I responded to your PM.


The miners ship from Malaysia, however, I am sorry because 10 miners is below the MOQ assigned by the owner of those gears, initially, it was 300 miners, now I think it's possible to negation all the way down to 100, anything below that won't be possible. sorry again

Ok that makes sense, but you can't have an infinite loop, you will have to stop at one point, or else, everyone in the U.S would be mining bitcoin and you all would have been rich.

Also, a few key points are missing here, the most important being the lifespan of the miners you invest in, and that could be the physical status of the miner (dead before ROI) or it gets to the point where the power bill is a lot greater than it's projected income.

Also if I understand correctly, selling your mining gears later on for whatever reason is a taxable event, no? as well as selling your bitcoin to pay the power bill or to buy a new transformer or anything like that, even your received reward from the pool are taxable as income.

Phill's example above is a good one but there are a few things I don't get


So just to be clear here, and let's assume your business model isn't 50/50, and that you had to pay $$ every month for the power bills, that means, you would have to sell some coins (a taxable event) no?

The second question, your example also assumes that for all these years you did not spend a single dime and re-invested all of it in buying more miners, true?

furthermore, you now (according to the example) own 386k worth of mining gears, what happens when you sell them? you will pay a lump sum of tax?

and lastly, if you decided to stop expanding (which you will get to at one point), all the profit you make will be taxable even if you don't sell your bitcoin, and then if you sell it later on for higher a price that will be a capital gains tax, true?

Not that I could use any of these U.S tax tips, but it's an interesting topic, I would love for someone to give me a perfectly detailed example of all the tax involved with numbers.


Let's say today, You buy S19 for $10,000, for the next 12 months, it makes you $500 worth of coins monthly, every month you sell 100$ to pay the power bill, and use $100 to improve your mining farm to be able to add more capacity and $300 reinvested in mining gears, how much tax do you pay in total for the total mining profit you made per month?

Where did you get that 80% from? sorry but it makes no sense, looking at the coinbase of blocks which belong to that address you can see


So, clear as day that this address is owned by "Foundry USA Pool", now that we got that out of the way, let's examine the 80% you mentioned.

In the last 30 days, Foundry pool found 822 blocks, which is exactly 19% of the total 4,331 blocks the whole network found, so it's pretty safe to assume that they own on average 19% of all the hashrate.

Looking at today's results, Foundry found 27 blocks, which is 22% out of the 123 blocks the network found, that is 22%, which isn't far from the average 19%, it could be a bit of luck + more gears added to that pool, nothing unusual is happening here as far as I can see.


They have been the largest mining pool on planet earth for months.

Please use the code tag when posting such logs, something like this


it seems like your miner isn't reading the proper temps on all boards, did you try to flash the latest firmware?

PVT T0 shows the chip temperature on your hashboard no.0, so it could be an issue with that board, try to unplug it if there is a way and see if the miner works fine without, the Avalon A1246 seems to be of bad quality, at least this is what many people are reporting, most people say that Avalon's old models were way more solid than the new models, it's probably why the new models sell cheaper than Bitmaind and MicroBT.

Also, do update the full logs, a few people here know how to read the logs from Avalon and will probably provide you with more info.

Your miner's temps look perfectly fine to me, however, your fan readings don't make sense to me, I don't think Bitmain has ever made a fan that spins at 13k RPM, the maximum has always been sub 6k, so there is something weird going on here, it's likely the fans you use are not stock and they are reporting wrong numbers, that could be very dangers because while your temps are okay now, and assuming the fans are spinning at 100%, if the room temp becomes a lot hotter, you will face problems.

The only way to tell if your miner is running at a good temp is by judging both the chip temps and the fan RPMs. You can ignore all of that if you are sure the room temp will not be any higher than it's today.

You don't need to pass any sort of KYC on nicehash, you just need to fill your wallet with funds and then rent the hashrate you want, but keep in mind there are two types of contracts you can buy, fixed and standard, you need to learn the difference between them and then decide what works best for you.

With that kind of hashrate, it will take you forever to find a valid share that would register on the pool.



There is no such thing but in general anything below a few tens of Gigahashes is pretty useless IMO.




It's the best or largest share you submitted since the last block found by the pool.


Same as the answer above (your hashrate is 200mh)



If you have free power or otherwise use the heat to warm your room, maybe it's worth it, if not then it's not.

If one of the members reports this topic - the mods might move it to the "Services" section, while this is mining-related, it may seem more of a service than not.

Most miners here including myself are small-sized miners, I don't think any of us around here can be potential clients, but at least, people who look for such a service using search engines might end up here.

With that said, try to post a few images of your software (to be taken seriously) by potential clients.

Good luck.

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.
