and bitmaintech wants me to buy 2 for .58 each = 1.16 and shipping to usa is .39 btc = 1.55 btc for 2 units  377 x 1.55   = 584 delivered to my home in NJ usa.       no power no psu    

 for  195+ 195 + 198 =  588 I get 2 hosted units with 90 days power and psu's included

so 584 no power paid no psu or 588 both power and psu paid.  

   Lee has been pretty good but not perfect seller.  bitmaintech has been pretty good but not perfect seller/builder.

frankly if you want the gear in house use bitmaintech.   it costs more to do it but you have the gear in house.
if you want to save money use Lee and easy2mine.

I am no longer doing much mining anymore but this deal is pretty good.

 

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

these are quiet I had three.  three run with less noise then 1 s-3 by far.

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.

 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.

I agree I have tracked  a trend of 10% over 105 days.   which is not close to 5% once you compound it the difference between 10% and 5% is huge.

 I can guarantee  that if price jumps to 600 usd   the 10% will slip higher. 

It will be under 10% for sure unless coins go up.  I am convinced they  are holding back hash and hoping coins go up in price. 

 But frankly WTF do I know, not much when it comes to the top 5 builders of asics stock on hand.

  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 :

Network total   272813.567 Thash/s
Blocks/hour   6.53 / 551 s

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.

even 250 s-3's is only 125th at best.

and 125th earns about 2 blocks a month.

 back in the day i earned a coin a day oh i spent 5kwatts an hour in gpu's, but i got a coin a day for 5 kwatts.

 5kwatts now gets me 6.6th or about 2.8 coins a month


vs
    13gh in gpus and 33 coins a month

maybe this is a hosting farm in the state of Washington.  they pay 5 cents to a power company  and charge 10 cents to host.

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.

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

 that is why you are unrealistic.


he needs to make a little more each day for now and hope for a btc fiat price jump.


There is  much better chance for that to happen. then there  is to find 1850 free watts of power.

you can do nicehash or westhash   you are renting your hashrate out right now they are paying about

0.0155  per th on westhash and the same on nicehash.  no luck involved payout is consistent and based on what renters of the gear pay.


https://www.westhash.com/?p=allorders


https://www.nicehash.com/?p=allorders




normal luck you would get about

0.01438 per th

see  here

https://bitcoinwisdom.com/bitcoin/difficulty

bottomline is at 26 cents a kwatt you lose money.

mmpool.org

  will overpay with luck as in anytime a block is under 40% you would profit with your high power rates.

here is one of my s-3's  .

 I am getting .0151  a th from nicehash which is more then the .01438 norm for 1 th.
I backed up to westhash a lot lower then I backed up to a solo pool. 

If you get .0151 for 5 s-3's it is better then you are doing now.

what freq do you use? 600, 650, 700, 750 ,800 ,825, 838, 850

keep setting it  lower  if you are above 800.   also just run the 1 blade

if the blade set at 600 or  650 running alone has issues.  different software and a different pool.

if you can not get it to work well you may have a poor 1/2 blade

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.

    The bottom line is this Gaw charges 10 cents a kwatt to host.
 If your power cost at home is under 10 cents do not use them. In fact if you are in the USA and with the colder weather coming make it 11 or 12 cents a kwatt.

I did do a report and never got an answer.

I think these daisychain  the short tubes did. 

so tube + tube +tube + adapter + rasp pi

at crazyguy I have the rasp pi you sold me with the r-boxes.  If I buy one of these long tubes will you include a new sd card and an adapter to hook up the long tube to rasp pi?
