if you pursuit honest and fair mining, why not use https://kano.is? No funny business behind as it is as open and transparent as it can be and even able to know how much the pool earn from you.

this quantity and floor space, you do not need to worry about building any wall or segregation. Until summer, you have plenty of time to experiment to build a small mining room. HomeDepot or Costco metal shelving be plenty with some 2x4 with drywall can do the job. Please buy a good commercial grade internet router and network switch and some camera and a laptop to leave in the warehouse to easy remote in to check on your equipment. Happy Mining ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) simple shelving will do the job for you https://imgur.com/a/LRQNvgbI won't be building out the entire space.... It's approx 6,500 sq ft and right now I've got 3 ASIC up and running at my house and 4 sitting waiting to be utilized.

blackout must be passing by to some sad mining data centers ![Cry](https://bitcointalk.org/Smileys/default/cry.gif) And here we go, for a small timeframe we went into negative pace
Agreed, some equipment will never see the electricity again or for a long time but if BTC price rises more such as exceed $70,000, another frenzy to come. now headed to the winter in many countries, miners that are being used in leu of heater will return that are paid for by the welfare checks. It is a known phenomena every winter.

for easy setup in USA be make as many 30amp breakers you need for the miners. air flow wise, many solutions and there is no 1 correct way, however, you be better off isolate hot and cold area. Please be careful as mining unattended can cause the facility to burn down to the ground unexpectedly. Please install many monitoring devices or sensors to alert you of any potential problems coming at you ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Current generation hardware is about in the range of 3000-3500 watts at 220v. It will function at 208 - 240vac safely. I think the factory recommendation is at 220vac. If you turn on 600amp worth, it will cause significant heat as well as the noise. Please make sure your neighbor be okay with the high pitch noise for 24 hours a day. Happy Mining ![Grin](https://bitcointalk.org/Smileys/default/grin.gif)

amount of hardware they are selling in attempt to recover investments from china market customers who were expected to receive miners in last year's purchase contract that are due for delivery now may be a BIG CHUNK. I speculate manufacturers have more miners than themselves and customers can power on at the moment. HOWEVER, they are not willing to sell at lower price For a mere 12k USD. ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) I don't think there will be any discount sale for miners. One thing they could try to do, is actually have them available for sale during Black friday / Black week.

not cheap but check with Aliance and AIG. ask to underwrite specific version to fit your model but you may need 20 Mega Watt or larger facility for them to be interested to service bespoken package with higher risk. facility will require UL based infrastructure to be even considered ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) Hey folk.... long time lurker, first time poster.
Are there any community recommendations for insurance providers covering hosting facilities? I'm not aware of many places offering more than physical loss protection, and am struggling to find agents who deal in this space registered in Arkansas and Texas.
Thanks!

no but it is on sale at bitmain.com for shipping out in 5 days. Better to buy from the factory direct! ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) I realize that the likelihood of discounts at the moment on Bitcoin mining hardware is probably fairly low but I'd thought I'd ask anyway. Does anyone know of any sales on Bitcoin mining hardware with black friday sales on the way? Thanks.

KANO RULEs! ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) Alas the millions of S9 produced didn't magically disappear, even if you like to think they did. They're almost certainly over 1/4 the world hash rate.
LOL, you sure are clueless, you probably don't own any mining gears and you are still stuck in the 2016-2017 era. You need to wake up and smell the coffee, most certainly the standard S9s don't make anywhere close to 1/4, it is so funny i don't even want to discuss it. Says the guy who has a tiny farm and that's about it ... BM have the S9 code open source, if you can't find it
Your comprehensing skills are lagging worse than your pool, I said the only S9 source code available is the S9 as is, there is no source code available for the S9k and S9se. My pool has less lag than probably any other pool on the planet ... The '+' on the end is the same code with changes and additions.
This is another baseless claim, how do you know how different or similar the + version is without being able to look into the code of both versions, of course you don't and you are just saying stuff you have no clue about. The same way any coder would know how to do that. Quite simple actually, you look at the binary. Hmm, I wonder who has no clue ... do you know anything at all about coding? As you imply, I clearly don't, I certainly have no proof of all the well known free coding I've done in Bitcoin ... ... ... 2nd main developer of cgminer, earliest firmware updates by anyone (S1, S2, S3) including adding and fixing BM's code into cgminer, pool software, full coded from scratch hi performance database, bitcoin performance, more miner driver code in cgminer than anyone but ck, dealt directly with Bitmain, Cannan, BFL, BlackArrow, MyRig, BitmainTech, hmm I guess that could be most of it ... probably think of others if I wasted more time on this ... Yeah you're right, what would I know about anything, nothing at all. You're back on ignore, no idea why I switched that off ...

if really does not work for Poolin.com any more, why not return this account to POOLIN guys so they can continue to monitor? or you "do not work" for poolin because poolin now operates via complex web of shell companies? so I work for poolin but I do not work for poolin trick? or you means you no longer share the bed with inno where these chips came from? Hi NeutralLTC Where's the source code for this: Interesting I'll have to ask in the poolin thread why there is no source code for that ... i don't work for poolin any longer. i suppose someone else from the team can monitor this thread.

mining container use different electrical rules when constructed. Best to seek container manufacturer in your own country or in the same region with the same rule. You want to avoid a bad news from customs or local utility company that you can not import it or not able to use the container due to different electrical safety requirements.
Did you think about DIY?

So buy $3Million worth of miners with a ~10 month ROI, only to have your host boot you after your 12-month contract.... that could hurt.
Would be interesting if someplace would host a mini-container, something with a max of 200kw or so.
SETUP YOUR OWN be more expensive but can avoid 1 year BOOT. OR co-exist with your host with higher fees so the host be profitable to keep you. Being a small player has something to do with it, BUT being seen as unprofitable customer (none sustainable business) may be more likely. If it is a profitable or sustainable cost paying customer, host will probably love you with even 1 unit hosting. Invest proper cost into your host. Be reasonable with the host for uptime and maintenance performance. Many host seem to be rejecting S17 and T17 who are paying lower hosting fee while these miners required high maintenance and support requests and frequent monthly bill adjustment due to some offline times and maintenance time needed. If host knows you are PAIN IN THE BUTT customer with essentially no gain or possibly the net loss, those customers be the first to go if someone else offer more profitable propositions. Coindesk.com article said it cost publicly traded company to build the mining data center is about $1,000,000 to $1,500,000 per Mega Watt in Texas. If use the newest S19 as example, it is about 3000W each. Usable 1Mega Watt can service about 330 units of S19. If use 80% load math, about 270 units per $1,000,000 to $1,500,000. This means if hosting customer does not bring $3,030 to $5,555 profit margin, Those newly built data centers probably has 0 interest to offer hosting to us if we have zero intention to pay off that cost in the next few years with long term contract or start with higher hosting fee. I am sure, there are much cheaper data center host all over the place with less than perfect performance and conditions but it will work with 80% uptime which be acceptable for mining performance. Cost for those data center may be 50% 75% cheaper but the stability may be the trade off. Special mining container for sale seems to go in the range of $100,000 to $250,000 with about 300-400 units of S19 capacity. This cost seem not include the electrical infrastructure outside, Electrical transformer to service this may cost $50,000 to $100,000 to include the electrician and material and permit expenses. This means if any lucky hosting company out there that gets free transformer (If small family owned hosting shop may be BUT as industrial size operation, NOT REALISTIC) Current Covid crisis, the salary seem to be not cheap now days. Owner wants his pay, company needs administrative staffs as well as customer support and technical staffs. That is additional expense on top of the base electricity cost the hosting company has to pay with rent or mortgage of the business location. I speculate, many small size hosting facility who built 5-10 Megawatt size facilities did not have realistic business projection with real operational cost. They are now slowly realizing what the real cost would be as push to expand their facility further. Now days hyper inflation with everything to include the building material cost is getting so expensive, too. best option be to search for land or building that has enough electricity you need to setup your own container, or find host who will agree longer term service contract with higher monthly fee to be win-win condition. quick search shows many host offering immediate hosting option from $0.08/kwh but has minimum sign up quantity restriction of 10 units or more. With current bitcoin price and data center demand, $0.1/kwh even seem reasonable, compare to residential or commercial electricity price and warehouse rent to pay if plan to operate less than 1 Mega Watt. Best $5,000 - $10,000 rent with 1000 amp old ice-cream parlor or old rural agricultural site to find near you. Best solution be set up your mining on your own land it seems or find a host who offers long term stability but to expect higher signup cost or higher monthly fee to avoid early termination or none renewal pain. If you sign up $0.07/kwh hosting now, higher probability of BOOT at the end of the initial contract term or earliest contract termination date. Miner wants ability to cancel hosting contract as short term as possible = you take risk of BOOT when market heats up. what puzzle me is a guy who spend $100,000 to buy miners from someone on telegram chatroom instead from the store with the brick building. You expect the miner to be usable for 3-4 years or possibly more but only sign up for cheaper short term cancelable contract. When you rent a store space or your office space, you sign up for 3-10 years lease with the landlord. Why NOT with your expensive mining business enterprise does not do the same? Cheaper shorter term contract is similar to 1-year ARM home mortgage loan that you know you have to refinance shortly after the 1-Year ARM term ends or your monthly payment is so painful until you refinance. Quick google search shows many hosting options but many seem to be reselling larger hosting companies' space with markup, too. I see $0.089/kwh with 10 units minimum. This means, when the distributor price becomes none profitable or distributor demand unreasonable service from the big host, the distributors to be experience the BOOT. Always GO direct with the HOST to lower the risk be 2cents ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Many delays are from cost savings. Many difficulties setting up the data center comes from attempt to save cost via engineering, also. Hence, more delay. Big questions to who are facing possible BOOT. Refused or Decline to pay extra $25-50 usd monthly hosting fee when you are earning $500-$800 usd per month worth it?

work perfectly and hiccupless in mineral oil tank ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) s17+ and t17+
HAHAHAAHAHAHAHAHAHAHAHAHAAH!!!!!! Oh man.... haven't had that good of a laugh in a while.

both not looking a good option ![Cry](https://bitcointalk.org/Smileys/default/cry.gif) one day, may be walk into a store and buy it and walk home with the miner ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) thank you for sharing the Lesson Learned. Buy INSTOCK item ONLY if possible, direct from the manufacture. Bitmain seem to sell S19 from stock with shipping in 5 days now
Agree with all but the "Direct from manufacture[r]". For Bitmain gear, that often comes with long lead times, and for us USA folks, a 27% tax. Also... unsure what the differences are between the S19Pro 110TH I bought back on September 5th for delivery today at $15,400 plus shipping and the S19J 104TH machines Bitmain is telling today at $12064 - my cost $15,393 plus shipping. One also needs to factor in the potential for a long shipping time due to oversea shipping backlogs in the current environment.

Bitcoin is not anonymous. It is fully viewable public ledger. Anonymous money is a fallacy. If you want privacy, may be to use privacy coin or fiat? Carrying the PSBT file throught a border and then getting the laptop checked in customs for instance. Then don't carry it through customs. As achow has said, it is going to be publicly viewable to the entire world once you broadcast it, so you can store it on the cloud, email it to someone else or yourself, post it on a blog, any method of digital storage which you can access later once you arrive at your destination. If you do all this with a brand new and otherwise anonymous cloud/email/whatever account, then there is minimal additional risk to your privacy. I've heard stories of people getting their laptops confiscated if they had full disk encryption and refuse to deliver a password. If border agents are interested enough in you to force you to decrypt your entire disk, then they are going to be interested enough in individual encrypted files or containers to force you to decrypt them too. If you really want to hide something from border agents, then don't take it across the border with you. If you must, then a hidden volume with some "decoy" encrypted data is probably the way to do it, which is far outside the scope of Bitcoin Core. I can't agree with this logic of "the entire world will know". The entire world will know X transaction happened but not that it's tied to you. The problem is linking this data to you. It's the basic pseudonymous principle of making transactions in Bitcoin. So if for instance you save a .psbt file in an usb pendrive and you forget to delete it, and someone gets access to the USB physically and manages to tie this USB pendrive to you, then they would know you are an owner of bitcoins. So you have now become a target. But assuming this will remain as it is then you'll just have to guarantee that the file is put inside a Veracrypt container or something before it leaves your airgapped laptop. As far as cloud storage. All of these "anonymous email" services aren't really anonymous. And "anonymous cloud services" require that you dox yourself via paying a subscription usually. You would to find one that accepts BTC and mix the coins and hope it all goes well. There's also the problem that you never know what happens with this data if you don't control the servers physically. I haven't found any reasonable way to store stuff in the cloud and call it "safe". Carrying the PSBT file throught a border and then getting the laptop checked in customs for instance.
Wallet software is way more obvious than a PSBT. And wallet software will contain far more private information than a PSBT. PSBTs are just base64 strings, you wouldn't know that it is Bitcoin related unless you are looking for it specifically. And again, you can just encrypt the PSBT with a third party tool. Then it will look like an encrypted file, instead of specifically an encrypted PSBT as adding an encryption standard would make. I have always wondered why the wallet.dat is not fully encrypted, but in any case you wouldn't move the wallet.dat file around to sign between computers as you would with the PSBT ones. Of course it's the same thing: never move the wallet.dat file around if it's not fully encrypted with a third party software.

Go Kano! anyway, whoever making these custom firmware and charging fees to the miner should give some of the fees to KANO for his contributions to the cgminer or donate for a good cause ![Huh](https://bitcointalk.org/Smileys/default/huh.gif) Also wander any antguardian type software distribute cgminer? or they just use API and not subject to GPL?

thank you for sharing the Lesson Learned. Buy INSTOCK item ONLY if possible, direct from the manufacture. Bitmain seem to sell S19 from stock with shipping in 5 days now Finally ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) miner arrived = happy customer = all mischief forgiven ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) Just to be perfectly clear (highly suggested this a few post back): NOT a happy customer, all is NOT forgiven. Per one online calculator, I've lost about $780/month in profit. Times TWO presuming they shipped at their maximum advertised 14 days. So ~$1500 in lost profit... no, NOT happy.

Question be is this acceptable to you or to anyone else? Second Question be was the sales term stated fiat based settlement when you pay with the cryptocurrency at the time of the payment is received? Its been a month now. I've swapped a number of e-mails, many with a "please reply so we can solve this today" that I don't get an answer to when I reply. Seems like I get a different support person and have to explain things all over. Very frustrated. I've tried their ticket system, and my tickets disappear - although they tell me they are there.
Their posted number is 1-888-55-crypto, which is one digit too many. I've asked for a real phone number via chat and e-mail and haven't gotten one. Chat has been working about 20% of the time, mostly my inquiries remain unanswered.
They have also talked about refunding me in cash, when I would require bitcoin (for tax purposes - if I get bitcoin back, it was never spent - cash would count as income). Also a pisser that I ordered at $47K BTC and its now $55K, so I would not be able to buy back as much bitcoin as I sent even if I tried. It was a $31K order, so not a trivial difference.
