Hashrates for Opteron and Xeon CPUs.
I'm looking for the benchmarked hashrates of both a 1.0GHz Opteron 2007 CPU, as well as a 1.2GHz Xeon 2007 CPU. I looked here but didn't see them mentioned.
Also, on that references page, I don't see anything mentioned for how the hashrates were computed. What mining app is being used as the benchmarker for all those stats? Thanks in advance!
Although those particular CPUs aren't listed, you can infer from the other CPUs in that table that the hashrate will be only a few Mhash per second. CPU mining isn't cost effective today. (Which is why the list of hash rates for CPUs is fairly out of date.) See also this question about whether CPU mining is worth it.
To answer your follow up from the question comments, it's not entirely clear how ASICs will change mining because the number of ASIC machines shipped has been so limited. If ASIC vendors could deliver in volume at the promised amounts of GHash, yes, they would probably be the only lucrative way to mine going forward. But all predictions regarding the future of mining have to be taken with a grain of salt: it's always hard to predict the future. The end of GPU mining has been predicted for a couple years now, but the rising exchange rate has been keeping it alive.
Best mining CPU 2020: the best processors for mining cryptocurrency.
The best CPUs for mining.
On the market for the best mining CPU 2020 has to offer? It's worth knowing that while over the past two years, cryto-currencies such as Bitcoin have peaked and dipped, mining for crypto-currencies has continued to intensify to the point where at present it's difficult to almost impossible for ordinary computer uses to mine them in any manner that is cost-effective.
The result is that mining rigs remain out of stock and not replenished, and serious miners are expected to have extended farms of hardware in order to keep going. However, there are cycles to economics, and while current conditions make it tough for mining, that doesn't mean to say it can't become accessible and profitable again in the future.
With that in mind, for hardcore miners and dedicated enthusiasts, it may yet be worth still investing in hardware for crypto-currency mining. Pair the best mining CPU with the best mining GPU and best mining motherboard, and choose the best crypto-currency for your needs, then you could soon have a mining powerhouse that can potentially start earning enough to pay off your hardware and energy use while still making some profit.
Here then are the best mining CPUs still on the market in 2020.

More on building Phi 7220 Mining Rigs...
Wow. What a community response. Unbelievable. Last week I posted on my latest toy, a rig that used eight Xeon Phi 7220 cards in a single 4u-server to achieve a total of roughly 24kH/s for cryptonote coins (in case you missed it, the original post is right below).
I had expected some interest in that merely because that was, to my knowledge, the new speed record for a single-node(!) mining rig.... but man, was I wrong: three thousand unique visitors in the first 48 hours, on a blog that didn't even exist until two days before. And tons and tons of interesting comments on questions, on both the blog and reddit.
Based on that feedback from the last three days, it's now become very clear that there's two follow-ups I'll have two write (else I'll drown in emails :-/). The first topic that came up again and again was "Vegas vs Phis" in terms of mining revenue, profitablity, etcpp .... and I promise, I'll write one - but I'll first wait for my 4×7250 node to arrive, so bear with me. The second big group of questions that came up again and again revolved around "how can I replicate that build" - i.e., how do the Phis work at all, where can I get them, and if I have them, how can I build a machine that'll take them. This latter question is what this post will be about.
Mining on Phi 7220 cards...
First off, it is kind of hard to get those 7220 cards - if you don't already have some, you'll probably have a hard time to get some. I got mine off ebay, but that seller - at least right now - doesn't list any any more, so manybe they're gone. Also, be sure to not confuse the x100 cards (3120, 5100, 7120, etc) with those newer x200 phis - the old ones will be about 5x slower, so think hard if that's worth it. Quite frankly, if you're interested in mining with Phis you'll be best off buying one of the 4×7250 self-bootable machines (I'll write more on that once mine arrives).
That said, if you already have 7220 cards - or miraculously found a good source for them - you'll have to find a way of actually hosting them, of getting them to run, and mining on them. In terms of mining software, lukMiner will run on them, and will run rather profitably. To get it to run, though, you'll need a copy of Intel's MPSS 4.x software stack to drive those 7220 cards - and since Intel took that product down that isn't all to easy to get any more. I still have an older copy from back-then-when, but don't have permission to share that, so you'll have to find somebody else to share that with you (If anybody that has a copy wants to share, please feel free to send a comment with a link!). Once you get both hardware and MPSS stack up, you copy luk-xmr-phi to the card, and run it; so that part is easy.
Now to the tricky question: How to actually build a rig with these cards. The problem here is that they seem to be working in only certain motherboards, and since they got pulled off the market there's no support. So all I can do is go and share the three successful builds I managed to create - without any warranty whatsoever that they'll work on your side.
Building a Rig - Option #1: the 24kH, 8-card, 4U server.
The build I used in my original post is a professional, off-the-shelf server from Exxact Corp. I used theirs because I know they had listed this product with Phis in the summer, so had pretty high confidence that would still work. For those interested in more details: It's a 4U server with two Xeon CPU slots, a C612 chipset (which seems to be important), 10 full-length PCI slots, and then (8+6) PCI power connectors, which works out perfectly. Since I didn't want to take any risks I bought a complete system from Exxact, with CPUs, memory, disks, 2x1600W power (fully redundant, so 4 PSUs actually), and everything else except the Phi cards, which I already had. In total - and with shipping - that set me back something like $6k, just as much as the cards themselves.
Of course, I could probably have built that thing from parts for much less (the two un-used redundant PSUs alone are worth several hundred bucks) ... but already having $6k in Phi cards on the line I didn't want to take any risks - and quite frankly, so far I've been extremely pleased with this purchase (and Exxact have been most helpful so far, too!). For anybody wanting to get this system, here a pic of both the rig, as well as the exact sticker of that machine (and I'm sure Exxact would be happy to help, too - just mention what it's for, they'll remember me :-/).
One final note: The careful reader will have seen that I mentioned ten PCI slots, yet my build uses only eight cards. Yes, I did fit 10 cards in there, but ran into some issues. First of all, I blew some circuits in my basement ... and worse, at home (where I built the rig) I only had 110V power, which wasn't all that good for the 2x1600W PSUs. And finally, when I did get it to boot the machine became unstable with 10 cards - maybe bec.ause of heat, or maybe because the drivers don't like that many cards, I don't know. Eight work, 10 I'm not sure. Might get back to trying, but for now I don't have any spare cards any more, anyway. Here a pic with 10 cards, but again, right now I only run eight. I'm not crazy. Not really, anyway.
Option #2: A Cheaper, but still professional rig.
Since $12k in a single rig is admittedly a somewhat scary thought I also played around with finding cheaper, smaller options. After looking primarily for the same board generation and C612 chipset I ended up with a SuperMicro SYS-5018GR-T server.
Initially this didn't produce enough air flow to cool the cards, but after a bit of "friendly persuasion" on behalf of the fans (ie, cutting the two control cables of the fans to make them go full blast - see pic) that worked out of the box, too.
Got the barebone for $1100 off ebay, plus a refurbished Xeon, and a single DIMM of memory .... all together probably around $1400 (plus cards) - not that much off what you'd pay for a typical desktop PC to put GPUs in - but in rackable form-factor, so you can actually farm it out to a co-hosting place.
Option #3: The totally Stone-Soup, Do-it-yourself Build.
OK, before I went ahead and bought all these servers and cards for now close on $20k I (obviously?) first did some simpler tests, buying only a single card, and testing that in something I already had. "Luckily" I had lots of un-used workstations lying around that I could test with ..... the reason I say "luckily" in quotes is that the reason I have those in the first place is that they started out as GPU mining rigs, but since "several" of those GPUs have died the mining death over the last few months I now have some unused workstations :-/. (yes, one of the reasons I switched to mining on Phis is that I simply had too many GPUs die on me - in particular a certain brand, but don't want to offend anybody, so will keep that part to myself).
Anyway - tested many different machines, and most didn't work. Either they didn't boot at all, or they booted but didn't show the cards, or had too old BIOSes (they need above 4GB decoding), etc. Finally found one of my machines that took that card, and for everybody that wants to replicate, here the specs:
Motherboard (likely the most important part): Asrock X99 Deluxe CPU: Some X core Xeon E5 bought off ebay - probably won't matterl A cheapo PCI 1x GPU to drive a monitor (won't need it for mining, though). Three Xeon Phi 7220 cards (started with one, but then put in two more) EVGA 850GQ (850W) PSU Phanteks Enthoo Pro M case (won't matter), and a single DIMM of 8GB of RAM. Lots of fans. CentOS 7.3 with MPSS 4 stack and lukMiner 0.8.6.
And la voila, here we are:
In terms of cooling, a regular workstation's case fans won't be enough. Not by a long shot they won't. At first, I added this semi-professional Lasko fan:
This obviously blows air to the inside rather than out of the case, but if you leave the case open that's OK (and if not, it's strong enough to make all other case fans go backwards, too, LOL).
Eventually, however, that setup looked a bit shaky even by my standards, so went ahead and scouted for some smaller fans to cool this. Typical case fans won't do, even if mounted right behind the cards. Eventually, however, I found some higher-powered fans on ebay (see, for example, here for a listing). The blue (printed) shroud doesn't actually fit the x200s (they have their power connectors organized differently from the x100s), but the case wouldn't have had enough space to host those shrouds, anyway, so simply took them off - the fans are strong enough to make enough air go through the cards even without a perfect fit. Oh, and of course: Duct tape is your friend In the following two pics, left one shows two such fans connected with two shashlik skewers and soem duct tape (I didn't say it was professional grade, did I?); the right one shows those fans mounted right behind the cards - one fan does one card, the other does two.
Again, I used the trick of messing with the fans' control cables, and simply have them go full blast (image on the left shows the fan connector cable cut open to allow a four-pin fan connector to connect to a two-pin 15V connector - the control wires aren't, but cut simply not connected, so they go full blast. Right image: That stuff connected to a 15V molex). With that, the machine is now up and running for three weeks, no issues whatsoever (well, had to fix a few issues with hung NiceHash connections in the miner, but the hardware works all right).
As mentioned above, I'm not sure that those builds can easily be recreated - for example, I have some other x99 boards that do not work, so I have no clue why this one does Ie, no warranties, and your mileage may vary). Anyway - for those that have some of those cards I hope this info will at least open a path to getting them up and running. As such:
Important Facts You Need to Know About Bitcoin mining.

FPGA Mining Cryptocurrencies in YOUR HOME?!|12:56

[Bitcoin]

One fundamental aspect of cryptocurrencies is mining. The fact that a computer can mine for virtual coins over a certain period is something to research appropriately before doing it.
Bitcoin mining refers to securing transaction networks and process each transaction successfully. The way computers do this is by solving algorithms that make them chain several blocks of the transaction. By doing this, Bitcoin miners get paid with other Bitcoins plus transaction fees.
Keep in mind that this is the foundation of Bitcoin mining, but many other things are going on in each transaction.
Here are 10 important facts that you need to know about Bitcoin mining.
Mining is Not for Everyone.
While mining Bitcoins seems like a profitable idea. It's way too expensive if you want to do it right. Bitcoin mining tends to be specialized, and professional miners use huge spaces filled with computers whose specific purpose is to mine 24/7. If you only have a laptop, it may be too expensive to mine up to the point of getting considerable profits. To invest in bitcoins, you can visit Bitcoin Era.
You Don't Have to Invest in Bitcoin to Mine Bitcoins.
While trading Bitcoin involves executing profitable trades to earn more money, you don't need to do that while mining. With mining, you're offering your computer to process transactions in a particular "Mining Pool," which means that you're going to get paid for offering that service, which is not the same as trading.
You Need Powerful Hardware to Mine Bitcoins.
As said before, mining Bitcoin properly can get too expensive if you want to take it seriously. If you want to mine properly and get considerable profit gains, you need a powerful GPU (Graphics Processing Unit) or an ASIC Miner (Application-Specific Integrated Circuit). ASIC Miners are computers that were designed specifically for mining Bitcoins.
Mining Consumes Too Much Energy.
The profitability of mining depends on your region's power costs. Mining a single Bitcoin can take up to 10 minutes in the most appropriate circumstances. The reason not everyone is mining is that it consumes way too much energy, so if you're going to try it out, make sure that you can cover the power consumption costs.
To Earn Money, You Need to Provide Proof of Work.
Mining is seen as a competitive activity. While the work essentially is solving a mathematical puzzle, your computer needs to be the first one to solve these puzzles in order to get the money.
While mining has been proven to yield great results for some people, the fastest way to get Bitcoins is by buying them since you get the money instantly.
Bitcoin mining is Not Legal in Every Country.
While many countries allow Bitcoin mining, you need to check your country's regulations to see if it's legal there, and what the tax implications of the activity are.
You Need to Set Up a Bitcoin Wallet.
If you want to mine Bitcoin, you need to set up a digital wallet where you're going to receive your earnings. Remember that each wallet has a unique private key; if you lose it, you lost your Bitcoins forever.
You Need to Join a Proper Mining Pool.
If you are a beginner, you need to choose a credible mining pool to work with. These usually give fewer profits, but you can still gain significant profits. To choose more accurately, you can look for graphs that show the biggest pools and choose one.
Mining Takes Time.
Even if you get the best equipment on the market, you're not going to get huge profits instantly. To get the most out of mining, you need to do proper research, invest money in good equipment, sort out any power consumption issues, and wait patiently.
There are many things to keep into account before mining. It certainly isn't for everyone, but if you want to try it out, make sure that you prepare adequately and take your time to start seeing profits.
Asics Bitcoin mining.
An application-specific integrated circuit (abbreviated as ASIC ) is an integrated circuit (IC) customized for a particular use, rather than intended for general-purpose use. Because they can only be used for one application, ASICs are expensive to design and produce. [1] [2]

ASIC vs CPU mining [ edit ]
An ASIC Bitcoin miner is designed exclusively for the purpose of mining bitcoin. Though significantly more expensive to purchase, they are far more powerful (higher hash rate) and electricity-efficient than CPUs and GPUs (graphics cards) - used for mining in the early days of bitcoin - and even FPGAs (field programmable gate arrays), which were, in 2011, the most efficient option. [3] According to Mike Murray, creator of The Geek Pub, a $2500 ASIC miner is as powerful as 400 GPUs, or 12,000 CPUs, which would cost $18 million. [4] For reference, as of February 2018, the Bitmain Antminer S9 possessed the highest available hashrate at.
14 TH/s, with an efficiency of.
0.1 Joule per GH/s, and cost $3200 on Amazon, not including the power supply. [5]
ASIC for Bitcoin mining hardware [ edit ]
Mining is now so competitive, and the difficulty rate so high, that attempting to do so without an ASIC is unprofitable. [3] [4] [6] Because ASIC mining hardware is so expensive, ASIC for Bitcoin mining is done by companies in thermally-regulated data-centers with access to low-cost electricity. Many of these companies lease part of their mining power as a service. [6] [7]
Cloud mining, or mining as a service (MaaS), is an alternative that allows individuals to mine bitcoins without handling their own hardware. [8] Because of the high cost it implies, many people may not want (nor be able) to invest in from-home ASIC mining. The hardware consumes high amounts of electricity, necessitates a powerful ventilation system, and is in itself expensive. As the writers at Coindesk put it, "cloud mining means using (generally) shared processing power run from remote data centres. One only needs a home computer for communications, optional local bitcoin wallets and so on" [8]
Several of the businesses listed below lease hosted processing power to customers.
Bitcoin ASIC mining companies [ edit ]
Listed below are some companies that produce bitcoin ASIC hardware and/or provide a cloud-based mining service.
KnC Miner [ edit ]
KnC Miner is a Sweden-based (Boden) start-up cofounded by Andreas Kennemar and Sam Cole in 2013, when they merged their IT consulting firm KennemarAndCole AB (KNC) with the chip designer house ORSOC in order to produce better Bitcoin mining hardware than was available at the time. [9] During the following years, they managed to raise $32m in venture funding from investors, including Accel and Creandum, and became one of the industry's fastest-growing mining firms [10]
On September 2nd 2014, KnCMiner launched the cloud service KnC Cloud, with facilities located in a former helicopter hangar 15 kilometers away from a Facebook datacenter in the Arctic. This location is beneficial for any mining center, since the naturally cold air saves the company cooling costs. [11]
In May 2016 customers successfully sued the company over delayed shipments and problems with the Titan, one of their hardware products. [12] Later that month, KnCMiner declared bankruptcy. [13] At the time, Sam Cole denied any connection between the lawsuit and the bankruptcy filing, claiming that the latter was a preemptive measure against the halving of the bitcoin block reward (which became 12.5 BTC that year). [13] In August of the same year, KnCMiner was bought by GoGreenLight, to continue operating the ASIC mining pool and data centers. [14]
CloudHashing [ edit ]
CloudHashing was founded by Emmanuel Abiodun in 2013. It operates from data centers in Kansas City with hardware by Butterfly Lab, Terrahash and KnCMiner. It was the first firm to offer MaaS. [15] In October of the same year, CloudHashing built a facility in Iceland, which generated more than $4 million worth of Bitcoins at the time [15] The company would lease 80% of its computing power to costumers. By December 2013, they had 4500 customers who were paying $999 a year to use machines that at the time cost $20,000 on the open market. [16]
In March 2014 Cloud Hashing had the combined calculating power of.
1,500 Th/s. The entire Bitcoin network's calculation power was 38,000 Th/s; thus, 4% of the entire network power was concentrated in the hands of this company.
After a successful 8-month-long period in 2014, during which the company mined over 35 thousand bitcoins at an equivalent value of over US$21 million based the price of bitcoin at the time, Cloudhashing merged with the advanced hardware manufacturer HighBitCoin to form PeerNova, releasing the PetaOne Blade, which featured a 28nm chip with a power efficiency of 0.35W per GH/s. [17]
In 2015 CloudHashing signed a supply deal with Australian bitcoin company digitalBTC, to run digitalBTC hardware in data centers in Iceland and Texas. This deal was dissolved later that year when digitalBTC pulled out of the agreement. CloudHashing then began increasing their customers' management fees and buying back contracts. [18]
How To Setup An ASIC Bitcoin Miner In 3 Easy Steps.
Setting up and using Bitcoin ASIC miners is currently one of the best ways to start mining for Bitcoin. Most of the veteran miner's already known by now, mining on a laptop these days isn't very profitable. Even some of the earlier versions of application-specific integrated circuits(ASIC) miners are no longer efficient in today's Bitcoin mining.
That's not the only important part you should know before jumping into mining Bitcoin with ASIC. You see there are a few other basic requirements you'll need in place to be successful at running even just one Bitcoin Miner let alone multiple machines.

Sounds easy right?
Don't worry, in this guide; I answer all the commonly asked questions I get from over the years of my experience in ASIC mining. Questions like "where to buy bitcoin miners," "how to set up a bitcoin miner," "what is the best bitcoin miner" and more, will all get answered in this article.
ASIC Mining Requirements Checklist.
One of the most popular mistakes new miners make is poor planning of where the ASIC miners will operate. That's why it's always a smart idea to have the location checked out first before making any financial decisions as to whether you should pursue mining Bitcoin.
ASIC Bitcoin miners consume decent amounts of electricity which is why it's important to know what the cost of the location per kWh ($) is before purchasing any miner hardware. Once you have the utility companies' prices, you can use a mining profitability calculator to estimate any Bitcoin ASIC miner's current profitability and operational cost.
This estimation alone should give you enough insight to decide whether all this is even worth pursuing given the locations kWh rate so make sure you learn how to use a mining profit calculator properly.
Each Bitcoin ASIC miner also requires its own dedicated 220v outlet. Having an inspection on your location's electrical system is another must-have to ensure you don't overload any circuits.
Another issue is with miners is heat. ASIC miners are notorious for heating small spaces in the wintertime which is excellent, but when summertime rolls around, you'll need a plan to circulate fresh air.
Other than a high-speed internet connection this all the core requirements your location needs to be deemed permissible for Bitcoin mining. However, I want to add in the fact that you will need an ethernet cable running from either your router or network switch for each Bitcoin Miner you plan on operating.

Best ASIC Bitcoin Miners To Buy.
The best place to buy Bitcoin ASIC miners is direct from the manufacturers most commonly headquartered in China which has been a leader in the industry of manufacturing Bitcoin Miners ever since ASIC minings existence.
Top 3 Bitcoin ASIC Miner Manufacturers 2019.
EBANG INNOCSILICON BITMAIN.
Buying direct ensure you don't overpay from other reseller sites like eBay. Most ASIC miner comes with a 6-month warranty which is another reason why it best to go direct.
Out of all the companies I just mentioned most of my experience has been with Bitmain as they have been the most popular for quite some time.
However, with this recent new batch of miners released they currently don't make the fastest Bitcoin miner.
Best ASIC Bitcoin Miner Of 2019.
The best ASIC Bitcoin Miner you can currently buy on the market today is the EBANG EBIT E11++ as it can mine Bitcoin at speeds of 44 Th/s while only drawing 1980 watts. It comes with a standard 6-month warranty and is currently priced at $2024 including the power supply.
In case you do decide to buy from one of the other manufacturers check to see if the power supply gets included. Companies like Bitmain require you to purchase their power supply and power supply cord separately.
ASIC Bitcoin Miner And Power Cords.
How To Set Up an ASIC Bitcoin Miner?
Now that you have all the required hardware and location prepped its time to set up your Bitcoin Miner to start earning Bitcoins. The setup requirements from miner to miner are very similar in some ways but it's still best to refer to the manufacturer's installation guide for specific instructions.
Step 1: Connect Power Supply.
The first thing you will want to do is make sure the power supply and all connections coming to and from the power supply and miner are tight and secure. Once the connections are secure, then proceed to plug the miner into the 220v outlet.
From here the miner should power on, but some miners may have a power switch which is why you will need the manufacturer's instructions.
Step 2: Connect Internet.
Now that you have your miner up and running its time to plug it into the internet directly with a CAT5 or CAT6 cable.
SIDENOTE: I've seen people use wifi adapters for these types of miners but for stability in connectivity reasons its not ideal.
Once the internet is connected, you can now begin to configure your miner's software, but first, we must locate the miner's IP address.
Step 3: Access Router.
To obtain a miner's IP address, you must first access your router configuration menu. If you are unsure of how to access your router's settings be sure to Google the make and model of the router. Each manufacturer should have instructions with routers IP address and default user name and password.
Step 4: Locate Miner IP Address.
Inside the routers settings menu will be an option to see all the devices connected to the network along with each device's IP address. You will want to copy and paste each IP address into your Google Search bar until you see a screen asking for your miner's user name and password.
Step 5: Login into Miner.
Each miner has a default user name and password located in the miner's installation instructions. Take Bitmain miner's, for instance, their default user name and password is "root."
Once you login to your miners operating system, you can now begin configuring your mining pool and wallet address. Be sure to leave the miner browser open while you get a wallet and mining pool address.
Step 6: Create a Wallet.
If you haven't set up a wallet by now, you will need to create one. One of the best software wallets for Bitcoin comes from a company called BRD which has been around for quite some time. However, if you're looking to hold some Bitcoin long term its recommend to invest in a hardware wallet.
Once your wallet is backed up and secure be sure to get a copy of your Bitcoin wallet address.
The next thing you will need to do is select a Bitcoin mining pool and sign up for an account.
Step 7: Sign Up at Mining Pool.
One of the first Bitcoin mining pools goes by the name of Slushpool and is a personal favorite of mine mostly due to its phone app monitoring features. Be sure to sign up with the link below and follow the help guide to setup worker names.
Slushpool Setup Guide Link.
Now you can select your pool server address but be sure to use one that is closest to your mining operations location.
Step 8: Configure Miner.
Copy-paste the pool address URL box along with the "your-username.your-worker-name" you setup with Slushpool into the user ID box.
The password box can be left empty when mining on Slushpool but other Bitcoin mining pools may require it so always refer to the mining pools getting started section for exact details.
Once you've copied everything into the miner configuration panel be sure to hit save and so the miner can now start pointing towards your pool and wallet address.
Congratulations, you have now crossed through the doorway of officially becoming a Bitcoin Miner.
Undoubtedly Bitcoin mining has made people a fortune over the years. However, that doesn't mean anyone who attempts mining Bitcoin will have guaranteed success with it. Most of the reports of profits made from Bitcoin mining are from wise investors who carefully planned out their mining operations with cheap electricity while using the most efficient mining hardware.
Speaking from my own experience, I too have witnessed Bitcoin mining being quite profitable partially due to Bitcoin,s bull run late 2017. Now after two years of running S9 Antminers I'm looking into upgrading my hardware as the S9's are no longer profitable on my .11 cent kW rate.
That's why I recommended calling the utility company first to get the kW rate so you can use it for better accuracy when entering a Bitcoin Miners wattage and hash rate into the mining profit calculator.
Keep in mind mining calculators can only estimate what a current ASIC miner's profits are as many unpredictable factors like mining difficulty and Bitcoins price make it change regularly. With that said they can still be a great tool to decide whether Bitcoin mining is right for your situation or not.

Crypto-Mining: How to Mine Monero on Raspberry Pi?|10:12

[Bitcoin]

There are, however, periods when Bitcoin's mining difficulty increases so much that mining isn't at all profitable unless your electricity is extremely cheap or free. When this happens, inexperienced miners can get very impatient and sell off hardware at a loss which is where most of the negativity about mining being dead come from.
In times like the instance mentioned above its crucial to keep a long term investment mindset with realizations that mining profits will have ups and downs like all investments do.
Especially crypto markets as they are unregulated which makes then extra vulnerable to market manipulation and is commonly used tactic to convince inexperienced investors to sell when they should buy and vice versa. It's essential you understand that this is the game your playing and understanding how its played will prevent you from making impulse and irrational decisions.
How long does it take to mine 1 Bitcoin? The time it takes to mine one Bitcoin can vary depending on Bitcoin's mining difficulty and the mining hardware hashrate used to mine them. However, you can calculate how long it currently takes a Bitcoin ASIC Miner to mine one Bitcoin by entering its total hashrate into a Bitcoin mining profit calculator.
The calculation should provide you with a daily estimated amount of Bitcoin a given ASIC miner can mine daily. From here you can take the expected daily amount and divide it by one to reveal how many days it takes your miner or to mine one Bitcoin.
How much does it cost to mine 1 Bitcoin? The cost to mine one Bitcoin can vary upon many factors such as mining difficulty, electric rates, and mining hardware efficiency. However, you can estimate this with a mining profit calculator using your Bitcoin miners hashrate, electric rate, and power consumption which reveal the daily amount of Bitcoin Mined and day-to-day operational costs which is your electricity costs.
The daily amount of Bitcoin mined can then be divided by 1 to reveal how many days it takes to mine one Bitcoin. From here take the number of days it takes to mine one Bitcoin and multiplies it by the current estimated daily operational costs to know how long it currently takes to mine one Bitcoin.
Can Bitcoin miners be used for anything else? Yes, there are other cryptocurrencies like Bitcoin Cash who use the same sha256 algorithm as Bitcoin in which you can use the same ASIC miner in mining them. However, you will need to use a different wallet and mining pool address in doing so.
Can I mine Bitcoins on my PC? Technically yes you can still mine for Bitcoin on a PC, but you would be far better off trying to mine altcoins like Ravencoin and Ethereum with them.
So by now, you should have a better understanding of what becoming a Bitcoin Miner is all about and how to know whether it's profitable for your situation or not. Just remember to plan out your operation first and get an idea of what your expenses are before buying any hardware. If you feel as though this guide helps you in some way or we left something important out, then please drop a comment below.

5 Best ASIC Miners For Bitcoin mining in 2018.
ASIC miners represent the latest generation of cryptocurrency mining equipment that has effectively replaced graphics processors. Canada-based GPU manufacturing giant Nvidia has recently pulled out of mining due to its low revenue, which is inextricably connected to the dominance of ASIC chips. At the same time, ASIC chip manufacturers are aiming to raise billions of dollars after going public.
Bitmain, the biggest crypto-oriented company in the world, still enjoys a near-monopoly on the cryptocurrency market. However, its major competitors are already breathing down its neck. Therefore, we will try to find out the best cryptocurrency miner out there.
How to choose a Bitcoin miner?
Before we get down to our top five picks, it is worth mentioning the main factors that will help you to determine the best Bitcoin ASIC miner for your personal needs:
Hash rate. Hash rate is measured in hashes per second. Obviously, the more powerful your miner is, the bigger block reward you get.
Efficiency. Hash rate is not the definitive factor when it comes to picking the best Bitcoin miner since it also has to make the best use of the amount of electricity you consume. Your mining profitability greatly depends on your electricity expenses, so you want to get the maximum amount of Bitcoin.
Price. At early stages of Bitcoin mining, it is all about offsetting your initial investment. You have to calculate the mining profitability and decide whether it's worth purchasing a flagship miner, or you can simply stick around with less expensive one that will give you more efficiency.
Biggest ASIC chip producers.
Bitmain. The Beijing-based company still controls the lion's share of the market (85 percent) despite the reports that this multi-billion dollar behemoth is gradually losing its monopoly status due to the cutthroat competition in this niche of the cryptocurrency industry. Bitmain managed to grow so quickly because of the enormous success of their Antminer line (which includes the legendary miner Antminer S9). It's also worth mentioning that Bitmain operates numerous mining pools (Antpool is the biggest one) that are responsible for more than 51 percent of the Bitcoin hashrate.
Halong Mining. The fact that Bitmain is hell-bent on getting rid of any other mining companies on the market it doesn't mean that there is no competition. Back in November 2017, another Chinese manufacturer introduced the world's most efficient miner Halong DragonMint 16T, continuing an intense ASIC mining hardware race.
Canaan Creative. Canaan Creative is the second biggest Bitcoin mining hardware manufacturer the world after Bitmain. Apart from a slew of its miners, the company has also recently introduced the first mining TV.
Now that we've covered all the basics, let us determine the best ASIC miner on the market.
Antminer S9, or Antminer S9 Hydro?
Antminer S9 has already became a legend among ASIC miners, but is this still good enough? You can currently buy 14 TH/s for less than $700. One of the drawbacks of this miner is that it is very sensitive to high temperature, so your primal task is to ensure that it gets proper cooling. The best choice is to have one specific room for mining (if you, of course, do not own a mining farm).
After the release of Antminer S9, Bitmain's previous hit product Antminer S7 has drastically dropped in price, so you might as well consider purchasing a couple of used S7 miners.

At the end of August, a brand-new miner appeared on Bitmain's official website named S9 Hydro. We are dealing with the good old Antminer S9, but they also added a hashing board that increases the total hashrate up to 18 THS. While there are no fundamental technological differences, S9 Hydro produces is not as noisy as other ASIC miners.
Will Antminer Z9 and Antminer Z9 Mini be able to battle ASIC resistance?
This is a relatively new miner by Bitmain (Bitmain announced the pre-order of this miner back on May 3). One of the specific features of this miner is that it supports the mining of Equihash-based coins, including ZCash (ZEC), Bitcoin Gold (BTG) and so on. In fact, this was first ASIC miner that is compatible with this specific algorithm, yet again serving a major blow to GPU mining.
With hashrate of 10K Sol/s and power consumption of 300 Watts will set you back about $850 while Antminer Z9 costs a whopping $3,319, offering 40.8k sol/s. However, with the way Bitcoin hashrate is rising, you never know whether this hardware becomes obsolete in a few months.
If you plan to purchase this specific miner, there are certain things that you have to consider the rising mining difficulty. Yes, ASIC Bitcoin miners are much more powerful than ordinary GPUs, but you may as well read that as significantly higher mining difficulty of Equihash-based cryptocurrencies. On top of that, many such coins could become ASIC-resistant similarly to Bitcoin Gold, which would virtually eliminate the miner's efficiency.

Halong Mining DragonMint T1- the first miner to offer 16 TH/s.
Halong Mining made an announcement about the release of Halong Mining DragonMint T1 in November 2017, marketing it as the most efficient machine out there. This ASIC miner really managed to pull off up to 16 TH/s, which is a visible improvement from 14 TH/s offered by Antminer S9s, our first entry on the list. DragonMint T1 has a tad higher efficiency compared to older Antminer S9s, but it didn't even come close to the previously declared numbers. With that being said, it's up to you to consider whether you want to pay $300 more for this miner.
One of the noticeable advantages of DragonMint T1 is its cooling solution which presented in the form of dual nine blade variable fans (they keep temperature just at 25 degrees).
It is worth mentioning that this miner was developed with Samsung (the company confirmed the cooperation in April). After landing a deal with the South Korean tech giant, Halong Mining poses as a viable competitor to Bitmain.

AvalonMiner 821 - creating competition for Bitmain.
AvalonMiner 821 was officially revealed by Canaan Creative last December to hold a candle to Bitmain's dominance after the success of its previous-generation AvalonMiner 741. This miner has a hashrate of 11TH/s. Unlike DragonMint T1, AvalonMiner 821 only has one cooler, but it still provides the owner with a substantial level of cooling. Furthermore, the miner is resistant to different temperatures.
The miner is absolutely compatible with huge mining pools like NiceHash.com, Slushpool.com.
AvalonMiner 821 trails Antminer S9s by 10 percent in terms of mining efficiency (this comes in addition to the lower hashrate). However, it is still a viable option for those who want to save some cash. It currently costs around $700. While you still have to buy a $200 PSU for this miner, a total of roughly $900 is still less than Antminer S9.
Whatsminer M10, Avalon A9 and more- new ASIC monsters are (almost) here.
This flagship product of a Shenzhen-based company Shenzhen is also worthy of your attention. Pangolin only recently announced this miner on Twitter, and it is only available for pre-order for $1,888 (first buyers will already get this miner by Sept. 20). Whatsminer M10, while offering 33TH/s of hashrate, uses about 81W per 1 TH/s, which makes it more efficient than its closest competitor GMO B3. Some engineers behind Whatsminer M10 come from Bitmain, so it explains its high level of productivity. However, there is some criticism surrounding Whatsminer M10- from negative reviews about M3's slow preorders to speculations about whether the miner matches its description on paper in real-life conditions.
Back in August, Canaan Creative made an announcement about working on a new brand-new Avalon A9 that is 7nm chip technology that is able to reach 30 TH while it's power consumption is only 1730W, thus ensuring a maximum level of efficiency. This technology definitely blows out of water even the newest Innosilicon Terminator 2. However, it is quite likely that every major ASIC manufacturer already has a new 7nm ASIC up its sleeve, so we have to wait and see whether Canaan will have a competitive advantage. Japanese tech giant GMO is also developing 7nm ASIC miners that are going to be launched as early as in 2018.

Mining bitcoin with Azure (and why it is a terrible idea)
Update:
Disclaimer:
This is extremely inefficient and will not earn any bitcoin. You will spend $1,000s of VM time for a near 0% chance of earning anything. A $30 USB device is.
100,000x faster for mining.
Again: YOU WILL NOT EARN ANY BITCOIN (less than 1c in a month)
TL;DR The commands to create a machine in Azure to CPU mine are at the bottom. But don't bother.
I have been playing with the blockchain lately, most notably the programmable blockchain Ethereum. I was interested in seeing how difficult it was to set up a machine to mine Bitcoin. What I discovered through my research was that it is possible, but pointless to do CPU mining in the cloud.
Why is mining on Azure bad?
While it is easy to set it up, CPU mining is extremely inefficient. Mining on CPUs was depreceated a long time ago when it was discovered that it was faster to do on GPUs. But now even GPUs have been deprecated in favor of power efficient ASIC machines.
Here are some hardware comparisions of ASIC devices from https://www.bitcoinmining.com/bitcoin-mining-hardware/
There are even cheap USB devices that you can plug in that give you GIGAhashes/second.
