I would have thought up the same modular way, as this saves on the exterior, multiple small fans, and controllers and MB. Bitfury, and ASM have been doing it for awhile, they probably have custom Unit-sizes in house that the public does not know about, in their mines.

You make it sound like it will be a 7 foot 60kw tower :p
While the average person might have 100 amp service and could maybe spare half of that, some others may have 200 amp service, half of that is about 24kw at 100% load.

Because Spondoolies is preparing for next gen machines.

This would make sense as 208-240v is more efficient than 115v.

Maybe because it has been over the 236 ema the last 4 days.

Its funny how they usually lower the hashrate 18-24 hours before most diff jumps

A theoretical SP100 assuming .5 watts efficiency would require 5000 watts. Most people would have a problem to power it.
Would need 4 different 115v circuits, and enough power supplies, probably 9 x 600, with 18 power connector inputs on the machine.

When asics came out, people were using the cards to mine Scrypt and then convert ltc to btc. THe last great cards were the 7950 (2 years ago) and the recent r9 290 (1 year ago).

it is actually far more riskier to mine today with asics because you could always sell your gpus, but you cant do jack shit with asics once they go in red.
you cant really compete with asic producers. only if you have low electricity, like below 0.06 $.
Exactly. Intel q6600 is still only drop to $30 and 4 years ago was $60 XFX 5870 now is almost same price as almost 2 years ago on used market. Which one is more powerful? Or are they the same power/kind? 5870 was more powerful than 5850. It was clocked higher and had more stream processors. |

Yes becaus people who already had the video cards were using them to game, and mine on the side. But to buy it and mine exclusively had to be crazy. I dont even think they knew about the gpu power until 2011 or 2012. They were still using cpu back then until they figured out the computing efficiency

Radeon 5850 cards were about $300 usd when they came out in 2009. Very expensive back then late 2009. Lets say the price dropped somewhat by fall 2010, bitcoin price was only like .06 so buying a card for $150-200 to mine .05 a day used more electricity than the coins it mined. So it was still a gamble, experiment back then.

there is always a risk even with a legit bussiness, risk of the company to not delivers what have been promised due to some circumstances, even putting your pennies in the bank got some risk, we lives in a risky world, deal with it and get up
Yeah, you're right, but anyway, it's a difference to be blind or to see what you are risking. 1) If I would "promise" you to pay you 1.5 BTC in two years if you give me 1 BTC today, would you do it, without further information? * 2) Or would you prefer if I even lied to you? 3) Or would you prefer if I at least explain and show you and prove the existence and structure of my business? (If you choose option 1 I can give you my bitcoin address  !) (If you choose option 2, please wait for me to make up a nice lie. Maybe I charge some more for this, as it takes some brain capacity... ) #1 they are not selling btc, they are only selling hashrate, your mined btc may vary. LOL |

Someone is cranking up the hashrate. Bitfury or Knc

I totally agree on that its becoming a small group who will be left mining and it might hurt bitcoin that it evolves this way.
But again we can not say whats going to happen, but it sure looks like a few massive miner groups will be left.
I know some are huge chinese miners who have still access to cheap electricity.
But i think china will in time become much more expenssive because of the massive profits they made in the last decade.
I think that is one of the keys. The chinese are. not cutting edge but they can ramp up production quickly any new design and they can build at cost. I am imagining huge warehouses full of under volted chips at 1 generation back using company or government subsidised electricity. |

Could someone tell me what the current ROI for Genesis contracts are? Thanks
Between 300-500 days, depending of diff/price There are cheaper options available but Genesis has been providing stable and uninterrupted payouts in the past. This is how they make money. After you pay up front for the length of the contract. And when diff reaches a certain point where their costs are unprofitable (they add maintenance costs and a few cents on top of their costs for electricity) (maybe in 90-120) days they cancel the contract and its over. Whereas if you bought a physical machine (there is equipment capital resale value) you can always sell it to someone who has less electricity and maintenance costs/overhead. |

interesting-what is it? 21e6? Even more powerful. Bitfurys new Georgia mine. Also surprising is they estimate 40% of all bitcoins mined are using their chips. I guess their new venture into immersion technology will give them another leg up. |
