Turbartuluk, thank you again for doing another nice contest.

Alas, you have to learn to read things in thier context, i said


Also, "everyone who is following pools' share hashrate" do it with a software that reads the blockchain and put it into a chart/table, that is fine, what is not, is people copying the already available charts and thinking they have spotted something that nobody else know about, and creating some stupid fud on how 51% attack is going to happen because a few pools have 51% of the total hashrate, those same people have no clue that this is no news and it has been the case for a decade.




This is not how mining works, and I am not going to explain why because then you will just get upset and take it personal again.

No they won't, not in every place, i explained that in detail in the exact post you qouted, not sure how to explain it better but every place is different, what applies to your city/country does not have to apply everywhere.

No, I do not want to solve any problem, I am just stating an existing fact, those transformers were not hooked up randomly, when the electric company install those transformers they know for sure that even if they were to go full-load their infrastructure would hold up, the short version of this, is not every city is approaching it's full limit of power, many countries have a ton of "idle-power" sitting there doing nothing, you just need to create demand for it and off it goes.

بكل تأكيد فأن بيع اي كمية من اي سلعة يؤثر على سعرها, ولكن لدينا في الجانب الاخر "الطلب", فمن المهم جدا فهم "الفوليوم" فمثلا اليوم كان فوليوم البتكوين 10 مليار دولار, يعني انه تم تبادل ماقيمته 10 مليار دولار من البتكوين في طلبات بيع وشراء, مما يعني ان مبلغ 2 مليار ليس بالرقم المأهول الذي يدعو للقلق حتى وان تم عرضه في نفس اليوم, في المقابل مثل هدا الرقم يمكن ان يفقد عملة اخرى نص قيمتها في يوم, الامر كله مرتبط بحجم سوق العملة وفوليوم التداول.

الولايات المتحدة صادرت مايقرب عن 259,112 بتكوين باعت معظمها مسبقا وكل ماتبقا لها  69,640 بتكوين فقط اي حوال 2 مليار دولار, حجم سوق البتكوين 590 مليار دولار, فوليوم التداول اليوم فقط على عملة البتكوين تجاوز 7 مليار دولار, يعني الخلاصة ان مبلغ 2 مليار من البتكوين ليس له تأثير قوي على السوق, يمكن ايضا مقارنت ذلك الرقم بما يتحصل عليه المعدنين خلال شهرين فقط, يعني ان الموضوع ليس مخيف باي شكل من الاشكال, مايخيف اكثر هوا صدور قوانين جديدة بخصوص البتكوين مثل منعها او معاملتها على انها عملة وليس سلعة وغيرها من الاشياء التي قد يكون لها تأثير سلبي عميق وطويل المدى على البتكوين, اما عمليات البيع سواء كنت من الحكومات او الشركات فلن يكون لها تأثير سلبي فهده العمليات هي جزء طبيعي من حركة السوق.

Ya, this is why I told you every place is different, where I live during summer and winter electricity is consumed like hell because we have no other means of cooling/heating when temps are 40c outside, you bet that every AC is going to be spinning 24/7 when winter comes, we rely on electricity only,  in fact, many people use the electric stove to cook (those consume no less than 2kw) so that 1000w that a whole house in your area use is not even enough for a single person here, probably the same for many other places.

And then you have different building sizes in the same area, you find a small house next to a 3-story building when the electric company supplies the small house they need to take into account that one day, the small house could turn into a 3-story building, and then what's even worse, a small house could have an AC in every room, uses an electrical stove to cook food and consuming more than another house that is twice the size.

So with all that in mind, adding a couple of miners will certainly go unnoticed as far as the electrical company is concerned, of course, this changes if the electric company uses some advanced tools to check for load type or harmonics created by PSUs, but just by looking at their amp/kw reading, they can't tell.

300amps gets you about 66kw on 220v, so that's 18-20 of the latest couple of generations ASIC miners.

Keep in mind that buying used mining gear is very risky, they all come without a warranty, I suggest you buy a few new asics than buying a lot of used miners that will die soon, but if you insist I can offer you used gear without warranty, just a testing video to prove that you are receiving the same miners we are sending, and ones shipped we are no longer responsible if that works for you -- send me a list of the gears you are interested in and I will send you a quote.

If you want brand-new gears, you can check my topic in the hardware market section or ask me about any type of miner with your desired quantity and I will send you a qoute.

There are right about a dozen wrong statements in your comment, mining to your own node is still possible, using the word supported is rather wrong because that brings up a question; "supported by who"?

Mining to ones node will always be possible given how BTC works, it's just a question of feasibility and nothing more.



Every block found on the network is found by a single small miner, many people mined individually and managed to find blocks, some did that with USB sticks that don't mine faster than a few gigahashes per second, besides, we don't know OP' hashrate, he could be mining with 10EH worth of hashrate, so his chances of finding blocks mining to his node are a lot larger than the changes of couple mining pools combined.

The only drawback of mining to your own node would be the reliability aspect, mining isn't just about getting lucky and hitting a block, you need to stay constantly synced with other nodes, and you need to have a very fast connection to other nodes (especially the mining ones), block downloading, processing, and prorogation are very sensitive and there is zero room for error, it's plain stupid to risk losing blocks by mining to a node that runs on an old laptop sitting in the garage hooked up to your not so reliable 10mbps ADSL.

Given that all those private keys were generated by the same person/people, there is a slight possibility that a pattern of some sort does exist tho that's pretty unlikely, given that someone has already managed to break #125 it means one of two things:

1- Somebody managed to find a pattern somewhere that reduces the search range by A LOT.
2- A large corporation invested some serious money in a few thousand GPUs and people like OP stand no chance of finding those keys first.

I think the second point makes more sense, having access to a truckload of GPUs and a better-modified code is probably what those folks are doing, it looks like the same person has solved both #120 and #125, so they are up for something, the "difficulty" of the puzzle has hit the ceiling now and the small guys have little to no chance in it IMO.

Also, I am not sure why OP wants to use an ASIC miner to brute force a private key, it makes no sense.

من وجهة نظري من الجانب الفني للتحليل فأن العام الذي يسبق ال halving لايكون فيه سوق صاعد بشكل كبير بل يتحرك السوق بشكل افقي في نطاق ضيق حتى حدوث الهالفين, وبعدها يبدا الصعود ببطيء لفترة 3-4 اشهر من ثم يبدا الانطلاق نحو قمم جديدة في خلال اشهر.

ان كان التاريخ سيعيد نفسه فانا اتوقع ان يبدا الصعود الحقيقي للبتكوين في شهر ابريل العام القادم على اقل تقدير, والقمة الجديدة ستكون في الربع الاول من 2025.





نلاحظ في التشارت ان الخطوط الزرقاء هي تواريخ ال halving والخطوط الصفراء هي 9 اشهر قبل حدوث ال halving وهوا يمثل تاريخ اليوم, يوجد فرق بسيط بين انقسام 2020 و 2016 ولكن العامل المشترك بينهم ان الصعود الحقيقي لم يبدا فعليلا الا بعد الهالفينق ببضعة اشهر, ونلاحظا ايضا ان دورات الصعود تتقلص, ففي الدورة الاولى تحصلنا على 16 شهر من الصعود, بينما في الدورة الاخيرة تحصلنا فقط على 10 اشهر قبل الوصول الى القمة الاولى والبدء في التصحيح, مما يعني انه على الاغلب فأن دورة الصعود هده المرة ستكون اقصر من 10 اشهر.

This isn't a problem everywhere, electrical load is just electrical load, whether it is for mining or powering up a new AC / heater it makes little to no difference, I can personally fire up to 15-20kw of miners where I am staying right now and nothing will happen, many citizens oversize the power infrastructure to account for future expansions, families grow bigger, houses grow bigger, the number of houses increases, the demand for energy is increasing and many things that did not need electricity before -- need it today.

I understand that in many other places, adding 10-20% more load will break things, but that isn't because of mining, it's just because of poor planning by the electric company, long before mining (20 years ago or so) when using split AC become very popular in my city, many transformers started to break, main breakers had issues, wires were heating, and they had to change almost everything to account for those changes.

It makes a huge difference between an average house using 2 ceiling fans, a fridge, a few lights, and a TV (not even 1000w) and a house that uses 2 ACs, 2 water heaters, 2 washing machines, a vacuum cleaner, and what not, just the lifestyle of the people can increase consumption by 500% easily, so ya, old cities that still use the old infrastructure will break if every house added a single S9, whereby a modern city where they calculated the new average based on all the new (everything electric) and added a good 30-40% for future expansion won't have a problem if every house run a miner or two.

In my hometown, some remote houses have their own 100kva transformer just because they are a bit far from the nearest transformer, so instead of running expensive large wires at 240v, they just run the 11kv and drop a transformer a 100kva there, maybe a few years later someone else builds a new house around, so ya, many houses in many cities have access to a few tens of KWs which they could use without breaking a thing.

Before the China ban it was Bitmain with their pools (Antpool, BTC.com and Viabtc) arguably even Poolin which was founded by an ex-Bitmain employee before the 2020 lawsuit, and then, on the other side, you had F2pool, those pools combined always had well over 50% of the total hashrate, and don't be fooled by all the names, essentially, 2-4 Chinese men sitting in closed room had the final say on what to do with all that hashrate.


Fast forward, China banned mining, and U.S players started to get into the business, creating their own mining pools, and now it's no more 2-3 Chinese men, it's 1-2 Chinese and 1-2 Americas, still the same number of entities who control well over 50% of the total hashrate, and since BTC doesn't care about those folk's nationality or names, nothing has changed in terms of hashrate distribution.

 
I have been professionally mining BTC long before this topic took place, and I have been following hashrate distribution years before Foundry USA pool came into existence and the fact that 2-3 entities owning over 50% of the hashrate have been the case since at least 2016, it's a lot more than just looking at a pie chart and thinking you solved the puzzle, you need to understand how are all these pools are connected, then use that knowledge to compare hashrate distribution for the past decade, and you will come to the same conclusion.

Furthermore, pool distribution is pretty irrelevant compared to gear ownership and the physical location of that hash power, at least 80% of the hashrate comes from a single manufacturer, that's more to worry about than some random pool distribution which can change drastically over the course of a few hours, the physical location of the gears and the law which they operate under is also a serious matter.

I'd rather see 3 large pools each owning 33% but hashrate divided between 50 different countries where no country has over 10% of it, rather than seeing 100 pools, each with 1% hashrate but 70% of that hashrate located in the same countries with the same laws and regulation, even worse, that majority of that 70% is owned by a single entity.

This is a serious claim, to say the least, as far as I understand the main pro of two-phase vs single-phase would be a slightly better PUE, I am not sure how two-phase system would have a lower OPEX by saving a few tens of dollars in pumps.

With two-phase you are still going to need to add new components that are not needed in a single phase, and the main issue with be the use of Fluorocarbon-based liquids, which are EXTREMELY expensive compared to the hydrocarbon-based liquid used in a single phase.

Here is a study showing that the loss of the liquid was pretty high to the point that having that better PUE was questioned.

Now, personally speaking, the cost of the two-phase 75KW is $37,000. if we compare that to one of the single-phase setups, the total cost would be a lot less than 50%, I find it very difficult to justify such an investment, mining a short to medium-term business, if OPEX will only start to look better after 50 years then it's a no-go.

Thanks for answering my questions.

Might as well add the 10% of Viabtc to Antpool and that would give you over 60% controlled by two entities (Foundry and Bitmian), while Haipo Yang tries his best to deny the fact his pool isn't indirectly owned by Bitmain, his attempts just keep failing, judging by the who is the largest investor in Viabtc, and the team that founded Viabtc, you can clearly see that it's just another branch for Bitmain.

Although, as I mentioned before, this isn't new, and there is nothing to worry about, 2-3 entities owning over 50% of the hashrate has been the norm for many years, and will always be the case.

Depending on the technology the power company uses - it should not be so hard to find those operating mining gears at home, unless it is below 1kw gear that makes next to nothing in profit.

The average home around the world wouldn't need as much as a single new gen miner, a small house the draw on average 5kw an hour is likely mining some coins.

Different regions have different figures to look at, where I live, electricity is the only source for both heating and cooling, so a house drawing 5kw in summer or winter is normal, i am sure this is way above average.
 

By looking at the feedback you left on each other's profiles, none of them have any real value IMO, BitcoinGirl.Club can't prove that Ratimov posted all those topics just for merit (I personally don't think he did it for the sole purpose of merit), on the other hand, Raitmov accusation against BitcoinGirl for plagiarism is weak, all I see is "misuse" of citation or lack thereof, without the intention of  "plagiarism".

Furthermore, even if those were legit feedback, they serve no purpose now.

It's pretty obvious that the two of you have hit a wall and going back to being "normal" or "friends" is just not going to happen, then you two should at least be "respectful enemies" by doing this:



Sounds like a perfect plan to me.

looks like an interesting project, alltought a lot of important details are missing, such as your target selling price, estimation of total cost, and all that, but my question is; since you are targeting small miners, why use two-phase immersion cooling? while two-phase immersion cooling is more efficient than single-phase immersion cooling, it's rather more complex and a lot more expensive.

I understand that maintenance and components could be less in the two-phase setup, but the initial cost and availability does not favour it, would like to hear from you.

Ya, 6.5 cents isn't all that attractive, to be honest, but anyway, regarding gears going into Russia, it's pretty easy when done from China/HK, not sure about from EU/USA, I can sell Whatsminers M50 120th in Russia for $1830, which is slightly cheaper than the U.S because shipping is cheaper to Russia.

So ya, paying 6.5 cents while mining in a country that doesn't have very clear laws regarding mining is rather risky, I rather pay 7-8 cents and mine in a place with clearer rules.

هده الجملة تذكرني بكلام قد قاله Saifedean Ammous صاحب كتاب The Bitcoin Standard حيث قال بما معناه " الوقت المناسب للقضاء على البتكوين قد فات" في سياق لشرح ان محاربة العملة كان يمكن ان يجدي نفعا لو كان في المهد, واتذكر هدا الكلام منذ سنوات طويلة, مما يعني ان الان الموضوع اكثر صعوبة, حجم العملة السوقي وحجم الهاش ريت قد تضاعف لارقام كبيرة جدا تجعل من اختراق البتكوين كشبكة (لانتكلم على اختراق محفظة او منصة) امر شبه مستحيل, ومع مروم كل يوم, تزداد الشبكة قوة.
