This is what the difficulty is all about it, technology is irrelevant to the supply of bitcoin, the more advance it gets - the harder solving the blocks will become, so be it a fancy quantum computer made by a unicorn outside of our Milky way or a bunch of kids solving the blocks using a pencil and a paper, the new-supply will remain more or less the same.

And since the "speed" of finding blocks is almost constant (10 mins to each block), the reward halvings cause the deflation of the new supply, the keyword to your question here is (deflation).

Now that we got that out of the way, let's do a bit of math

In the first 4 years (it's based on blocks but let's just say 4 years for simplicity) every 10 mins 50BTC was created, so every day 144 blocks each have 50 BTC was created, so that was 7,200 BTC a day, or 216,000 BTC a month.

Today after going from 50>25>12.5>6.25BTC the block reward now is 6.25BTC, so as opposed to creating 7,200 BTC a day, we only make 6.25*144 = 900 BTC a day, in the next halving we will only be able to create half the amount, eventually it will take months to generate 1 bitcoin and then months to create a fraction of bitcoin.

Or he could use something like Vnish and use the "chip frequency settings" to lower the frequency of the bad chip to the lowest point possible, that way the rest of the chips will run at the default frequency and he won't need any hardware modifications.

doesn't the fact that about 150EH worth of hashrate is mining bitcoin suggest that it's profitable? everyone who mines bitcoin using proper gear ends up making a profit but is it a net profit or not is what you should be asking, the other question which you should ask is whether there is something else to invest your money in which would yield more profit than mining, for an example, directly buying bitcoin.



IMO, it's not worth it, there is a minimum amount of work that needs to be done, also some down payment for the infrastructure, and of course failure rate which is very high with most bitcoin mining gears, having 1-3 mining gears is not feasible any more IMO, anything below 300-500th is going to be a waste of time, personally and after having gone through much trouble with mining gears, electricity, set up and all that, I can't do anything less than 1PH, I just think it's not worth effort.

I see you created another thread just for this problem, which IMO isn't needed at all, in my last post I asked you to set fans to full RPMs using static fan speed of 100%, and then to report back on the finding, you said you flashed bitmain firmware but you didn't mention anything about the fan speed.

اجريت حديث مع احد الاصدقاء بخصوص تأثير الكم الهائل من العملات الجديدة الموجودة على بلوك تشين باينانس او ايثييريوم او حتى  الجديدة منها التي سوف يتم انشائها على منصات اخرى, السؤال هوا, هل تعتقد ان 1_تأتيرها سلبي على السعر بحيث ان تلك الاموال التي تدهب لتلك العملات كان سيتم استثمارها في البتكوين ام
2_ان تلك العملات لديها تأثير ايجابي حيث انها تساعد في انتشار الكريبتو وجزء من تلك الاموال سيجد طريقه للبتكوين.


ارجو اختيار احد الاجابات مع وضع شرح (بسيط او مفصل) لسبب اختيارك.

Pool mining is the only feasible profitable way to mine bitcoin, even if you invest millions of dollars in gears you are unlikely to make a steady profit mining alone, the network hashrate has grown too huge for a single entity to mine solo, let alone a single person.

With that being said, you should also know that the size of the pool is very important, small pools that don't pay in PPS are more like solo mining than pool mining, your rewards will vary greatly and you might not even get a single reward for the life span of your mining gear.

بدون الدخول في اي تفاصيل معقدة, لايمكن باي حال من الاحوال تعدين البتكوين بدون استخدام اجهزة ASIC المخصصة للتعدين, وكل هده الاجهزة تأتي محملة مجاني ببرنامج تشغيل مبني على Cgminer وهيا جاهزة للتعدين مباشرة بدون الحاجة لاستخدام اي برنامج اخر, اي طريقة اخرى للتعدين فهي اما نصب او مضيعة للوقت او الاتنين معا.

Not that any other cooling method is needed to cool these S9s since they run relatively cool in the worst climate, but if you insist on doing so, you should go for immersion cooling, let those hash boards swim in the non-conductive liquid, and you won't have to worry about shorting the chips.

How is that relevant? are you saying that since Bitmain is in China they don't have to comply with the gpl3 license and thus the firmware on bitcoin.com is LEGAL, but the one on BTC.com (which is also made the former) is ILLEGAL because their HQ is in Amsterdam?

The wattage is the actual draw when the miner works at factory mode with no overclocking/underclocking, it starts at 1-2w and then slowly climb to 3250w +/-, the PSU can handle a bit more than that, and of course, if you happen to underclock it will consume less wattage.


The ideal is 24/7, but we have a lot of power outages where I run the miners, I don't think that creates any major issues, although some people claim that this will negatively affect the miners, I tend to believe that is far from accurate, assuming when the power comes back the voltage isn't super high/low enough to damage the PSUs.


There are two main types of mining payouts, one is PPLNS and another is PPS, the latter stands for "pay per share", it doesn't matter how many time you connect and disconnect every single (valid) share you submit is going to be paid for, the former is a bit more complicated and every pool has a different N value in it, but in general, the power outages or network issues will have an impact on your earnings. if the pool is small and they hardly find blocks you could lose months of mining if your gear goes offline when a block is found, so if your hashrate isn't dead stable, you might want to use a PPS pool.



The ideal room temp can be found on the specs of the miner, basically 20c to 40c is ok, liquid cooling is costly and it's not needed, just make sure you move enough air and your gears will mine just fine.

Over the course of 3 years, I helped countless people troubleshoot and fix their mining gears, some folks here have been around years before me, most are helping out for free, there is absolutely no reason to incentivize the fine gentlemen here with money.

Just to confirm that you are not doing something wrong, please show me the files you used to flash the miner, and where did you download them from? also, what was the size of your Sdcard.

in order to troubleshoot your issue more accurately, we need to confirm that you did indeed Sdcard the control board correctly, sadly most people don't. , also, do you happen to have another miner or this is the only one you got?



That's good advice, but his gear is nowhere to be found on the network, how do you expect him to install the firmware when the control board is defective?

Allow me to quote you Mr.Kano



You also pointed OP to download the bitmain firmware from bitmain.com, and they happen to be the same people who make the firmware you now call illegal, do you have a weak memory or are you a hyprocate?

let me quote you one more time




So when ck talks about bitmain violation for Cgminer he is bullshitting, and Bitmain is a great and honest company that doesn't need to



Just because you dislike CK more than you dislike Bitmain, it's OKAY for bitmain to do that, and then now in this thread, you are calling BTC.com firmware which is Bitmain's official's firmware "illegal", lol, I understand that you didn't even read the topic, you missed the point that this firmware is Bitmain's so you called it "illegal", I suggest the next time your fingers get itchy and you just want to post, at least google the topic so you don't embarrass yourself.
 

A simple question.

Is bitmain firmware legal or illegal?

Ok so the summary is

Chain 0 finds 65 asic but has a problem with the temp sensor
chain 1 finds 0 asic
chain 2 works just fine

Can you make sure that all the PSU screws going into the hash boards are tightened? also, check the ribbon cables from the control board to the 3 hash boards, swap the ribbon cable from chain 2 to the other two hash boards to confirm the problem isn't the cable.

You also seem to have a network related problem

Try using a different network cable to troubleshoot this matter.

That was my initial guess, but I had to dig a little further, the explosion was very serious, it killed 12 people and about 20 miners are trapped, and this was not the first explosion this year, this seems to have led the authorities to want to investigate the matter.


So while the explosion did not cause a black-out in the entire Xinjiang region, it did cause a major shutdown in most coal power stations, as the same article reads:





hashnets's farm is also located in Xinjiang and so it has no power to operate, and they won't have it until the "inspection" on coal-based plants is over and they are given the green light to turn them back on.

I thought that by now everyone and their grandmother have heard about the coal mine explosion in China, a detailed explanation which I posted in the uncensored difficulty topic can be found here:

The firmware you have installed is not illegal unlike what some people claim, it was made by "Bitmain firmware development team" alongside BTC.com team, the BTC.com probably had little to no coding invested in this firmware, BTC.com wanted to attract more users to its pool, so they asked Bitmain team to customize the official firmware with a bit of overclocking/underclocking capabilities, they give it for free but of course it has to be used on their pool.

Since Bitmain is known for locking their firmware, this one had to be "for obvious reasons" locked too, and since it came later than all the original firmware on their own website, you simply can't revert it, so you will have to Sdcard your way in.

Can you try this firmare (Antminer-S9i-xilinx-201907302056-autofreq-user-Update2UBI-NF-sig.tar.gz) you can download it here https://service.bitmain.com/support/download?product=Antminer%20S9i

Keep in mind this is a secured firmware, which means if you want to go back to custom firmware you will need to use an Sdcard.

But that does not solve his problem, he will still need to pay 0.0005BTC when he wants to withdraw, with his gear making about 50 cents a day he needs to mine for 53 days just to cover the fees.


If he has to use a custodial wallet then why go as far as moving the funds to Binance exchange, eventually, he will have to withdraw and be hit by a huge fee, Binance is by no means more trustworthy than any large BTC mining pool, he could just keep his funds in Viabtc until he reaches the minimum payout of 0.001BTC and they get transferred to his own wallet at 0 fees and as a single output, if he wants to use Binance pool then simply apply the same thing, leave the funds on the mining pool until they are eligible for a fee-less payout, in all cases, moving the funds to an exchange just to withdraw them later at a high fee is a bad move.

That's based on your personal opinion I suppose? Just double-checking on the subject because the price is right about "fair", here an updated list from one of my suppliers in China.

       

it is extremely unlikely to find cheaper prices than the list above, of course, there should a bit of variance between resellers based on the quality of the miners and the quantity,

I would most certainly not pay that much for such gear, but it's what it's, 10.5k for second-hand S19 is right about "fair" based on the current market conditions which are mainly driven by greed and newbies jumping into the game at the worst time ever IMO.                          

The late 2018-2019 drop in difficulty was very short-lived and it wasn't even a fraction of the drop in price, you are totally right about difficulty not being on a vertical uptrend where it only goes up every 2016 blocks but it's it goes up as opposed of down at leats 90% of the time, and until something major happens to this industry the safest bet would be "up", if you randomly bet 10 times on 10 future epochs you will most likely end up winning big.

I have to agree with Kano although I seldom do, ROI should be based purely on BTC, if you can't get the BTC amount you spent, just save yourself the trouble and buy the coin, especially given the fact that more often than not gears lose their value over time and are subject to die at any second (ignoring the crazy times we are seeing now because of the global chip shortage).

With that being said, those who place everything based on fiat are not doing anything wrong, you invest $1000 and you want to earn back $1000 + profit regardless of where bitcoin goes or what happens to it, that's completely fine, the problem with this approach, however, is the fact that your fiat profit will ENTIELRY depend on the price of bitcoin throughout the period you mine, which forces you to look back at the BTC valuation even if you think BTC value is irrevent.

I personally use the term ROI and attach it for fiat for simplicity purposes, but personally, if it does not make sense BTC wise, I rather store the coin safe and sound than going through all the troubles with mining.
