Hey guys, I need another 10 S1 Coupons. Will give the coupouns I get for buying them for free to community.

bitmain name: Didldak,


Thank you very much.

you are apply wrong mathematical techniques  for your calculations  as many people do not understand all the variables involved.

BTC roi has no meaning if you purchased the btc with fiat.  the fiat price has the meaning.

 ____________________________________________________________________________
Also   who cares if you do a btc roi  
 
 in this case.  I buy today  at .419btc  use a coupon pay .369 btc.

 I buy the btc from an exchange today  at 585 usd.

 My fiat cost was  .369 btc x 585 usd = 215.86 usd.

  I setup a dedicated account at btcguild.  all btc and nmc goes to it…….  

BTC crashes drops to 100 usd.  difficulty drops like a mother fucker.  
when all is done my machine mines 3 btc and costs me 1btc in power. net of 2btc

so I kicked ass in btc roi I turn .369 btc into 2 btc .

 I whaled   but wait my fiat  was  215.86 usd my fiat now is 200 usd
_____________________________________________________________________________
think this can't happen it can  ..

if btc price drops a lot big time minign will stop and diff will drop.

  So do not lock yourself into btc roi.  your calculations need to take a lot into account.

1)btc roi

2)fiat roi

3)heating bill reduced  if you use a space heater in the winter.  you can turn on an s-1 instead.  

4)So s-1's can be stored if they do not make any money in the months of August, Sept.  then in OCT turned back on.

5)Undervolt/underclock makes extra money

6)  rising btc price allows  for power to be paid off and sometimes the price rises way faster then difficulty.

7) using an s-1 in a space with 'free' power  Or in my case  I can use 800 watts and pay for only 200 watts.

  So an s-1 cost me  only 4 cents a kwatt.

I have 2 S2 coupons available for free, send a PM.

each ant should be ~$43/mo with 0.15 electric rate or ~$350/mo for eight of them.

This really depends on what kind of power supply you are using / what kind of efficiency you are getting at the wall; Bronze = 85% will mean 400 w = 460w draw at the wall and the best efficiency you can expect is 92% with a platinum rated psu. Generally speaking you can expect to pay $1.56 CAD a day / $48.21 a month for a single S1 at 0.15 cents per kw/h (I'm making the assuming you are OCing and getting near a power draw of 432w per device with a 92% efficiency). 

The lowest any one has achieved so far is 140gh/s with a 166w draw from the wall with a platinum rated power supply; that'd be $0.60 a day and $18.53 per month / S1. That'd be $148.20 for your 8 ants Klondike albeit with a loss of 480 gh/s (8x60gh/s).

each ant should be ~$43/mo with 0.15 electric rate or ~$350/mo for eight of them.

I have one S1 coupon and several S2 coupons for sale.

PM me if interested 

i live in ontario too... based on those figures if i run 8 ants with 650W PSU's am i to assume that my power bill will be $600 / mth?

your power cost is almost 3x what i pay in Ontario, Canada ($0.15/kwh CAD). thats the most significant reason your calculatiuons show no profit

I assumed 15% average in the future. If S1 does not pay at 15% it won't pay at 18%.

Last jump was 18%

BTC value has increased about 20% the last week, why did the price not drop by that percentage in btc?

I calculated over and over again, with kwh @ 0.27€ and diff increase 15%, the S1 will never ever make the btc back you invested if I have to pay monthly the electricity from mined btc.

What did I wrong? Why should someone buy S1, at least in germany it's just stupid?
