ماهده الحنية والخوف على اموال المستتمرين؟ ثم هل اطلعت هده السيدة على خسائر المستتمرين في الاسواق (المحمية) ؟


1- سوق S&P500 وهوا اكبر سوق بورصة امريكي



2- سوق الNasdaq وهوا تاني اكبر سوق في ومقره نيو يورك "نفس ولاية هده السيدة"



3-البورصة البريطانية (اسهم اكبر 100 شركة)



4- البورصة الاوروبية ( اكبر 50 شركة اوروبية)




5- البورصة اليابانية ( اكبر 225 شركة في اليابان)



6- عقود النفط (محمية جدا حتى انها في الواقع وصلت قيمتها بالناقص العام الماضي   )





7- الذهب (الذي يروجون له انه ملاذ امن )




كل هده الاسواق ياسادة (محمية ومؤمنة ومقننة وامنة على المستثمرين) , هل تعلم هده السيدة ان عشرات الشركات بل احيانا مئات الشركات يتم الافلاس بها عن طريق ال shorting في اسواق البورصة الامريكية ؟ هل تعلم ان شبه كل الشركات الصغرى تقف على "قرن ثور هائج" ومعرضة للخسارة والزوال وخسارة اصولها عندما يقوم 5-10 من مديري الاموال ب "شورت" لاسهمها؟

ماذا تفرق هده الاسواق عن البتكوين والعملات الرقمية من ناحية الخطورة على المستثمر؟ كل انواع الاستثمار فيها خطورة ومن لايريد مواجهة تلك الخطورة يمكنه وضع امواله في البنك او دفنها في حديقة المنزل او تحت البلاط, لا احد يتم اجباره على الاستتمار.

If you changed the default password for the miner you need to change that in WhatsMiner Tool as well, go to settings > current password and enter the correct password.

The hashboards are sockets are labeled on the control board, just follow the ribbon cable from the hashboard to the control board and you will see each has a number, ignore the number as it's sometimes different on the 17 series but focus order, for an example if you have J4, J5, J6 on the control board, and 1,2,3 on the miner status page, J4 will 1, J5 will be 2 and J6 will be 3.

To double-check you can just unplug the cable that goes to the board and then power the miner on to check for any changes.


Yes, the kernel log has some useful info in it. You should never buy mining gears off Alibaba and Aliexpres.

It tells you that you and that person are trying to reinvent the wheel, the kernel log will tell you exactly which hashboard is dead, in fact, it even appears in the miner status (the very page that tells you which 2 hashboards are working fine), if you can't figure that out - paste the kernel log here and a screenshot of the miner status page.

I also do believe that we will eventually hit 500k but that is a very long term target for me, also mining space gold is something I take with a grain of salt as I don't see that happening in the near future, probably not while I am alive, those events are very far away and I don't think they hold much value for now, I am focusing on the current cycle we are in.



Every candle here represents 3 months worth of price data, you see that we spend the majority of time in the lower green area, this is how things have been since 2013 and I see no reason as to why this would change, if you look at the right side of the chart I drew an "imaginary" future candles, those are a replica of the last cycle candles, the chart suggests that in the next 3 months candle we should be in the red zone, with the potential price of as high as 195k before reverting back to our "median" channel with the color green.

The theoretical bottom for the next cycle should be at around 50k and will come at the second half of 2022, but for the entire year and the last quarter of this year the price should be at around 60-80k and we won't make any new ATHs until 2024.

I also believe this analysis model is a bit too optimistic because it doesn't take "diminishing returns" into calculations, so I think of these numbers as the ultimate most optimistic bull scenario.

You have two bad chains, only J6 is in perfect condition, J7 should/might work with a bit less hashrate, but J8 is dead, you could go ahead and do all the troubleshooting Phill recommended but my guess is that hashboard is dead. it's not uncommon for used miners, where did you buy it from?

Phill are you still holding on to your last year's predictions for the difficulty?  Do you see us go to 35-40T by the end of this year?

While i am not completely against the potential 100k or more theory i highly believe that won't last for long, in all previous cycles we tend to spend the most time at below 50% of the ATH, the last cycle we spent most of the time at about 6-8k before making a new time high, so maybe 40-50k will be the average for the coming years. I need to do more math and chart analysis on this.  

We are almost 1500 blocks into this round and we are lagging, so a negative adjustment is very likely.


This is good news for miners, despite the price drop, back around the end of October we were at a difficulty level of 18.8T and a price of 10k bitcoin, we are now 400% up in terms of price but only 16% up in terms of difficulty.

This means if you used to make 0.1BTC a month you now make 0.084BTC, but instead of that being equal to $1000 it's now worth $4,200, which is 320% more profit, I guess most of us have not witnessed such great times and will probably never will after this.

Then it is not tuning at all, tunning should have a fluctuating hashrate rate, it would settle down at one point before it drops again and then attempt to go higher or lower than the previous high, the intervals will pretty much depend on how the firmware is coded, but you should see fluctuation in the hashrate every couple minutes.


Good luck, hope this works.

الموضوع هدا متفرع ومتعدد الجوانب, ولا يمكن الاجابة عليه بصغة مباشرة ويجب فهم مبداء ماهوا التأكيد اصلا؟

ان سئلتك كيف تتاكد من تحول وصلك سوف تكون اجابتك " بالاطلاع على المحفظة التي استخدمها وعندما ارا انه يوجد تأكيد على التحويل يعني وصل وكل شي تمام" ربما تكون اجابتك " ادخل على blockchain explorer واضع عنواني واشاهد التأكيد"

مايحدث هنا هوا انك تقوم بسؤال محفظتك التي بدورها تسئل العقدة المرتبطة معها والاخيرة ترد "نعم هدا التحويل موجود ولديه مثلا 5 تأكيدات", مما يعني انه يمكن ان تكون كل العقد رفضت هدا التحويل الا عقدة المحفظة الخاصة بك في وقت تظهر لك المحفظة ان التحويل لديه 100 تأكيد مثلا.

لهدا السبب لايمكن ان تجد حوض تعدين او منصة او اي كيان يتسقبل بتكوين يعتمد على المتصفحات التي يستخدمها سائر البشر بل يقوم بتشغيل عقدة خاصة به, العقدة الخاصة بك لن تكدب عليك ابدا, على عكس العقد الاخرى, فلو تمكن شخص من اختراق متصفح blockchain.com يمكن ان يظهر للجميع ان ساتوشي قام بتحويل مليون بتكوين لعنوان اخر مثلا بينما هدا التحويل لاوجود له في العقد الاخرى.

طبعا العقد الصادقة تقوم بحظر العقد التي تقدم "بيانات مخالفة" وفي العادة كل العقد النظيفة تحتوي على نفس السجل مع فارق بسيط في المزامنة, ولكن يمكن فعليا ان يتم النصب عليك عبر اظهار تأكيد زائف على محفظتك لتنصدم لاحقا عند محاولة ارسالك للمبلغ ان كل العقد الاخرى ترفض ذلك التحويل.

لذلك بالمجمل عدد العقد التي تتفق على تحويلك في النهاية هوا امر ليس مهم على الاعقل في صلب هدا النقاش,طبعا في حال تم فعليا قبول تحويلك في بلوك س وتم البناء عليه ورفضته 40% من العقد سوف يحدث انقسام وتصبح كل مجموعة عقد تمتلك بلوك تشين خاص بها.

لهدا السبب الكثير من المنصات تعتبر تأكيد 1 غير كافي لانه يمكن ان يكون هناك تضارب في احد البلوكات بين الاحواض مثل ماحدث مؤخرا بين F2pool و Slushpool حيت تمت عملية "انفاق مزدوج" وظهور تحويل بتأكيد 1 من الكثير من العقد الرئيسية المعروفة تم اختفاء هدا التحويل فجاءة, يعني يمكن جدا ان ترا تحويل لعنوانك بتأكيد 1 ومن ثم يختفي, يمكن ان ترا 5 تأكيدات تم يختفي, طبعا فرصة حدوث هدا الشي ضئيلة جدا, خصوصا بعد تجاوز 1 تأكيدة.

نعم باستعمال محفظة تدعم ذلك يمكنك فعل كل هدا..المحافظ البدائية لاتوفر هده الخصاص وتقوم بحجب ال output التي تم اضافتها في التحويل بمجرد انشاء التحويل.

Why would they do that? it's probably hidden somewhere, try to inspect the main page and look for hidden pages/tabs.


Can you attempt a hard reset using the reset button on the control board?

The cheapest would be the black glue from China, it's available on both Aliexpress and Zuesbtc > https://www.zeusbtc.com/RepairDetails.asp?ID=86, keep in mind that this product can't be stored outside the fridge for more than 10 days, so check with the seller as well as the carrier, the second option which is a lot more expensive but probably has better quality and easier to get would be Arctic > https://www.amazon.com/Arctic-Silver-Premium-Adhesive-ASTA-7G/dp/B0087X7262.

wndsnb also mentioned using a different product somewhere which I can't find, I hope he would chime in and post the link

الشرح مبسط وجميل جدا, الا انه يوجد بعض الاخطاء فيه واهمها هوا قولهم ان جميع العقد يجب ان تتفق على صحة التحويل, وهدا غير صحيح, لو كان الامر كذلك يمكن ان انشاء عقدة ترفض جميع التحويلات وبهدا يتوقف البلوك تشين كليا.

ايضا مفهوم انه في حال تم رفض التحويل فكأن التحويل لم يحدث هكدا ينطبق ايضا على pending transaction اي تحويل لم يسجل على البلوك تشين اي انه لايحمل على اقل تأكيدة واحدة فهوا لم يحدث والقيمة لما تغادر عنوانك حتى وان كانت موجودة على mempool كل العقد.

انا ايضا اتمنى ان يقوم شخص ما بهدا الشرح بالعربي.

Please use the code function to paste the kernel, something like this


The above example also shows that fan 5 is bad, reporting only 1200rpm which won't allow the miner to start, while this could be caused by the fact that you flashed a different firmware, it likely needs a replaclement. So replace fan 5 and then repost the kernel log, it will be a lot clearer without a fan error in place, however, chances are you are going to end up Sdcarding the miner and installing the T9 firmware version.

it's $400-500 now in China, depending on the quantity and your resources, so I think that is a good buy? I don't know!


Not a huge difference, the ones with higher hashrate have slightly better chips overall, but the difference is too small to be considered.


Lifespan for all miners is really random and luck-based, it could be 1 month or 5 years, I usually take 6 months or less into account, I assume they will break and die by then, although I have some gears hashing just fine for 4 years, some died in 2 days, you can't really tell.

We create a whole topic for difficulty predictions, we all have different things to say, my prediction is a slow and steady increase in difficulty until year-end, no skyrocketing what so ever, check the topic by NFW to see my predictions and the reasoning behind it,  keep in mind, I made more wrong predictions than I remember.  


If you can find an S9 for $300 ready to ship, that would be a deal given the current market price, at 6 cents you need this price mania to keep going, once things cool off you won't be profitable with an S9 at 6 cents, but until that happens, you should be good.


BraiinOS, Vanish, and the mods that thierry4wd make are the only ones I would trust.

And, forget about liquid cooling, it's economically useless, unless you get it for free it makes 0 sense unless you want a very quiet set up or plan to make some youtube videos or to impress the fellow ladies miners then anything except the default air cooling will come at a cost which will put you at a higher risk of losing more money, in plain English, ditch immersion cooling all together if you plan to actually make some profit.


NFW probably thought it's the K version which is indeed a terrible gear to own, you can see me "nag" about them here, the S9j is a robust gear, nowadays it's even better to buy the J than the original S9 because the latter is a bit too old, the problem is, some resellers will swap the old S9 hash boards into an S9j miner or simply change the sticker, and you can't really tell the difference, this is why if you don't trust the seller you should go for the S9i which is as robust but has different dimensions and thus can't be faked.

What is the chain error? copy and paste the kernel log here.

This could a firmware issue, while T9, T9+, and S9 (all models except the k and SE) use the same control board, each has its own firmware, just like how T17, S17 and S17 pro use the same control board but you can't run a T17 with say the S17 pro firmware, I do not have T9 to test but I'd guess the same logic applies, so you need to get rid of that T9+ firmware using a Sdcard and then flash the T9 firmware ( I included all links in my previous post)

BraiinOS isn't a bad choice at all, it has a plus to it which is the no-fee version, however, depending on the frequency of your restarts you might need to use the fastest firmware to reboot which might or might not be BO, how often do you think you will need to restart the miner based on the current PV readings you have? I know it will depend on a lot of factors but you should have a rough estimate, I am afraid too much rebooting might damage some stuff.

You flashed the recent firmware from bitmain which is a one-way street, you will need to use the recovery file and an SDcard to revert back to an older version, you will need to find the T9 recovery firmware which is no where to be found, but I believe you can use the T9+ files since they both use the same control board, this very version is what we use on the S9/S9i and S9j as well.

I don't know someone who did "exactly" what you aim to do, but the path to it is similar, for example, I used AwsomeMiner to underclock my miners and increase the fan speed in the afternoon in the summer, it was an easy set-and-forget approach, some people have an auto turn on/off based on some other inputs, all that AwesomeMiner and the other paid software do is send an SSH command to perform all that, so the method to what you need is exactly the same except that you will be using different parameters for your script, I use time and miner temp, you will use the data output from your PV system, so this isn't going to be difficult IMO.
