اقل سعر للبتكوين في تلك الفترة كان يوم 12 مارس 2020 وهدا كان في بداية  فايروس كارونا



في المقابل انضر الى تشارت الوباء


الوضع كان يتجه للاسواء وكل الاخبار كانت سلبية والاخبار كلها تحوم الوفيات وانهيار اقتصاد دول وكان الناس يهرعون لشراء المواد الغدائية, كل الاخبار كانت سلبية بالنسبة للكريبتو وبينما كان عوام البشر يبيعون اسهمهم وعملاتهم خوفا من المستقبل المضلم التي رسمه لهم الاعلام وبينما كانو منشغلون في شراء الكحول والطعام بدائت رؤوس الامول تتجه لشراء الاسهم والبتكوين باسعار مخفضة بعد ان قام عوام البشر بالتفريط فها.

في المقابل استمرت الاسعار بالصعود بكل هدوء حتى اندلعت موجة تويتات الون ماسك, وضهور فقاعة ال metaverse وكيف غيرت شركة فيسبوك اسمها لميتا , وخرجت علينا مئات العملات المتعلقة بها, حيت وصلت عمولة شراء من ميتا ماسك في بعض الاحيان لاكتر من 1000$, كل الاخبار في وقتها كانت موجبة (tesla, el-salvador , efts, elon musk, نجاح اللقاحات, عودة الانفتاح للكتير من الدول) البتكوين يقترب من 70 الف وفي طريقه لل 100 الف, وبعدها كلنا نعلم ماحدث.


في المقابل, واتناء هدا الموثتمر والاخبار الاجابية حول المفاوضات الروسية الاكرانية والبدء فعليا في استخدام العديد من انواع الطاقة النظيفة في امريكيا لتعدين البتكوين, دخول intel في عالم تعدين البتكوين, في ظل كل هده الاخبار الجيدة لايمكن للبتكوين ان يصعد بل العكس تماما, وهدا فعلا ماشهدناه في هده الايام فالاسعار انهارت من 47 الف دولار الى 39 الف عند كتابتي لهدا المنشور.

لذلك ومن وجهة نظري وتجربتي في هدا المجال فأن افضل وقت لشراء الكريبتو هوا مباشرة بعد الاخبار السلبية, حيث يحدث انهيار سريع للسعر ويخرج عوام الناس, هنا تكون فرصة للشراء وليس اتناء تداول الاخبار الاجابية.

Simply put, miners take the previous block's hash and add a nonce to it in an attempt to get a hash that is less than the current difficulty (has a certain number of leading zeros), here is a very simple example.

let's assume the previous hash is (11) and the miner is attempting a hash that starts with 0

if you hash 11 on it's own you get


you can use this website for testing > https://emn178.github.io/online-tools/sha256.html

so now I'll keep trying different values along side 11 to get a hash that starts with one 0

if I try 11f, I get


if I try 11f1


if I try 11f11


I kept trying all the way till I got to


and that gave me this hash which should solve a block


because this is just 1 zero, it was very easy for me to do it manually in just about 20 hahses, now if you try to get a hash that starts with two 0 zeros - it will take a lot longer, 5 zeros will be even worse and so on so forth.

Of course, the value of the hash includes many other things besides the prev block hash, but this is just me oversimplifying the matter.


To feasibility mine bitcoin you need to have a good share of the total hashrate, so anything below EH worth means a somehow large fluctuation, you won't be making more money mining solo (except the pool fees), so it's not worth the fluctuation IMO.


with 100% luck, you need 15 days to hit a block, so you could do so in 15 days, maybe 15 hours, and maybe 3 months, the question you should be asking yourself is "if I get an unlucky year whereby I only hit half the blocks I thought I would, can I survive?"

of course, if you measure this against infinity, it will be no different.


It will depend on your power rate and the efficiency of your miners, 100ph= 10000th, if you use something like S19 with 30w/th, it means a total of 30*10000/1000=300Kwh, or  7,200Kwh daily, if you pay 10 cents per KwH you will pay $720 daily, if you mine with S9s at 90w/th, you will pay 2,160 daily.

And with no offense to you, mining far with the same of 100PH will need at least 2 million dollars investment and a ton of planning.







 

I can't vouch for this product in particular, but I know someone has manufactured a "generic S19 95TH" and is selling it for $68 per TH, according to them, it's just an exact clone of the S19 with the same components but I can't recall the brand name they gave it, so it could be this one.

كون ان البتكوين غير معترف بها كعملة رسمية لا يعني انه يوجد قانون يمنع امتلاكها, وهدا هوا الحال في 99% من الدول باستتناء السلفادور(وربما دولة او دولتين اخرتين لا اعلمهم).

بالمجمل انا لا احب سماع الاخبار الايجابية المتعلقة بالبتكوين, واعتقد انها دائما بداية لانهيار الاسعار, فكما يعلم الجميع ان هدا السوق هوا مستقنع للتلاعب بالمستتمرين الجدد, فكلما زادت الاخبار الجيدة زادت رغبة الناس العادية في شراء البتكوين, وهدا يخلق مرحلة تصريف لما يعرف بالحيتان يقومون فها ببيع عملاتهم التي اشتروها بنصف او ربع السعر, ولو قمنا بربط الاحدات المتعلقة بالاخبار والسعر منذ 2017 سنجد انه في نهاية ذلك العام كانت الاخبار اجابية وكان من المفترض صدور ETF للبتكوين وكانت الاخبار كلها اجابية وبداء الناس يسرعون لشراء البتكوين وقام الحيتان بتصريفها لهم وانهارت الاسعار.

في المقابل في عام 2019 في ذروة ازمة فايروس كارونة حيت كانت كل الاخبار سلبية استمر السعر في الصعود ليصل مستويات قاربت ال 70 الف دولار, في ذلك الوقت كانت الاخبار تحوم حول قبول تسلا للبتكوين, وقامت السلفادور بتبني العملة كعملة رسمية وكانت الاخبار اكثرها مفرحة, ومن هناك انهارت الاسعار.

There is no such feature, you need to make your own, and it will cost you a LOT. You need to hire someone to write a piece of code that logs the miners' logs somewhere safe only you have access to, or that same person might be able to modify the firmware so that it locks the mining pool (like what most viruses do), you can also prevent them from installing a firmware by requiring a signature.

You can seal the sdcard holder so that you know if anyone touches it, because disabling the scard flash means you need to disable the bootloader on the control board, which means, you will lock everyone including yourself out of that miner and you will never be able to flash different firmware.

But if your guys have the time to flash a different firmware, mine to their wallet for a while, and then install a different firmware, all of that while using a Sdcard, then nobody can fix that on a software level, it will be a lot easier to hire someone else who watches over your employees.

This is also hard to fix on a network level (but a lot cheaper )because if they use the same mining pool you use, then nothing on the network side can be done, unless you use a mining proxy, and here is how I picture it.

A mining proxy sits on a PC that nobody but you has access to.
All miners mine to that proxy.
Your router's firewall is configured to drop every packet that isn't coming from or going to the IP address of the PC that has the proxy running.

This way even if they change the pool settings, the pool will be "dead" and the miner won't connect, they have to connect to the proxy, and since they don't have access to the proxy, the proxy will connect to your pool with your worker only.

of course, they can bypass all of this if they have access to the router, they can just bring their own router and bypass the firewall, so maybe put it in a safe? but really, if you are worried about physical intervention happening on your farm -- you need to hire better people or hire other people to watch those people over CCTVs (to ensure they don't change the router for anything like that)

With almost half the blocks in this epoch are yet to be mined, it's more likely than not that we end up with a +, also MicroBT are releasing their M50 beasts, the basic M50 does
114TH at 29w/th, while the S version does 126TH and consumes only 26w/th, orders for the general public will be in Q4 according to them, which means, some "lucky" folks have probably already gotten their hands on a few thousands of these mega miners.

I have access to hundreds of used Antminer S9i/S9j with Bitmian's PSU in Malaysia, the owner prefers large order quantities but is willing to discuss smaller orders.

The price of the miner + PSU is $200 to $250 depending on the quantity (Shipping is NOT included)



If you are interested, reach out via PM or post here.

Edit 1:
** MOQ is 100 pcs
** Personal pick-up and testing of miners in Malaysia is possible

What kind of software are you planning on writing? the mining field is pretty limited in that aspect, it's either a mining pool, a monitoring software, or firmware, none of these require having a large farm, just a few gears for testing, and a ton of coding skills and free time.

The other part would be the electrical and airflow design, you could learn a lot of things by trial and error when applying it to your own farm, but I am pretty sure a professional in those fields who knows nothing about mining will do a better a job.

With that said, if you really have the skills and time, then the best service you can offer would be miners repair, if you build the right team for it, you will make a lot of money, the only thing that is lacking in supply in all this mess are companies that can fix mining gears.

Q3 this year is just about accurate based on most articles I read, however, Intel is shipping out just the chips, the actual finished product is made by whoever gets their hands on those chips, kind of a long shot from here, but they will eventually get there and start making things even worse for the rest of us.


It's fairly easy to be ready for 80k BTC, it's not like we need to do anything in preparation for that event  , what we need to be prepared for however is a potential dip to 20k with difficulty rising on the other hand, I know these scenarios are unlikely to happen, but it's always a great idea to keep them in mind.

Great, mintrip seems like a trustworthy member here, also since you handed him the hash boards in person then at least we know for sure he is legit, the only thing left is whether he (alone or in a team) can actually fix these miners in a timely manner and as promised, and since I trust your judgment, I will leave it up to you, if you think I should include his service in the OP or wait for your review, just let me know.

Please fix your first post, add the kernel log inside a code tag.


The issue with the latest kernel you posted is in this line


This kind of error is very often caused by a dead hashboard, the S9SE and the S9k are terribly built, I had a 100% failure rate with them in no time, compared to S9, S9i, and S9j these gears are trash, so it's pretty normal to lose a hash board every now and then.

With that said, just to make sure that the issue is indeed with this chain and not something else -- do the following:

- Disconnect the other two working hash boards (unplug the power cables and ribbon/data cables)
- Use 3 of the disconnected PSU cables on Chain 0
- Use 1 of the disconnected ribbon cables on Chain 0
- Turn the miner on with only Chain 0 onboard

By doing this, you eliminate the majority of other issues that can cause this problem, if the hashboard still doesn't hash, then your last hope with be

1- Sdcard the miner back to an earlier firmware
2- Upgrade the miner to the latest firmware

Keep in mind that by doing the second one, you won't be able to roll back to the old firmware unless you use SDcard again.


If all of the above failed, you just have to disable the hahsboard by unplugging the hashboard's cables, keeping it plugged will slow the miner's boot.

1.2PH is TOO MUCH to gamble with, and yet TOO SMALL to win blocks at somehow consistent time intervals, it's most certainly a terrible idea to gamble with 240$ worth of Bitcoin every day unless you think gambling is good for you.

This of course changes if you had like 50PH and 1PH was just 2% of your hashrate and you want to play with it, just like how most of us here do, the majority of hashrate is pointed to a pool that would give us somehow a stable income, and a bit of the hashrate is pointed to solo pool merely for fun/gambling given the low chances.

The short answer is: It's a terrible idea.

This is called timing the market, if one can do it as perfectly as you describe it, they would be better off with just trading and not having to deal with all the mess associated with mining gears.

treating the gear as if you are holding that asset it mines is just a bad idea, when you invest in a mining gear it has to generate more of that given asset than you could otherwise buy with the cash you are willing to invest, or else, it's just a losing game, as it stands right now, most new gears have over 1 year ROI, thanks to the unlimited money supply the U.S investors have, they are throwing money at Bitmain and MicroBT and now Intel, like there is no tomorrow, some of them, will go broke that is for sure, but to many of them they don't play our rules, they recycle otherwise wasted energy and mine at a cost near zero, you are competing against those same people, so good luck.

I do NOT think the price is going to zero, my statement was:


The keyword here is "magically stop all miners" because it will be impossible to do so, 1 old PC sitting somewhere in the dark can maintain the network on its own,  the operation of mining does not need all the hashrate it has now, more hashrate does make bitcoin more secured but again even an old Nokia mobile can do the trick, so stoping all BTC mining operations isn't feasible, but if we were to 'hypothetically' assume it happened -- then nobody will be able to transact BTCbecause the transactions need to be put into blocks created by at least 1 miner, and thus, having bitcoin in your wallet will be no different than having 1 billion dollars in your wild dreams, none of these assets have any value in real life.

For this to make sense to you, you need to read about bitcoin mining and difficulty adjustment, once you fully understand that mining bitcoin can "at least" in theory be done with a pen and paper, you will understand that banning it completely is something beyond any government's ability.

اتوقع حدوث العكس تماما, بالنسبة لموضوع لأوروبا فكما ذكرت في السابق انها لاتمتل شي في تعدين البتكوين ونسبة التعدين هناك ضئيلة جدا فهي فعليا خارج اللعبة, اما بالنسبة لانظمام المزيد من الشركات لتعدين البتكوين فهدا امر يحصل حاليا, شركة بتماين وحدها قامت ببيع اجهزة تعدين بمئات الملاين لشركات ضخمة ضمن عقود لتسليمها كاملة مع نهاية عام 2023, ولايازال الطلب على اجهزة التعدين مستمر بطريقة جنونية.

العبرة هنا ليست في كمية البتكوين وانما القيمة بالدولار, عندما كان بلوك البتكوين ب 50 بتكوين كانت قيمةا البلوك كاملة لاتتجاوز ال 10 الاف دولار, اما الان وبالرغم من البلوك يحمل 6.25 بتكوين الا ان قيمتها حوالي الربع مليون دولار, السبب الاخر لزيادة رغبة الشركات الكبيرة بدخول التعدين هوا ان البتكوين قد نجح في اختبار "الوجود" واصبح امر واقع, والتعدين الان هوا أمن بكثير مما كان عليه منذ خمسة سنوات او عشرة سنوات.
,
الفرق بين التعدين اليوم والتعدين في الماضي هوا تغير طريقة اللعب, في الماضي عندما كان المعدنين الصغار يمثلون الاغلبية الساحقة, كان الموضوع سهل بالنسبة للاشخاص العادين, اما الان فاالمنافسة قائمة بين اصحاب رؤوس المال وشركات تمتلك مليارات الدولارات تود استتمارها, والفيصل في هدا الموضوع هوا

1- رأس المال
2- الطاقة الكهربائية الرخيصة

وهنا تتفوق الشركات الامريكية على غيرها, نظرا لسهولة الحصول على الاموال عبر تأسيس شركات تعدين وبيع اسهمها, والحصول على الطاقة هناك سهل جدا نظرا لوجود فائق هائل في الطاقة عندهم على عكس معظم الدول التي تعاني مشاكل في الطاقة, لذلك وحتى بعد انهيار سعر البتكوين بحوالي 50% في الاشهر الماضية, الهاش ريت لايزال في تصاعد مخيف حيت ان الشركات المصنعة تزود الشركات الامريكية بالالف الاجهزة الحديثة شهريا, ولا اتوقع ان يتوقف هدا النسق لسنوات.

Please use the code tag when posting the kernel logs.


The kernel log is incomplete, are you sure all PSUs cables are plugged in? also, what is the AC voltage at the input side of your PSU?

Mining rewards have little to no impact on the market now, let alone then, it's often thought that selling pressure from miners brings the price down or the opposite, but IMO that is far from correct, the mining rewards are just a fraction of the trading volume, the supply from "elsewhere" is A LOT greater than what miners get as mining rewards, and as more and more coins leave the hands of miners to non-miners, this little impact miners have over the market slowly diminishes until it becomes completely irrelevant.


As long as there is any sort of profit to be made "big or small" some miners will still run their gears, in fact, even if running mining gear results in a loss, many people will still mine just to keep the blockchain alive (self-interest for them to be able to send and receive bitcoin), but the bigger issue would be the blockchain's security.

if the incentives to run a mining gear don't exist -- the network becomes more prone to attacks, so bitcoin's security as it stands right now is closely related to its value, the more expensive it gets the more secured it becomes, hopefully, that will change one day when the majority of people start using and protecting bitcoin rather than just mining it for profit.

a 10 seconds latency in BTC mining is very costly since the mining pool won't be paying you money out of their own pocket, most pools will send new work within a few seconds and thus the majority of the shares you submit will be invalid, mining solo with such latency will also increase your stale block size by a large margin, but this idea is still applicable if the cost of setup and operation is a lot lower than mining on planet earth, although I highly doubt that this will be the case.

عدم دفع الضريبة يعني التهرب من الضرائب والتي تصل عقوبتها للسجن في معظم الدول, لذلك الحكومات تعتمد بالدرجة الاولى على خوف المواطنين من العقوبة, جميع معاملات الكاش لاتخضع للرقابة المالية واخفائها اسهل من اخفاء تحويل بتكوين, ولكن في حال تم امساكك متلبسا بالعواقب ستكون وخيمة لذلك اي شخص يخاف من القانون سوف يقووم بالتصريح عن اي تحويل متعلق بالبتكوين يقوم به.

اما عن وجهة نظري فأنا اتقف مع الاخ خالد, هده الخطوة سلبية اكتر من كونها اجابية, تأثيرها سلبي حتى على السعر, فهدا القانون سوف يسبب عزوف عن الشراء من المواطنين الهنود, نظرا لان تكلفة البتكوين ستكون اعلى ب 30%, سعر البتكوين الان هوا 45000$ باضافة ضريبة 30% تصبح التكلفة 58,500$, يعني اي شخص ينوي دفع الضريبة وعدم التهرب منها سوف يفكر خمسين مرة قبل شراء بتكوين بتكلفة اضافية بمثل هدا الحجم.

This is a general misconception regarding bitcoin mining, bitcoin mining can go on pretty smoothly with a block every 10 minutes even if one single old laptop or PC is mining it, so no matter what they do, they can not stop the supply.

BTC has limited supply either way, but if they were to magically stop all miners from mining forever, then BTC will not increase in price, it will go to zero as it will be pretty a useless technology, miners are needed to perform transactions not just to increase the supply.
