I appreciate you trying to help, but can you tell us where did you find this firmware? I am not accusing you of anything but given the fact that these weird miner models are probably  a modified bitmain/canan/Microbt it means that firmware from one of these manufactures will do that job (after knowing which hashboard the A1 uses).

Please don't get me wrong, but we have a dozen people trying to spread infected firmware on a daily bases, and it's my duty to notify you and whoever that plans on downloading the firmware of the fact it could very well be infected.

بالنظر الى Coinbase transaction لهدا العنوان https://blockchair.com/bitcoin/transaction/f38d6f043c070ce9805ee81f46db4d32d0c9f148d62bbfbc0378bc5847c7dc70
نجد انه اول تحويل كان في البلوك 3654 ان قمنا بتحويل هدا لمعادل زمني فنحصل على

3654\144 = 25 يوم

144= عدد البلوكز اليومية وذلك باعتماد ان كل بلوك ياخد في المتوسط 10 دقائق, 6 بلوكز في الساعة او 144 بلوك في اليوم.

يعني بعد مرور 25 يوم على اول بلوك, وهدا اول مؤشر على كون ان هدا العنوان قد لايكون لساتوشي لانه في تلك الفترة كان هناك عدد لابأس به من الناس الذين يجربون البتكوين, طبعا وبكل تأكيد هدا لاينفي مطلقا كون ان ساتوشي هوا صاحب هدا العنوان ولكنه مستبعد جدا, فنحن متأكدين من بعض العنواين التي يمتلكها ساتوشي والتي تحتوي مبالغ اكبر من هده بكثير والاجدر به ان يقوم باستعمال تلك العناوين, ونظرا لان ساتوشي قد اختفى وحاول اخفاء نفسه لمدة تقارب ال 10 سنوات, لا اعتقد انه سيتصرف مثل هدا التصرف الان خصوصا ان جميع العنواين القديمة تتم مراقبتها عن كتب سواء من الناس العادين او الاستخبارات.

You are saying if the price of gas goes up against fiat (USD) it won't go up against BTC because inflation takes everything against USD to the upside, right? if that's what you mean, sorry it's wrong.

That would only be true if the only commodity/currency in the world was BTC, but this is not the case, inflation of fiat doesn't automatically/magically give BTC any more direct value, and the simple proof is this exact period of time, how many trillions of fiat money was injected in the market post Covid19? is BTC making any higher highs on price? Nop it's doing the opposite, the money injected into the market simply did not find it's way into bitcoin.

Now to be honest, none of what you said nor what I have explained matters to begin with, simply because the host will sign a contract with gears' owners to be the hosting price in USD, if BTC goes 10 times up, and gas price increases only 50%, the host can't tell his clients, "oh you are now making way more money and I am losing money, pay me more", no such thing can happen, the host will be obligated to pay his power bill in fiat, and miners pay him in fiat, so if gas prices go up, he will handle the risk alone.


I am with you on most of the points you made, I think they are valid and I tend to agree with them, but let's be respectful to one another please, wndsnb is an old-timer and a very nice person, he could be in the wrong this time, but indeed his opinion is to be respect nonetheless.

That is not the case, look at the chart, half or more of the signals did not trigger the way you describe them, miners don't capitulate only if the price dips, the mining business is way more complex compared to the average HODL business, miners can capitulate on the way up or the sideways market just the same as they capitulate on bear markets, there is a ton of explainings and reasons on why these facts are valid, I know it's hard to understand that miners can capitulate even when the price is going up, but it happens and it has happened before, and there are solid reasons for why that happens.



I would have been surprised if you sided the herd into taking anything else but this, looking at the charts for so long and analyzing the fundamentals of the market makes you see things the average joe can't see, the correlations between hashrate and price in both directions is one of a lot of things traders observe.

Well, that and the fact that it's an (E) version, the chips they use on any E version are usually the lowest quality overclocked, they get hot and fail faster than the rest, despite my good experience "so far" with the T17E, reading and hearing from miners who own a dozen of the 17 series, almost all of them agree that the T17e is the worst gear with the highest failure/RMA rate, most commonly heatsinks/chips fall off the hashboard, I have almost reached to the conclusion that only the S17 pro version is actually worth buying, so S17e shipping (possibly) by end of July is a no for me, but good luck to those who will buy it.

ومن قال انه يوجد اي شخص في المنتدى يعطي نقاط الجدارة بناء على تفاعل الاعضاء مع الموضوع او المنشور؟ لا اعتقد ان اي شخص طبيعي ولديه بديهيات تقيم المنشورات وفهم حتى بسيط لفائدة ووظيفة نقاط الجدارة يتعامل مع نقاط الجدارة باي طريقة اخرى, ولك خير دليل في قسم العملات البديلة سواء في القسم العربي او الاجنبي فهيا الاكثر نشاطا والاكثر تفاعلا ولكن الاقل حصولا على نقاط الجدارة لان جودة المحتوى ضعيفة جدا.

طبعا هدا لايحل مشكلة ان كل عضو يقيم "التعب" و "قيمة" المشنور من منظوره الشخصي, لذلك قد تلاحظ ان بعض المنشاير تتحصل على نقطة واحدة وهدا راجع لان الشخص التي اعطا تلك النقطة يراه يستحق وغيره لا, او لانهم لم يشاهدو ذلك المنشور اصلا, اعتقد كونك عضو جديد لا داعي لان تقلق نفسك بموضوع نقاط الجدارة اساسا, فقط حاول الانخراط ونشر ماهو مفيد للاعضاء الاخرين وكل شي سوف يأتي لوحده ان شاء الله.

Sorry to have to be the one to tell you this, but you got all of these things confused, you don't know what you are doing.

GTX 1080 Ti alone makes nearly as much profit as antminer S9, your GPUs were not affected by the bitcoin halving by any means, the S9 was, another mistake you did was installing NH firmware, nicehash is a shady business, mining to their pool is already risky, let alone running their firmware, you should revert to the original firmware and can still mine to nicehash.

If you are using the custom firmware you should use


Using a custom firmware like Asic.to / Aweomse miner with Asicboost enabled you will have to use



Based on current difficulty and estimated block fees, S9 makes 0.000124 BTC a day, or 0.00002066BTC every 4 hours as opposed to the 0.00001692BTC you got, but 4 hours is not long enough to make any conclusion, however, the fact that your miner runs quietly indicates that the stupid NH firmware downclocked your miner and it's not hashing at full speed.

TL: DR

Flash the original firmware, use https://whattomine.com/ to estimate your S9 profit, do NOT compare it to anything else.

That is a good observation, do the frequency and voltage settings appear by default on the fixed-frequency firmware or you have to unlock them using the same method?

Would be nice to get a list of all 17 series mining gears that have a fixed-frequency firmware available by bitmain, also where to find them because they don't seem to be available on bitmain's website.

Well my opinion is that nobody would invest in a solar system of 20MW just to mine with a 286PH worth of hash rate, the cost of solar arrays alone would be about 3$ per watt, say he gets it for 2$ given the size of the system, so roughly 2 million dollars per MW, or 20M for the whole system, if he is going to go on-grid to not have to deal with batteries, he will need about a 5 times larger system, it just can't work.

This datacenter is a piece of art.

Reading into the article this is what they seem to have as far as BTC or SHA256 is concerned.


https://news.bitcoin.com/hyperblock-bitcoin-mining-servers-and-datacenter-infrastructure-to-be-auctioned-off-in-public-sale/



A translation of that to hash power we get:



That is a whooping 286PH of hash power, unfortunately, 32.3% of that hash power is close to useless now, the S9 and Avalon921 are far form efficient and they can hardly mine anything anymore (except in a few countries with free or almost free power rate), Ironically if these get picked by a re-seller - they will probably send those S9s back to China to get a good deal on them because in the U.S they are pretty worthless, good luck with the auction.

اعتقد ان الكثير منا قد وقعو في نفس الخطاء ولكن اعتقد ان اي انسان طبيعي كان سيفعل نفس الشي, المشكلة وانه حتى عند قرائنا لمثل هده القصص فنحن لا نتعلم منها, او بالاحرى لا نستفيد منها ونطبق, ولكن كل هده الاشياء تفوق قدراتنا البشرية, وانا شبه متأكد ان الاشخاص الذين لايزالون يحتفظون بالبتكوين طيلة هده السنوات هم عبارة عن

1- ناس نسو انهم يمتلكمون بتكوين وتذكرو في 2017 عند ارتفاع الاسعار وانشهار البتكوين والحديث عنها
2- ناس "ورثو" اشخاص اخرين من رواد البتكوين القدامى
3- ناس فقدو مفاتيح المحافظ وتحصلو عليها مؤخرا

ولا اعتقد ان اي شخص اشترى 1000 بتكوين بي 10$ وبائعها ب 10 مليون دولار بمحظ ارادته الناتجة عن الانتظار فهدا الامر سايكولوجيا غير ممكن للاشخاص الطبيعين على الاقل, تخيل الان انك تشتري 0.05$ ب 500$ وبعد سنتين يصل سعر البتكوين الى نص مليون دولار وتصبح تمتلك مايقارب ال 30 الف دولار من استتمار قدره 500$, من شبه المستحيل ان تمنع نفسك من البيع, وبعد 5 سنوات عندما يصبح السعر "جدلا" 5 مليون دولار, ستنظر الى الماضي وتتحسر وتلوم نفسك.

مررت بتجاريب حزينة جدا في الكريبتو, والكثير من خيارتي الاقتصادية في الماضي ( ان تكن كلها ) كانت خاطئة, ولكن انا على يقين ان كل شي يحدث لسبب, وانه عسى ان تكرهوا شئيأ وهو خير لكم.

اتمنى ان تجد صديقك الذي تبحت عنه, يوجد عضو باسم عمر هنا ولكنه مختفي من فترة, لا اعرف ان كان هوا نفسه او لا, وعلى العموم الكثير من القدامى تركو المنتدى لذلك يمكن ان يكون قد رحل, ومرحبا بك في المنتدى على كل حال.

Regardless of how he did it, he did try to help you, supporting people isn't always done by encouraging them to go ahead with their plans  .

I am not from the U.S but if whatever he mentioned in terms of tax and labor in NY then I would be giving you the exact same advice, mining isn't easy, I usually tell people to consider the fact the many people with access to a lot of money and FREE power don't mine, this is the reason why a few others who pay for power can still mine.

In your opinion, if it is all about power cost, wouldn't people with free power rate concur the network and kick you and everybody else out of the game? But because it is not, then that should get you think twice, just because you managed to find a cheap source for power it doesn't solve the other dozen issues.

We have seen multi-billion operations, Megawatts of mining gears lose their business and leave the game, so mining at it's basic form is already risky, let alone hosting gears you don't own and having to comply with all the contracts, risk, security, downtime, insurance, legal papers and etc.

You also still need to beat the average hosting price which is 5-6 cents per kwh IIRC, and will you be able to do that for a long period of time? Do you have enough capital for infrastructure and cooling?  How much would you pay for a person to be onsite 24/7 to handle reboots , mcb failures?

Ok let's assume you were allowed to do that, and you have a miner with 3 boards, placed this way

Chain0||Chain1||Chain2

chain2 has a working PCB temp sensor, Chain1, and Chain0 don't if Chain0 gets too hot, will the temp sensor on Chain2 be able to sensor that soon even before the meltdown? given the fact the temps reported by each sensor on the same board differ by a good margin, the temps on each board can differ even more, unless I am missing something, I still don't think it's safe to run in this way! please elaborate.

To me, even fan sensors are not required and can be disabled like most custom firmware offer simply because you might be using immersion cooling and also due to the fact that even if the fan fails nothing bad will happen, the miner temp become too high and the sensor will force the miner to stop hashing.

The PCB sensor is a MUST imo, at least 1 PCB sensor on every chain is a MUST, some people will say even 1 is not enough and at least 2 are needed(one in the front and one at the back ) but I think 1 PCB temp on each board is good enough.

I personally tend to believe that difficulty follows price at least, for the most part, I, however, don't completely negate the fact that at certain times the opposite is true, in fact, some respected, well-experienced miners and old-timers believe that at many times difficulty leads price, so with all due respect to some of these gentlemen who make it sound like you were trying to predict bitcoin price by multiplying the number of eggs in your fridge by the number of red socks your neighbor has, the correlation between difficulty and price is a lot more accurate than that.

One of the most (if not the most) accurate indicator on Tradingview has always been the hash ribbons indicator, it uses NOTHING but hashrate/difficulty to predict the next move with nearly 100% accuracy.



The reason why most people think this is not possible is again simply based on the lack of understanding of many things surrounding bitcoin and market cycles in general actually work, every market consists of a capitulation phase and since miners are the backbone of bitcoin, their capitulation means a lot to the price, remember the famous saying "the time to buy is when there's blood in the streets"? well, tracking difficulty could be a great way to time that.

I, however, don't think it's possible to predict price using difficulty neither opposite for a short period of time like you have demonstrated, looking at the average price of week 1 and expecting difficulty to be at x value in week 2 is not going to work, tracking larger samples like the hash ribbon indicator does is certainly an intelligent way of using difficulty to predict price.

You forgot to mention something!

1miau : "Received 2 years of ass-kicking by Mikeywith merit wise"    just kidding.

Congrats bro, it has been a great two years, you are one in a million, you should be proud of yourself for all what you have achieved, you set a great example of how a member of Bitcointalk should be.

Not really, what if for whatever reason something blocks the fans like a piece of cloth/paper or whatever or a fan stops and its sensors don't respond, there are many reasons for a board to overheat even when underclocked, and without a temp sensor to shut down the miner the risk is too much to be taken given the tiny rewards, even if it was a miner that yields $100 a day, burning a whole house/farm for that is not the smartest thing to do.

4G has an avereage latency of 50ms, it's more than fine for mining purposes.


There is really no correlation between these two, where I live there are places without electricity infrastructure and yet the cellular signal is great, you could be living downtown and have a terrible signal, at worst case scenario he could get a cheap amplifier.


All he needs is a single GSM model with an ethernet port (most of them have it), then a wire from that GSM model to a switch/router then hardwire the miners from there, there is no extra cost in setting up a LAN over cellular as opposed to cable/ADSL/Wimax, the same basic equipment is needed in the inside.

$400-500 + the time wasted from sending it to receiving it back will probably cause you to lose more than you will ever mine with that gear, they do have an address in Netherlands, I presume it would be cheaper and faster to ship it there, you need to ask them if you can send it there (obviously after checking the shipping price to that location), here is a list of all their repair sites.

There is a confusion here which I am trying to clear, the antennas you are talking about are cellular signal boosters or PTP Wi-Fi (2.4 GHz and 5 GHz), what OP is asking about is the ku band satellite dishes up to 14 GHz, those can't be pointed to the tower (well they can, but there is nothing to communicate with there), on the other hand, the parabolic antennas can't be pointed to the geostationary satellite, so these two have completely different applications.


That's pretty cheap, especially if it includes a modem, and just in case for whatever reason he doesn't get a proper signal, he could use a signal amplifier like the one you explained about above.

Will the tower by any chance be tall enough to reach the orbit? I bet not, then he can't do such thing, there is no short cut, in internet over satellite, the dish must be pointed to the geostationary satellite which is located in the orbit.

If you are talking about CPE/AP used for PTP communications, then that also won't work that way, even if there was a tower nearby you won't be able to connect to it unless that tower has the required equipment and then whoever owns it must allow you to access it, think of these dishes, satellites and CPEs is a way of replacing the Lan/ethernet cable, so instead of running a cable 20,000 miles to orbit it gets replaced by a dish or running a cable for 1 mile at your farm or summer house because the pool (I mean swiming pool not mining pool, miners probably can't think of any pool but the mining once ) is too far from the router - you use CPEs for that, but that doesn't give you the ability to point any of those at any tower and then receive an internet connection.


Well that's going to be perfect for him, any clue about prices? I think it all comes down to these data plan prices, if he has 1-5 miners only, he might not fully utilize the unlimited quota, if he has 100-200 gears, then that would most likely be better, but there is no way for us to answer this until we know the prices of those plans and the number of gears he is planning to run.
