Nice summary you got over there, Last of the V8s brought this article to our attention in the difficulty thread, for those who don't want to read even the short version of yours, the study assumes the following.

1- The average cost for mining worldwide is 3 cents per Kwh
2- In 12 months from now bitcoin hashrate will double given that bitcoin prices increase by 25–35%

And here are my thoughts on their conclusion

Well, according to http://solochance.com (since I am too lazy to do that maths) you have 1 in 400,094 chance in every block that comes from now until your rental is finished, and just like the rest of us you need a ton of luck, so I wish you the best of ot.


Given the context, I am 100% possitive that he refers to BTC as bitcore core and nothing else,  kindly correct me if I am mistaken.

I know you don't, I tend to trust your words but it's common sense that you should provide a proof to support such a serious claim, I have interacted with you a lot of times and as I said I do tend to believe you, but if people ask for a proof you shouldn't take it personal, it's normal, now back to the real subject:

I highly think that there is something techinally wrong here, there are a ton of reasons why would your mining gear report less hashrate on the pool than shows on the miner status page, in order for anyone including the firmware devs to troubleshoot the issue - a few informations are needed.

1- Ping stats to the pool.
2- Screenshot from the miner status page that shows everything from time-elapsed, hashrate, hardware errors, stale, rejected, and etc.
3- Screenshot from the pool status showing all hashrate related details.
4- The kernel log.

There is a good chance that your gears simply didn't like the firmware and they were mining with a ton of hardware errors, or during the test your connection to the pool got lousy and a good amount of shares got lost in the way, or the miner was tunning for a whole hour or so (not exactly hashing to the pool) and you took that time into considerations, I mean there is a lot of reasons that can cause a huge difference of 14%, one of them of course is the dishonesty of the dev-fees which i highly doubt in this given situation.

I sent tasers a message on telegram, he will respond to your post soon (hopefully) he probably has an answer on how to go back to the original firmware, the difference in hash rate is huge to say the least, it is strange that you are the first to mention it, let us see what tas has to say on this matter.

To clarify on the price as it may seem like too much ($15 as opposed to maybe $5 or less for the regular fans) these fans are worth the price, they push more air and they don't make that whining/high-pitched sound that the low quality fans make, the only downside about paying $30 for fans that will be installed on an old S9 is that they might never ROI, the good thing about these fans however, is the fact that you can use them on all other Antminers.

My first impression was that nullius was a genius "Bitcoiner", I enjoyed his techincal posts and I did learn some great stuff from him, somewhere down the line he made a 180 degree change in the content he provides to the forum, he went from that tech-savvy member to a repuation-addicted member, he got himself involved in all the mess of forum trust issues. So if he ever comes back, I hope he goes back to development & technical discussion, the place where he performs best.

Just for the record Zhan is one of the richest people on planet earth, he sits on over 5 billion U.S dollars, he doesn't have any kids and no wife, and he is in his 40s, it makes me wonder, what the hell does he want?  I also think he is a terrible CEO and despite all the bad things about Jihan's Wu he makes a better CEO, since we don't have data on their internal issues/ personalities - we can only judge based on the quality of the miners they made.

From November 2018 until end of October 2019 Jihan Wu wasn't the CEO of bitmain, and we all know what gears were made during that period, YES! you guessed right, the terrible 17 series with 30%+ failure rate.

Did you try to press CTRL+F5 after flashing the new firmware? in most cases, the flash is successful using only the web update method but the browser's cache needs to be refreshed.

Also would you explain the reason/s for leaving Asic.to? what problems did you face? what did you dislike about it?

Indeed, that's great point phill,  you would include those under the "newbies" who make profitability calculation off by a good portion, really it's like slowing down when the traffic light is green because you can't possibly trust that all cars from the other roads will stop for the red light, it's common sense, assuming that all other miners run their gears at the same exact conditions as you are is plain stupid.


That's a nice read buddy, despite the fact that it could be off by 50% i tend to agree to many points.


So by July 2021 IF bitcoin price is at about $11,250 - 12,150$ hash rate should be 260EH or nearly double the current hashrate, sounds reasonable to me, but the price factor is CRUTIAL, taking their estimation of the average cost being 3cents per Khw, let's run some numbers.

S19         95TH  > $2150 for September batch > Makes $145 a month > ROI in 15   Months
S19pro    110TH  > 2900 for September batch > Makes $175 a month > ROI in  16  Months

The above numbers don't include pool fees, other operation and maitninace fees, it only takes powest cost of 3cents into account, these numbers are pretty terrible, assuming addition cost add 10-20% it will take about 18 months for these gears to ROI, 18 months is probably above their techincal lifespan anyway, and this assumes that difficulty states flat, it will be even worse with those miners who have FREE power keep adding more gears with 100% felixblity, with free power you ROI an S9 in 2-3 months, the incentive to mine at 0 power cost will always be there, it will only make thing works for anyone who pays a thing for power, even those 3 cents guys, let alone 4-5-6-7 cats.

The research is good, I wish it was done in the assumption that bitcoin price isn't going to increase, so if we have +100% difficulty and +35% price, if price is +0% then difficulty is +65% or about 200EH in a year from now.

مشكور اخي Omega على مبادرتك الطبية والرغبة في مساعدة صاحب الموضوع, اتمنى ان تخبرني بتكلفة ال Domain لمدة عام او 2 وارسال عنوان Bitcoin ليتم تحويل المبلغ عليه. شكرا

مرحبا بك اخي, اولا يجب ان تحذر من النصب, وكذلك يجب ان يحذر الاخرين منك ( هده الامور طبيعية هنا ولا تؤوخد على الصعيد الشخصي).

المشكلة في بيع الحسابات هي امكانية استردادها بالايميل, وحتى اعطاء بيانات الايميل للمشتري ليس كافي لانه يمكن ببساطة استعادة الايميل برقم الهاتف, لذلك ستواجه مشكلة في اقناع المشتري انك لن تقوم بخداعه, المشكلة الاخرى انه في حال طلبت "وسيط" لاتمام العملية ف 100% من الوسطاء هنا لا يقبلون مثل هده العمليات نظرا لخطورتها, انا لست على دراية بطرق استرجاح حساب من الموقع الذي ذكرته وهل هوا مربوط فعلا بالايميل او لا ولكن هده قاعدة عامة لبيع الحسابات, مع ذلك اتمنى لك التوفيق.

Yup 30 of them will differently turn the mining game upside down, but the real question is does Bitmain and other major mining gears manufacturer have the capalbity of supplying that huge number of mining gears? does TSMC have enough chips to sell? even if the answer was YES! on both questions, then time factor will take care of the problem since they can only make so many gears, also increase demand on products will take prices way to high which will make late commers reconsider their options PLUS the internal issue with bitmain (Zhan Vs Jihan) doesn't seem to be ending soon, all of those factors combined make me feel "bearish" ( I like the terms you used btw  ) on hashrate.


Many people including so called "professionals" work with the wrong numbers, it's hard for someone who live in EU or US to believe that there are hundernds if not thousands of megawatts worth of gears that run on FREE power.

So in short, you think that many investors are so stupid and hashrate will keep rising, I think that most people aren't stupid and hashrate will either stay flat or more likely drop slightly for months to come (given that BTC price doesn't make any considerable highs), since I am a miner myself - I am of course biased towards my thoughts and i hope you will be proven WRONG. 

اعجبني الاسم جدا, ان وافق daneal stev عليه سأقوم بدفع تكاليف ال Domain لمدة سنة.

اما بخصوص الواجهة فعلا عكس راي الاغلبية لقد اعجبتني بساطتها وتشابها مع شكل المنتدى, وربما هدا السبب الذي يجعلني ابتعد ان الواجهات الجدابة لانني ارتاح للباسطة اكثر, ولكن نظرا لان هده المدونة ستكون موجهة للاغلبية الساحقة يعني ان الخيار الامثل هوا عكس ذوقي تماما  , لذلك اقترح ان تقوم بما تفضل به الزملاء, اعتقد الاخ OmegaStarScream يفقه في امور ال web hosting و هده الامور وسيكون خير عون لك, لذلك ان وافقت انت على الاسم ووافق هوا على مساعدتك سأقوم بتحويل مبلغ BTC له يقوم بشراء الدومين لك.

بالتوفيق.

What do you mean by Difficulty target: 124 EH/s ? that's more like the current hashrate ! please elaborate, also calling Bitcoin "Bitcoin core" suggests that there is another Bitcoin, something that BCH and BSV people do to give the impression that thier versions of Bitcoin are also Bitcoin and not altcoins, if you get rid of the "core" thingy I would certainly love to join your channel. 

You have a valid point, in fact I have talked about this point several times in this very topic, I simply categorize all of these groups under the "Newbies" who enter a losing business, the only slight difference between newbies who take bank loans or spend their savings to buy a few miners and those investors is that in general, investors will make better decisions in most cases, the reason is the fact that they have so much money which most likely is the result of their proper planning or in the worst case scnerio - they would hire a proffesinal who would make business plans for them.

17,000+ S19s might sound like the end of the world but it's merely 1.615EH or 1.3% of the current hashrate, yes Core Scentific are not the only host who bought a dozen of these gears, and yes there are a dozen of newbies who have no clue about anything and they keep buying expensive gears that don't make profit, but there can't be so much stupidity to push difficulty any further, or at least I still have faith in humen beings and that the majority of them will do the right thing, as both phill and I have brefiely explained, with such numbers it makes 0 sense to mine, if someone is gambling on the price, then buying the coin would be a superior choice, if you are counting on other miners to leave the network before you then you might get the wrong bet.

Of course as I mentioned my speculation is based on the fact that most people use common sense, but even if the majority were plain stupid, those who have more brain cells will be able to kick those with less brain cells out of the game because by the end of the day you can only lose so much before you give up.

I won't claim that I know better than whoever told you so, but use your common sense, when F2pool goes down for maintenance or DDOS attack or whatever reason, how will a different worker name make any difference when the whole pool is down? using the same pool on a different port as a back-up pool hardly makes sense, let alone using only a different user name.


The minimum payout on Viabtc is 0.001, S17+ makes 0.000554 BTC a day as of today's difficulty, which means you need to mine for a total of 1.8 days or 43 hours on Viabtc in order to get to the minimum payout, based on your connectivity and F2pool stability it's almost impossible to get a total of 43 hours of mining on the back-up pool, it would take you years of mining, things will be better if you have more miners, but with difficulty rising you might not be able to withdrawal from Viabtc ever, so if you don't have another gear that uses viabtc as a primary pool, a solo pool as back up will be your best shot, it also helps with mining decentralization oneway or the other.


Well done, I doubt there is an easier way to find the block, and for privacy reasons, one shouldn't be sharing the block number/share because that may expose some details about them, I now know the F2pool username for member danieleither  , so if he wants to keep that private, he should change it.

Yup your S17+ found a block with a share of 29112178806450, nothing to be surprised about because after all, all of these blocks are found by a single miner anyway.

Anyway I have a comment on your backup-pools, I understand why would want to have the 2nd pool the same as the first with the 1st but on a different port, but based on my experience once your miner loses connection to the pool it doesn't really matter what port you connect to, so in almost everything your miner loses pool 1 it will go directly to pool 3, and since these large pools don't always go down you will only collect dust in viabtc, so if you aren't mining at viabtc with other gears it might take you forever to be able to withdrawal the dust, I would suggest your backup pool be Cksolo pool just in case you hit a block while the primary pool is down.

Happy belated birthday Jet Cash, I sent you some satoshis for coffee because I envy you, I am not even close to being as old as you are and I have already started losing motivation, but you at this age are still willing to learn and you are into crypto which is by default a thing for "young people". I wish you the best of luck.

This output powers the hash boards, all numbers you see here are DC, and based on INPUT of 220v, so at 220v input the power provides DC of 95A , so that's 16.32V*95A = 1550w , 20.04V*95A =1900w (not sure why they have 1850w) but doesn't matter.


This powers the fans and probably the control board (not pretty sure).


This is bullshit from Bitmain, they probably copied these data from the APW3/APW7 datasheet, don't trust them, trust the members who told you NOT to run your S11/T15 on 110-120volts circuit.

These words


Will get your topic moved to Altcoin mining and honestly, you will unlikely get any decent answers on there, so my advice is to keep this question related only to BTC mining, in fact, BTC is the only coin that is worth mining.

Now on the topic, if you won't use batteries based off-grid system (you shouldn't anyway) then you will need to have some sort of a good deal with the power company in regards to an on-grid/grid-tied system, depending on where you live all what solar can give you is 4-6 hours a day, in winter it could be as low 2-3 hours, so you will still need the grid, phill runs a large farm on solar but where he is located it has to do with tax stuff and his business model is profitable, you also need to keep in mind that in order to actually cover the cost of operation you will need to own more solar power than what you need.

Assuming you need 5kw, that will be 120kwh daily, a kw5 system will only give you 5*T where T is the number of hours of sunlight you get, let it be 5 so that's 25kwh daily, you are still 95khw short, assuming the rate you get from your power supplier is 1:1 (which is impossible) then you will need to sell them 95kwh worth of power in order to re-draw that when your solar panels aren't working outside of that 5-hour window, so you need to supply them with 95kwh in 5 hours that's roughly a 20kw worth of solar power, adding the initial 5kw, you need a total of 25kw system, this, of course, ignores all power loss factors, DC to AC and etc. and since you can't really get a 1:1 deal, you will probably sell your power for a cheaper rate, say you get a 1 to 1.5 rate, you will need 25*.1.5kw system so about 37.5kw to run 5kw 24/7 for almost free for 10-20 years.

phill knows about solar a thousand times more than I do, so he will probably correct me if I made a mistake somewhere.
