I have heard that argument before, it's simply based on the fact that mining pools operate and can operate without any regulations , license or KYC of any sort, so most mining pools won't be forced to handle information regarding their clients, so think about it this way.

A fresh block > miners, this is a single transaction which says pool xyz sent x bitcoins to abc and that's all about it, so even knowing the mining pool that created that output you can't do much with that information, unless the pool hands you the information of that miner such as their IP address, total hashrate and other addresses they might have used on the same account.

With exchanges however, since most of them involve the use of fiat money wether to buy or to sell crypto, they are subject to regulation, exchanges that require no KYC will soon be history , we saw how binance turned around recently, it's just how things are, if you own an exchange and want to operate freely worldwide you will have to obey the rules of  world (more so the U.S law).


But then, under some circumstances, regulation can get to mining pools as well, the government can even access the pool's server with court warrant, a less "democratic" government can detain the pool's owner/s' and force them to hand out those information, so mining to a pool isn't really as "private" as most people think.

With that said, there are still better and more secured ways that ensure better privacy, using a good mixer makes your coins a lot harder to track than mining to a mining pool.

Kano owns a mining pool so chances are this "shot" is biased, he has problems with almost all pools except his, he claims that some of them have bad code, some have bad owners and the rest don't have good resources and a lot more points he always has to say to any other mining pool.

With that being said, I agree with Kano (I very seldom do) that the word "first" simply means first, there are other more "honest" terms they could use, personally, it's extremely unlikely that I'll tag their profile or anyone involved with negative feedback just because of this small matter, I might (if slush refuses to fix that word) put a neutral on their profile saying "they are not the first pool, at least 1 mining pool was there before them".

I also doubt that any reasonable DT member will go to as extreme as negative feedback just because of this, however, the lost blocks could be worthy of negative feedback, if there is enough proof and at least one victim coming forward to strengthen Kano's claim.

we call mining asic "gear", I hope that is clear enough by now.

The problem with your request is that you have a good amount of money, free power but 15kw is really too small, in order to fully utilize the free power aspect, you need to be using cheap gears that are less effienct, such as antminer S9s, but then with that small amount of power, you will only be able to have just about 10 of them, which is a total of 140th.

Including racks, wires, and all, that will be in the 7k range, which is nowhere near 60k, but then 140th is really not worth the efforts IMO, yes 10 S9s will get you 1.2k monthly based on today's prices, say you will spare $200 to buy replacement hash boards/PSUs, so maybe you net $1000 a month, but I think the current figures will be the best you will ever see, in other words, this 1k isn't sustained by any means.

the other approach would be getting efficient gears to get the maximum hashrate squeezed in those 15kw, but then you lose that "edge" of cheap power since those very effienct gears don't require much energy to run.

My pick would be somewhere in between, 40-50w/th gears will do, maybe a second-hand M20s, uses 48w/th , does 70th and costs about 5k, you can probably squeeze in 4 of these, the total cost should be in the 22-23k range, hashrate is about 300th, that's about 3k per month, you should assume that the average income for the next 2 years (assuming the asic won't die on you) will be half of that, if the price does not collapse, the difficulty will double, so any expectation above 50% of the current numbers is somehow wishful thinking, so 1.5k a month.

But then you said:


Mining isn't really a very long term business, it's not something you can retire on, I mean in a few years a few halvings will cut the rewards into pieces and there is no guarantee that either the transactions or the price will compensate that, mining is really just investing in BTC using a different model than exchanging cash to bitcoin.

So my humble opinion is that nobody should count on mining for their retirement plan, health care, student loan repayment, or anything that has no room for error, mining is a very risky business, it should be treated as an opportunity to maximize your gains in the short to mid-term and nothing more than that.

You could potentially turn 60k into 120k in 1-2 years if everything plays out well, but will you be making 60k a year mining bitcoin for the rest of your life? most certainly not.

Not sure where you bough the tool from, but on Zesbtc they have a huge warning that says:


Source: https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=212

You said you have S17+ which is a "combined mining machine", so you might be careful when using an external PSU, as for instruction, zeusbtc has a truckload of pdf files, search around and you will find the manual for the fixture tool.  Good luck

Sounds like a language barrier or lack of understanding, I did not say that you mentioned anything about that, I was stating a general statement, perhaps the correct word is "someone" rather than "you".


Small pool should not shutdown just because they are small, but will I gamble my hard earnings on a small pool that does not find a block for a whole year? absolutely not, however, if someone is willing to do so they have the right to.


Their profile shows last active  "June 21, 2021", so instead of repeating the same statement here, you might want to reach out to them through a different platform since clearly, they don't seem to prioritize the forum.

If they ignore you or refuse to correct that word, you can take it up to the reputation board and see what the other DT members have to say, personally, I don't mind tagging thier profile, but since this isn't an urgent case of scam and nobody's life/money is at stake, I chose to be patient and wait for Slush's response.

مصدر USDT هوا نفسه في جميع المنصات, المنصة تقوم بطلب سيولة معينة, تقوم tether بطباعة - mint للعملة وترسلها للمنصة, هنا يفترض ان تكون المنصة او المشتري قد حول مبلغ مالي بالدولار ويجب على الشركة في المقابل ايداع ذلك المبلغ لتغطية القيمة السوقية ل usdt = 1usd وحتى في حال كانت الطباعة سابقة لطلب احد المنصات يجب على الشركة ايداع الرصيد بالدولار قبل طباعة مايقبالها من usdt ولكن الامر لايبدو هكدا ابدا.

في اخر تقرير قدمته الشركة "مرغمة" كان رصيد العملة من الدولار الكاش لايتجاوز 4% , وجزء كبير من الاوصل كان عبارة عن قروض وسندات امانة واوراق مالية بعضها عالي الخطورة, لايوجد اي مجال للشك بأن هده العملة لايوجد مقابلها 100% من الاصول وهدا واضح من خلال الاحداث على مر السنين وتهربهم من الافصاح عن الارصدة (التفاصيل كثيرة ولكن انا كنت اتابع الموضوع عن قرب) لذلك انصح بالابعتاد عنها.

اما للاخ صاحب الموضوع ان كنت تقوم بالتحويل لشخص داخل منصة باينانس يمكنك تحويل usdt على trc20 or bsc فالتحويل مجاني وحتى الخصم 1$ سوق يرجع لرصيدك في حال كان التحويل داخلي, شخصيا افضل استخدام busd فهيا رخيصة وموثوقة اكتر بكثير من usdt.

The details in the OP are not enough to troubleshoot the issue, you need to post screenshots and the kernel log, you should also mention the things you have tried, did you try a different PSU? control board? do the other hash boards work fine? the more details you provide the more likely we can help you troubleshoot your problem.

The kernel log you posted isn't complete, the fan check is the first stage, most issues happen after that, unless it's a fan issue whereby the kernel log will stop, but not the same way your kernel log looks like, so please post the whole thing.

Also, make sure you use the tag code, this post looks messy, it has to be like this.

It happens to all pools, it is not something a pool can escape, but then using the "block unit" is irrelevant as far as miner's payout is concerned, 300% on a large pool that finds 10 blocks a day is nothing like a 300% on a pool that finds 1 block a year, we all know the payout will eventually be the same if measured against infinity, but that can't happen in a real-world, personally,  I don't mind a 300% block once a day/week on a large pool as I know it will break even the next day/week, but waiting for a couple of years for that to happen isn't feasible, so no, you can't compare a small pool to a large one and say that mining here or there will yield the same payouts.

Of course, I don't think small pools must shut down, I believe miners know the risks beforehand, they also know the benefit of hitting a block on a small pool, so it's a risk they chose to take in return for a potentially larger payout.

I believe the APW12 is made of two PSUs each with AC input, looking inside the PSU everything is duplicated, it's like you take one PSU and mirror it, you can get more details here > https://www.zeusbtc.com/manuals/Antminer-APW12-Power-Supply-Repair-Guide.asp

I personally prefer Bitmain's way of powering the miner to Whatsminer that uses a single C19 input, unless someone is building the infrastructure from scratch it will be very difficult to deal with PSUs that need a large enough wiring/mcb that can handle 3500w, when I upgraded some of my S9s to S17 pros, the process was very easy, I have C13 power cords that can handle one S9 + some margin, 1 S9 consumption is nearly half of S17 pro's power consumption, all I needed was take two S9s power cords and plug them into one S17 pro.

Installing M21s was not as easy, luckily I oversized my wires from the MCB to the miners, imagine I used wires that could barely handle an S9? I would have to re-run wires from the MCB all over again to be able to power the M21s.

It's like asking someone what car to buy for 60k? when you ask the question as is, the answer will be of no benefit because nobody knows anything about your personal case, there are some factors that would determine the most suitable mining gear for every individual case, what is your power rate? how much capacity do you have? are you okay when used gears or not?

You need to list as many details as possible if you want an accurate answer.

That's not exactly true for all cases tho, there is always a chance that hash boards from different miners are compatible with one another, I had success in swapping hash boards from different miners without having to use custom firmware or touch the EPROM, also, if the reseller knows his stuff, he would probably program the dashboard before shipping it assuming he keeps a copy of the hex from the miner before sending it.

With that being said, if so happens that the dashboards are not compatible with one another, I think using custom firmware is easier and cheaper than going the other route.

There is no shut down button on these miners, the normal way to shut them down is by cutting the power, so it makes no difference if you unplug the power cord manually or kill the breaker.

Once the power is back they will go back to mining without any manual steps needed, now wether the continuous off and on will reduce the lifespan of these gears or not is a another different topic.

Using some custom firmware you can "pause" mining, but the miner will still consume some power for the fans, LEDs and what not, the best solution IMO would be using a wifi-MCB which you can control using an app on your phone, it should be available in Germany, if not, get those little "WiFi Wireless Smart Switch", however, these are not rated for high power draw, so you will need to connect them to a relay/contactor that controls the circuit breaker/s.

So the app sends the signal to the switch, the switch sends the signal to the relay/contactor, the contactor kills the MCB > the miners are shut down.


No such thing as algo change, bitcoin mining has always been sha256, the difficulty grows higher and so the amount of btc the same asic miner can generate becomes less as time passes.


Yes, use www.whattomine.com, an S9 at 14th makes 4.2$ as of today's prices, and it requires 1.25kw, so in theory, every hour it makes 17 cents, as opposed to you selling the 1.25khw for 7*1.25 which is 8.7 cents, but then you need to take into account the cost of the mining gear.

The main problem I see here is that using only surpluses of your solar system means you can't use a single miner, the 10 or 30 khw you get are spread throughout the day, so if you use 1 Antminer S9 and want to drain those 30Khw, they need to last for 24hrs, which of course, won't happen.

So what you really need to do is not only count the amount of extra power you generate but the average daily duration, if the surplus of 30kWh lasts for only 3 hours, it means you will have to consume 10kw every hour, which means you will need 8 S9s and not just one.

of course, you can always just use what you can and sell the rest to the grid, but then, to ROI on that single machine it will take forever and you could be better off just sending that power to the grid.

So you need to do the math,  I believe you can get an S9 for $500, so you might run the numbers based on just that and see if it makes sense.

You are lucky, the seller seems to be honest, most sellers will just tell you "the miner was working great when we shipped it", hopefully, they will send you a working dashboard, although I'd prefer if you got a 1/3 refund instead, but still, a lot better than nothing.

where are you located? the bad hashboard could likely be fixed, and since it's reporting 64 Asics out of 65 it means likely that the 63-64th chip is bad due to bad connectivity, here are two things to try

1- Locate those two chips, you can do see by reading this > https://www.zeusbtc.com/articles/information/182-antminer-s17-manual-download, apply some serious pressure on both for a while and then test the hashboard.

2- Put the hashboard in a plastic bag then seal it, put it in the freezer for 24-48 hours and then test it.

You will Likely be able to get this to work, but i don't understand the ranges you are talking about, can you post the datasheet of the generator you have?

At least 9 out of 10 houses on planet earth have 220 or 240v in any socket attached to the wall, so they just plug the end of the power cord and off to the races.

A few countries like the U.S use 120v and thus people will be limited to old gears that support 120v or they hire someone to set up a 220v line for them if possible.

Again.. you need 220 to 240 to run most miners, anything outside of that range will either cause you issues or in most cases just won't work.

They are called Asic Miners, Antminer is just one brand by Bitmain which is the largest manufacturer, what is the exact power rate you have? total power capacity? space? is noise a problem? 3k Euros can get you 1 gear and can get you 10 gears, it will depend on the points I mentioned above.

Try to flash the stock firmware as mentioned above, but it will be highly unlikely that it will fix anything, the problem is here


You will need to unplug Chain 1 which is the middle chain ( if the miner has not been tampered with) but should be easy to identify, that will most likely fix the problem. and then how to fix that bad hash board is a whole different topic on its own.

These U.S voltage ranges are as complicated as it gets, at least judging by how simple things are over here, but then the power laws are universal, which means the part quoted above is most likely WRONG!, at least the last part of it.

Higher voltage does mean fewer amps, but "current" aka amp unit here does not even matter. Regardless of the voltage power = power, your generator is rated by KVA for simplicity KVA is KW not accounting for the power factor.

So in other words, if your generator is rated at 100KVA, it will be able to output 80KW worth of power, if put at 220v then it translates to "363 amps", if it's at 110v then you times that by two and it becomes "726 amps" but that does NOT mean your generator magically generates more power at a lower voltage because 80KW is 80KW be at 220V or even 12V is irrelevant to the case in hand.


 I can't seem to understand the mess in these voltage ranges, but to give you a clue based on power generators where I live, there are two types of them.

1- Single-phase 220v (1L 1N), you get it as is, if it says 100KVA you get 100KVA from N and  L.

2- Three-Phase 380v (3L, 1N), you get 380v from every 2 L lines and 220v from every L and N, but then every phase (L and N) will be capped by 1/3 of the total capacity of the generator, so if you need to use the 3 phase generator on single-phase devices, you will end up with 3 outputs each is L and N and you must balance the load between them all since that could be a bit hard to achieve some people chose to change the connection and get single-phase output from the generator by sacrificing 1/3 of the KVA, which means changing 99KVA 3 phase gen to a single-phase will give you a max of 66KVA between 1 L and N.

Long story short, is that the VAST MAJORITY of miners need a SINGLE phase 220-240v, so discuss with your selection on the best setup to achieve this, also there are two members here who are really good in this field : NotFuzzyWarm and HagssFIN). hopefully they will chime in and give you some advice.
