That is indeed a factor, but I don't think it holds so much weight, we use the U.S dollar because it's the easiest medium of exchange that we understand, but in reality, bitcoin needs to go up in value against what the majority of the world uses a "currency", miners will have to pay for electricity and make some profit, so whichever medium of exchange they use to pay those bills must drop against the exchange value of Bitcoin.

The only advantage to mining in different mining pools is redundancy against pool failure, including problems with their server/node or any network related issue that would stop your miner from connecting to that pool, plus the chances of a pool closing down or refusing to pay you, but as far as luck goes, there is really nothing you can do to increase it.

If Slushpool's luck is giving you troubles, just mine to a PPS+/FPPS pool and you won't have to worry about anybody's luck, it comes with a higher fee of course.

@stompix , i skimmed through it real quick.


Bullshit, first of all most miners are on PPS, so a block is submitted or not isn't something they really care about, secondly and most importantly the majority of the nodes that matter is owned by Chinese pools, having your node in the U.S is nothing special, plus it is not like all these pools don't have servers in the U.S anyway.


I am not a north American miner, but what issues would one have with a Chinese pool that would urge him to migrate to an American mining pool?

The most important thing would be their fees, the rest is really just noise.

With that being said, I am happy to see non-Chinese mining pools joining the game, it is good for Bitcoin in general, after all, they can't be worse than the Antpool.

Thanks for finding the post, I started this topic to help the mining community locate repair services nearby, since sending gears back to China isn't working as it should, I believe this thread would be very helpful, I hope that we all band together to grow the list in that topic.

Shipping your mining gear back to China for repair isn't the best idea, shipping to and from China will cost a lot, or your miner could be "confiscated" by the manufacturer.

I thought there should be a list of good repair services that all miners can access locally based on their geographical location, this will ensure a cheaper shipping rate and a much faster repair process.

I will be updating the list regularly as information come by, if you have or know a repair service please share it here or send it to me via pm, I will try to do some basic research on all the services I list here, but you will deal with them at your own risk.

Inputs coming from trusted members of the mining community in Bitcointalk will be very helpful.

It's unlikely that someone will go to this extremes measure to scam, also since these providers are nearby, it would make sense that you could actually visit them in real life to confirm their integrity, while I wouldn't blindly trust them, I believe they are likely legit, but you MUST dyor.

Buying new S17s brand new from Bitmain comes with an average failure rate of 30% (please pay attention to the word average), so buying a second-hand gear from Alibaba comes with even greater risk, you should avoid all the 17 series altogether.

What newbies do is the following, they go to whattomine.com or any mining calculator for that matter and enter their hashrate + power rate and they get a monthly profit of X in fiat. For example, they enter 10 cents per kWh , 110th, and 3500w ( the specs of S19 pro). The result will be :

Total = $15.56
Net profit after paying the power bill =$10.50

Gear cost = 4000, so ROI = 4000/10.50 = 380 days or just over a year, what's funny is that even some of these calculators will tell you that you need 380 days to return your investment, but this couldn't be further from the truth.

These calculators assume static price and difficulty, and this is never the case, there is no way that both difficulty and price will remain the same, but you might say, well this is totally random since they can go either way, so 380 days could be 100 days and can be 500 days.

Well, not really, on the scale of probability and based on historical data from the genesis block up to now, the difficulty only goes up when the timeframes considered are a few months and above, on the other hand, price doesn't do that all the time. so it isn't a 50/50 chance here, it's worse, think of it as your odds against the casino.

With that being said, even if the stars were aligned perfectly and you did manage to get back your $4000 in 380 days and then you sell it for $2000 thus making a profit of $2000, that total $6000 you end up with might not worth the btc that you spend today, so while you may manage to ROI in USD terms, you lose big time in BTC, this assumes your gear will still be profitable and you won't be forced to shut it down sooner and sell it for pretty cheap.

There is a lot more to it than just this, this post is just the summary of how calculating mining profit isn't as simple as these websites show you, I can go on forever but the short version of my story is if you can't ROI in a few months, you have better chances making more profit buying BTC directly rather than going into the rabbit hole of mining.

As for solar, phill will be your guy, he runs most of his gears on solar power and he probably knows best.

ان كنت تريد ان نساعدك يجب عليك ان تهداء وتجاوب على الاسئلة, الاخ خالد سئلك سؤال محدد ( ماهي المحفظة التي تستخدمها)؟

بالنسبة لي 0.08496567 بتكوين التي تم تحويلها لي 1DppEPhySoSKfKP3RFoVJbaUXSbzLWQYr8 فهده خلاص راحت ولايمكن استرجاعها باي طريقة واي شخص يقول عكس هدا فهوا يااما نصاب او لا يفهم هدا المجال ابدا.

اما بالنسبة للباقي وهوا 0.10327963 فهوا على الاغلب لايزال يمكن الوصول اليه, فقط اعمل ريفريش للمحفظة ومن المفترض ان يظهر الرصيد

What you want is parallel mining, it's a long story, the short version of it is "no".

What you can do instead is download AwesomeMiner, it's free since you have only 1 miner, and then use the change pool command based on time intervals and so you can achieve

Son 1 worker : 12AM to 12PM
Son 2 worker : 12PM to 12AM

You can do 6 hours each or any other combination, but try to switch pools as less frequently as possible since it results in a loss of some mining rewards.

لم استعمل في حياتي منصة تفرض عليك رسوم على اي order لم يتم شرائه\بيعه, اي منصة تفعل هدا فهيا منصة نصب واحتيال!


ايضا لم ارى منصة تتيح التداول المجاني الا في حال كان هناك عرض مؤقت لجدب زبائن جدد او شي من هدا القبيل, مكسب المنصات من السحب قليل ولا يكفي ليكون مصدر دخل اي منصة محترمة, بالاضافة الى ان بعض العملات يمكن سحبها مجانا, والبعض الاخر تكون العمولة فيه شبه نفسها التي تدفعها المنصة لل miners يعني المصدر الرئيسي هوا عممولة ال maker and taker.

The 19 series uses a single large heatsink that covers all chips, Microbt M20s and M30s have two heatsinks each covering about half of the chips, also, IIRC the heatsinks are not glued/soldered to the chips, they are attached using some screws, of course, it's more than likely that they put the thermal paste in between.

This one large heatsink instead of one heatsink per chip design looks like it's going to be the future for all miners to come.

Different scenarios require different set-ups, at times more of less-efficient hashrate makes you more profit than more-efficient but less total hashrate, this is one good thing about custom firmware, using Vnish and a management tool like awoesomeminer you can automate this process, you enter certain variables such as price, difficulty, your power rate and etc, and then the software will handle the efficiency profile based on what's the most profitable at any given time.

If bitmain wants to stop the usage of custom firmware, they should implement this in their new Antrack, at least 3 to 5 power modes should be there, I don't think it's all that difficult for them to implement.

Indeed, I think they trapped him into sending his gear by quoting him an estimate of $30 to fix his S17+, what kind of a fix would bitmain put their staff on for $30  , anyway, people should look for alternative ways to fix their gears, check zeusbtc or ask other forum members about workshops that are specialized in mining, phill knows a few in the U.S he perhaps should make a dedicated topic in regards to that.

I usually ignore such questions since really almost all the information you need can be found around the forum, but you seem very serious and you put quite a lot of effort into asking your questions.

The sad truth is that it isn't a great idea to consider mining with the power rates you have, even your lowest tier rate is high, let alone the 3rd tier of 14 cents, while power rate isn't the only thing that separates a successful mining business from a losing one - it still is the most essenital factor, mining, in a nutshell, is competing with thousands of other miners around the globe.

It is pretty safe to assume that the average power cost for large mining farms is 4 cents, let's be "optimistic" and say its 5 cents per kWh, so your odds are terrible, and the chances that your miner will die before you hitting ROI are very high, now one mistake many miners do is focus on the fiat value of mining to determine a succesful business plan, there is no doubt that even with 14c kwh you might make $5000 out of the $4000 you invest in S19 pro, but this isn't how to look at it.

$4000 is 0.21BTC, are you going to make 0.21btc before your power bill surpasses your earnings or before the miner is dead? hard to tell, but unlikely.

Are you 100% guaranteed not to make a profit? of course not, miracles do happen, China might ban mining altogether or a hurricane hits 10-20 large farms in China making your S19pro 5 times more profitable, but you don't want to bet against the odds, at least not while making a business plan for your retirement.

They are lying to you, used S17+ go for above $1500, for $1127 you can only get S17-56th.


Point number 4 is really funny, they want to persuade you to sell them the miner at a much cheaper rate, nobody is going to pay 90%, they will be that "buyer" so (1127-30$)*0.9 = $987.3, also expect a 5-10% less with an excuse of bitcoin price is lower on the exchange they use.

Sorry that this is happening to you man, Bitmain is indeed a terrible company to deal with.

I believe the S19 pro will do a lot better than these numbers, the stock efficiency for S17 Pro is 39.5 W/T,  the stock values for the S19 pro is 29.5W/T, if Vnish can turn 39.5w to 26w then it should do a lot better in tuning 29.5w to below 20 range, anyway it won't be too long till we find out, I believe in a one to two months Vnish for S19pro should be ready.

Never really had one to wear 

13.4K is the ultimate bear scenario, eventually, we will HAVE to make a major correction down to the 20MA on the weekly, we have gone up 100% without any major correction, these corrections that happen every time will pretty much happen soon, and they are 25-35% easily, so it's up to the market as of when to take that dive, if it isn't 19.5k to 13.5k (30%) then it will be 22k to 15.5k, or 26k to 18k, the point here is that major corrections will have to happen and weak hands will panic and sell, so it's good to know that a drop of 25-35% is very likely and is very normal on the way up.

Now if you are a long-term investor, this shouldn't really mean much to you, these corrections happen so fast (2-3 weeks) and the market takes about the same duration to recover to where it tanked from, but if you are a trader waiting for good entries then placing buy orders near the 20MA on the weekly is almost always a perfect entry point.

With that being said, don't attempt to short bitcoin. .

$13400-$14000 would be my "guess".

Here is an interesting read https://www.theblockcrypto.com/post/84781/bulk-preorders-bitcoin-miners-spring-2021

This is the most important part:


My guess is that both TSMC and Samsung don't see mining as a sustainable long-term business, so it would make sense that these silicon providers will favor supplying other businesses, Bitmain vs Apple Nvidia or AMD is a clear lost-competition, and then we have Intel who has now turned to TSMC.

Here is another interesting article https://www.supercryptonews.com/bitmain-introduces-smaller-5nm-chip-with-new-mining-rig/

In short: Mining manufacturers can't get their hands on enough chips - Great news to all miners who already have mining gears bought at decent prices, the difficulty should stay within the 20T-25T range up until mid-2021 unless bitcoin price goes past 40-50k whereby the average joe can fire up his S7 and S5 then we MAY go to 30-35T, and keep in mind that difficulty of 25T with Bitcoin price at 18-20k is much better than how things were post halving, so the majority of miners should be mining happily for months to come.

Running a bitcoin "node" doesn't earn you anything, the mining rewards go to "mining nodes" and given the current nature of mining, at least 90% of the rewards go to people who don't even know how to run a node.

Now back to your question, exactly a year back I posted this thread called "For how long can we actually mine", I tried to evaluate the future of mining and what should bitcoin be worth in order to


And this came out:



This ignores the "unknown" block fees (So the "required" price is less than what shows in that table) because we don't know how will bitcoin be 10 or 20 years from now, are you going to increase block size to meet mass adoption on-chain or are we just going to keep the blockchain exclusive for huge final-settlements that are worth hundreds of thousands of dollars in order to fuel the mining incentives with a small block size?

I tend to agree that the second theory will be more likely, I also seem to prefer that approach (for reasons that are off-topic), but all in all, Bitcoin price is essential to its existence or at least to its securty and reliability.
