We have have this guy on our 3-Phase 400amp panel:

It's a nice little budget modular system for our 125KVa setup.

If any of you are seeing that there is no profitability for the S9s, just sell them to me for $1K, haha.  I do not mean to insult, I am in it for the long run and see a GREAT future in Mining!

Manitoba would probably be best for the electric cost.  S9's would run you a profit I would bet.  IMO it would be best to wait until the next gen miner comes out but you would make bang with an S9.

Hi Louis,

Mining can be profitable anywhere, but Manitoba and Quebec are likely your best bets in Canada. Affordable electricity is paramount in this business.  How much of his setup costs go to actual mining machines depends heavily on site selection and whether the property is leased or purchased and whether the facility is purpose-built or converted from a previous use such as a factory or a server farm.

What a lot of people forget about industrial mining is that the land you purchase and improve is a tangible asset with a re-sale value and there's a huge market for 2nd hand miners.  The Russians have the cheapest power on earth and they buy up used miners by the thousands, sometimes the Chinese will, too. There are definitely opportunities down the line to recoup costs on the initial investment.

My partner and I are looking to open a mine in Manitoba in the next year, so maybe there's an opportunity for co-operation.

Spondoolies wasn't competative with Bitmain because they build their miners to be configurable, NOT because their chips were too expensive or not comparable.

 If they had been SMART, they would have settled for fewer sales and NOT tried to compete on price - the same route Caanan is taking with the Avalon - except that the SP20 when set for the same hashrate as the S5 was almost identical efficiency level and ran a hair cooler.

 The SP20 compared to the S5 was a night and day difference in many respects - the SP20 could get down semi-close to the high end of S7 efficiency range (at a cost in hashrate), or it could be tuned to do 50% or so more hashrate than the S5 (at a cost in efficiency), and that tuning also allowed it to handle high temps a LOT better than the S5 could.
 You could also STACK SP20s, they were a lot more compact design in actual usage (longer, but lower in height and no cables/lack of a top made the EFFECTIVE height quite a bit lower, and almost identical width).
 The SP20 was also overall a much more PROFESSIONAL design - it's STILL a more professional design than the S7 or S9 or even the Avalon 741.

 Configurability and professional design came at a cost though.

I don't like the relatively low reliability of the S9, and nothing BitFury based showed up for a long time, so I've BEEN waiting.

 If the S9 was RELIABLE, I'd probably have been accumulating them for a while now.

Same after some teaser videos the chip news from bitfury has dried up most of there videos now are to promote their data centers .

Unlike most people on this list, I am in the chip biz.  I cannot say much.  I can say this:  A US$300M investment in a 7nm-based chip design will get you pretty much that.  Then you'll need more money to get your chips fabbed and you systems built and installed and everything else.  A few $millions will go a long way towards physical plant for installation, but it takes a lot of money to play in the 7nm game. 

There were some comments in this thread about the move from 22/20nm to 16nm.  The 20nm node was largely skipped by the industry because 16nm node added so much value with the introduction of finFETs, that it wasn't worth it to continue investing in 20nm.  The 16nm node still has a ways to go, and has had a number of rounds of refinements.  I don't know which actual 16nm process is being used by BMT, but they could probably get some mileage just by re-spinning into a newer 16nm process.  If they cared about improving the product.  However they're in a situation where they can sell all they can make, and price is hardly an object right now, so why waste the engineering resources? 

7nm is a huge wall to climb for anyone, and I don't think anyone's going to be building a 7nm miner for at least another year, maybe 2. 

If someone does come along and proves me wrong, I'll buy it.

Good afternoon. What technologies are needed in the work? Please describe the project? Where can I send a CV?
