Any USA based people here have miners hosted in Canada? Just curious if anyone here has done this and if you ran into any issues.

Ordering the s17 for dec may be smart to do if trump taxes are ended it becomes a very good deal to buy one.
I'm not seeing Trump taxes going away before the election. China is trying to run out the clock. In my opinion, more chance of tariffs going up by December. |

It would be nice if they gave us a formula for how they'd calculate the price. At least what circumstances would lead to a lower price. If a competitor releases a 45W/TH miner at a lower price for Dec. delivery, will the match it?

For continuous loads, you should not exceed 80% of the circuit rating. If your s9s are pulling 1200W in low power mode, and the S17 is pulling 2385W in normal, that is 5985W, or 5985/240 = 24.9 Amps, which is over 80%. In reality, it will probably end up being higher than that, so not a good idea in my opinion.
Best to consult an electrician.

Yes, you can expect the S9 to go by the way of the L3+.That is by design. I also hope the OP is aware that his KWH Rate is NOT the important part of his calculations. When i see him post that he pays ".039" I immediately wonder if he is looking at just his rate per kwh. There are a lot of other charges that come into play. ( Fuel, Delivery, taxes etc etc.) If he is not at least a decent sized commercial miner I highly doubt his "all in rate" is .039 per kwh.
That is a common mistake, but there are a lot of local areas where power is that cheap and doesn't require megawatt usage levels. If only I was lucky enough to have come from Platsburgh, NY where even the residential rate is 4.36¢ ... https://www.electricitylocal.com/states/new-york/plattsburgh/or Medina,OH where the industrial rate is 2.18¢! https://www.electricitylocal.com/states/ohio/medina/I haven't found a residential rate that low, but it is possible that the OP owns a manufacturing business that already has access to industrial level pricing. As far as the S9 profitability, assuming that you actually do pay 3.95¢, I think there is a chance that it will still be profitable after the halving. As Phil has pointed out in other threads, there will likely be some downward pressure on the difficulty as S9s start to become unprofitable and get shut down (not that difficulty will go down, but will possible stall or increase slower). If BTC price increases, and ASIC manufactures don't flood the market with more efficient gear, and a lot of the S9s out there are burning power at >3.95¢, then maybe.... A lot of "ifs" in there though.. lol. |

Should probably ask the seller to pay the escrow fee. That way they'll be out something if they don't deliver.

So, no answers to any of PopoJeff's questions? At least give us a good story about why your are selling for $1000 under market value....

The crypto tax situation here in the US is ridiculous... my goal is to get my 2018 (and 2017) taxes filed before the Oct. deadline....
I paid for one of the online crypto tax services and it makes everything a lot easier, worth every penny.

Rather than Turbo Mode, I'm more concerned about when we should be making the switch to Low Power Mode.
For soon to be diff of 11.9T, and price of $10250, break even between normal mode and low power mode is $0.1851/kWh power cost. That's 50TH @ 1975W vs 36TH @ 1296W. So higher than $0.1851/kWh use low power mode, lower than $0.1851 use high power mode. |

With presumable close to zero electricity cost from the solar, wouldn't the lowest cost per th/s be the best idea?
S9 could be had on the cheap these days...
You need to ROI on your solar array as well as your miners, so not really. Even at 1$ per watt for an array (which is unrealistically low even for huge scale), you'd need to spend around 10K to power each s9. With diff rising, it may take longer than the 25 year life of the solar panels to ROI with s9s. |

@philipma1957
Do you think the T17 38Th/s for 1145USD is a good price?
It is a good price for some people, but not for others. Depends on what you pay for power, how much risk you can tolerate, what you think price and difficulty are going to do in the next year, ..... etc. |

I've been lazy, so the 1070 has not made it to ebay yet. Sill Available.

Yup, wire size must be larger than what the breaker can handle, but honestly I think the breaker was bad, i don't understand how these breaker function, but common sense states that if the wire got way to hot to the extent that it melted, the breaker should have sensed that and did the exact thing it was made for "kill the power" but the response took way too long till the breaker went on fire.
Yeah, but over time the overloaded wire can degrade and fail slowly, so the resistance at a failure point can keep increasing. With the same current draw and increasing resistance, the wire gets hotter and hotter. Eventually it can essentially turn into a heating element, and that could have cooked your breaker. |
|

I think the lesson to be learned here is just make sure the correct size breaker is installed. The same meltdown could have occurred if a power supply failed in the right way. The cost of a 50A breaker isn't much compared to the damage that could have occurred.

I'm sure there are a lot of miners that would rather use the smaller pool if the pool hashrate was high enough to average a block a week.
What would be great is if there was a site that would allow users to set multiple pools with priority and pool hashrate threshold, or average time to find a block threshold. This would allow you mine at the larger pool, but commit hashrate to a smaller pool if the pool hashrate goes above your threshold. The combined hashrate of all users that committed hashrate below your threshold to the same pool is used to determine if your threshold is satisfied.

You could move some % of the hashrate to the smaller pool, then calculate the 50% going to the host from the hashrate still going to viabtc. Nothing changes for the host, but you get some more freedom to use the pools of your choice.
So if you moved 25% to kano leaving 75% on viabtc, host would get 66.7% of the rewards from viabtc.

If voltage drops too low 10% of the time and you shut down all those miners that drop out (144th?) every time voltage dips , even with free power that is only about $3.50 lost per day, or about 18 months to pay back the $1900 for the regulator (if price tracks diff). Even with the all s17 scenario, with power cost you're probably still taking a year.
On the other hand, the regulator isn't going devalue like a miner over time. When the s17s are no longer profitable, the regulator might still be needed for the the s17s replacement. So thinking about it that way, a year or two to pay back the investment isn't really that bad.

At the moment my power/hosting bills are low enough that I don't need regular payouts. Right now I'm actually not selling any BTC to cover my bills, but I'm ramping up to the point where I'll need to by the end of the year. My plan is to keep on Kano as long as they remain high enough to average around a block a month. I'll still be able to float 3 months without an issue, but if it gets much longer I'll move whatever % is needed to cover the bills to a larger pool.
If everyone just put the minimum % required into the pps pools to cover the bills, then this wouldn't be an issue.

I'm impressed with the efficiency of the TSI regulators, they claim 96% - 98%. http://www.nooutage.com/pdf/TSi-VRp-7500W-15000W-1ph_2012.pdfCouldn't find specs on the Amazon one, doubt it is that good though. You could buy a single phase monitor and wire it to control contactors for all your equipment that has issue with low voltage, and spend the $1800 left over on some more hashrate. |

If it is infrequent, this could be a lower cost option to use while you scream at your utility to fix the issue. It'll shut down power if the voltage drops too low, and can be set up to restart after a delay once voltage comes back up. Not ideal, but it'd take a long time to pay back several thousand dollars for those voltage regulators. https://www.amazon.com/ICM-Controls-ICM400-Three-Phase-Protection/dp/B000TMM746 |
