According to this


it seems like a Whatsminer/MicroBT M21 , and the 58 fits perfectly with 58th which we know exists, also the 7-day hashrate is pretty low which means this particular miner was only fired recently, such outstanding luck, congrats to the lucky winner of the year.

هدا يؤكد منشوري السابق, حيت ان الاستقرار لا علاقة له بالحظر, تركيا عليها بعض العقوبات الاقتصادية وايضا الدولة نفسها تقوم بحظر الكتير من طرق المعاملات المالية اعتقد من ضمنها معظم معاملات الكريبتو عبر البنوك.


هناس تفسيران لهدا الموضوع حسب علمي, الاول هوا ان الحظر على روسيا ليس على الافراد والدليل ان الدول الاوروبية وامريكيا لازالت تفتح ابوابها امام السياح الروس, بعض المتطرفين في المعسكر الغربي يدعون لحظر شامل لكل ماهو روسي ولكن حتى الان الاغلبية تعارض ذلك.

السبب الاخر هوا تقيم مزودي الخدمة لنسبة المخاطر مقارنة بالربح, فمثلا لو كان مواطني دولة ما يمثلون 30% من دخل الشركة, وحتى لو كان هناك قانون يحظره تلك البلد ولكن وكان هناك ثغرة قانونية تسمح لهم بالاستمرار  في تزويد الخدمة لذلك البلد فهنا يمكن ان تخاطر الشركة لكي لاتخسر نسبة كبيرة من ارباحها, في المقابل لو كان مواطني تلك الدولة يمتلون 1% من دخل الموقع فعندها حتى وان كان مشغل الخدمة يعتقد ان تلك الدولة قد يكون عليها عقوبات في المستقبل فسوق يحظرها مسبقا لتفادي اي مشاكل.


في الواقع الكتير من المنصات والمواقع تحظر مواطني ولايات معينة في امريكة ولا تحظر جميع الامريكان, المسئلة معقدة جدا والسائد هوا ان البلدان الصغيرة والتي عليها اي نوع من العقوبات مثل الدول الموجودة في القائمة التي ادرتجها حضرتك سكون ممنوعة بالرغم من اني متأكد بنسبة 90% انك لو سئلت الشركة على اي اساس تم حظر تلك الدول فلن يقدمو لك اي اجابة, فمعظم الدول المذكورة العقوبات فيها مفروضة اما على حكومات او جماعات مسلحة فقط, وفي حال استخدام مواطن عادي للخدمة لن يعرض الموقع لاي عقوبات, ولكن لايوجد شركة تريد ان تخاطر حتى بنسبة 1% لتقدم الخدمة لي 5 اشخاص من الصومال مثلا!.

Each pool has its own pool/work difficulty because it makes no sense for the pool to process every share your miner finds, it also makes no sense to just submit a share that beats the network difficulty, so pools want you to submit as fewer shares as possible but they still want you to submit enough shares so they can pay you accordingly.



Well, using a low difficulty pool just means it accepts more shares from your miner, which is useful in determining your hashrate faster than on pools with larger difficulty, but then when it comes to profit it won't change, because a share at 9050 diff is worth half the share submitted at 9050*2, so at 9050*100 diff you just need to submit 1 good share instead of 100 at 9050.

In some rare cases when using very slow mining hardware, using a lower diff is better since your miner might not find a larger share and won't get paid at all, but if that's the case, it means even at a lower diff your miner isn't making "any profit", and honestly, if you have to worry about pool diff it means you are using the wrong gear for the right coin.

Migrating a data center to a mining facility isn't the best idea in the world, the power consumption of miners is way too high compared to those regular servers, the bottom line is that you can't easily find PDUs that can supply 5kw per socket, most currently used PDUs will be capped at 4kw at best, so a lot of re-constructing will need to be done to be able to run 5kw gears which is why I don't think they will ever make anything like that.

Also, most data centers probably use 42U racks instead of 48u, but then, either way, going with the assumption that the average server consumes no more than 500w, we are talking about 25kw per rack enclosure (which I am sure is a very rare as most of them will not be above 10-15kw), that would hardly fit 4*5KW machines, in size of 2258cm x 750cm, a lot of space wasted.

So in terms of space and power, if a data center has access to excessive power, it would be best to just get rid of those racks and install normal mining shelves + new electric wiring, but do data centers really have any power to spare? I mean looking at the data it seems like Facebook which has one of the largest combinations of data centers only uses 50MW of power, where does that put the average data center at?

نعم اسعار بطاقات هدا الموقع مبالغ فها جدا, لا اعرف من يشتريها بهدا الثمن الا ان كان محتاج جدا لبطاقة!



لقت اطلعت على الموقع ولم اجد الكثير من التفاصيل, ولكن يبدو ان الموقع متخصص فقط في شراء البضائع يعني مثلا لاينفع في الدفع للاشتراكات وغيرها, هل لديك اي فكرة حول هدا الموضوع؟


لا اعتقد ان للاستقرار اي علاقة بالحظر, في العادة الحظر يكون وفقا لعقوبات امريكية " يسمونها دولية طبعا " او اوروبية, النوع الاخر من الحظر هوا الحظر المحلي حيت تقوم الدولة نفسها بحظر هده التعاملات وهنا تكون هده الشركات عرضة للمسائلة القانونية في حال توفير الخدمات لبلد قوانينه تمنع ذلك, الجزء الاخر من العقوبات يأتي من باب "الابتعاد عن المشاكل" فالكثير من الدول لايكون عليها عقوبات تتعلق مباشرة باستعمال الخدمة واحياتا العقوبات تكون على الحكومة فقط "مثلا بعد انقلاب عسكري" احيانا تكون العقوبات على افراد محدودين او جهات معينة وبعض مزودي الخدمة يقومو بحظر شامل لتلك البلد تفاديا للمشاكل.

لقد مر اكتر من عام على اخر تحديث لهدا الموضوع ولازالت البطاقات الصادرة من هدا الموقع تطلب تعريف هوية, هل يوجد موقع اخر يقدم بطاقات افتراضية بالبتكوين ولا يطلب اتبتات هوية؟ اعتقد ان الاخ omega ملم بهده المواضيع وربما يكون لديه تحديث بالخصوص.

I don't think so, my guess is that U.S large corps are only "playing" with BTC and they are the ones driving the difficulty against its "natural" direction where the other coins' difficulty is simply responding to the price drop and the overall profitability.

Since these prominent players are playing the game "professionally" and use the most efficient gears, it would take them months if not years to react to the pain, whereby all the other smaller coins are mainly mined by small guys who can't sustain operations at a low profit.

My prediction is that the large U.S corps will continue to grow at the expense of smaller miners leaving, which would somehow slow down the inevitable increase of difficulty, eventually, the market won't have enough room for all of the large U.S corps and then it will become all about "the survival of the fittest".

That whole picture I painted above would vanish if we somehow started another bull market and expanded the size of the room to fit everyone, I think all the misery that we could expect for the rest of this year and 2023 will only be enough to hurt the small guys, the event that really matters would be the halving of 2024. if the markets don't recover pretty well before that hits, many of those large corps will fall.

 

Good stuff, I honestly believe that the future of home mining will be these small USB sticks that make no noise and generate almost no heat, and yet, they have the chance of hitting a solo block, I don't want to go into details on how I think every small miner with 10 or 20 ASICs in their garage is going to be forced to shut down as that would be off-topic I am just protecting that in 4-5 years, it's either you have a few tens of millions to be able to buy a few water-cooled pre-setup containers or get your self a small tiny device like this and try to hit the lottery, everything in between those options will vanish.

So the summary of the above paragraph, I believe if this turns into a mass production product like Apollo or Newpac, it would very likely be something in the future.

Now with that being said, why did you choose the BM1387, why not the BM1397?, they have double the efficiency and are more widely available in terms of 'second-hand', because the failure rate for the gears that use BM1397 is way above 50% (not a problem with the BM1397 itself), so for any sort of mass production when it comes to cost, the BM1397 beats everything else.

Also, on a side but related note, should you need to source chips from China in large quantities, reach out to me, and I will connect you to the right people.

Check with LoyceV, he downloads all block data and get probably pull that with a single query, but anyway, despite my admiration for your interest in learning all this stuff, the question is pretty much unrelated to the current topic, in fact, most of miners couldn't care less how all of this mining stuff work, if you want detailed technical answers, just post in this section

They are likely the s19 pro hydros, those do about 200th at 27w/TH stock settings, so squeezing an extra 45th at 23w/th seems very reasonable given how much the stock settings suck.

Imagine what the xp hydros custom setting can do.

How bad did i say it was going to be? Please link my post i am on my phone got some issues with my pc.

Anyway, look at this https://youtu.be/8QZAGpssUe0

The big boys have started to play with thier hydro gears, i need to revisit my last prediction and add a bit of more salt on it.

This would be a problem for many large miners, most mining PDUs out there use c19 sockets, the largest PDU i saw was rated at 4.1kw max per port at 220v.

They use a split cables c19 to 2*c13 to run Bitmain gears and c19 to c20 to run Whatsminers

The most common set up is 24 ports, so one PDU, 24 gears, max is 4.1kw they use 3.5kw at most so pretty safe.

Pushing past this will cause two issues.

For Whatsminer since they use a single PSU, you need to change the PDU (about 600$ for managed metered and 300$ for basic).

For Bitmain, you can use the same PDU with no split cables but then you lose half the number.

 Besides, all the cables running from the distributer box will likely need to be re-sized, thats a ton of work.

Besides running 5kw will probably require 3 phase set up, so all in all, i can only see them do such a thing with things like the s19 hydro where you buy the whole package pre-wired and just feed 3 phase wires to the container, but using these existing set up will be very costly for most people.

Only they know, or maybe if some large pools leak such data then you can get a good estimate of how much hashrate they have, the pool should know which "firmware" is responsible for every x amount of hashrate, but anyway, I personally couldn't care less, I just hope they are making  enough profit to keep their operations on going, competition in this market is very good for us as miners.


Sure thing, I'd imagine writing the first CPUminer was a lot harder than anything else that came after it, but still, it's very costly and time-consuming to do it even now.

ماذا تقصد باحتيال؟ اعتقد انك تتكلم عن مايعرف ب "التعدين السحابي" وهي المواقع التي تطلب من المال لاستجار اجهزة تعدين, او تلك التي تطلب منك تحميل برامج معينة على جهاز الموبايل او الكومبيوتر, نعم كل تلك البرامج هي عمليات نصب او على الاقل مضيعة للوقت, اما اجهزة تعدين البتكوين فهيا حقيقية وتذر مليارات الدولارات من الارباح على المعدنين, طبعا يوجد عدة عوامل معقدة لتحديد جدوى اقتناء وتشغيل تلك الاجهزة لان الكسب منها ليس للجميع.

You should always assume that the arrangement might have changed at some point, I think the best practice I try to stick to when trying to help someone identify which board is which is to ensure that I mention "if the arrangement is factory default" so really, the best way to tell would be to check where the ribbon is going to/from, that way you won't unplug a good hashboard and leave the bad one in.

They are making profit off of it, most custom firmware with added features like auto tune charge fees and make some good money, crowdfunding would make sense if someone was working on the original cgminer or coding something new while adding all these features and not taking firmware fees.

Yet "some mining pool's owner" has no issue allowing all the new miners to mine to his pool as long as they use stock firmware, not only do they violate the Cgmier license, but they also have no proof of actually finding blocks just like most other custom firmware, cherry-picking the people you want to lecture is fine I suppose, as long as you don't mess with the big boys like Bitmain, Whatsminer, and Canaan your pool is relatively safe, meanwhile, practice all of your morals and on the little guys. 

You are free to post here (you did anyway) but I can't add you in the original post because none of the trusted community members can vouch for you, I did search you a bit on large telegram groups, and also nothing came up, I am not claiming anything here, just saying, I hope that someone can verify you and report back so I can add you to the list, until then if anyone wants to deal with you, they will need to take the risk first and then report back.

Thanks for understanding.


This topic is for repair, not for after-sale services related to buying mining gear from you, if I don't buy your equipment, will you fix mine? if yes, you can post here, if not -- you can't.

Thanks.

I had the same issue with some cheap fans I bought, they were reporting 30k RPMs and then suddenly fan lost, i could not get them to work on stock firmware, I remember someone mention about cutting one of the wires but i did not bother to try it, so you might want to look into that direction.

Gave you merit for reporting back, very well done.

So what caused the EEPROM issue? as far as I know you can't edit it without a specific tool like the code editor, the control board itself has noway to write onto it, so what went wrong? did the issue happen after a power cut? firmware flash? or just randomly.?
