Great stuff, this is actually how to Sdcard flash pretty much all miners, so you might want to change the subject for better SEO optimization.

The only difference is that the new models like the 17 series and even the K and SE versions of S9 is that there is no jumper to be changed, the control boards are made in away so that when they sense an Sdcard in the slot - they use it to flash the files on the card instead of booting the installed firmware.

But wait, why did you have to go this route? did HiveOn lock your miner? as far as I know all custom firmware are not locked and you can easily go back to stock firmware, but if Hiveon does that then they probably deserve a negative feedback on their profile until they solve this issue.


This isn't exactly correct, you can pretty much do with any size, Bitmain recommend 16GB or less, I know it will work with large SDcards too, the smaller the better but if you have no options, work with whatever you have available.

Thanks for sharing this great content.

I can go into detail on what needs fixing and how to troubleshoot the chips even further, but I have done that so many times in the past and it's all available on the forum, also this gear is so old that it isn't really worth fixing IMO, but it would be a great start for you to get things going.


I had a lot of brand new gears that arrived DOA, they didn't work out of the box, this isn't used vs new, it simply is Bitmain.


I wouldn't call myself a professional and I can't speak for others, but I have personally had a truckload of bad miners that needed fixing and troubleshooting, sending the gears back to Bitmain was not an option so every gear I bought (either to mine with or resell) I had to fix it or send it to the garbage, so the need for learning was very strong.

Also I would say at least 80% of the content related to mining gears comes from this very forum, we have a good number of great contributors whom I learned a lot from, I am also very active across all different mining groups from FB to Telegram and have many friends who own a lot of mining gears, mining is LIFE for me.

With that being said, rest assured that troubleshooting mining gears require no skills, you just need to go through a ton of issue and these issues kind of repeat themselves every step of the way, one last thing worth mentioning is that Bitmain gears are "crazy", you might turn on the miner tomorrow and it hashes at full speed showing all asics as if there was never a problem.  

Good luck and please keep us updated.

Since this is a proposal for a community project, then this particular point does matter, mind explaining how PPS is a net negative for BTC?

I do understand that you as someone who owns a PPLNS pool could be biased but that doesn't change the fact that your inputs are highly valuable.

The way I see it is that the investors/bondholders will have a very low-risk investment, I also don't think it's mandatory to have pre-hash contracts before you launch, I think it all boils down to the fact that the hashrate is irrelevant as long as the reserves of the pool are large enough to keep a low probability of bankruptcy, we have living proofs of small PPS pools such as Sigmapool.

Also, another factor that this whole idea revolves around the fact that this pool is going to be owned and operated by the Bitcointalk community, maybe my hopes are set too high but I am pretty confident that everyone who cares about bitcoin would pick this pool over Bitmain's or any other large cooperation's pool ESPECIALLY when they have to pay the same fees on both pools.


3% isn't better then everyone anymore, F2pool and BinancePool have 2.5% fees, which is very likely the bare minimum any pool can have to be sustainable long term which means the following reserves are needed to keep a 0.1% chance of going bankrupt.

(6.25  *ln 1000) / (2*0.025) = 863.46 BTC

The results are pretty different, which means you were likely using an invalid worker/URL, however, you now have a bigger problem than just a trailing space or bad pool connection.


If I recall correctly the T9+ has 54 Asic on each dashboard, the exact number doesn't matter as I am 100% sure it's way more than 18, which means you have 3 faulty hash boards, and fixing them would cost more than what miner is actually worth.

Having said that, this could be a PSU related issue, try to unplug 2 hash boards and keep only 1, perform this test 3 times on each chain, I would also Sdcard the miner and install a custom firmware like Braiins or Vnish, sometimes a custom firmware that uses a different frequency and voltage can get the hash boards to work.

Doesn't that depend on the tax system? I mean you already pay 25% upfront when you import mining gears to the U.S, so even your gears turn out to be unprofitable 2 months later, you have simply lost 25%.

Another advantage of buying Bitcoin over mining is that Bitcoin doesn't become obsolete or defective, mining is a very high risk, your whole farm can catch fire, it has operational costs, security, maintenance, downtime, theft, etc.

Also, mining profit is a "taxable event", the moment you get those sweet payouts in your wallet, whatever amount you received is taxed based on the fiat value of the time the pool sent you the payouts, also once you sell your mined bitcoins you are taxed again, but when you buy bitcoin with USD you are not taxed until you sell, and if you sell at a loss you could use "tax-loss harvesting". Correct me if I am wrong.

I don't know enough about U.S taxes, I just read about recently in an attempt to figure out the U.S election effects on Bitcoins and how different tax rules could be applied.

As far as we know Bitmain hasn't shipped anything in a while, how are new gears being installed this weekend? whatever is in the article is actually based on their previous july article, there is no proof that they received those S19s, perhaps they only received the M31s+ from MicroBT.


The market cap of this stock is just about 100M, so that's just about 10M increase which is really NOTHING, almost all crypto coins including the shittiest once made much more than that the past week but coindesk.com has to write about it because they need content to keep the profit comning.

I also don't understand why would anyone invest in a company that is about to spend 25% of it's value on expensive mining gears that need above 18 months to ROI (a terrible business model as far a mining i concerned) unless they are counting on a massive bull market for Bitcoin and in the case, isn't buying BTC directly a better bet?

Back to difficulty.


we are 54 blocks ahead, BTC is making it's 3rd attempt to break the 12k level (very likely to break it and move to 14k), at current prices and difficulty S9 makes profit at 5 cents/kWh and less

5 cents = $0.35 per day
4 cents = $0.60 per day
3 cents = $0.90 per day

I think most of the fresh hashrate came from those old S9s.

نعم بكل تأكيد اخي فانتقادي لم يكن ضد المحفظة لان الكتريوم غنية للتعريف وكلامي عنها بالخير او الشر لن يغير شي, اعتراضي هوا على جميع المحافظ التي يتم استخادمها على نظام وندوز, خصوصا مع وجود بدائل بنفس الامكانيات ان لم تكن افضل (ببدائل اقصد بدائل لوندوز)


هده المشكلة لان فريق المحفظة يبدو انه مركز على محفظة الوندوز فقط وتم اهمال محفظة الهاتف فهيا ركيكة جدا وانا لم تعجبني بكل صراحة, طبعا لتخزين العملات على المدى الطويل يفضل استخدام hardware wallet , اما المبالغ الصغيرة ففي النهاية ان كنت مرتاح مع نظام وندوز فبكل تأكيد احد افضل الخيارات هوا محفظة اليكتروم, بالنسبة لي محفظة الاستعمال اليومي ايضا مهمة وانا لست مستعد لوضعها على نظام وندوز, طبعا انا لدي فوبيا من الاختراق والسرقة لدرجة اني احيانا اصنف نفسي "مريض نفسي" لذلك ربما خوفي من محافظ نظام وندوز مبالغ فيه ولايجب الاخد بكلامي بهدا الخصوص.

There might be an issue with how you use the pool/worker details, Antpool is the worst pool to test a miner with, I usually test cksolo as you can't make any mistakes as long as you use a valid BTC address, so please try the following:

URL:


Worker:


Password:


Allow up to 15 mins before you reboot the miner, if it starts mining then you know your issue was Antpool, if the problem remains, then I would like to see a screenshot of the miner status page and the system view (main page).

While privacy is indeed a huge concern especially when it has to do with the camera, those who need the job can still be anonymous, the system needs to run in a way that there are no links at all between whatever the 3rd party collects and the person's personal/public data, in other words, no connection between the member identity in your club and their identity on this forum for an example.

It's pretty useless to have a video of someone sitting in front of their PC when you don't know that person, but if somehow it was linked to their social media or bitcointalk account then that will be an issue.

Also, there is a major issue with the way you plan to operate, you are going to pay the members just for being online, which means there is a possibility that the system fails to send a task for a whole hour or two and then you simply need to pay them for that even if they haven't done anything, the question is, where will the money come from?

The payment model is somehow unfair, it's to everybody's interest not to receive any tasks, so those who get more tasks will be paid an equal amount to those who were somehow lucky and went away with jut 1-2 tasks, also the type of the tasks is important.

How about you don't pay them per hour and simply pay them by the tasks that are equivalent to your pay rate? if you are willing to pay $1 an hour, and your tasks cost 10 cents each, give them 10 tasks within an hour, if there are more tasks they make more money if there are fewer tasks then the money doesn't have to "come from nowhere".

Now if you are looking for people who have a bit of skill and are into crypto for the tech, then chances are this isn't going to work, but if you are just looking for people then it's almost guaranteed that even a low pay rate like that will attract a large number of people despite the privacy aspect.



 

Any other altenriatves? I can't seem to find anything similar to this locally, will something like this Conductive-Silicone-Adhesive-Compound work?

Also after a lot of research in this forum I found this post and ccgllc mentioned about using this product https://www.amazon.com/gp/product/B00HTV1TXA/ which is very similar to the Arctic Silve you suggested but a lot cheaper, unfouctnally I couldn't find that either.

Also in regards to buying the black glue from China, I was informed by zeus staff that it can't be out of the fridge for more than 10 days, so anyone thinking about buying that form China should be aware of this, if the shipping duration is 10 days or above, you shouldn't buy it from China.

اذا من منطلق الكود فالفكرة نفسها, السيطرة على الكود لا تعني شي وتغير الكود لايعني شي فالامر راجع لل full nodes في نهاية المطاف, وهدا الشي ينطبق على جميع العملات بدون استتناء سواء كانت عملة مبنية على Proof of Work او غيرها من الانظمة, وهده هي فكرة البلوك تشين اساسا, لايمكن لان يتملك شخص واحد او مجموعة صغيرة الكلمة العلية في القرارات المتعلقة بالعملة, ولهدا لا اعرف السبب وراء الهجوم على Bitcoin من هده الناحية.

الان بالعودة الى ديكرد, ان كان القرار النهائي في اختيار اي بلوك تشين يتم اتباعه للعقد اذا مافائدة التعدين و proof of work? في حال سيطر شخص ما على 51% من العملة يمكنه استخدام ماينر واحد لانشاء بلوك تشين خاص به والتصويت عليه؟ ان كانت الاجابة نعم يعني انه لافائدة من POW في حماية الشبكة من هجوم 51%, وان كانت الاجابة لا يعني انه لافائدة من العقد في الحماية ضد هجوم 51%, لا يمكن ان يتم تأمين الهجوم على نطاقين مختلفين, الا ان كان هناك جزء من النص مفقود واتمنى شرحه من قبلك.

It's doable, but I wouldn't say applicable for all old miners, the miner firmware needs to be customizable because almost all stock firmware on all different mining gears restrict the frequency and voltage you can use, at best they will give you a few options to select from like "Low-Power-Mode" or a set of fixed frequencies to chose from.

With that being said, the S9 is an exception (T9 as well since they use the same control board) using a custom firmware wether it's Braiin's or Vnish (the former is open-source and free) gives you the ability to downclock the S9s to a very low specs and that will make it run somehow quite and power efficient, however not to the extent where you can place it next to your bed, but with a few physical modifications you can reduce the noise significantly, you should check this topic.

Too late, it isn't feasible in my case anyway, "exporting" these kind of stuff isn't easy and most certainly not worth the efforts, thanks for the info anyway.

Mind sharing your electricity cost? and can you host old gen miners? let me know we might work something out.


sea freight or at least this is how we do it here, shipping old gears using air freight is very costly, imagine you buy an S9 for 40$ and have to pay about  $80-100 for shipping? using sea freight we pay per cubic meter and pay about $200 per cubic meter, 1 cubic meter can safely take 30 miners + 30 PSUs so that' 200/30 = 6.6$ as opposed to $80-100 per miner, and it's 2 months vs 2 weeks.

Thanks for your input, but please bear with me here because I can't seem to understand the "logic" behind the risk you talked about, as far as I know, the only way for the investor to lose money is IF the pool goes bankrupt if the pool doesn't do well or fails to attract miners the only loss is the operational cost.

Remember that these bonds are not interest-based but rather Zero-Coupon Bonds where bondholders don't get any interest for their bonds, and given enough funds to cover the reserve of keeping chances of bankruptcy at 0.01% to the investor it's a very low risk.

The only real problem I can see is not having enough hahrate to find blocks on regular bases, of course, this means you need to pay less to miners but let's assume your hahrate is too small that you have to pay 1 btc per day and yet don't find blocks for a whole year whereby you have already spent 365 btc, also the fact that miners have no motive to stick to the pool should they find another can make things worse.

An example:

You have 3 miners and their hashrate is subject to find a block in 30 days (at 100% luck), so you pay them (block/30) - fees for say 29 days at current numbers it's (6.25/30) 2.5% fees = 0.203125 BTC daily or 5.89 BTC paid for 29 days, and before the pool hits a block, those guys are gone and you have simply lost 5.89 BTC.

ان تركنا موضوع ال Fees جانبا باعتبار ان اي محفظة جيدة يجب ان تعطي كافة الصلاحيات للمستخدم, تبقى محفظة الكتروم في اسفل القائمة بالنسبة لي, نظرا لاني مقتنع شبه قناعة تامة ان نظام ويندوز لا يمتلك خصائص الامان الازمة لاستعياب محفظة بتكوين, وللاسف فأن محفظة الكتريوم على الاندرويد ضعيفة جدا ولايبدو ان المطورين يهتمون بها, ونظرا لان نظام IOS واندرويد اامن بكثير من نظام وندوز فأنا افضل محافظ الموبايل على محافظ ال PC حتى للاستعمال اليومي, لذلك ربما حان الوقت اخي يحى لكي تتعمق في محافظ الموبايل وانا شخصيا استعمل Coinomi وهي محفظة اكثر من رائعة باستتناء انها ليست مفتوحة المصدر.

I sent a PM to Theymos asking if he would be interested in using the forum funds to fund a PPS pool that is owned and operated by the community as sort of more decentralization to the mining side of Bitcoin.

My thoughts are that by next halving all small non-PPS pools would be gone, the profit margin in the mining industry is getting smaller and smaller every day and it's only a matter of time till we end up with 2-3 major pools which is a bit of concern.

Theymos did seem interested in the idea but from what I understood the forum funds aren't large enough to run a PPS pool at reasonable "very low risk" according to Meni Rosenfeld's formula.

What Theymos suggested was:


There a few mathematical errors in this but the idea seem interesting and I do like it.

The main issues about running anything catastrophe bond-related is that the bondholders need:

1- Assurance that the whole thing is not a scam:

Bitcointalk.org has been the center of the bitcoin evolution, it won't be hard for the community to come up with a perfect business model to attract investors, it isn't easy by any means but it could be done.

2- Very low-risk bonds since the rewards are also pretty low:

The different bond ratings solve the issue.

3- A well-maintained project.

The bitcointalk community does have some very smart devs who can probably maintain and operate a large scale pool, the two names I can think of are -ck and Kano as pool operators, although it's near impossible to get these two to work together, I guess we could figure something out.

* I have spoken about this with Phill, he has some interesting thoughts which I didn't quote here just in case he wants them to be private, so I hope him and everyone else can chime in with some thoughts on the project, and whether you think this business model could work or not, and of course, why and why not.

اعتقد عند الضغط على السهم الصغير الموجود تحت Fees ستتمكن من ادخال العمولة يدويا او على الاقل هدا ماجاء في موقعهم

https://support.blockchain.com/hc/en-us/articles/360000939883-Explaining-bitcoin-transaction-fees

يمكنك الاستعانة بهدا الموقع https://bitcoinfees.earn.com/ لتحديد كم تضع sats per byte , ايضا ان كنت لست مستعجل على الارسال يمكنك اختيار الحد الادنى وهوا 1sat per byte والتحويل قد يأخد  اسبوع او اكثر ولكنه في النهاية سيصل شبه مجانا.

يمكنك ايضا ان تعمل import لل seeds في محفظة اخرى ولكن لايمكنك نقل البتكوين من عنوان لاخر بدون دفع رسوم التعدين وحتى ان نقلتها بطريقة المذكورة ستكون هده القيمة في output مختلفة وارسالها سيكون مكلف بنفس الطريقة لذلك افضل حل ان تقوم بارسالها بعمولة صغيرة وايضا حاول استخدام محفظة تدعم Native Segwit فالتحويل من تلك العنواين ارخص بكثير.

That's a good point but the plaintext in these files is not separated by a comma, will that still work in all csv viewers? Excel does recognize it as a file that has eliminated data in it, it also gives you the option of "My data has headers".

Here is how the .txt file looks by default:



Here is how it looks after importing it to excel and exporting it as .csv




Simply changing the extension from .txt to .csv didn't change the way the data is represented in Notepad, so I am not sure different programs deal with this stuff.

Won't it be better to test lower values since it's pretty hot there? Anway I would recommend that thierry4d tries to implement an auto-downclock function for when a miner gets pretty hot (temps should be pre-set by the user), and vice-versa for when it's too cool, these should be optional features and not set by default.

I would also suggest you stick to 100% fans, these gears break easily as you are probably aware of by now, so you want them to run as cool as possible, and according to my experience, 25% which is about 1500 RPMs across all 4 fans makes the miner run a lot cooler.

Been there, done that. Trust me unless your searching skill is way better mine then LoyceV's blockdata will be your best source, alternatively, you can download the "Blockchair Database Dumps" from blockchair, but if you don't have a script/bot to do that for you, then you will need to manually download 10 years worth of DAILY data, assuming we never had a whole day without finding a block then you are going to download about 3650 files, so I suggest you stick to the former option.

Keep in mind that LoyceV has that data in a .txt file, so for you to convert it to CSV you going to need a workaround, and the easiest one would be using MS Excel.
