My thoughts exactly, this is why we should always prepare for all scenarios, I personally over-plan for the bear markets more than I do with the bull market, which is a mistake on my behalf that I don't seem to get rid of, so it creates "issues", but these are the kind of issues I love to face.


My plan is not to add in any more gears because of the current prices, I made a good/lucky move a few months ago and got my hands on cheap gears before this rally started, I did hit ROI on ALL of them, excluding those junky 17 series gears which many of them died in a very short period of time.

So the next step with be to mine and accumulate, and of course, sell a bit with every 3-5k up, so 34k, 37k, 42k, 55k and etc are all sell-targets all the way to infinity  , my logic behind this is that I want to be ready for the bear market, after being in this field for so long, I became so FOMO-resistant, it doesn't bother me if I sell and the price goes up, because I know that when it dips, I will be smiling big time.

So with enough cash collected from now until this bull cycle ends, I would sit back and relax and wait for the weak miners to sell their mining gears for dirt cheap, I did the same in 2018 (wrote a topic about it), I got me some mining gears at the bottom of the bear market, they were so cheap then, was probably my best move as far as mining is concerned, so ya, I plan to do the same thing again, not going to pay these high prices for mining gears while the average Joe is doing that, when I see people on mining groups on FB/telegram dying to get their hands on mining gears I know it's a bad time to be buying them, you don't buy mining gears right before difficulty spikes, it never works.

احسنت, هدا المقصود.



لن تتكرر محاولتك لانك سوف تقوم بداخل رقم او حرف جديد في كل محاولة, وهده اجابة على سؤالك التاني, لان طول الهاش لايوجد اي قوانين تحدده ( في هده المسابقة وهوا على خلاف الواقع) يعني انا لم اقل ان طول الهاش يجب ان يكون 4 خانات او 4000, يعني انت لست مجبر على التوقع, يمكن ان تكتب الف حرف واحد بعد الاخر, يمكن ايضا استعمال نفس الرقم يعني تكتب رقم 0 بدون توقف حتى تتحصل على الهاش, لو منعك الموقع من كتابة اكثر من الف 0 مثلا, يمكن بعد الانتهاء من الف صفر اضافة رقم 1 الى نهاية الهاش وبعدها كتابة الف 0 اخرين وسوف تكون النتائج مختلفة كليا, يوجد عدة طرق يمكنك ابتكارها لتتمكن من فعل هدا الشي في اسرع وقت ممكن.


نظرا لان شخص ما قد يكون وجد حل البلوك مسبقا فسوف اقوم بتغير الهاش, وسوف اقوم بتغير الصعوبة الى 000 بدلا من 0000, سوف اقوم بكتابة الهاش الجديد لاحقا, فقط انتظر من الاخوة الاخرين التأكيد بأنهم فهمو المطلوب حتى لايضيع احد وقته في حل بلوك خطاء.

I am a believer in bitcoin, I have always been, but I never stopped selling a good % of my mining earnings, you see the problem with mining is that it's very short-lived, it's not a long term business like most other businesses, mining gears either die or become obsolete in a couple of years at most, so every 1-3 years you need to "throw away" a ton of old gears and buy a new set of gears - this is not much different from starting a brand new business.

The above puts pressure on miners since every mining gear is a new short-term investment, miners rush to ROI the USD investment they put into it, and then you have another issue which is the "brutal bear", miners must always have a good amount of cash in order to be able to re-position themselves so that their mining operations don't come to a sudden end.

Every time the difficulty spikes or price drops, you have to act, you need to either buy more efficient gears to stay profitable or buy more of the same gears to justify the total operation cost, at one point you could have a huge farm that you spend $50 on gas to visit which only generates $100, it happens a lot and thus we try to stay liquid to act accordingly.

Some people might think that keeping BTC is as good as keeping cash as far as re-buying mining gear in a bear market is concerned, but this isn't true, mining gear pricing doesn't work this way.

The good thing is that miners are a small fish in a huge ocean as far as the market goes, the daily trading volume on a mediocre exchange is a couple of times higher than all of us miners can make.

That's good news, I am glad to hear that it was helpful, I knew it would be, just wasn't sure how detailed it is, but since I don't know much about electronics I had to hear it from someone who does.

I tried to copy-paste the text in Chinese to translate it but couldn't do that, can somebody with acrobat pro try it? would love to get the whole file translated to English.

I have seen a few members ask about this, and exactly zero resources are found on the internet as far as these PSUs are concerned, Zeusbtc released AWP9 / APW9+  repair guide which seems to come directly from Bitmain, it's in Mandarin but the pinout and many important details are in English, I am sure some miners will find this information useful, if there more details that you need you can get in touch with the support team at Zeusbtc.

I believe the S9 has a single PCB temp sensor which is TMP451, it seems like it's slightly hidden under the heatsinks, you could probably still see it without taking the heatsink off, according to a post in one of the Russian mining forums, pezhvak identified the temp sensor location in this post.



Image Source: forum.bits.media (I used a hyperlink because the URL is in russian and result in a very long string).

If the information provided in the post isn't accurate, please let me know, I can ask someone who probably knows.

I am 99% positive that it is a hardware issue, however, i would still test the miner with custom firmware since sometimes it could fix the issue, try vnish (asic.to or awesomeminer), chances are low but you have nothing to lose.

Looks like we are on the same boat for this epoch.  


I calculated the hashrate migration earlier on, looked into all SHA256 coins, and it seems like a little over 1EH migrated from those coins into BTC this epoch, so you are right, it's hardly 1%, but keep in mind 1EH is a truck full gears.

As it stands right now.


The current pace is 9.9% which just double what I initially predicted, . still, however, many things can happen in 7 days, and with bitcoin price at 33k, anything can happen.

This is the problem, Chain 1 shows only 40 asic when it's supposed to signal 48 chips, so there seem to be an issue with the 40th or 41th chip, usually, with these 17 series mining gears it's a loose heatsink that needs soldering.

With that being said, where is your chain 0 and chain 2, does this miner run with only 1 hashboard?

اعتقد ان جزء من المشكلة هوا وجود تصادم او تكرار في المحاولات بين الاعضاء, في اعتقادي ان الاغلبية يبد التجربة من ال 0 ويتجه تصاعديا ولهدا السبب لم نستفيد من تعدد المشاركين, لقد شرحت في منشور سابق عن مايعرف ب ExtraNonce وكيف تقوم الاحواض بتجنب تكرار نفس الارقام بين الماينرز, اعتقد انه ماكان يجب فعله من الاول هوا استعمال ال ExtraNonce حتى في هده المسابقة حيت يقوم كل مشترك باضافة اسمه في المنتدى الى الهاش مثلا الهاش الاخير بعد اضافة الرقم العشوائي من قبلي كان


يعني اقوم انا بالبحث عن هدا الهاش + اسم المستخدم الخاص بي والنتيجة تكون


مثلا الاخ خالد سيكون هاشه بهده الطريقة


بهده الطريقة نكون على يقين ان محاولات خالد ومحوالاتي لن تتكرر مهما حدث, يجب ان نتذكر ان المهم هوا عدد المحاولات ولايجب ان تكون تصاعديا, يعني فرصة ان تكون الاجابة بين رقم 0 و 10 هي نفسها في اي عشرة محاولات اخرى يعني حتى لو قمت بالظعط العشوائي على ازرار الكيبورد سوف تحصل على نفسة النتيجة, فقط تأكد من عدم تكرار نفس الادخال.


هل الامر واضح, ان كان كذلك ارجو اخباري كي اقوم بتعديل الصعوبة واعطائكم هاش جديد لنبداء به.

I don't think I can agree with this analogy, you see, your mechanic makes sense, if your car has a problem - it must be fixed, you can't ignore it, and delying it can only cause more harm, even if you were to sell the car without fixing it, it will be worth its price minus the fix.

On the other hand, the block size isn't really a problem, and even if it was a problem then delaying the fix works, in other words, the longer we stick to 1MB the less the size can get, and then eventually, the equipment needed to run a full node will become cheaper as we move forward, and the internet technology is going to improve (regardless of how fast that may happen).

Now back to why do I think the block size isn't a problem, people are still using bitcoin, they have not abandoned it, bitcoin still works just fine and has more transactions than most other coins combined.

What's even more important than all of this, is what do you expect from increasing the block size? most people I discussed this matter with think that when bitcoin becomes cheaper to transact, more people will use it, and adoption will go to the moon, but I don't see that happening for a few reasons.

1- Other coins with instant confirmation and almost zero fees are not being accepted everywhere and don't have a fraction of bitcoin adoption.
2- The main layer isn't suitable for micropayments and every day's transactions,  you are always subject to wait for hours until your transaction is confirmed, and if confirmation isn't important then people can still do with 1MB blocksize and pay the lowest fees possible.

There are many other reasons why blockchain as-is isn't fit to do the kind of things some people expect, increasing the block size could "solve" some "issues" but it can create worse issues.

يبدو ان صعوبة 0000 اكثر من قدرة المشتركين, كما ذكرت فأن متوسط المحاولات المطلوبة للحصول على 0000 هوا 65,536 , حسب تجربتي لحل الهاش يدوي اعتقد ان 3 هاشات في الثانية هوا معدل معقول جدا, يعني انه بالمجمل نحتاج الى 21,845 ثانية او 365 دقيقة او 6 ساعات لحل البلوك, لو كان هناك 6 اعضاء يتنافسون لحل هدا البلوك فسوف يكون متوسط زمن هدا البلوك هوا ساعة واحدة نظرا لان سرتعهم ستكون 18 هاش في الثانية.

وبكن يبدو انه لايوجد 6 اعضاء يحاولون حل هدا البلوك, وربما يكون شخص واحد يحاول ولم يجد الحل حتى الان, لذلك ماهو اقتراحكم هل نعيد الصعوبة الى 000 او 00؟ اما ماذا؟

It depends on what you can afford, but I'd say the average packages that the average can buy would be anywhere between 20GB to 30GB monthly quota and at a download speed of 1-2 Mbps and an upload of 0.2-0.4 Mbps.

Due to the nature of my job I can afford a 5Mbps up and 1Mbps down with above 100GB of quota and free download at certain periods, but I pay a little bit more than 20% of the average salary for a nurse, school teacher, or a police officers, but eventually when this package doesn't make economical sense (if I lose my job ), I will have to go back to those limited and slow packages.

And if you think that is bad, I have seen worse elsewhere.



There are at least a few countries where the average wage is below $50 a month, there are a few tens of other countries with monthly wages of below $200 and perhaps only 50 countries or so with wages of above $500 a month, so $200 is a lot of money for the majority of people given that most populated countries have low wages, it has been a while since I looked at the numbers but I can safely bet that at least 8 out of 10 human beings on this planet earth have wages that are below $300.

This isn't exactly bitcoin-related, but the majority of wealth sits in the hands of a minority of other people who are mainly located in EU and USA, it is just the way it is, and for those who can afford a full node with 5-10 hours of a moderate job, I do understand if you find it difficult to believe that others have to work for 2-3 months to afford an SSD that can accumulate the current blockchain size, and as hard as it is now, it will only get worse when the blocksize is increased.

With that being said, not all "poor" people will want to run a bitcoin node since even the current 300GB and the 1MB size is way too huge for them, but when we make suggestions of increasing block size to 16MB or lift the cap altogether, we have to evaluate the technology capabilities worldwide and not just within 5-10 developed countries, just my 2 bytes on the subject.

So we raise the block size to 8mb and then what do we do whenever that isn't enough? I am not against reducing or limiting the scaling problem by increasing block size but it doesn't really solve anything, no matter what you do, you can never beat the ordinary system in terms of speed and cost, blockchain is slow and expensive, this isn't exactly an issue it's more like some of its main characteristics, Paypal payments that are done on one server or a few at most will always outperform blockchain at its main layer, this isn't my opinion it's just how things are, saving a transaction on tens of thousands of computers isn't suppose to be faster and cheaper than visa or PayPal.


The second point which I feel the need to explain since you mentioned that you are from Germany which also goes to folks in the U.S and the other first-world countries, the internet is decades behind in most other places, where I live even with the current block size only a few people can run a full node or directly mine to their own node, 1MB of bandwidth is a big deal here, it's hard to believe because you just pay a fraction of your salary for a 100mbps or even 500mbps connection with unlimited quota, but elsewhere, you can hardly get a 1mbps line with very limited monthly quota, as it stands now, I can't even propagate a 1MB block in a timely manner. By increasing the block size you simply send many players out of the game.

Another point is the fact that your transaction will be saved on tens of thousands of computers and it would take years and billions of dollars to re-do the blockchain, it really has to come at a cost, getting your transaction on the blockchain is more secured than saving your money in the safety deposit boxes at your local bank, it is worth a lot, and someone has got to pay for it,  and at the end of the day, why would you want your 1$ transaction to be saved on the main layer?

One last thing, let's assume we solved the issue of block size, what about confirmation time? say the transaction fee is zero due to unlimited block size, will you be able to pay for coffee when relying only on the main layer? will the shop wait for 10 or 20 minutes until the transaction is confrimed before serving you coffee?

موضوع جيد وان مهتم بالتحليل الفني للعملات, ولكن كنت اتمنى ان تقوم بارفاق صور للتشارت كل تحليل تقوم به, الصور ابلغ من الكلام والشرح بدون صور فيما يتعلق بالتحليل الفني من الصعب فهمه جيدا, اتمنى ان تحذو حذو الاخ rep في موضوعه المشابه لموضوعك https://bitcointalk.org/index.php?topic=5115701.180.

بالتوفيق.

Almost all control boards of the 17/19 series that are bought separately from Bitmain (not with a mining gear) come with a firmware that says "Test Firmware" in bold red, which allows you to flash any other firmware, but the version they sent you could be a different one and it might be useful to some devs like thierry4wd and Marc, so could you please upload it and paste the link here?

The temps look fine to me as well, the fans seem to be spinning at about 50%, so unless it's freezing cold where you live - then all good.

Here is a sample of one of the S17 pros I have



Fans are set to 90% and ambient temperature is between 10-15c.

12.3% isn't realistic by any means, I doubt these numbers can be sustainable for the remaining 8-9 days of this epoch, the average hashrate for the past epoch was 133, so 12% of that is 16EH, how is it possible that a whooping 16EH came online now and not 10 days ago? but well, btc mining is crazy so you may never know!

With that being said, I still believe that we won't go past 5% by much, maybe 6-7% in the worst-case scenario, but not 12% or more, the reason why I tend to make my predictions a bit more flexible is that fact that BTC dominance is going higher and thus hashrate from other coins is migrating to bitcoin right now, so all the new hashrate we see now isn't exactly fresh hashrate, a good portion of it was already there, and when those other Sha256 coins start picking up, that hashrate will go back.

I don't see why they wouldn't, IIRC someone from the U.S said they ordered something from them, you can also check on Aliexpress, i believe it is the same product but a bit more expensive on Zeusbtc, but they have a good reputation and I have personally traded a lot with Kevin from Zeusbtc.

Then what was all that about


I do understand that Bitmain support is terrible, but this basic information that they should know, no? I would like to see what's in the master reset firmware they sent and if it's any different from that default-test firmware that comes with the separately purchased control board, jimjam123 can you upload the firmware they sent you?
