again.

  If btc shoots up to 800 usd the diff will just catch up very quickly.
 If btc shoots up to 1600 usd the diff will just catch up very quickly.
rinse repeat.

Too little, too late. 

yeah if you look deep into the 3 periods of asics .

  we are dropping the diff increases.

 the last 104 days are under 10% avg

Well, sorta good news.

Looks like it's as bad as ever, but not getting worse as fast for us...

As usual I do bitcoincharts and bitcoinwisdom one runs low one runs high.  so 1.85 to 5.07   is the guess for now.
I also added a section on diff since May of 2013 when asics started to be available via asic miner

Difficulty History of asics and btc

I divide the  diff jumps  into 3 sections.  I realize that cut off is arbitrary some will say I should go back to the first Avalon's of Jan  2013 for Early asic not May of 2013  but in May of 2013  asic miner was doing good sales of the little .333gh block erupters so I used May of 2013 as a starting point.

With the maturity of asics growth has finally become slower.


Asic maturity days  So far we are  about 104 days into the mature 28mn chips.  So far  this is about a 9.77% avg for this time period.  I see it going lower then 9.77 % due to power cost and of course  price in fiat.
