ربا صدفة خير من الف ميعاد  .

سأختار رقم 9.

شكرا على المسابقة.

دراسة اكثر من رائعة صراحتا, المشكلة الوحيدة هي احتساب الاقسام الفرغية الخاصة بالعملات البديلة فهي تعطي مؤشر خاطئ عن نشاط وجودة القسم, معظم التعليقات التي تأتي في تلك الموضوع تكون اصلا من قبل بوتات او بوستات قديمة جاهزة يعاد نشرها بطريقة مغايرة, فأعتقد انه لو تم استتناء تلك الاقسام ستتغير النتائج كثيرا, ايضا مثلا في القسم العربي لايوجد spam لو دخلت على القسم الروسي مثلا وقمت بترجمة المواضيع ستجد نسبة كبيرة من السبام والمنشورات التي ليس لها اي فائدة.

ولكن بالمجمل فنحن نعاني من نقص النشاط في القسم العربي خصوصا في هده الاشهر الاخيرة, لا ادري ان كان موضوع فايروس كورونا له تأثير بالرغم من التأثير كان يجب ان يكون ايجابي لان الجميع في منازلهم, و نظرا لان موضوع نقاط الجدارة كما اسلفت حضرتك يعتبر من افضل الاقسام يعني لا عذر لاي شخص في صعوبة الترقية في القسم العربي, 90% من المحتوى العربي يعتبر ثقني ومفيد وذو جودة عالية جدا وهدا من وجهة نظري هوا الاهم, العدد مهم بكل تأكيد ولكن يبقى المحتوى هوا الاهم بالنسبة لي.

مشكور.

Do you trust the seller's words like 100%? I hope you don't because I am pretty confident he is not telling you the truth, I have at least one the following gears.

T17
T17e
S17 pro
S17+

NONE of them would work without a voltage regulator and the voltage hardly dips below 190v, so even 195v was not enough, let alone 110-120v, so it's one of two things, either he is not telling you the truth, or he has gotten a magically different S17 pro that somehow manages to run on a 120v socket, and I highly doubt the latter, unless by "run" he means fans spinning, LEDs are on but not exactly hashing.

Even if the seller says it worked i wouldn't believe them, i have personal experience with these gears, anything below 200v it starts acting, maybe 198v and it shuts down all hash boards, i highly doubt his gear would be any different.

Your only option now is to plug it into a 200-240v socket and see how it does, it is a 50/50 chance i'd sat,it will either work just fine or you will need a new psu, it is highly unlikely that any other components got toasted in the process.

I consider this answer to be the most accurate, non of the above informations is wrong but they simply don't really answer the question (including my answer)

Lauda brought up a very interesting point to say the least, I have read about Poisson distribution in the white paper some time ago, but never thought of using exponential distribution to "estimate" time between blocks, after reading this I decided to make a little excel sheet.

Using the Cumulative distribution function for the exponential distribution where λ=1/600 as explained by Felix Weis




I am not completely new to probabilities and statistics, but after seeing these results I have to admit that I am surprised! I was not expecting to see such numbers.

Fun Facts:

- Every 621 blocks or 4.3 days one block is expected to take between 55-60 mins.

- 63.21% of blocks are solved in less than 10 mins.

- Every 4595 blocks or a month one block is expected to take 75 to 80 mins.

- Only 36.79% of blocks are actually solved in exactly 10 mins.

- Every 4.7 years a block can take 2 hours to be solved.


* Somebody might want to double-check these numbers.

Strange enough, the price keeps going up while diff is slowing down



1812 blocks down, 204 to go (34 hours estimated) to next adjustment, I expect us to close this round with +5% in terms of difficulty and coins at about flat $7400 or slightly below, with diff staying at 14.5T and coins prices above $7000 I expect a ton of gears to go back online, and the following diff adjustment could go to as high as 10%, in other words, back to difficulty's ATH.

Then go with the most efficient gear he has which is innosilicon T2T 30T if I am not mistaken, you need to do a bit of googling in terms of power consumption vs hash-rate, but by a quick look at the list you posted it seems like the T2T is the most efficient. Another reason why you should pick gear with higher hashrate is the shipping cost per TH, you mentioned $300 for shipping which sounds like a lot (maybe normal given the situation we are in now with the virus) but still getting fewer gears is better IMO, I wouldn't buy S9e, nobody reliable made a custom firmware for it, so not much tuning can be done on it, S9j is still better than S9e.

TL;DR

My vote goes to Inno T2T 30T

S9 can do as low as 75w per terahash after tweaking, so you could be looking at 700-750w for 9-10th, just about the same efficiency as the T2T, so I see the T2T as a better option here, but since you are willing to spend up to $700, why not get 1 proper gear that can actually make you some profit? like the T17 from Bitmain, or M21s from MicroBt? those have better efficiency, the T17 does 40th at about 2200w, so that can be both a learning experience and some profit, at worst case scenario you wouldn't be mining at a loss.

The other reason why I suggest buying newer gears is the fact that those old gears' design is over with, the S9 for an example, that was a beast that can bear all the heat and voltage instability, the newer gears are less robust and need to be treated gently, and I am pretty sure these gears get more sensitive as we move forward, remember how you could crack open almonds using Nokia phones?  . So really it's best to get used to these new gears rather than learning using an old gear that you will probably never deal with again.

بكل تأكيد من يتملك المال فقط يمكنه شراء الموقع, من يتملك المال فقط من يمكنه شراء اجهزة تعدين, ومن يتملك المال فقط يمكنه شراء بتكوين اصلا, ولكن القصة تكمن في "توزيع" تلك الاشياء, لو قام شخص مجهول لايمتلك اكبر منصة ولا يخطط لانشاء اكبر حوض تعدين لم يكن احد ليكثرث للامر, ولكن لان باينانس ليسو اشخاص عادين فعند وضع ايديهم على هده الاشياء يسبب قلق حتى وان كانت شكوكنا وقلقلنا ليس في محله,  حتى الان لاتوجد اي دعاوي لمقاطعة باينانس او موقع CMC, وانا اثفق معك تماما في كون اننا قادرين على محاربتهم في حال احتجنا الى ذلك, المشكلة تكمن في ان الحرب المتأخرة قد لاتأتي اي جدوى, ولكن خير مثال في شركة بتماين, فهم قامو بخداع الجميع واستعملو تقنية Overt-Asicboost لاشهر او لربما سنوات وكانو يكدبون الخبر, يقومون بتعدين بلوكز فارغة رغم الدعاوي المتكررة من المجتمع, يقومون بمعارضة Segwit بكل قوتهم, يمكنك قراءة التعليقات السلبية على حسابهم في المنتدى والاف الشكاوي ضدهم في المواقع الاخرى والامر وصل حتى لرفع دعاوي قضائية ضدهم في بعض الدول.

ومالنتيجة؟ بتماين تقوى كل يوم, وقد اطلقو احدث واقوى جهاز تعدين بتكوين في العالم وهوا S19 المبني على ثقنية 5 nano meter  التي لا تمتلكها الى شركات معدودة حول العالم, ياترا مالسبب وراء فشلنا في محاربة بتماين؟ لك ان تتخيل ان حتى الاشخاص الذين يحاربونها اصبحو بطريقة او باخرى مجبرين على شراء معدات التعدين منهم لانه في الكثير من الاحيان لايوجد غيرهم !!, مالسبب؟؟ السبب ان الشركة كبرت, سيطرت والان يصعب جدا محاربتها وعلينا ان ننتظر حظور منافس قوي لنتعاون مع للاطاح بها, او نستمتر في الحرب عليها بهده الطريقة حتى تغير مسارها.

لذلك من وجهة نظري الحرب ضد اي شخص يحاول فرض نفسه على المجال يجب ان تكون من اليوم الاول, تماما كما فعلنا مع CW عندما تظاهر بأنه ساتوشي لم يرحمه احد ولم يعطه احد الفرصة, الان نفس الشي يجب ان يطبق ضد باينانس قبل فوات الاوان.


اعتقد انهم سيقومون بمثل هده الاشياء, ولا اعتقد انهم سيخسرون عدد كبير من العملاء, مايهم العملاء هو عدم طلب KYC ووجود فوليوم عالي للتداول, انا كان العملاء يهتمون فعلا لكانو قاطعة باينانس بعد ابتزازها لعملة فريق DGB وتم فضحهم بالصور والدلائل وكييفة طلبهم اموال لادراج العملات بدلا من البحث عن الجودة, يوجد اتهامات ضدهم ايضا بعمليات بامب ودامب لعملات ICO وغيرها الكثير من الاشياء اللا اخلاقية, يمكنك القراءة عنها اكثر هنا https://twitter.com/jaredctate/status/1049706362408759296


انا لا اشكك في قدرة المجتمع على محاربة المركزية عند وجودها, ولكن تجاهل الموضوع عند بدايتها ينتج عنه الكثير من المشاكل في المستقبل, وكما نعامل الاعضاء الجدد هنا ونسبق الشك قبل الثقة, يجب ان نعامل المنصات الكبيرة والشخصيات المعروفة بالمثل. هده فقط وجهة نظري وربما اكون مخطاء, واتمنى في الواقع ان اكون مخطاء.

Keep in mind the "time" factor, taking a shower is 30-60 mins max, mining is 24/7, so the infrastructure might not be set up to handle the same load all that long, I also doubt the 10.5kw thing, are you sure about that? what kind of shower is that? I have a 200L water heater and a large pump and those combined don't go past 3kw, 10.5kw is enough for 2 average houses almost everywhere on planet earth, why would they allocate 10.5kw for an electric shower? 


With all due respect, I always talk about "Newbies" who mine at loss or break-even when we discuss future difficulty, sometimes based on the numbers in front of us, we expect diff to drop by say 10% and then it doesn't, or any other kind of speculations we do, those numbers are usually off because we miss a very critical element in the equation, which is miners like yourself, that is not a bad thing at all, I am just trying to tell you that "you are most certainly not alone in this", and I do encourage you to actually learn how to mine, and the best way of learning is by practicing it in real-life, mining for a week by yourself probably teaches you more about mining than reading half of the topics you find here, so mine on!


If you are located on the west side of Europe, then your best move would be finding a better power rate and not just more efficient gears, the word efficient gear is rather misunderstood, the word efficient is subjective really, as @Biffa mentioned that power costs about 16 cents in the UK, no gear will be efficient long enough and turn out to be profitable at such power rate, in other words, S15 is could be more "efficient" in China than S17 pro in the UK, when mining you are basically competing against everyone else, almost every competitor has access to the same mining gears so having more efficient gears than some other miners is not a huge advantage, however, having better power rate is the biggest advantage one can have against the world.

That's just what I think, it's not a popular or proven fact, it's simply how I interrupt the mining business based on my humble experience so take it with a grain of salt.

It is safe, no physical damage can be caused by the faulty dashboard, it might, however, cause the mine to restart every now and then which means financial damage.

I would still try to fix the board, I mean some time in the future another board will surely stop hashing, so it's good to have a spare, and your isn't completely dead since it shows all 63 basics at certain points, I suggest you try to play with the frequency and voltage in an attempt to get it to work, you can try one of the firmware I told you about or thierry4wd's suggestion, and then you can easily roll back to your desired firmware.

There is really no need for all that, line 463 in the kernel logs tells the whole story


Chain J8 ( most left ) is failing, in general, you can't do anything about it but watch it toast even more, soon enough it could start making the miner restart itself every now and then - and thus affecting the performance of the two working boards J6 and J7, however, there is hope and that would be by trying a different firmware such as BriianOs for Vnish (Asic.to / Awoesmeminer), and you want to play with the frequency of the bad board, start by going really low, test it for say 30 mins and then go higher slowly, sometimes increasing the voltage helps but keep that as your last resort.

if all the above fails, you should simply discount the bad board, and then separate the two boards, put on to the left and one to right (keep the middle empty) this way you ensure the boards get better cooling since the board in the middle usually runs hotter than the once on the sides.

First mistake:

You bought some shity gears for pretty high cost > don't let that bring you down to your knees, but next time maybe ask before buying anything?

So what do we have?

Volt: 240v
Wats: 2100*3 = 6300w or 26.5 amps , those need at least 35 amps mcb, I am not sure they make those, so you you might need a 40amp mcb, now for 40amp running on 240v you going to need a 6AWG cable.

That is based on the form below


Depending on what and what you are not allowed to do as far as wiring is concerned, you could simply run 6AWG copper wire from a single 40amp breaker to the sockets/miners or get 1*40amp mcm and 3*15amps breakers, each breaker is for a single miner

Wires from 40amp to 15amp is 6AWG and 12AWG from 15amp to miner, so you need a ensure your sockets can handle 2100w.


That will work too, but double-check the wirings you have, breakers are easy to change, wires are not.

Now, of course, I would advise you to hire a professional, but if you decide to do it your own you could have a look at some of my setups.



you can read more about it here

Keep in mind my setup could be bad enough to send me to jail if I was based in the U.S or any other similar country, it's perfect where I am located and done by the code   and it works for me.

As for the mining pool and all that, I wouldn't worry about it, get your wirings done, set up your gears and then start a different thread for that only.

Good luck.

الاعتقاد السأئد ان في الوحدة قوة والتفرق ضعف,  وهدا الاعتقاد منطقي الى حد كبير جدا, ولكن احيانا الواقع يكون عكس ذلك, عند وجود اتحاد بين طرفين يعتقد كل منهم ان الاخر محتاج له وهوا غير محتاج للطرف الاخر, يتنج عن ذلك التوحد مشاكل تقوم باضعاف الطرفين, فكا ان طلاق الزوجين يعتبر شي سيء في العادة الا انه في بعض الاحوال يصب في مصلحة الجميع, الزوج , الزوجة وحتى الابناء فلا فائدة من "اتحاد" لا يؤتي ثماره.

انا لست على دراية تامة بالوضع في اليمن, بالرغم من لدي اصدقاء يمنين خصوصا من الجنوب اليمني, ولكن مايظر لي ان اتحادهم يسبب لهم المشاكل وربما الانفصال هوا الحل للطرفين, وخير دليل على ان الانفصال لايعني الهزيمة هوا انفصال بريطانيا على الاتحاد الاوروبي, لا اعتقد ان الاولى تعتقد انها افضل من كل الدول التي انفصلت عنها, ولكن كما اسلفت احيانا الانفصال يكون انفع وافيد.

اتمنى ان يعم الامن في اليمن وسائر الدول العريبة.

الخوف هنا من المركزية،
، لماذا تسعى باينانس لشراء موقع cmc ؟

ان عرف السبب، بطل العجب.. انا مثفق معك في ان اداء الموقع ربما يميل للسيء ولكن هل تعتقد ان باينانس يهمهم الامر ويريدون فقط تطويره؟؟ لا اعتقد ذلك، على الارجح سيتم التلاعب بالبيانات لمصالح شخصية فهدا الموقع يعمل كمرجع للعملات ومن يملكه يمكنه فعل الكثير.

الشي الاخر هوا رغبة باينانس في اطلاق حوض تعدين والاجتماعات والاتصالات مع مزارع تعدين كبرى في الصين وحول العالم..باينانس تريد التواجد ف كل مجالات الكريبتو وهدا مؤشر سلبي بالنسبة لي...

تخيل انك تمتلك اكبر مرجع ... واكبر منصة..واكبر حوض تعدين !! اليس هدا مؤشر خطير بالنسبة للامركزية؟؟

انا اثق في باينانس كمنصة ولكن لا اثق في CZ ولا في طريقة ادارة الصينين اصلا..يمكنك البحث عن المشكلة التي حدث بين فريق عملة dgb وباينانس وكيف تم اتبزاز فريق dgb  لدفع الاموال مقابل ادراج عملتهم... وماذا كانت ردة فعل باينانس، سيتبين لك ان ادارة هده المنصة مهوسة بالتملك وربما تحاول فعليا السيطرة على المجال.

اعتقد ان الجميع يعلم انها كدبة ابريل ، الامر واضح ولا اعتقد ان اي شخص قد اندهش او خاف عند مشاهدة هده المزحة، ومع ذلك ان كان هناك اناس قد تفاجئو فعلا فهدا درس جيد لهم.. لايوجد استثمار مضمون في العالم، والبتكوين ليست معصومة من السقوط او الاختفاء، يعني مايبدو مزاحا الان يمكن ان يكون حقيقة في المستقبل..ان كنت لست مستعد لسيناريو مماثل من الافضل لك ان تكون

I don't think that is a possible scenario, bitmain owns two of the largest pools and they are from that 50%, they also manufacture most of the gears and do own a ton of them, in a nutshell 50% of hash power is way above binance's capabilities.

Keep in mind that miners can switch pools in a second, also it is for Binance's best interest to not try and do anything obviously damaging to bitcoin.


IIRC CZ didn't ask for a roll back, he talked about the pros and cons of it and i think he mentioned that roll backs are bad for bitcoin and he wouldn't want to see them happen, some digging into his Twitter needs to be done to confirm this.

I am with you in regards to having more "major" pools, if it was only a mining pool they are up to i would support that, but the CMC thing is what makes me worried about binance shady goals, there is also the incident with DGB where binance asked how much can dgb team afford to pay to be listed, all of those things make me not trust binance for anything outside of thier exchange which they have proved to be good at running it so far.

هل قمت بقراءة الموضوع اخي قبل ان تسئل السؤال؟ هدا الموقع لا يطلب اي اوراق لاتبات الهوية KYC عند شرائك لبطاقات فيزا افتراضية, لست على دراية بالمنتجات الاخرى التي بيعيونها.


قم بالبحث, وانتظر اجابة الاعضاء الاخرين فربما احدهم يعرف مواقع اخرى.

GUI = graphical user interface

In other words, you open your browser (Google Chrome for an example), and then you type the IP address of the miner (For an example 192.168.1.10, that opens the GUI of your miner.

from there you can see Miner status, Kernel logs and all the other information we need to see, the kernel log is a text which you copy and paste here, the status page and setting page you should take a screenshot, upload it to imgur.com and post the image URL here.

And honestly, if you can't do the above you shouldn't be mining.

هل تقصد green address?

اعتقد ان تلك المحفظة مبنية على multi-sig بنظام 2of2

مما يعني انك بحاجة لتوقيعان واحد تملكه انت والاخر تملكه المحفظة ..الخلاصة انه لايمكنك نقل اي شي من المحفظة باستخدام مفتاح خاص واحد..مما يعني ان فريق الدعم يحب ان يساعدك لحل هده المشكلة.. ثقنيا يمكن استرداد litecoin من عنوان بتكوين والعكس، عمليا الموضوع يعتمد على المحفظة.
