To run a 2MW you are going to need a lot of money, the infrastructure alone will need at least 150-200k per megawatt, and you will need to hire a professional to set up the network security aspect of the farm.

As for the permanent staff, you will need at least 2 trusted folks to take care of the farm, they will need to have a general knowledge about electricity, IT and know how to use screwdrivers.

If you don't have the time to manage the farm, you will also need to hire someone for that task as well, whoever person you hire to work at the farm will only change a bad PSU, replace a couple of miners' fans, change the filters and that's it, but when a breaker is down, or one large exhaust fan is broken, they will need to report that to the manager, the manager needs to call someone to handle that.

You can save up on the cost if you would build everything yourself, but I tell you this based on personal experience, once you go past 100-200kw you are going to have a rough time dealing with airflow/heat, and you will understand after it's too late that the initial design of your farm was actually wrong, and you will need to rebuild many things, so just take a short cut and buy the ready to install mining containers even if they were 2x more expensive than setting up your own.

alternatively, you can just sell your power to someone who has enough money, experience, and staff to run the farm, you can probably sell it for 3 cents and make 30k a month doing exactly nothing.

ملخص مايحدث في الولايات المتحدة هوا محاولة فك اترباط عملات الكريبتو بالدولار, والحرب الان بين السلطات الامريكية والعملات المستقرة, حيت انه وبعد ما حدث لعملة لونا المستقرة اسنت الولايات المتحدة قوانين وضوابط جديدة بخصوص العملات المربوطة بالدولار, شركة متل باكسوس مسؤلة عن عملة BUSD و ايضا عملتها الخاص USDP و ايضا عملتها الجديدة المربوطة بالذهب, بالاضافة لكونها قدمت اوراقها للحصول على رخصة مصرفية تمكنها من تمارس جميع النشاطات التي تمارسها البنوك العادية كل هده الاسباب وضعتها تحت المجهر في محاولة لايجاد اي ثغرة لتغريمها او اغلاقها.


انصح بقراءة هدا المقال الذي يبين رغبة الولايات المتحدة في تحطيم مجال الكريبتو https://bitcoinist.com/us-government-secretly-cracking-down-crypto/

I think I can answer your question, in a 3-phase system, there is a limited amount of amps on which you can draw on each phase, you can't just move the load from L1 to L2 and expect everything to work unless the wirings are oversized, and by oversized, I mean doubled, it's also pretty damn stupid for the power company to cut just one phase at a time, it puts extreme pressure on their transformers, every transformer I saw is protected by a phase failure relay which will shut down the low end of the transformer when one of the phases is absent.

With that said you have two options:

1- Split the cold/hot side of the miner using a split room design, so you have a cold aisle and a hot one, you can use sheet metal, MDF or foam board, this will prevent hot air from entering the cold side as it will have to pass through the heatsinks of the "OFF miners".

2-Create a negative pressure zone on the exhaust side by adding an exhaust fan attached to the wall which faces the miners' exhaust fans, air moves from positive to negative, so even 2 rows off, the air will still go from the cold side to the hot side.

It was a drop of 0.49%, the hashrate picked up in the last couple of days, the average block time for the last 3 days was 9.2 minutes, it seems like the price increase from 16-18k to 22-24k brought some people back to business.

it's also clear looking at asic prices and watching the resellers' stock, gear prices went up, and demand went pretty high, not sure if it's the 2-4k increase itself or the FOMO, I believe it's the latter, seems like some people are trying to rush before the market hits the sky and BTC goes to the moon, since the price increase, we had one positive adjustment, this one is almost flat, the next will likely be a slight positive if price stays the same.

Where does it fail when you set these numbers?

Also, looking at the tank you posted it says 12kw cooling capacity, no mention of the 6kw, which means it can safely run two MicroBT even overclocked, unless I am missing something.

Yes, you want to keep the power mode on normal when setting a power limit on the miner, it's almost impossible to bring the miner to an exact figure, so your 3050w limit will usually be slightly less, a few watts here and there, also, the power consumption on the tool isn't 100% accurate, so make sure you use a wattmeter to get the exact correct number.

I would also look for a different tank, 6kw is too much for Antminer and a bit on the low side for 2*Whatsminer, but at the end of the day, the lower you go on these Whatsminer the more efficiency you gain overall.

Also if the project kicks in and you want to sell the package as a 200th miner you would want to get the M50, they range between 25w/th to 28w/th, the lower the more expensive of course.

The M50s 110th 28W would be a good pick, it should do 110th at 3080w default, so if you want it to stay at 2900w (to not go above 5800w for the tank) it will do 103th or a total of 206th for the tank.

Meanwhile, keep in mind that you will remove fans in the tank, the reading on the wattmeter will take the fan readings too, the fans in the pics you posted are running close to full, they consume about 85w each at full speed (7k rpm), so the reading on Whatsminer tool will be a lot more accurate when the miners run in the tank.

Keep in mind the low power mode will tune every miner differently, also, inside the tank temps will be a lot lower and thus the tuning might go higher because it does use temp as a measure of how low/high the frequency goes.

Long story short, using the power limit is safer when you really want an exact watt per miner.

Glad they arrived, you can not test the high with air cooling, low will work fine and cool, also you can download whatsminer tools and set power limit for each miner, like 3000w it runs a lot cooler with reduced hashrate.

About 4 days left for this difficult epoch, currently, the numbers are



So very likely a drop of about 3%, this will kind of offset the last diff increase of 4.6%, as for the price, it seems to have hit a wall at 24k and we are stuck below that, for those who still want to buy coins or mining gears and have the cash to spend, it would be great to see another drop below 20k, that will make buying mining gears a lot easier.

The fact that she came to the right forum and the correct board suggests that she knows the difference between an asic miner/GPU and a pickaxe.


OP, save the day and post an image of the stuff, you can use this website to upload pics > https://imgbb.com/ and then copy-paste the links here.

I would also agree on what the other folks mentioned about not taking this to private messaging, keep everything as public as possible, in case you finds some long textx that looks like a bitcoin private key



or seed phrase that consists of 24, 18, or 12 words, never post any of those online, learn how to safely extract the coins from the wallet and then either exchange them for fiat or store them safely, aside from that you should be safe until you figure this out.

Sorry for your loss.

في الواقع هده الخطوة كما شرحت في المنشور السابق هي خطوة اجبارية وتعتبر بمتابة الخطوة التي تتخدها الدولة عن الوصول الى نهاية النفق بالرغم من ان النهاية واضحة من بداية النفق, الان سوف يتقلص الفارق بين السوق الموازي والسعر المركزي الى شبه الصفر في حال كان المركزي كان بالفعل لديه مايكفي من الدولار لشراء كل الليرة المتداولة بسعر 6650, في حال فشله في ذلك فسوف تعود الفجوة للأتساع ويزيد السعر في السوق الموازي مجددا حتى الوصول الى مرحلة التشبع وتساوي الطلب بما يوجد في حوزة البنك المركزي وعندها سيستقر السعر.

طبعا سيكون الدولار في السوق الموازي دائما اغلى بقليل من سعره في البنك حتى في الدول المستقرة, نظرا لان الكاش في اليد افضل من البنوك, لاسباب كثيرة منها الخصوصية, التهرب الضريبي وغيره.

اتمنى ان لانكون قد تطرقنا لموضوع بعيد عن صلب المنشور الاساسي, من وجهة نظري الواقع في سوريا يحاكي الواقع في نيجيريا وغيرها من الدول التي ارهقها الفساد والحروب, نسئل الله ان يرسل الامن والامان والرفاه لاخوتنا في سوريا, اتمنى ان يكون الاعضاء السورين في امان بعد الزلزال, دعواتنا لكم.

I think the update would only require a change in the payout system and would have no affect on the process of finding and submitting blocks. Just a matter of how you distribute the block rewards based on the % set by each user.

This would benefit those who own large gears like sub 100th, they do not want to gamble with it all, so maybe half for pplns to pay the power bill and the other half for solo mining, while it is very unlikely for me to use the split function I can see many people appreciating the change.   

هناك نقطة غائبة عنك اخي, واعتقد انها غائبة على الاخ يحى ايضا, وهي ان التجار يشترون الدولار في صورة اعتماد مستندي او مايعرف ب documentary credit او letter of credit, وهدا يعني ان التاجر يقوم بمراسلة مصنع ما في دول ما, ولنقل مصنع ملابس في الصين, يقوم مصنع الصين بارسال فاتورة معتمدة من مصرفه للتاجر السوري, يقوم التاجر السوري بتسليم الفاتورة للبنك في سورية, البنك يقوم بتحويل الاوراق للبنك المركزي السوري, ويتم فتح مايعرف بالاعتماد بين المصرف السوري والصيني وهوا بمتابة عقد او escrow بين البائع والشاري.

عند استلام البضاعة في سوريا سواء عبر المطار او المواني, يكون لذا مصلحة الجمارك علم مسبق بالبضائع المحملة بالتفصيل, عندها يتم اقفال المستند ويتحصل البائع على امواله من مصرفه (احيانا يتحصل على امواله عند شحن البضاعة ووصلولها لمناء او مطار المغادرة من البلد المصدر بعد تأكيد شركة التفتفيش على كميات البضاعة ومطابقة الفواتير).

بهده الاجراءات تتمكن البنوك من التأكد من ان اي تحويل يتم عبرها يكون في مقابله بضاعة, طبعا هدا الطبيعي في حال كانت القوانين تطبق حرفيا لا يوجد فساد, ولكن ما في دولة مليئة بالفساد مثل سوريا يوجد حيل اخرى يلجاء اليها التجار.

يقوم التاجر السوري بمراسلة مصنع في الصين او تركيا او اي دولة فيها فساد متفشي, يتفق مع التاجر بارسال فاتورة بمليون دولار, لبضاعة في الواقع قيمتها فقط 500 الف دولار, وعندما يقفل الاعتماد المستندي يتحصل التاجر التركي او الصيني على 500 الف اضافية, يعيدها في صورة كاش او حوالة مصرفية عادية للتاجر السوري في مقابل مثلا 50 الف دولار, هنا التاجر تحصل على 450 الف دولار في مقابل 50 الف دولار اي بخسارة 10%, ولكنه لايزال رابح.

يقوم ببيع ال 450 الف دولار في السوق الموازي  مثلا ب 7000 ليرا للدولار, ليتحصل في المقابل على 3,150,000,000 ليرا , بينما كان قد اشترا مبلغ ال 500 الف دولار من البنك ب 3500 ليرا للدولار اي بقيمة  1,750,000,000 , يعني حقق مكسب بقيمة -1,400,000,000 ليرا بدون اي تعب ولا بيع بضاعة ولا شراء بضاعة ولا اي شي من هدا القبيل, وحتى عند استراد البضاعة سوف يسعر البضاعة بسعر اقل بقليل من سعر السوق الموازي حتى لايتسنى للتجار الاخرين الذين لايمكنهم فتح اعتمادات مستندية عبر البنوك من منافسته في تجارته.


طبعا هده مشكلة اقتصادية معروفة مرت بهدا عشرات الدول من قبل, الحكومات الغبية تكرر هده الاخطاء مرارا وتكرارا دون الاستفادة من تجارب غيرها, وهدا مانراه في سوريا ومصر ونجيريا وغيرهم, الحل الاقتصادي الوحيد هوا القضاء على الفجوة في فارق السعر بين السوق الموازي والذي يمتل القيقة الحقيقة للعملة والسعر الرسمي في البنك المركزي والذي يمثل القيمة المفروضة وهي في العادة افتراضية.


 البنك ليس مفلس تماما ولكنه لايمتلك دولار يكفي لبيعه بالسعر المخفض او الافتراضي لكل من يريد ان يشتريه, فأن كان هناك مليون ليرا متداولة وانت حدث سعر بيع الدولار = 1 ليرا اذا يجب ان يكون لديك مليون دولار في البنك, ان كان لديك نصف مليون دولار وقمت بتحديد سعر 1 دولار = 1 ليرا هنا تلقائيا سيتكون لديك سوق موازي بسعر مخالف.

طبعا القضاء على هده الفجوة ليس بالامر السهل, لان الكتر من مؤسسات الدولة مثل شركة الكهرباء, الطيران, الوقود و و و لازالت تتحصل على سعر مخفض من البنك, وعند توحيد السعر بالسعر الحقيقي سوف تتاتر اسعار الخدمات والبضائع فورا, وهنا يتوجب زيادة في المرتبات, وبعد التعديلات الجوهرية, لكن هدا هوا الحل الجدري الوحيد, لانه بوجود سعرين تكون الاستفادة ل 1% من البشر على حساب ال 99% الاخرين.

The idea sounds interesting, personally, I don't see myself using it, but I am sure many others would.

I think it would be best to leave the default current port and password "x" for entirely solo mining (aka 100% solo) for the reasons below.

1- Some people who have gears pointed to solo mine on ckpool and do not follow this thread, Twitter, or anywhere else where they would know about the change.

2- Changing The miners that are currently set up would be a pain in the ***, personally,  I have set up ckpool with a default password on a few hundred gears as a secondary/backup pool, and have done this for probably 6-7 clients who said they want to try for solo when their main pool is down, it would be a lot of unnecessary work to reach out to all of them again.

Of course, doesn't take too much to realize that my suggestion is biased as hell, but I still think it makes sense.

لا يمكن ان يحدث الشي لان وجود سعر موازي لسعر البنك المركزي يعني عدم توفر الدولار للعوام في البنوك، ولو كان بأمكان اي شخص شراء دولار بسعر  460 فيمكنه بيعه في السوق الموازي بسعر 750 وتحقيق مكسب 63% بكل بساطة، بل يمكنه تكرار العملية الاف المرات حتى يحني مليارات الدولارات من الارباح.

لويوجد اي داعي لشراء البتكوين والخوض في هده المتاهات، فقط قم بتبدليل دولار بنيرة لتحقيق مكسب.

لماذا لا يحدث هدا الشي ؟ لانه لايوجد دولار في البنوك بذلك السعر، وحتى ولو وجد فسيكون محدود جدا وفقط قلة قليلة من الناس يمكنهم الوصول اليه عبر استخدامهم الفاسد للسلطة.

It's not worth the risk and the effort, if I join you with a single S9, our chances will double, but it's still 1 in 8 million chance as opposed to 1 to 16 million, on the grand scheme of things, that's nothing compared to the risk you have to take, you could also get scammed by the end of the day.

كلام الاخ Husires صحيح تماما, القصة وبكل بساطة ان سعر صرف النيرة (عملة نيجيريا) حسب البنك المركزي $1 = 460 نيرة, بينما في السوق السودة او السوق الموازي فالدولار الواحد = 750 نيرة, يعني بزيادة تمتل حوالي 63% , ولو قارنا هدا مع سعر البتكوين فان زيادة نسبة 63% في سعر البتكوين الحالي ستكون 38,000$  لاي شخص يمكنه شراء دولار بسعر المصرف, مما يعني ان كل هدا الكلام لا معنى له الى لشخص يمتلك بتكوين, يقوم ببيعها بالنيرة في السوق السوداء, وتم ياخد النيرة ويدهب للبنك ليشتري بها دولار بسعر صرف 460.

اعتقد انه يمككنا تطبيق هدا الكلام على اي بلد يكون فيها سعر صرف الدولار بين البنوك والسوق السودة مختلف بشكل كبير, مثل ماحدث في مصر في الشهر الماضي اعتقد اني قرأت انه كان هناك فارق 20% بين السعر الحقيقي في السوق الموازي وسعر البنك المركزي.

The mentioned mine uses 90% "clean" energy, so it does not seem to be carbon emission issue, seems like DaveF is correct, they just want to kick these guys away in order to build other things.


I hope everything works out great.

@stompix paying nearly 0.3BTC for a single miner is just stupid IMO, not to mention how bad all the numbers are, it's just way too risky to put that much in a single gear.

So far, it looks like we may stay close to flat


It looks like New York state is kicking miners out, this article says the judge issued a $10,000 daily fine against one of the mining farms, aside from all the media talk, can someone sum up what is going on in NY in regards to mining?

If you walk into a coffee shop and they don't charge you for the cup of coffee you drink then it's free as far as you are concerned, just because someone else pays for it doesn't change the fact, the same thing is true if you are forced by the law to walk into that coffee shop and pay 1$ per entry whether or not you drink the coffee or not.

In many places around the world,  essentials like electricity are subsidized by the government, yes the government is using your money to subsidize the electricity, but you can't ask them to give you that money in cash or give you apples instead.

Even in some "modernized" countries where power is not subsidized, some people pay for fixed contracts, say the minimum is 1000kWh and your house uses only half of that, you can't just buy 500kWh, so you are forced to get 1000kWh, the otherwise wasted 500kWh falls safely under the term "free".

OP, no hashrate is ever enough for solo mining, just like no amount of money is enough to buy you enough lottery tickets to guarantee a win ( unless you buy all the tickets which don't make you win anything anyway).

With 110Th and assuming both price and difficulty will not change, you can easily earn $250 a month mining to a PPS/PPLNS pool, in 10-12 months you will ROI the mining gear and enjoy a stable almost guaranteed income of $250, makes a lot more sense than solo mining, if you insist on trying your luck, go ahead, you might as well just hit a block, but you need to be aware of the fact that it's extremely unlikely for that to happen, you need to be freaking lucky to hit a block with that hashrate.
