I would like to add a bit to the above answers, this is not just about "luck", it has a lot to do with numbers as well.

in other words, the difficulty is adjusted for every epoch based on the time it took to mine the previous 2016 blocks (actually 2015 blocks but doesn't really matter here).

Taking the current epoch as an example, the current difficulty is about 13.9T, and for miners to find a block every 10 mins for whatever left of the current epoch the hashrate must not change, which is never the case and that's why we need the difficulty adjustment in the first place.

Think of it this way:

 Diff / Hashrate = Time

* The difficulty formula is way more complicated, this is just to give you a clear simple explanation of how things work.


You want time to be 10, the hashrate is 1.39, you set diff to 13.9 to get

13.9 / 1.39 = 10

what happens when the hashrate changes? remember the diff is CONSTANT for every 2016 blocks, the hashrate is VARIABLE.

Now assuming the mining "luck" remains constant at 100%, and bitcoin price drops 30-40% in price, a lot of mining gears (let's assume 30%) will go offline, and the problem starts here

Diff (constant) = 13.9
Hashrate = 0.973 ( after a 30% drop)

 Diff / Hashrate = Time

13.9/0.973 = 14 mins

We don't usually see a 30% drop in difficulty and by looking at the previous epoch, we had about 15% drop in difficulty and it was massive, which means on average those 2016 blocks took 11.5 mins to mine, but that's just the average, it's very possible that at certain points in time the hashrate drops 10-30% and remains there for a while, and thus blocks will take longer to be found even with luck staying constant at 100% but with a little bit of bad luck - blocks will take even longer to be mined, I think it's easy to observe that during a bull market when people keep on adding gears online, you see blocks being found more often in less than 10 mins, and the opposite is true.

Without a block found, it does not matter how many transactions are there or who do they belong to, even if the guy who owns the largest mining farm wants to send some bitcoin and miners fail to find a block for 2 hours, he MUST wait for that block to be mined, you should also keep in mind that transactions with higher fees don't have any technical advantages over transactions with lower fees, they are just "economically" superior because miners are financially incentivized.

That sounds reasonable.


To be honest, even after 2 years of being around, the "rules" are still confusing to me.

If you read the Unofficial list of (official) Bitcointalk.org rules it has no rules regarding the trading of merit, however, there is another pinned topic FAQ: Everything you need to know about forum 'activity, account ranks and merit

It literally states:


Do I think that is a forum rule even though it's not in the rules' topic? YES. Am I 100% right about it? No clue.

Please tell me you dropped an extra number there by mistake, do you mean $1 per merit? if it's really anywhere near $10 per merit then why

 

I highly doubt that hornetsnest would pay $2710 to get that 271 merit, so if this is anything, he is probably farming accounts and not actually selling merit, or he is not aware of how much they go for. 


Since trading merit is against the forum rules, shouldn't the accused member/s be reported rather than tagged? I mean what stops them from trading merit even with an active flag and a dozen negative feedback?

Your settings seem fine judging by the fact that your daily hashrate shows, I assume you used a standard order

It says the following:


So seems like you have been outbid, and your orders got in the queue but prices never really went to or below your pay rate, I assume the guys who buy standard orders run some sort of bots to actually utilize the bidding environment if you want to outbid everyone else and make sure your order is valid throughout the period you need it to be, try placing a fixed order instead (comes at an extra cost obviously), or give MiningRigRentals a try since it seems to be everyone's favorite

Is that from the unpopular "Love Core" manufacturer? this is one reason why people should stop buying those types of gears, they have simply modified versions of either Inno, avalon or bitmian but you don't know which one is which, and they have no support, probably not even a web page for that matter, and the materials you may find online regarding such miners are little to nothing.

But judging by the common issues of other gears, usually, this problem is caused by high temperature, what happens is that the miner starts cool enough to hash at full speed, and then due to bad ventilation or anything else, they get way too hot, the miner tries to protect itself and drops voltage/frequency aka going to lower power mode which leads to less hash rate, cools down for a little but still even with that drop it's not cool enough so it shuts-down to prevent the dashboards from frying.

Another possible cause is also heat, but not the miner itself that heats up, the PSU, gets hot, fails to deliver enough power and problems start, other things like your router not liking the ongoing connections with the pool, it may drop outgoing/incoming packets, the pool doesn't like your miner for whatever reason, but ignore this for now and simply focus on troubleshooting for heat issues, flash a firmware, perform a hard reset, if that fails, try another pool, then another router, if all fails, copy-paste the kernel log here and let's try to find what's going on.

You were one of the best members around when you were posting about "technical" stuff that actually matter but then out of a sudden you became so active in this board in a way that puts you a few topics away from being the next cryptohunter, obviously with better writing skills.

As far as DEMANDING the edition of a post, i wouldn't set my hopes too high, we barely get people to change their feedback, let alone edit a post, the way i see it is that ibminer seems like a reasonable dude, i am pretty sure the effect of a single-line PM would be stronger than this topic.

I disagree, from mining as business's point of view it is actually good to have all those coins on the same algo, they keep a portion of the hashrate away from btc so mining btc gets a little bit more profitable,  adding up all sha256 coins we get what, 10E for an example? That is about 10% more profit mining btc, from another point of view you may be right, but profit wise, i disagree.


Bsv hashrate gets to as low as 1-2E for some days, after the halving, you can probably attack it by a single order on nicehash  , however, there is little to no financial incentives to attack bsv.

Good point, the average hashrate for both coins has been around 5-8E for the past month, let's use a worst-case scenario and say 8E, without prices change in different ratios between those two coins and BTC, it's safe to assume that 4E will move to BTC at the worst-case scenario, BSV halving is in 7 days, so that will not count towards the current epoch, BCH's halving is in 5 days, so some of it's hashpower might actually move to BTC this epoch.

Current BTC hashrate is about 107E, so 4E = 3.7%, not a big deal, goes out to show that only 3.7% of bitcoin hashrate's can attack the two shit coins with a 51% attack simultaneously.

1- Be the largest exchange by volume.
2- Buy the most famous "crypto market statistics" website (Coinmarketcap), more details here.
3-Attempt to start a mining pool.

Does not seem like CZ is trying to take control at all, pretty hard to smell any sort of centralization here. 

I am not sure if those hashpower sellers are legit or not, I doubt their integrity, I hate to say this but probably Nicehash is the place to go for hash rental, but you should still wait for other suggestions as I am not really into renting hashrate since I use my own gears.

Same here, I will send him a large cut, this pool saves us a lot of troubles, and knowing that my chances are slim to nothing, I don't mind paying a good donation to -ck, let alone minding a 1% increase in fees, if that is done on a non-solo pool I would most certainly complain, but solo? no problem whatsoever.  


Good luck, hope you hit 2 of them, on a side note and since this is the first page of this new topic I'd like to take the chance and shed some light on http://solochance.com/ which is a very handy website that estimates your chances of finding a block, simply enter your solo ckpool btc wallet or the hashrate.

بالرغم من ان حجم العينة صغير نسبيا ولكنه بكل تأكيد اكبر من اقتراحي المتمثل في 5 اشخاص  , لا اريد "استغلال" نتائج استبيانك لتأكيد وجهة نظري, وسأترك التحليل لك ولكل شخص يحاول ايجاد الاجابة عن كون ان مستقبل البتكوين يتمثل في كونها سلعة تخزينية ام عملة للاستعمال اليومي, وكما اوضحت حضرتك فالوقت كفيل بأن يثبث او ينفي اي توقعات نقوم بها الان, وانا اتمنى من كل قلبي ان تكون وجهة نظري خاطئة وان نرا اقبال على البتكوين من المستخدمين مثل ما نراه من المستثمرين.

عمل رائع, يستحق المزيد من نقاط الجدارة, سأحاول ان اتذكر ارسالها لهدا المنشور فور توفرها.

عملة الايثيريوم ليست سيئة للاستتمار وقد ترتفع اكثر من البتكوين, وهدا ما كنت اقصده بتوزيع الارباح , ايضا يجب ان تضح في الحسبان انه كما ان سعر الايثير يمكن يصعد لي 200$ او 500$ يمكن جدا ان يتجه الى 50$ او20$ لايوجد اي ضمان لعدم اتجاه الاسعار الى الاسفل وهدا ما اقصده بضرورة امتلاك بعض الكاش للشراء في حال انهار السعر, لا يمكنني ان اقدم نصائح دقيقة للاستتمار مثل المستويات السعرية التي يجب فيها البيع والشراء, ولكن نصيحتي ان تضع سيناريو الهبوط امامك تماما كما تضع سيناريو الصعود لتكون مستعد معنويا وماديا لكلتا الحالتين.

بالتوفيق.

شكرا على نصيحتك اخي Ryutaro

It's orange vs gray   if the "grey" people stop answering any questions that have Fahrenheit in them, I bet many will go unanswered   , that was a lame joke anyway, while I prefer to see Celsius so that I don't have to use google for that, but that won't stop me from helping here.


I hardly understand F let alone K.  


My initial guess is that his router is somehow dropping packets from itself to the pool, and that his miner's status page shows perfect reading but the pool doesn't, however, I don't want to jump to conclusions.

I second this, I ran a few miners for a period of 10 days IIRC, I used AwesomeMiner to manage the profit-switching, I was looking at the numbers thinking damn I wish I have used this thing from day 1, but by the time I got the payouts and compared them to the same hashrate that was directly mining BTC only, turns out not only that I wasted time setting that shit up and bothering my miners with all different difficulties every couple mins, but I also ended up making a little less than directly mining BTC. But obviously, in the grand scheme of things, nobody does that math and thus nobody will listen.

You mentioned all the details but missed out one crucial element which is WHERE does the hashrate fluctuate?  is it stable at 40-42th on the miner's status page but goes below on the mining pool side? or is it on the miner itself or both?

Please answer that question and provide the following:

1- Screenshots of the miner status page + the pool status
2- Copy paste the kernel log of the miner, use the code format


In general this usually an 'easy to fix' problem, I will take you to step by step to fix this "hopefully", meanwhile you can  this and this.


Seriously dude we as non-us-citizens should start demanding that people write temps in Celsius scale. When I read 80 degrees I thought it was a toaster at first.  

لاحظت ان هدا تاني موضوع لك تقوم فه بوضع عنوان او شرح مختصر ومن ثم وضع رابط الموضوع في موقعك, وهدا النوع من النشر غير مرحب به في هدا المنتدى , لا اعتقد انه ضد القوانين ولكنه غير مرحب به من قبل اغلب الاعضاء, انا لا امنعك من نشر موقعك هنى فهدا المنتدى ارض خصبة جدا للدعاية, ولكن الافضل ان يتم وضع الموضوع كامل هنا ومن ثم وضع مصدرهم في الاسفل ليكون المحتوى اللازم للنقاش موجود هنا في الاساس ومن ثم تكون حرية الدخول للموقع من عدمه خيار للمستخدمين.

ارجو ان تأخد ملاحظتي بصدر رحب, انا لست ضد وجودك هنا بالعكس تماما ان سعيد بتواجدك بيننا, انا ايضا لست مستاء لانك تضع روابط لموقعك, ولكن لاتعجبني الطريقة التي يتم بها ذلك, مع الاخد بالعلم اني لست مسؤول لا في هدا القسم ولا الاقسام الاخرى, انا مجرد عضو عادي او بالاحرى اقل من العادي.

I had like 40 or more posts deleted, those that had quoted posts did show the time and those that didn't - did not, so my guess is that your post did not contain any quotations.

As partially explained by hosseinimr93, phill deleted a few topics of his, I think that was his way of "protesting" against what he considered a bad joke.

I put a ton of effort into those posts, I do feel bad for seeing them go away, but I totally understand how phill feels about this "joke" especially that it's directly affecting him and his family, so I don't blame him.

 
I support the idea.

if the deleted post contains another post quoted inside it, the date of the quoted post would appear but if your post had no quotes - the date-time doesn't show, which is a bit annoying.

On a side note, I had a dozen of my posts deleted today, I guess for the same reason yours was (Mining related).
