The default packet size in Linux is 64 bytes (actually more like 58 bytes + 8 bytes for ICMP header) whereas on windows it's 32 bytes, you can actually specific the ping packet size by doing

This sends 32 bytes


This sends 128 bytes

Your transaction was mined on (19, 2022 at 4:58 PM GMT+2) I posted the above on ( 18, 2022, 03:44:29 AM GMT +2) my prediction was a few hours off, but not too bad.

Anyway, glad it's over, make sure you use a proper wallet from now on so that you won't have to go through this again, visit the wallet section of this forum to see all the good options.

Ignore the dollar value of the fee, focus on sats per vbytes , you pay fees based on the size of your transaction, but since there is a limited block size, all that matters is how much you are willing to pay for every byte you use in that block, OP just so happened to be pretty unlucky because on the 13th ( a day before he broadcasted his transaction) the mempool size ( there is actually no "THE" in mempool but for sake of simplicity) was at an average of 2MB, the average bitcoin transaction is about 250 bytes so roughly 8000 transaction at any given time during that period, so supply is 1MB vs demand of 2MB as an average, in fact in some hours, there were fewer transactions than the block could fill, so miners would happily accept any transaction at the cheapest possible fee.

Fast forward the mempool size reached nearly 138MB on the 15th (most likely due to FTX crash, these black swans cause people to transact a lot, either those running away and selling or those who just bought what they call the dip, or those withdrawing their coins from exchanges to safer place).

Now since there is way more stuck transaction than the miners can handle, people are willing to pay them more, as I type I randomly checked and saw some transaction right now are paying over 140 sats per Vbyte vs 4 sats OP is paying, so he is going to have to wait until miners run out of those "expensive" transactions and then they will include his transaction.

The mempool is getting smaller and smaller as I type, and it's likely to shrink even more around Friday night then the 4 sat/vbyte transactions will become attractive again and his transaction will go through, if I had to throw a number at the wall I'd say 30 hours from writing this comment.

However, there is really no guarantee on how long one might need to wait, imagine for whatever reason people wake up tomorrow and decide to use bitcoin for daily payments and the average sat/vbyte doesn't drop below 10 sats, this transaction could be stuck forever  , of course, that's extremely unlikely to happen but one should always use a wallet that allows them to react when something like this happens if OP has access to the PKs he could just use another wallet to broadcast the transaction again at higher fees, or -- he could just wait till the weekend.

Sadly, no one here can help you with that, while most of us here are miners, we don't get to choose which transaction to include the blocks, the mining pool itself does and since your wallet options are limited and you can't do RBF or anything else, there is almost nothing you can do about it, I checked your transition fee and it's 0.00000559 BTC it means even the free accelerator like Viabtc won't accept it, paid services will cost a lot (i think 30-50$ with of BTC).

You paid almost 4 sat per vbyte which isn't the worst in the world, should go through in the weekend.

While the numbers shown there look good, these companies always hide the important figures, they tell you they made $20M in Q3 of 2022 but they don't tell you about the fact that they bought an S19  for 10k and it still a few years away from ROI and chances are, it will never get there, I mean, of course, anyone who owns a mining gear is generating income  in fact, actually generating net profit when you ignore the cost of mining gears, building, infrastructure, and debt owed to others.

But all these companies try to do is show you the good news so they can sell their shares at higher prices on the stock market, they can fake these numbers for years, but when shit hits the fan, they will fall in a single day just like FTX did.



     

The pace right now is 100.56% at block 1228.

I saw someone sell the same model (S19 pro 100th) in the U.S for $1900, isn't that nearly the same as buying it directly from Bitmain even with the coupon discount you may get? I think these guys were given coupons so they managed to grab the gears for cheap, and the possibility they did the tax trick by declaring low amount, I don't know about you but if I had gears that sell locally at $1900 or even $2000 I would rather buy it than going through Bitmain.

Looking at the archived link the Nfish posted above, they mention this


So it seems like they only give coupons to those who have already bought any of the Pro versions at a higher price before the drop to 19$/th, are you eligible?

The next point is this


Did you sign the delivery confirmation?

These rules are new, they used to give out coupons without all these conditions, it's terrible of them to hide all these terms under a bold statement that says


Bitmain folks are doing what Bitmain folks do.

الامر بكل صراحة اصبح مخيف للغاية, والاسواء من كل هده الاحداث هوا خبر تجميد رصيد USDT الموجود في عنوان تملكه FTX على شبكة TRON بطلب من السلطات الامريكية, هدا الخبر اعتقد هوا الاسواء نظرا لان الحديث السائد بين الناس الان هوا ان الكريبتو ليست لامركزية والدليل هوا تجميد رصيد موجود على منصة باردة, الشخص العادي لن يفهم الفرق بين USDT ك توكن TRC20 وبتكوين موجودة على بلوكتشين البتكوين الاساسي في نظره انه لافرق بين وضع الاموال في المنصات او المحافظ فكلها معرضة للتجميد والسرقة.

على الصعيد الشخصي, فانا لم اثق يوما في اي عملة مشفرة ثقة كبيرة باستتناء البتكوين, طالما هي موجود في محفظة امتلكها, طبعا هدا لايعني اني لاستخدم المنصات او العملات المستقرة مثل USDT, USDC وغيرها ولكن استخدامي لها محدود جدا بمالغ بسيطة ان خسرتها يمكن ان احزن عليها يوم او يومين وانساها, فيما عدا ذلك افضل ان تبقى البتكوين في محفطتي واشاهدها تفقد قيمتها مؤقثا على وضعها في منصات يتملكها بش نصابون لايخافو من شي, اعتقد ان الصفعة القادمة ستكون ل USDT او Binance.

ايضا كل هده الاخبار السلبية هي مؤشر جيد على قرب انتهاء السوق الهابط, فكلما زادت المشاكل يعني ان الهبوط يقارب على الانتهاء والعكس طبعا صحيح.

Would be great if you could post more details and/or pictures showing how you did that, I am also curious if you did ask BO+ support for help, that firmware seems to be full of features, I wouldn't be surprised if they had that already built-in and just needs some sort of activation via CLI since there is nothing in GUI for that feature.

What do you mean by direct connection? You need access to the miner itself or you would just give us your pool and worker details?

I can spare 1ph if

1- I get paid in advance.
2- The rate is worth it.

In most cases and for most people, simply buying bitcoin is always better, but to answer your question, your backyard is a lot safer than any hosting company.

It is pretty known the most hosting companies are just scammers or rekless, even the most famous ones can get you rekt, you can search compass mining and how they screwed with their clients, in Russia and now recently Canada.

Hosting your miner somewhere you don't own is like keeping your crypto on an exchange, while that gives you more features and less fees, there is always a huge risk of losing everything.

Pace was 104% two days ago, we are not getting close to 100%, seems like the price drop has finally started affecting difficulty, hopefully we get a small drop this epoch and a largee one on the next if BTC price stays below 18k.

I have been trying to avoid thinking about this, but what the market feels like today seems like it's 2018 all over again.

We had the 6k level which we did not break until 11-11-2018 , the 18-19k level of this year broke on 8-11-2022 (pretty close), so if this would repeat what do we expect in terms of difficulty?

At the 6k break, BTC diff was at 7.18T.

Next epoch > 6.6t

then 5.6t

then 5.1t on 19-12-2018 which marked the bottom of the difficulty correction with a total drop of nearly 29% vs 50% drop in price, so with a ratio of nearly 1:2, so for every 10% drop in price, we would expect 5% in difficulty so 10k BTC should result in a 25% difficulty drop, 15k would result in 12.5% difficulty drop, it would be great to watch this unfold before our eyes, I love it when history repeats itself.

Phill, Scott said he used to distibute their products but not anymore, i asked him if they were legit he said yes.

He can still help out in sourcing and instaltion, hit me up on telegram if you still use it.

Ya, that's the issue with these miners, they put way too many chips in them, and clock them pretty close to their max so they would only run pretty cool when temps are acceptable, but then depending on where you put your miner, there would be at least a few weeks of pretty hot weather, it makes no sense to spend tens of thousands of dollars on cooling the farm based on a temp of 40c when that 40c only happens for a few weeks.

To solve that issue you can do

1- Shut down your miners when the outside temp is high.
2- Spend thousands of dollars on cooling which you won't be using for the majority of the year.
3- Underclock your miners when it's too hot, so they are not totally off and they are not running hot, and you have not spent a huge amount of money on cooling that you won't use when the summer is over.

It's pretty obvious that the last option is the best option, the custom firmware folks understand the need for such flexibility, they also know that people will rather pay them 2-3% of their hashrate than turn the miner off, they also know that in most cases that 2-3% is much less investing in more cooling, Bitmain did make a someone good firmware for the S9s back then, you could change the hashrate by -+ 1-2 terahash, your use the "Low-Power-Mode" which cuts about 5th out of the default 14th, okay not as rich in functions as custom firmware but was good enough for many people.

Starting from the 15 series onwards, they stopped doing that, and then they made the WORST miner series ever (The 17 Series) which is when custom firmware started to spread pretty fast because many people needed to underclock those crappy miners or mix and match hash boards, I still remember how unpopular the various custom firmware was before the end of 2019, their telegram channels had a few hundred users at most, some probably had no more than a 100, next thing you know, thousands of people became interested in custom firmware, I was expecting Bitmain would do something about it, but they didn't seem to bother.

air cooled mining farms probably make up more than 90% of the total mining industry, we manage to maintain acceptable temps even around June-July when temps go as high as 40c+, it's all about moving enough air, I have also come to realize that using air filters is a terrible idea and requires a lot of maintenance, so we just run filter-free, in fact, most of the dust that would accumulate on the filter won't be stuck on the miner, it will just enter and exit.

Using filters on your intake simply means the airflow will start to go down from minute one, if your intake fans move 10k m3/h without filters, with clean filters they won't do 10k, the filters themselves will reduce that amount, so maybe 8k m3/h with filters being brand new, the next day, some of those wholes will be blocked and now the 8k is 7k, so to maintain good flow you will have to clean the filters very often, in my case, i'd have to probably clean them every week at best.

Using air filters would be a good idea if you have at least double the amount of airflow, so even with filters half clothed, your miners still run clean with enough airflow, aside from that, using filters is just a pain in the ass, just run them without filters and then every couple months, shut down, do a bit of dusting and move on, dust isn't really a bad thing even if it was to reside in the miner as long as the temps are fine, humidity is miner's worst enemy.


That seems like a good plan, water-cooled pre-built containers like the 19XP container sounds like a better idea than immersion cooling.

Phill: remember to buy special power cables and ethernet cables, the normal ones will harden and crack and you will be changing them regularly.

Oh regarding cryptocooling.eu, i think scott works with those guys, i sent him a message on telegram, will let you know later.

I was never able to understand the economical logic behind using liquid cooling in mining, it's cool and all, but the cost is extremely high, if noise isn't an issue for you, why not just add more fans to the wall? or replace the ones you have with some strong fans like this or this

I would like to hear more about why can't you improve your air cooling.?

Ok, then I stand corrected, as I said, I don't have enough experience with BO+, I was expecting it would do the same thing with Vnish in regards to tuning down the hashboard to get them to a stable state, since this isn't the case, i'd think more manual intervention is required by the user, so perhaps always start below stock power, so 1200w for S9 and then clim your way up.

Ok it was not exactyl zero but close enough, a 0.19% drop which i would not complain about as long as it is not a possitive adjusment.

As explained in my previous post, current hashrate is hardly sustianble with the current bitcoin price, i know diff can do things out of the ordiniary but as it grows larger it won't be able to do much of that nonsence.

Based on that assumption and a few others, I believe now is a good time for stacking mining gears.

I am not very familiar with BO+ tuning but I believe it's similar to vnish, on BO+ you set a power limit on your miner which the firmware will try to achieve either by underclocking or overclocking certain boards/chips individually, similar to Vnish if you set a target so high which one of the boards can't stand the firmware would start to ignore your "target" and slowly adjust the setting to the downside until all chips become stable.

So setting a high profile from the get-go is not a good idea, the miner could take forever to actually get to a stable state, the best approach would be setting a profile/power limit similar to the stock, so something like 14TH on Vnish, or 1250w on BO+, then check the chip's status, if they are happy with the setting for 2-3 hours, you can try another push, maybe 1350w or 15th, if the miner takes too long to finish tunning it's probably telling you that your miner's capabilities are way far below what you are asking.

So in the above example if the tuning takes too long, fall back to 1300W or 14.5th, if the miner is happy with 1350w or 15th and your PSU is capable and you want to push it, go 1450w/16th, despite having to monitor the miner for a few hours, this is a lot safer and faster than going to 16th/1450w straight, because if your mine can only do 13th/1200w it will take so many hours for the runner to step down from 16th/1450w and you will think that the firmware isn't working when in fact you are pushing your miner way too hard.

Also, I don't recall if there is a default setting for ASICBOOST on BO+ but on Vnish it comes disabled, so make sure you enable it before tuning.
