We dropped


It does seem like some miners can't do with current prices which is great news, I am not expecting a drop by any means, but not going up much is probably all that I could hope for from now on.


I am afraid the cost of the mining gear will be higher than or equal to the tax reduction you get, I highly doubt Bitmain can afford to sell you the same gear for the same price outside of China, the 10k gear in China will most likely cost them more to make which will be enough to offset the tax thing, moving outside of China won't make mining gears Cheaper in the U.S, it will just make them more expensive for the rest of the world.

I'd say 99.99% NO.

This chain does not detect complete asic count at the first test, which likely means there is an issue with Chain 0, it drops a while after the miner starts hashing, this, however, could be a PSU issue, can you post screenshots of the miner status page?

That is not always the case, the voltage stored in the EPROM could be the same and it will work just fine, some miners like the S9k had the type ID printed on the hash board itself, some of the S17 series have the type id in the kernel log, so the seller can pre-program the dashboard before shipping it.

---

OP, the most component of the miner that fails is the hash board, it's very hard to find hash boards of very old miners like the S9s, it will be extremely difficult to find any for S19 pros, even if you do, the price will likely be way too high, not telling you to dismiss the idea, but keep your expectations as low as you can afford.

Keep in mind that these hash boards are sensitive, it will be very hard to ship them securely, it's always best to buy a hole miner and use its component as spare parts, but this of course only makes sense if you have a few miners and not just one.

Plan B would be to send them for repair, which will most certainly be a lot cheaper than obtaining a replacement hashboard.

Who is he going to sue exactly? there are a dozen of folks who do that, most with no known real identity, the resources needed to secure such an open-source code are far more than what Kano or anyone else can afford.

In fact, even the devs who have more skin in the game like Jeff Garzik who wrote the cpuminer code or CK who then forked cpuminer to Cgminer, and despite that fact that he is the major dev in this and if I am not mistaken Cgminer functioned for a while before Kano touched the project, the latter seems to be the ONLY person who cares about this.

Even the other devs likes luke-jr don't seem to care, almost all of the major devs who contributed to the project one way or the other are now successful millionaires who probably don't even know about the existence of these custom firmware in the first place.

While Kano isn't doing anything wrong by "chasing" those who violate the license of the a code he heavily participated in, it's just sad that he does not have anything better to offer for the community other than nagging about people breaking the license which is no matter how you look it at is just a waste of time judging by the fact that the custom firmware market is only growing, but well, it is what it is.



Because the forum is not a court of law, it does not even moderate scam, you can literally create a topic saying you are a scammer and you are planning to scam someone and the mods will most likely not delete it (unless it breaks one of the rules which scam isn't one of them) let alone topics that violate a certain license, the forum will not project the license on your behalf, also,  nagging about it here will change NOTHING, if you want to stop all these folks from making money off your code, stop nagging and start coding, add the auto-tune part and let the users use your free version, at that point, nobody will be using those custom firmware that take 2-4% fees.

If you take the above seriously and do decide to start coding the cgminer again, I am sure the miners' community will fund the development, I will be the first person to donate and will help you spread the word to get enough donations to keep you going.




 

The level of fluctuation you talked about is not usual but it really does not matter at all, your average accepted hashrate is all that matters as far as your payout is concerned, so if your daily or 12 hours hashrate is within -+1 to -+2% of the hashrate you see on the miner status page - everything is just fine and the fluctuation should be ignored, if your average hashrate on the long run also fluctuates as much then you that means something is wrong somewhere.

I don't have anything against this "theory", in fact, I do tend to believe that it makes a lot of sense, however, I have a few S9s that have been mining like a beast for about 4 years, those gears are turned off and on at least once a day, sometimes 3-4 times a day, and they are treated like shit, up to this point, zero issues. On the other hand, I had some S17 series gears treated very well, not much off/on, very good cooling setups, and they died in no time.

So really it all boils down to the quality of the miner, if the gear is already bad as is, I'd imagine that turning it off and on more often could speed up the failure process, but if the gear is rock solid, I highly doubt it will kill it before it becomes unprofitable to mine anyway.

It's probably not, I know many people in UAE, none of them is hardly named Donny , jokes aside, with all honesty, I believe this is nothing but a scam attempt, I can't tell you how I arrived at this conclusion (for security purposes but being in this mess long enough, I have good reasons to believe that this guy is not legit at all).

With that said, if you are interested in "investing" with him, please don't unless you are in Dubai and have seen the facilities and gears, that will at least reduce your chances of getting scammed.

I tried to use all the imagination I can afford and honestly I can't see how your control board will damage the fans, the miner's fan isn't some sort of a sophisticated piece of electronics where a dozen of things can go wrong with it, it is just a .. fan.  So I still suspect it's the air pressure that causes this increase fan failure, before you fix it, there isn't much you need to troubleshoot, not even the quality of the fans.


Where do you see that on the pool status page or the miner itself? hash variance on the pool is pretty normal, on your miner status page, it's a lot less noticeable, however, seeing 50th and 250th from a mining gear that puts on 95th on average is somehow very strange, I have seen my M20s does 80th instead of 64th, sometimes 55th, but nothing close to 50% or 200% as you explain, it certainly is strange.

The hashrate variance is probably caused by a bug on antpool, maybe the difficulty code isn't right, or maybe some issues with the miner itself, but really, before pointing your gears to a proper pool -- it's hard to tell where the problem could be, so if you want PPS+ pool, try Viabtc (i personally use it), it has a bit higher fees than most other PPS+ pools, but to me, it's worth every satoshi.

My guess is that nothing is going to change for Bitmain and the other mining manufacturers, they might stop accepting crypto payments to comply with the new regulations, but I highly doubt that they will be forced to leave China, the Chinese government only has a problem with crypto and mining, I don't see why would they want to shut down mining gears manufacturers that feed tens of thousands of Chinese.

But if what you think actually ends up happening, it will be good for the difficulty I suppose, the making of these gears anywhere outside of China mainland will without a doubt make them a lot more expensive.

As for burn-in, maybe they can use a bogus Bitcoin address such as "1BitcoinEaterAddressDontSendf59kuE" and they will rest assured that nobody can spend it.

A few hours before the news from China when BTC was at 44k, the pace was positive it was at about 101.5%, right now it's 99% flat, could be "luck doing it's thing" but I am leaning towards the fact that price drives those mining profiles as explained in my previous post.



Used gears prices in China fell by a tiny percentage in the past few weeks, nothing major, I believe this is based on the fact that right after the mining ban prices dipped a lot for a short while due to the increase in supply, and then in a few weeks prices started to rise due to demand, this crazy shift in the ratio of demand-supply ratio made the level of impact of bitcoin price on mining gears a lot less.

Usually, gear prices are determined by profitability,  lower diff / higher bitcoin prices = increase in gear prices, the exact opposite is also true, but recently due to the ban, you will find that gear prices go up with profitability going down or the opposite, so it will take a while for things to settle and go back to normal.

Same here, since (as you are probably already aware) that power rate isn't a problem for me, I only play with those numbers for cooling purposes, but if I had to pay a large bill then making my gears 20-30% more effienct when prices are just not right - will most certainly be something that I do on daily bases (automatically), also add to that the fact that smart mining pools like Viabtc give you the option to convert your payouts to a stable coin automatically, so this combined with the auto-switching becomes a great tool for managing your gears this way.

An S17+ can do 80th at 3160w (40w/th) and it can do 52th at 1700w (32w/th), the effienct profile is 20% more effienct, while the beast mode gives you 50% more hashrate, if we assume that 20-30% of mining gears are switching between similar profiles, then it won't be surprising to see huge immediate shifts in hashrate as the price moves up/down

Can't speak about the other 3 epochs, but for this one, I tend to believe that the 10% price increase had a major effect on this, 2 days ago when the price was at 39k-40k the pace was well before 96 (I believe it was at 91) and then it started rising as the price kept moving up, which means there is a good possibility that many miners are mining at the edge of being profitable.

The other possible scenario which is more likely would be the automated overclocking/underclocking, with all the available tools today, miners can set their miners to mine at say 70w/th when prices is above x, and then drop to 50w/th when the price is below x (the latter will result in a less hash rate), the over/underclocking effect is real, personally, I have just about 15% of my total hashrate setting on the sidelines waiting for mid-October, those will come online with exactly 3 clicks.

For viabtc, the above points are likely less worthy of any consideration, but the point you mentioned here is key


I have noticed and warned about this subject back in November 2020, Viabtc will only allow you to point those contracts to their PPS+ pool, which is more than clear that Viabtc does not really own any mining gears, they will simply collect cash from you and give you bitcoin based on the theoretical income of that imaginary hashrate you pay for, so once the contact starts generating a lot more than what you pay, I don't see what stops Viabtc from rejecting to pay you anything.

Given that they are a well-built company, they won't just scam you, they will probably offer you a refund and maybe some kind of bonus on top and tell you "sorry our mining facilities were shut down by the government" or any other excuse, they could be honest and bear the loses, but I highly doubt that they will pay you a 100$ in BTC in return for say for an example the $20 you pay them, this is just a high risk that I certainly wouldn't want to take under any circumstances.

That is a possibility. however, I have personally used some very cheap fans on my gears and they don't die anywhere close to the rate OP is talking about, this is likely a combination of bad quality and some other issues.

OP, what is the design of your farm? pressure plays a major role when it comes to the lifespan of these fans, I remember before fixing the pressure in the farm we were losing fans a lot more often than we do now, ever since we controlled the air pressure we seldom lose fans despite the fact that we run most of them at a constant speed of 90% where temps are usually a lot hotter than your temps.

Why does anyone else hide their code then? why can't everyone just publish their code and the whole world becomes a nice little happy place? just because they hide the code does not necessarily mean they are doing something bad, they could be doing that so other folks can't use/sell it for free.

OP, none of the "trustworthy" custom firmware have the option you are looking for, it's safer and better for them to just charge you the fees by using your miner to mine to their pool, I don't see why would anyone offer a one time payment which is a lot harder to maintain.

There are a few factors involved, nothing I say or think is worth anything for that matter, in other words, you can't take any of it to the bank, what I know and have been saying for years is that difficulty will ONLY go up regardless of what the price does, of course, I am not talking about the short term drops that happen within a month or so, I am simply stating that the average difficulty this year will without a doubt be less than that of next year.

The second most important factor to most folks would be the price of bitcoin, while price tends to go up in the very long term, there is no guarantee that it will go up within the period of the contract, plus, notice why I said "to most folks" because, to me, price does not matter, simply based on the fact that if you are certain that price will go up, why not just buy bitcoin instead of those mining contracts?


The whole purpose of mining be it cloud mining or actual mining is to make more BTC than what you can buy directly, if not, why even bother? of course, there is always a chance that you will end up making more BTC buying those contracts, but then, so many stars have to be aligned for that to happen, chances are, most folks won't be making more BTC than what they could otherwise buy directly.

The recent difficulty drop caused by the mess in China was probably the only reason why buying those contracts a few months back was a good move, but I won't be counting on that to happen again.

The majority of cloud mining companies are nothing but scam, the rest are overpriced, Viabtc offers a legit cloud mining service, I have not tried it but I use viabtc for mining and they are indeed trusted so it's highly unlikely that such a large pool will turn out to be selling scam mining contracts.

Also, IIRC bitdeer has a partnership with Bitmain which makes them somehow trustworthy, but again, the legit ones are overpriced, the fake ones are just ... fake.

انا لا انصح اي شخص بتحميل هده البرامج فهيا في اسواء الاحوال تكون اداة لاختراق حساباتك والوصول لملفاتك وحاجياتك الشخصية وبيعها لمن يدفع مقابلها سواء شركات الدعاية او غيرها, وفي احسن الاحوال هده البرامج هي مضيعة للوقت وتقوم باستخدام هاتفك في اشياء اخرى عكس التي تصرح به.

هل اجزم انك لن تتحصل علي اي مكسب من مثل هده البرامج؟ بكل تأكيد لا, ولكن هل ستتحصل على مبلغ يبرر الوقت والمخاطرة المرتبطة بتحميل مثل هده البرمجيات؟  على الاغلب لا.

الامر نسبي, مثلا معظم حملات التوقيع في المنتدى تدفع مثل هدا المبلغ وبعضها يدفع هدا المبلغ اسبوعيا, وبضعها يدفع ضعف هدا المبلغ اسبوعيا, يعني ان التركيز على بناء حسابك في المنتدى (وهده واحدة من عدة اشياء اخرى) دخلها افضل بكثير, اعرف ايضا بعض الاصدقاء يجنون مبالغ اكبر من هده بكثير عبر وضع روابط احالة لمنصات في شروحات على اليوتيوب والفيسبوك و غيرها, اعذرني على استخدام مصطلح "مضيعة للوقت" ربما كان الاجدر ان اقول ( هنالك بدائل قد تأتيك بعائد افضل) وعلى العموم اعتذر عن التطرق لهده النقطة من الاساس.
