Topic: New Mining Farm. $100k to invest. Advice needed. (Read 2852 times)

This is little bit fine about the how solar mining works and can earn bitcoins. Please let me know that mining fees seems increased more than last month as I noticed, To say frankly simply it doubled the cost for each transaction. Please let me know Hash rate to use and want to use the antminer s9. Will it be preferable? How much it will take to invest and returns?

I'm planning to do same...and thinking to start with initial

10 items of -s9
10           -avalon
10-             Lt3 or D3

and few GPU rigs for ETH
as I'm understand every farm is different,even power stability is important, ambient temperature, humidity at ctr

so after 2-3 month of ranning,I can say ,which machine is most suitable for me:)

This is a simplified scheme, I think if this device worked -
it would have been done for a long time and appeared on the market

This looks like a device that harnesses radio wave energy, much like your radio or wifi router, but I doubt it could generate a lot of power.
For this to be able to power a mining rig that shiny metal plate would have to be the size of a house

 Douglas is mostly fairly empty - I think the whole country population is under 50,000, so there IS an issue with finding space outside of East Wenatchee (and space THERE is kinda pricey even when you CAN find it).
 Chelan and Grant have bigger cities, but still not really big - pretty sure both of those counties are under 100,000 total pop - Grant rentals tend to be pretty cheap, Chelan tends to be pricey worse then Douglas unless you can find something that is NOT in Wenatchee or very close, then it's only semi-pricey.

 Unless you're going BIG, you don't really need "industrial" space - for a small miner, "shop" or "warehouse" type space can work fine - but if you're going "big" you can probably afford to build out from scratch and likely SHOULD do so (reference GigaWatt).

 I've never been sure if MegaBigPower and ZoomHash had their facilities in Chelan or in Douglas (MBG might be a mix of both).
 Toomin and Columbia Basin are both in Grant (both are big enough to qualify for "big business" or "industrial" rates).
 I forget who else among the "bigger" fish are in the area and still in operation for mining.

 Microsoft, Yahoo, Dell are all in Quincy in Grant country (there's at least one other "GIANT" server farm there but I'm don't remember offhand who owns it, plus some smaller ones owned by Intuit and Sabey).
 

How possible free electricity?
I think is not really.. I find about Tesla but anybody realize it?



Circuit is easy, but how it works?

Well you're right, just looked up local electricity rates in douglas, wow. I tried looking up industrial space however, I'm assuming they're mostly occupied by miners. A few houses here and there available for rent which I suppose you could operate out of if you're getting those kinds of electricity rates, but other than that there isn't much out there in the middle of nowhere.

 Don't look at statewide averages - this has been pointed out before A FEW TIMES in various threads.
 Any site that ONLY lists a "by state" rate is listing an AVERAGE - I don't know of ANY state in the US (possible exception for Rhode Island as it's so small) that is only covered by one power company/PUD.
 Washington State in particular is covered by AT LEAST 20 different power companies/PUDs.
 I know of quite a few COUNTIES that have more than one power company/PUD that SPLIT the country between them (Iowa is notorious this way).

 As has been SPECIFICALLY mentioned in a few threads, there are 3 counties in Washington State that can get you under 3 cents/kwh all-up cost - Chelan and Douglas for EVERYONE (Residential rates ALL UP are 3c/kwh or a hair less, as are "general service" AKA small business rates) and Grant if you use over 200 KW on average (mid-sized business rate) or higher.
 All 3 have "big" rates that are even less all-up, though none of them get down UNDER 2c/kwh (as I recall Grant gets the closest on it's "industrial" rate but it's still more like 2.5 or a bit more).
 As it happens, each of these counties is covered entirely by a single county-wide PUD - and all 3 of them OWN 1 or 2 major dams on the Columbia River (2 each for Chelan and Grant, 1 for Douglas, IIRC).

 For reference - the Grand Coulee dam (largest capacity dam in the US and as I recall it's still #1 for all of North America) straddles Grant and Okanogan counties (the Columbia is the border between the two counties in that area), but that damn is Federal owned (Bonneville Power Authority) and none of it's power output is sold to Grant County (not sure on Okanogan).

 The "average" for Washington state is a lot higher, though it's still one of the lowest STATEWIDE averages in the US it gets pulled up quite a bit by the Seattle/Tacoma area.


 Nuclear power in the US is NOT particularly cheap - way too much regulatory BS just getting the PERMITS to get plants built (and as I recall there hasn't been a nuclear plant COMPLETED in 2-3 decades), drives their amortized cost up a TON - and the INSURANCE for them is also very expen$ive (I think the only insurance carrier is the Federal Government, but not 100% sure there).

or you could study the TESLA patents and have FREE electricity
Or build your own version of Walter Russell's Optical Dynamo..
or John Hutchisons coils or Stubblefields coils

Free electricity is easy...NOT GETTING SHOT FOR DOING IT..... is the hard part

Just be sure to destroy them before the Chinese army seizes your factory bank account and hard drives and deports you back to Canada

I would actually love to know where exactly, because even if you look it up the cheapest electricity rates in the USA are in Washington but they are nowhere near 2-3c/kWh.

2-3c/kWh must be the rates that huge mining operations get, but I can't imagine anything under a $100,000 mining operation ever getting rates like that, even if you do live in Washington, no?

You can mine profitably at 8.9c/kWh, that is around what most profit estimations are based off of. Those mining with a 2-3c/kWh rate are those making BIG bucks.

People who usually live near a source of cheap power - either a hydro electric dam or a nuclear power plant. Lots of places have really cheap power, it is just that in the inner city or in more densely populated areas the power tends to cost more.

Where is everyone getting 2-3c/kwh? In my area, power runs at 8.9c

Thank you captain hindsight for your valuable input.

Idiot...if you had just bought BTC  when you posted you would already have more than doubled your investment.

Since ALL of the large supercomputers are massively parallel machines (some massively GPU parallel), they might actually manage to beat a S9 at Bitcoin mining.

 Tradeoff - the ELECTRIC usage of the things is commonly measured in MEGAwatts.....

Great insight. It used to be such that new miners came out every year and it was a waste to keep your miner 3 years, but it certainly is not the case today at all.

On a complete sidenote... I wonder what would happen if the world's largest supercomputer started mining Bitcoin. How many would it make each day? MY bet is less than a laptop did back in 2009. lol

Well I'll be damned... 2 intelligent 'I want to invest xxx$ to start a farm' threads! The other is Avg yield from Avg Pool Spank me red and call me Suzy...

heh heh, ja. Almost like typical ROI on manufacturing capital equipment purchases. Welcome to the more mainstream real business world folks.

As Quint said, thankfully the node wars will be stable for quite some time so the current 14/16nm miners will have a nice long run of another 1-2 years before the next Sparkly Thing that is also worthwhile comes out..

BTC hasn't averaged 10% jumps for a while - gets 1 or 2 in a row when Bitmain ships out a batch of S9 units then flattens out for a while.

 Also, once profitability for folks in the 3c/kwh electric range drops far enough, SALES of new miners will start dropping and diff increases on average will drop quite a bit.


 We're in the middle of a transition phase right now, the current generation miners like the S9 are the FIRST that were built on a "current" process node ever, and folks are still getting used to the fact that "new generation of miners every 6-9 months" isn't going to HAPPEN any more - and ROI timeframes are also likely to extend out a lot more than the old-time "better ROI in 6 months or less or the new stuff is going to kill your profitability" norm.

 The big price surge on almost all cryptocoins this spring confused things a lot, but the NORM in the future is going to be an expectation of 1-3 YEARS to achieve ROI for most coins most of the time.

 Unfortunately, most folks haven't wrapped their mind around that yet, they're too used to the OLD model where you never HAD 1-3 years to achieve ROI because the generations were so short.

What work is needed after initial set up? I thought after initial setup miners doesn't require a lot of attention if they are reliable?

I'm mainly concerned about increasing difficulty more than 10% every month and reliability.
If Avalons are reliable than it's only difficulty.
I think with $0.02 electricity cost it is still no brainer to invest in mining?
