As long as the screw is tight enough and the connection isn't loose - there shouldn't be a problem, I highly doubt that reason alone is what killed the PSU, what is your input AC voltage?

This is based on the assumption that the miner you buy will generate more or at least the same amount of BTC which you can buy directly from an exchange otherwise, but that is a false thought and things don't work that way.

When you head to exchange and pay 34k - you are guaranteed to receive a whole BTC which according to your strategy can be held until it hits one million dollars, there will be zero operational cost to hodl that BTC, but if you pay 34k to buy miners instead, there is no guarantee that they will generate a whole bitcoin before they die, need major repair or simply become obsolete and the power bill exceeds the income.

We have run the numbers a dozen times and you will find many posts talking about this, it's very unlikely that any miner will generate the same amount of BTC they could have directly bought, or else, there would be no debate about whether mining is better/worse than buying the coin directly, if you look at the difficulty chart and compare it to the price you will notice that the difficulty always goes up and the correction to the downside only last for a few epochs, where the price can go down for years, another thing is that that the difficulty grows faster than price does (all of these facts can be seen in the history data)


DCAing bitcoin is indeed a great strategy, but mining isn't a different way to DCA, it's a completely different strategy, when you throw 8k at an S19 pro today, if the price drops to 15k the next week, there is no DCAing for you, I know you might be thinking that if the price falls down to 15k then the difficulty will drop 50% and thus your earnings in BTC won't be affected, but that isn't the case either, the price can drop 80% while difficulty goes up 100%, and we have seen this happen many, many times.

There are of course expectations, and there are many people who mine more bitcoin than they could have bought, but this requires

1- Getting the gears at a very good price
2- Having a very low power rate
3- Starting at the right time of the cycle
4- Lots of prayers that the Chinese piece of gear which has little to no quality control will not break in 2 weeks.

I mentioned this a few weeks ago but some folks said it would be easy to migrate all of these gears,  it's easy to underestimate the implications of running a mining business, it's also easy to ignore the fact that the shut-down happened in the midst of the rainy season in China, in other words, many gears were running at power rates as cheap as 1-2 cents, so where else can they mine and make a profit? also, there is probably no single place on planet earth that has the infrastructure to run all those gears.

Core Scientific that owns one of the largest mining operations in the world said they have 80k gears this year, and that they are trying to build the infrastructure needed to host 220k miners by the end of 2022, that will hardly hit 20EH assuming they use only the most effienct gears in the market, of course, they are not alone, but this should give you a general idea of how difficult it is to gain back the 70 or 80 EH we lost, it will take some time.

Well if you cherry-pick the period you want, your theory will be valid, but you can only do that in theory, because selling coins directly is a lot better when the price after time+n has gone lower, so if you start mining say 4 months before we reach to a price peak which is followed by an 85% drop in price over the course of 16 months, then selling the coins as you mine them would be a lot better as far as your fiat earnings are concerned.

Again it all depends on what happens in the future, selling could be to your advantage or disadvantage, you can't tell until enough time has passed.

Yes, a few options out there, paperweight, door stoppers, and whatnot, the good thing is that all metal prices go up in price over time, the scrap value for these miners will go up in the long term, there is a fine quantity of aluminum in them, and the fans can be used for something else, IIRC the scrap value for T9 in China back in 2019 was about $15-20$.

Why would you say no? the Chinese sell miners every day, it all depends on your expectations, most people falsely believe that the Chinese are rushing to flee with their gears and that the police are after them and thus they would sell their gears for the first buyer they meet, that couldn't be further from the truth.

Mining gear prices did drop compared to say 3 months ago when bitcoin was at 60k and mining was ok in China, but nothing too crazy, S19 pro still trades between 8-9k in China, used S9s are back above $200 (most clean gears will be in the 250-300 dollar range), Used M20s are 3k each, M21s is anywhere between 2 to 2.5k depending on the hashrate, so if your "kids" can pay these prices, they can buy all the gears they want.

My initial guess is that your Chain 6 has a dead/toasted chip probably in the first domain, if that is the case, this board is more likely beyond fixing, you might get lucky by flashing a different firmware (don't flash the latest once if you don't have a Sdcard to unload it later), but in general, you should just assume it's dead, to confirm this theory I need to see the complete kernel log or at least the part where it does the chip count, if you don't know where that is, copy everything.

This is how sellers on Alibaba/Aliexpress usually scam you, they don't just ignore you and walk away with your money as that will bring them troubles, instead, they send you a terrible product that usually just doesn't work as advertised, in many cases, they might just send you a different product.

The problem with buying mining gear is that the seller needs to be trusted, they all offer you a Video-Proof showing how the miner works perfectly, but these videos can be easily faked, and then they will blame the shipping company or anyone else and insist that they tested miner before shipping and that they have the video tape as a solid proof against your claims.

Instead of writing everything from scratch,you can use BTC pool open-source project, I think Viabtc also have something similar, there will be some word required so if you don't have any programming knowledge you will need to hire someone.

Phill, you have a good point there, I see some lack of interest in SHA256 gears on major telegram mining groups, many folks are looking at the altcoin Asics, while I genuinely believe they will all get rekt because those coins' difficulty can double with 1 or 2 batches of gears, it's a net positive for bitcoin's difficulty, think of someone who wants to invest 10M in mining, if they buy L7+s instead of S19 pros or M30s, it's a good thing for all the folks that mine BTC.

I quoted this for future reference, I have also added a warning in the original post which directs to your post, I will only remove it if you state that your issue was solved or if Myrig responds and convince the community that you are making things up (which I honestly doubt), meanwhile you should prepare all proofs that support your case and if I see enough evidence I'll tag their profile and get more support from other DT members to do the same.

Their profile has been inactive since June 07, pretty close to the date you mentioned, which leads me to think that this could be a single person who does everything from fixing to taking care of the clients, and once he is gone, everything is gone along with him, which makes it a very bad idea to deal with them if that was actually the case, but let's wait and hear from them/him.

Please try to contact them on support@myrig.com since that is the email they have on their profile, you might as well send them a PM.

اخي يحى اسف جدا فأنا لم الاحظ هدا الموضوع, كان المفروض تذكر اسمي بالانجليزي ليصلني تنبيه او ترسل لي رسالة لتنبيهي بهده الموضوع.

هل قمت بحل هده المشكلة؟ وهل لديك كرت واحد على هده التجميعة ام اكثر؟ ايضا هل قمت بتعديل اي شي في اعدادات الكرت ام انه يعمل على الاعدادات الافتراضية؟

اولا مرحبا بك اخي هيوج وكل عام وانت بخير, وكل عام وجميع الاعضاء هنا بخير انتم واسركم الكريمة.

طبعا وكما يعلم الجميع فأن القسم العربي ابتدائا من العام الماضي لم يكن ياعني ابدا من نقص في نقاط الجدارة خصوصا بعد زيادت حصتك والاخ Sygambler و Omega وثم هدا بعد طلب مباشر للادمن والذي بدوره تفهم الامر واتقدم له بالشكر على ذلك.

قبل تلك الفترة كان هناك نقص واضح في نقاط الجدارة لان المشاركات كانت كثيرة والنقاط قليلة, بعدها كترت النقاط ونقصت المشاركات, طبعا السبب الرئيسي كما اسلف الاخ ضياء هوا عزوف الناس عن المنتدى بصفة عامة, فمثلا الاشهر الماضية حتى في قسم التعدين الانجليزي كان هناك عشرات بل مئات المشاركات يوميا, اما منذ 3 اشهر تقريبا فالقسم يلاحظ كساد واضح وانفخضت المشاركات بنسبة 80-90% على اقل تقدير.

تم ايضا تعيني كمصدر جدارة بعدد متواضع من النقاط ( اقل بكثييير من نقاطك وهدا طبيعي لاني اعتبر جديد في مجال مصادر الجدارة وتحت الاختبار اما انت فتجازوت الاختبار ويبدو ان الادمن راضي جدا عن ادائك) وذلك حسب طلب مني لتلبية حاجة قسم تعدين البتكوين الانجليزي الذي يعاني شح واضح في مصادر نقاط الجدارة, طبعا هدا لا يعني اني لن اقوم بارسال نقاط جدارة للقسم العربي لاني شخصيا اتحصل على نقاط جدارة ولدي الحرية في صرفها كما اشاء, اما بخصوص النقاط التي تمنح لي بناء على طلبي لدعم القسم الاخر فسوف تكون للقسم الاخر حتى "يجد شيء ماء".

اما بخصوص سؤالك حول الية التعامل مع نقاط الجدارة, من وجهة نظري المتواضعة ان المنشورات التي تنشر لغرض الحصول على نقاط جدارة او لزيادة الرتبة اي انها لا تحمل اي فائدة فلا يجب ان تتصحل على اي نقطة جدارة حتى وان كان لديك مليون نقطة تريد ارسالها, يعني المشاركات  التي تصنفها انت "عادية" لا تستحق نقاط جدارة.

اما اي منشور او تعليق يحمل قيمة ويضيف شي ولو كان بسيط فلا مانع من ارسال 4 او حتى 40 نقطة جدارة له, طبعا بناء على توصيات الادمن انه من الافضل ان ترسل 50 نقطة جدارة لمحتوى جيد نسبيا على ان تدعها تنتهي صلايحتها وتدهب هباء, وهنا يجب عليك ان تقدر وقت تواجدك في المنتدى وكم منشور يمكنك التدقيق به, فلو كانت احصائيات هي انك شهريا يمكن ان تتابع في المتوسط 200 منشور, ولنقل ان نصها يسحتق نقاط الجدارة, يعني سوف تعطي نقاط ل 100 منشور من رصيد 1000 فتعطي 10 نقاط لكل منشور, ان كنت تعقد انك ستقيم 1000 منشور فتعطي 2 وهكدا.

طبعا يوجد استتناءات للمنشورات المتعوب عليها جدا والتي تقدم قيمة كبيرة جدا, يمكن اعطائها ضعف المعدل العادي, والاهم من هدا هوا قبل نفاد صلاحية النقاط ان تحاول توزيعها ولكن ليس بطريقة عشوائية, مايفعله الاعضاء الذين لديهم الكثير من النقاط لا يمكن ارسالها هوا ان يرجعو الى منشورات قديمة قامو باعطاءها نقاط واضافة نقاط جديدة لنفس المنشور, بهدا الامر تضمن انك لن تضيع النقاط ولن تعطيها لمنشور لا يستحق لانك قمت باعطائه نقاط في الماضي يعني انه يستحق وبهدا تتخلص من نقاط الجدارة التي لم توفق في ارسالها بسرعة عالية بدون خسارتها.

وبهده المناسبة اتوجه لك بكل الشكر والعرفان لما قدمته للمنتدى العربي من دعم, ان تكون مصدر جدارة ليس بالأمر الهين وبعد عدة ايام من تعيني كمصدر جدارة ادركت ان هدا الامر ليس سهل بل هوا مسؤولية كبيرة على عاتقي, لذلك انا ممتن جدا لك ولكل مصادر الجدارة في القسم العربي الذين واصلو جهودهم لدعم هدا القسم خلال السنوات الماضية. بارك الله فيكم جميعا.

I don't know how taxes exactly work where you live but to me and probably to some others, tax is completely irrelevant in this subject, and as far as reselling hardware, you have too keep in mind that if you sell the gears because they are no longer profitable, then they will be worth close to nothing, the S9s were bought for 5k in 2017 and sold for $80 in 2018, not such a grear resale value if you ask me.

Obivislouly, if you were lucky enough to have bought in the right time, and ended up profiting, you will be able to sell the gears for a much higher price, some of those folks who bought S9 for 80$ sold it later for $500, in other words, if you end up winning, your gears will add to your winnings, if you end up losing, the gears won't cover up much.




Maybe if you apply this against infinite time period, but then you can't, because you can't run a mining gear for infinity, the gear will die within a few months/years or will consume more energy than profit and will have to be shut down, and thus in the real world, no, everything does NOT balance out.

There is no certain answer to this ongoing debate of mining vs buying BTC, there are many factors involved, but if you were to take a large enough sample over a long enough period then without a shadow of a doubt - buying bitcoin would be more profitable by a few orders of magnitude.

It is not the "best" gear, it's simply the most effienct gear, I don't know what's your definition of best but to me the S19 pro isn't the best gear out there, because efficiency isn't everything, but that's not like a universal rule, it's just my personal opinion, what matters the most for me is ROI, i always pick the gears which has the fastest ROI, I don't care much what happens after.

Of course, I avoid gears that overheat like T9+, or gears that are very inefficient because power is always limited and I want to maximize my hashrate, also gears that are known to have high failure hash rate, but all those technical aspects aside ROI is the most important factor in my book.

The S19 pro seems to be a solid gear so far based on the reviews (it has some PSU issues that a few folks reported), but what's bad about it is the price, the ROI is way too much for me, for your power rate at current difficulty and prices, it's 12-13 months to ROI on those S19 pros, usually what you see on the calculator today is only going to be worse.

There are expectations, you can assume that difficulty won't go up by much, and that price will hit 100k in 2 months and thus you would ROI in say 6 months or less, that's always a possibility, one which I rather not bet on when making business decisions, the other possibility is that BTC price will remain the same or go lower while difficulty keeps going up, this will extend the ROI period, while that isn't a certain scenario but I rather bet on it than against it.

Keep in mind that most people think I am rather very pessimistic when it comes to the price of BTC, but I remember very well when I was telling everyone not to pay 15k for S19 pro a few months ago, but the charts were green, everyone was saying 100k and I must have sounded very stupid to say otherwise, here were are now, with S19 pro making $30 a day as opposed of $50, and I see that things will only get worse from here on.

So bottom line, 10k for S19 pro does not seem like a deal I would take even if I had 0$ per Khw power rate.

That's not true, they ordered mining farms that use clean energy to shut down as well, mining farms in Sichuan which most of its power sources come from hydro were also shut down, it started as "fighting coal operations" but "There's more to this than meets the eye ".

It is a lot more feasible with 6 cents that's for sure, this rate is the average for the industry and thus your chances of making a profit increased by a few orders of magnitude, what I don't like about this business plan is the S19 pro part, it's way overpriced and since you can get 6 cents per Kwh that is sort of an edge which you have to make use of, people with free power buy T9+ which is about 10$/th, those with 1-2 cents buy S9s which costs about 14$/th today, so paying $10,000 for S19 pro at a cost of $90/th is without a doubt a terrible idea, let's just make a simple assumption that whatever the ROI that shows now is going to be shifted by 50%.

S19 pro ROI = 10,000/ 770 = 13 months * 1.5 = 19 months > terrible.
M20s (used) ROI =3500 / 390 = 9 months * 1.5 = 13 months > bad.
T17 (used)  ROI = 1700/ 250 = 6.5 months *1.5 = 10 months > not so bad.

*These are based on 6 cents Khw, prices in China + 300-500$ for shipping and duties, the T17 is a terrible gear, it was just there in the reseller list I got recently so I used it

But you get the point I suppose.

Of course, you can go to as low as S9, ROI will be $300/60 = 5 months * 1.5 = 7.5 months, but then it will be a bit risky because if the price drops a bit of difficulty goes up a bit that 60 bucks will disappear and you will start losing, unlike the S19 pro which has a ton of room for profit, these are some of things you need to consider, there is no right or wrong about it, it all depends on your risk management.

Other important factors such as failure are also important, investing 10k in a single gear means that if one hash board is dead, you lose about 3k worth, investing in 3k gear you only lose 1k worth, of course investing in 10k gears means less work and easier management, but everything comes at a cost.

Also, the availability of mining gears in your country is very important, for example, if you want to be in the mid-range risk and go with say M20s, but then find out it will cost you 7k instead of 3.5k, then the S19 pro will be a lot better, if you get lucky and find S9i/S9js for 200$ then ROI is only 5 months and thus might be worth taking the risk, I can't tell you what gears to buy ( don't buy any 17 series from Bitmain because they have high failure rate).

The 1.5 factor isn't something you can count on, it's just a speculation, if your risk tolerance is strict, make it a factor of 2, if you are a risk-taker, you can just work with a factor of 1, there is really no perfect model that fits everyone, I can't tell you what to buy and when to buy, but I hope I gave you the key points which you need to consider before entering the business.

On your FB page you say


These are serious claims that need serious proof, I can't possibly add your service to the list with little to no information that I know about you, can anyone vouch from you? if not from this forum, have you done any deals with known people on major telegram mining groups? as it stands right now, you don't seem to be trustworthy, given the number of scams you should understand why everyone here would be skeptical.

If it's a good deal in Germany, you might want to figure out a way to sell that power you generate, but with 19 cents kWh you can't possibly profit from mining.



Price can go both ways for years, the difficulty only goes up in the long run (facts are in the charts), your profit will decrease every month more often than not, all these online calculators are misleading, people who bought S19 pro 6 months ago were also looking at a 1 year ROI, it's now still 1 year ROI, they are not even remotely close to ROI.


Where did you get that 65k from? you said S19 pro, today it costs 8.8k in China, so without tax or shipping it's already 70k, with tax, shipping, wiring, and whatnot you will be closer to a 100k than 65k, and no, 8 S19 pro will not make you 2.4 BTC in one year, you have better chances to walk on the moon than making 2.4 BTC with 8 S19 pro in a year.



This is investment advice, and telling you to go for it ( like the first post which is terrible advice) or not, isn't something anyone should do, but if you ask it in a different way, you might get an answer, if I were you, I would NOT go for it.

There are a dozen topics that discuss mining vs buying bitcoin vs keeping your money in the bank, just search the forum and you will find many, some folks who usually never owned mining gear might tell you to invest, most of the folks who know how mining actually works in terms of business - will tell you you should not even think about it.

I am 100% sure you will end up losing money? of course not, but it's an easy bet, you are more likely to lose money than not, I'd say it's easily 20% vs 80%, I would be very surprised if you end up making a profit.

See mining isn't like other businesses where you can expect an increase in demand, if you start a coffee shop tomorrow, you are likely going to benefit from the increasing demand for coffee, more people grow up and want coffee, so the competition factor is not so huge, with mining, however, the rewards are fixed, and they only go down in time, so the competition factor is everything, then comes the question, who are you competing with?

You are competing against people who

1- Have FREE power
2- Very cheap power rate
3- Access to cheap mining gears
4- Pay no tax on income
5- Pay no tax on import
6- Pay $5 an hour for a certified electrician 
7- Pay $3 an hour for someone to install/maintain the miners

And the list goes on and on, every point here counts, these points are like the weapons you take with you to the battle, the more the better, being in Germany you don't have access to cheap gears, you have to pay import and income tax, you can't hire an electrician for $5 an hour, you are going to war with your bare hands, the odds of winning are extremely low.

The average price for the past epoch was between 33-34k, so far it has been below that by about 5%, but despite that fact, it will be extremely difficult for the difficulty to drop below its current levels, the model i use isn't something you can count on 100%, but I believe it has a fairly good chance of being accurate, and it's rather simple, gear prices in China go up = difficulty will go up and the opposite is also true, so far the prices have been climbing up every day, it means more and more gears are being sent out to new places, what we can hope for is that the process of re-powering all gears will take many months.

The other possible scenario would be a large drop in BTC price, something like 20-30% to the downside (which is very possible), that should suppress the difficulty for a while, but overall, the only way is up.
