Wat is Bitcoin mining.
Wat is Bitcoin mining?
De meeste mensen weten al dat Bitcoins worden gecreëerd door het proces van mijnbouw. Maar wat is Bitcoin-mijn en hoe werkt het?
Bitcoin mining is een proces van het bevestigen van Bitcoin-transacties en het opnemen ervan in een gedistribueerd grootboek. Het is de belangrijkste procedure van het hele Bitcoin-netwerk, omdat het het systeem beveiligt, ervoor zorgt dat iedereen correct handelt en nieuwe Bitcoins in de circulatie introduceert.
Natuurlijk zou er geen mijnbouw plaatsvinden zonder mijnwerkers. Mijnwerkers over de hele wereld houden het netwerk gedecentraliseerd door hun hardware en elektriciteit in te zetten om aan het systeem deel te nemen. Op hun beurt worden ze beloond met transactiekosten en vers geslagen Bitcoins. Deze beloningen stimuleren de mijnwerkers om het werk te doen en hun uitgaven te dekken.
Hoewel dit een grove vereenvoudiging is, vormt een dergelijk systeem van prikkels het Bitcoin-netwerk.
Hoe werkt Bitcoin mining?
Heel eenvoudig gezegd, het werkt als volgt:
Mijnwerkers zetten hun hardware op om Bitcoin-netwerktransacties te verifiëren. Geverifieerde transacties worden om de 10 minuten gebundeld in één blok van 1 MB. Alle netwerkcomputers moeten een ingewikkelde cryptografische puzzel oplossen om een ​​nieuw blok toe te voegen aan de Bitcoin-blockchain. De eerste computer die de puzzel oplost, voegt het blok toe en wordt beloond met Bitcoins.
Momenteel krijgt de mijnwerker, zodra een puzzel is opgelost en een nieuw blok aan de blockchain is toegevoegd, een bounty van 12,5 Bitcoins. De prijs neemt in de loop van de tijd af - hij halveert elke 210.000 blokken met de helft. De eerste mijnwerkers hadden 50 Bitcoins per blok verdiend, terwijl in 2020 het tarief zal dalen naar 6,25 Bitcoins. U kunt sites zoals Bitcoin Clock gebruiken om de bitcoin halveringevenementen bij te houden.
Houd er rekening mee dat er niet meer dan 21.000.000 BTC's zijn gemaakt. De kunstmatige limiet is noodzakelijk om het economische systeem van Bitcoin deflatoir te houden. Vanaf nu fungeren de nieuw geslagen Bitcoins als een stimulans voor de mijnwerkers om het netwerk te onderhouden, maar en het bedrag zal geleidelijk afnemen totdat alle 21 miljoen BTC zijn gedolven.
Mijnbouw kan zeer winstgevend zijn, vooral omdat Bitcoin blijft waarderen in waarde. Mijnwerkers verdienen ook gebruikerskosten die zijn betaald voor hun transacties. Soms ontvangen ze misschien helemaal geen beloning, omdat alleen de eerste mijnwerker die de puzzel oplost, de prijs verzamelt. Een dergelijk systeem moedigt mijnwerkers aan om gezamenlijke mijnenplatforms (boerderijen) te vormen, waar alle leden dezelfde blokbeloning delen, waardoor hun winstgevendheid toeneemt.
In 2025 wordt 95% van alle Bitcoins gedolven, terwijl de rest tegen 2140 op de markt komt. Na die tijd krijgen de mijnwerkers alleen de transactiekosten als beloning, maar dat moet een beloning zijn die groot genoeg is om het netwerk te behouden gaan.
Kan jij Bitcoin mijnen?
Bitcoin is een volledig open-sourceproject; dus is iedereen vrij om zich aan te sluiten bij het Bitcoin-netwerk en deel te nemen aan mijnbouw. Dat garandeert echter geen winst, omdat je speciale mijnuitrusting moet kopen en elektriciteitsrekeningen moet betalen die duur kunnen zijn. Om geld te verdienen met Bitcoin-mijnbouw, moet u extreem krachtige computers aanschaffen (bekend als ASIC's), investeren in koelapparatuur en opslag. Vanwege de hechte competitie tussen de mijnwerkers, is het onmogelijk om te mijnen met een eenvoudige pc of GPU in thuisomstandigheden.
U kunt erachter komen hoeveel u kunt winnen door een Bitcoin mining-calculator te gebruiken; veel zijn online beschikbaar.
Je kunt ook een bedrijf met platformen betalen om Bitcoin voor jou te ontginnen. U tekent een contract waarmee u ze gedurende ongeveer twee jaar mijnbouw betaalt en ontvangt periodieke uitbetalingen van munten, zoals per overeenkomst. Voordat u echter een dergelijke deal sluit, moet u berekenen of deze winstgevend genoeg voor u is.
Als je denkt dat mijnen te risicovol voor je is, kun je ook een bijdrage leveren door toevoegingen aan de bestaande Bitcoin-code te schrijven, je eigen applicaties te maken of eenvoudigweg het project te promoten. Bitcoin is een community-driven project, wat betekent dat iedereen welkom is om op alle mogelijke manieren te leren en bij te dragen aan het netwerk.

'Bitcoin mining' voor beginners.
Altijd al willen weten hoe 'Bitcoin mining' precies werkt? Vandaag leg ik aan jou uit hoe het 'minen' van digitale valuta in zijn gang gaat. Je gele helm en pikhouweel mag je vandaag echter thuislaten, die hebben we niet nodig.
Ongeveer zes jaar geleden, of zeven, of vijf, dat kan ook. Ik dwaal af. Goed, een aantal jaar geleden werd mij voor het eerst verteld over digitale valuta en dan met name Bitcoins. Een vriend vertelde mij enthousiast dat je deze op een speciale manier kon verdienen, je kon Bitcoins 'minen'. Een soort goud zoeken met je computer, ik had gelijk last van goudkoorts. Natuurlijk zette ik mijn felgele helm op, trok ik mijn overal aan en zette ik mijn pikhouweel op mijn schouder. "Laat dat fortuin maar komen!" dacht ik bij mezelf.
Dat fortuin kwam er echter nooit. Nadat mijn computer een hele week op volle toeren heeft staan draaien gaf ik het op. Naast de 20 cent die ik verdiend had, had ik nu ook een boze vader. Iets over hoe ik het in mijn hoofd haalde om zoveel stroom te gebruiken. Of ik wel wist hoeveel geld dat kostte. Dat soort dingen.
Maar waar was mijn computer die week eigenlijk mee bezig geweest? Hoe werkt het 'minen' van Bitcoins? Was mijn computer afgedaald naar de donkere spelonken van het internet om hier op een Minecraft-achtige wijze tegen digitale steentjes aan te hakken? Nee, het 'minen' van Bitcoins werkt net even anders.
Vacature vrij voor Blockchain-controleur.
Op de Blockchain van de Bitcoin zijn altijd vacatures vrij voor Blockchain-controleur. Elke Blockchain heeft controleurs nodig om te kijken of alles wel eerlijk verloopt. Op deze manier houden zij het Blockchain netwerk draaiende. Je krijgt er ook nog voor betaald, uitgekeerd in Bitcoins.
Hé dat is toevallig! Met werkzaamheden als Blockchain-controleur kan je Bitcoins verdienen. Ook als 'miner' zijn er Bitcoins te verdienen. Begint het kwartje te vallen? Zouden beide functies soms precies hetzelfde inhouden?
Ja, dat doen ze zeker. De functie van 'Blockchain miner' houdt precies hetzelfde in als Blockchain-controleur. 'Bitcoin miner' staat alleen iets leuker op je cv, denk ik. Klinkt wel fancy, toch?
Maar hoe gaat het 'minen' van Bitcoins nou eigenlijk echt in zijn werk?
De taakomschrijving van een Blockchain of Bitcoin 'miner'
Laten we stellen dat onze 'Blockchain miner' Egbert van Oldenhoven heet. Vraag me niet waarom. Egbert controleert in het Blockchain netwerk van de Bitcoin de gemaakte transacties. Allereerst gaat hij op zoek naar verschillende transacties die gemaakt moeten worden, deze bundelt hij. Op het moment dat Egbert genoeg transacties heeft gebundeld voegt hij deze als bundel toe aan de keten van alle gemaakte transacties, de Blockchain. Is Egbert de eerste die een blok gemaakt heeft? Dan wint hij en is de transactie verwerkt.
Oké, maar hoe kom je aan al deze transacties?
Goede vraag, hoe kan Egbert transacties controleren als hij de transacties niet eens kan vinden? Waar kan hij de transacties vinden?
Op het moment dat iemand in het Bitcoin netwerk geld wilt overschrijven van rekening A naar rekening B roept hij over het hele netwerk:
"Hallo! Ik ben Pieter en ik wil graag 2 Bitcoins van mijn rekening overmaken naar de rekening van Klaas. Help mij alsjeblieft!" .
Elke 'miner' op het Bitcoin netwerk die deze boodschap hoort roept deze door naar andere 'miners'. Op deze manier krijgt ook Egbert weet van de roep om een transactie. Egbert gaat snel aan de slag met het verwerken van de transactie.
En hoe worden deze transacties dan verwerkt?
Egbert verzamelt meerdere transacties en bundelt deze samen in een blok van transacties. In het Engels spreken we van een 'block'. Op het moment dat hij een 'block' met transacties heeft verzameld zegt Egbert tegen het Blockchain netwerk:
"Hoi Blockchain netwerk, ik heb hier een bundel met transacties die naar mijn mening goedgekeurd kunnen worden. Zouden ze toegevoegd kunnen worden?".
Ah, een 'block', wat is dat dan?
Het bundelen van alle transacties is voor Egbert het meeste werk. Je kan het bundelen van transacties, of het creëren van een 'block', zien als een soort hele moeilijke puzzel. Alle transacties moeten op een bepaalde manier in elkaar passen. Egbert zal de oplossing van de puzzel moeten zien te raden. Op het moment dat Egbert de puzzel correct raadt heeft Egbert een 'block' gemaakt. Dit 'block' wordt dan toegevoegd aan keten van blokken.

Hoe worden er met 'minen' Bitcoins verdiend?
Voor elk 'block' dat een Egbert toe weet te voegen aan de Blockchain van de Bitcoin krijgt hij van het Blockchain netwerk een bedrag aan Bitcoins. Op het moment van schrijven is de beloning voor het 'minen' van een 'block' in het Bitcoin netwerk 12,5 Bitcoin. Word echter niet meteen te enthousiast. Het maken van een 'block' kost heel veel werk en niet te vergeten, heel veel stroom.

Wat is Bitcoin minen? Een simpele uitleg over de strijd om nieuwe BTC.
Bitcoin minen is inmiddels een begrip in de wereld van bitcoin. Bedrijven investeren én verdienen miljoenen in deze industrie. Maar wat betekent bitcoin minen eigenlijk? Een uitleg over de constante strijd voor het volgende block.
Even vooraf: het minen van bitcoin heeft niets te maken met het delven van grondstoffen. Er komen geen donkere mijnen of pikhouweels bij kijken. Toch gaat de vergelijking met het delven van bijvoorbeeld goud hier wel op.
Er moet namelijk wel gewerkt worden voor de buit. Het minen van bitcoin is een miljardenindustrie die bestaat uit partijen die grotendeels speciale hardware constant laten werken om een nieuw block te vinden. In dit block zit een beloning voor de gelukkige winnaar.
De kans op een block is op het moment van schrijven zo'n 19.38 biljoen. Om je kans te vergroten wil je zoveel mogelijk pogingen doen om zo je kans op het 'lot uit de loterij' vergroten. En daar is computerkracht voor nodig. Computers hebben energie nodig om dit werk te verzetten.

Bijdragen aan het netwerk.
In principe zijn de grootste miners momenteel vooral bezig met geld verdienen. Je investeert (in de regel) geen miljoenen in een onderneming omdat je bitcoin zo'n leuk idee vindt. Er is een constante strijd gaande tussen miners om efficiënter en daardoor beter te minen.
Er is voor deze partijen dus een financiële motivatie om bij te dragen aan het netwerk. En daarmee komen we bij een belangrijk punt: doordat het aantrekkelijk is om bitcoin te minen, wordt het netwerk veiliger.
Wanneer er meer computerkracht bezig is met de strijd om nieuwe bitcoin wordt bijvoorbeeld de kans op een '51%-aanval' kleiner. Bij een 51% aanval probeert een partij (of meerdere partijen) het merendeel van het netwerk in handen te krijgen.
Het netwerk van miners is inmiddels zo groot dat het nagenoeg onmogelijk is om op deze manier roet in het eten te gooien bij bitcoin.
Een mooie bijkomstigheid: wanneer er meer computerkracht meedoet op het netwerk, wordt het vinden van een block ook moelijker.
Bitcoin minen is, als je het plat slaat, niets meer dan het omzetten van energie in (een kans op) bitcoin. Dat is interessant voor partijen die goedkope energie hebben of goede hardware hebben. En als het kan het liefst allebei.
Transacties verwerken.
Naast een beloning in de vorm van nieuwe bitcoin krijgen miners bij het vinden van een block ook de mogelijkheid om bitcoin transacties te verwerken.
Normaal gesproken pakken miners de beste betaalde transacties. Een miner stopt transacties uit de wachtrij , ook wel de mempool genoemd, in hun gevonden block. Daarmee verwerkt een miner een aantal transacties, de transactiekosten zijn voor de miner.
De verwerkte transacties worden vereeuwigd in de blockchain. Letterlijk vertaald is dat een ketting van blokken (blocks). In deze blocks vind je de gehele transactiegeschiedenis van het netwerk.
De regels van het netwerk worden overigens door onafhankelijke nodes constant in de gaten gehouden en bekeken. Klopt het niet of probeer je vals te spelen? Dan zal de rest van het netwerk jouw versie van de boekhouding niet accepteren.
Een miner, of andere speler op het netwerk, is er dus bij gebaat zich te houden aan de regels. Je wordt door tienduizenden partijen in de gaten gehouden. Miners die een nep block vinden of transacties proberen toe te voegen die niet kunnen zullen worden geweerd.
Miners moeten er dus voor zorgen dat zij bijvoorbeeld geen dubbele transacties verwerken. Daarom is het aan de hardware om goed te kijken of de transacties die zij verwerken wel kloppen.
Ook de partij die een transactie bevestigt en verwerkt moet dus goed opletten.
Door deze structuur is het dus geen bedrijf als PayPal, Mastercard of Visa die de transacties verwerkt: maar hardware overal ter wereld energie stoppen in het vinden van een block.
Eisen.
Voordat miners bitcoin kunnen verdienen door het verifiëren van transacties moeten zij aan twee belangrijke zaken voldoen: zij moeten voor zo'n.
1 megabyte (MB) aan data verwerken aan transacties. Dat kan er slechts eentje zijn, maar in de praktijk zijn dat er vaak duizenden in één block.
Daarnaast moet er dus worden gewerkt. Het bewijzen van het werk doet een miner door een code te raden, die code noemen we een hash. Miners gebruiken hardware die per seconde duizenden hashes kunnen raden. Zij zijn in feiten constant bezig met het zoeken (of gokken) van het juiste lot uit de loterij.
Oh, en als extraatje moet je voordat je een beloning krijgt ook de eerste zijn die de oplossing vindt. Na het vinden van een block begint de wedstrijd opnieuw. De oude hash is niets meer waard en alle opties liggen weer open.
Bitcoin minen.
Het minen van bitcoin is inmiddels een miljardenindustrie met spelers overal ter wereld. Het minen van bitcoin begon op oude laptops op stoffige zolderkamers. Door het gebrek aan concurrentie kon je op veel hardware meedingen om nieuwe bitcoin.
Na een fase waarin grafische kaarten voor games werden ingezet om bitcoin te minen is er sinds 2013 een ware revolutie gaande. Rond deze tijd kwamen de eerste computers op de markt die speciaal zijn gemaakt om zoveel mogelijk hashes in een seconde er uit te kunnen persen.
Tegenwoordig hebben de grootste miners grote datacentra die speciaal zijn ingericht om mee te doen in de strijd om nieuwe bitcoin.
Als je mee wil doen in deze brute industrie is het aan te raden om je ook aan te sluiten bij Bitcoin mining pools. Deze groepen werken in feiten samen. Wanneer iemand een block vindt die bij jouw groep hoort, dan verdeelt de groep naar ratio de opbrengsten. Wie meer werk levert verdient meer geld.
Bitcoin miners zijn belangrijke factoren in de wereld van bitcoin. Zonder miners is er geen werkend en veilig netwerk. Er is voor deze partijen een financiële motivatie om bij te dragen aan het netwerk. En bij die jacht op nieuw kapitaal maken zij ook het netwerk veiliger.
Deze stimulans wordt in goede banen geleid door een belangrijk protocol: Proof of Work: Het consensus mechanisme van Bitcoin (BTC).

How to Mine DASH with AMD GPU.
Our renewed interest in both mining and altcoins, especially DASH. We decided it was time to try and mine again. X11 altcoins haven't been "ASIC'd" yet, meaning there isn't specialized hardware for X11 algorithm cryptocurrency. This has made X11 altcoins easier to mine with consumer hardware . I own an AMD Radeon 280X in my own desktop, so I figured I'd give it a run. It was both tougher, and easier to setup than I thought. I've mined Bitcoin many times before in the past and present, but with ASIC hardware thousands of times more powerful than consumer hardware, Bitcoin mining requires a ridiculous initial investment . Bitfury's new chips do promise to change that though.
Why is DASH Easier to Mine at Home?
DASH mining won't be profitable at this level for much longer, so get started now!
Understanding that DASH utilizes the X11 algorithm is important to understand before mining. DASH developers created this algorithm specifically to make it difficult for companies to manufacture hardware that solves it . X11 consists of 11 different cryptographic algorithms, so it's more suited for GPU mining rather than CPU, although it is possible, but GPUs are more powerful at this. This makes mining more available to the people and decentralized as Bitcoin mining has become increasingly centralized. With that out of the way, let's get into this. X11 AISC are on there way, so if you have a gaming rig, start mining now. It wouldn't be profitable for long!
Getting started with DASH Mining.
What's needed?
DASH Core Wallet.
Windows Computer.
AMD GPU of the following:
Cape Verde: 7730/7750/7770.
Pitcairn: 7850/7870/R9 270/R9 270X.
Tahiti: 7870XT/7950/7970/R9 280/R9 280X.
Hawaii: R9 290/R9 290X/R9 295X2.
Sgminer.
Time and electricity.
Step 1: Get a DASH Wallet.
If you don't have a DASH wallet, please download the core program here. Personally I don't trust payouts to third party wallets, so I always download the core program, regardless of cryptocurrency. Open the program and it will begin downloading the blockchain, which will take a while, so it's important to do this first . Be sure to backup this wallet while using it to ensure your Dash doesn't get lost.
Step 2: Download SGMINER.
Sgminer can be downloaded here, at GitHub.Be sure to extract everything and keep it in an easily accessible folder. Other websites may include viruses with sgminer, so be careful when downloading. This is the mining program for AMD GPUs. It also comes with binaries for use with other devices, but this tutorial only covers AMD GPU mining.
Step 3: Configure Sgminer.
In the folder with sgminer.exe, create a text file named sgminer. Open the file and go to save as, select "all files" and save it as "sgminer.conf". This will act as the configuration file when sgminer is running. It will tell the program how fast the GPU runs, what pool/masternode to use for mining verification, and what wallet the mined DASH will be sent to.
First, copy and paste this in the text file:
"pools" : [ "url" : "stratum+tcp://162.243.104.174:7903", "user" : "XheyzUntHSgmg1Qoo3NdNeoqLTiAAt1zhA", "pass" : "", "algorithm": "darkcoin-mod" > ], "xintensity" : "64", "worksize": "64" >
Step 4: Start Mining DASH.
Now that the miner is configured to send DASH mined on this computer to your DASH wallet, let's fire it up. Go to your installation folder and run sgminer.exe. If all is right, the screen should look something like this:

I for one think it is absurd the way BTC has gone up of late. There must be good(-ish) reasons for it doing so, namely speculation by folks with too much disposable money to know what to do with for the high risk portion of their portfolio, and, maybe, criminals of one kind or another. (And when I say criminal, I mean anyone who commits any kind of action prohibited by the letter of law -- so lots of folks, since downloading stuff became easier, cheaper, faster and arguably harmless).
But still, wtf. No matter how useful bitcoin can be for money laundering or buying drugs, nothing as far as I can see justifies this ridiculous rise in value.
Let's say just 1% of the world's population sees the value in bitcoin as an alternative currency. Let's say that they each want the ability to store the equivalent of $1000 USD. That means:
.01*7E9*1000 = the amount of value the currency needs to be able to store = $70 billion.
Let's do a reality check. If we look at the world's reserve currency, the USD, what's the size of the monetary supply? I think we'd want to look at M2, which is at around $10 trillion. So, Bitcoin would be sitting at less than 1% of that. That doesn't sound too insane.
So, to hold $70 billion in value across 11 million coins, each coin must be $6,363 in value. Look to the future of bitcoin and its 21 million coin limit and we're down to $3,333.
That means that if you believe in a future where Bitcoin has any importance at all, it's gotta go up quite a bit yet.

How to Generate Bitcoins from Your Home Computer.
IMPORTANT UPDATE: This process does not work anymore. For an updated guide about Bitcoin mining read this post.
If you've heard about Bitcoin you probably also heard about Bitcoin mining. Bitcoin mining is the process of turning computing power into actual Bitcoins. It allows you to generate Bitcoins without the need to actually buy them.
Now a lot of people say that mining can't be done on a home computer and that you need very expensive equipment in order to start mining, but that's not entirely true.
Any computer can be used to mine Bitcoins, even the oldest and weakest laptop you have lying around at home. Actually not so long ago a successful experiment was made where a 55 year old IBM computer was used to mine Bitcoins.
But of course, whenever you start looking for guides on how to mine Bitcoins it's always very technical with terms like "hash-rate" and "SHA-256" and all sorts of other weird terms. So you find yourself struggling with these terms until you finally just give up the notion of mining Bitcoins all together and just move on.
the good news is that you can mine bitcoins at home, using any computer you have laying around in a simple and easy process.
The only thing you're going to need is a computer that is connected to the internet. Personally I suggest using a computer that isn't being used for anything else since the mining process is very demanding and will slow your computer down substantially.
First, go to Bitminter.com. On the nav bar select "Join" and create an account. Make sure to remember your username as we will be using it in the following steps.
Then go to "tools", "Bitminter client" and choose "latest update". This will download a file to your computer that will allow it to start mining Bitcoins.
Once the file has finished downloading just run it and follow the simple installation instructions. It doesn't matter if you're on a Mac, Windows or Linux computer, the program will run smoothly on any operating system, you just need to make sure you have Java installed. If you don't the program will ask you to install it once you run it.
Once the program is up click "Engine start", enter your username and Voilà! you are now mining Bitcoins from your home computer.
A few important things before we conclude. Make sure to keep your computer cooled down using a fan or a dedicated cooling device. If you don't your computer may overheat after a while and damage itself.
You'll also notice that if you mine on your home computer you're probably mining very slowly and won't get enough Bitcoins to even cover the electricity cost of running the computer. For example on my home computer I made 13 satoshis after one full day of mining.
If you want to calculate how many Bitcoins you can mine on your own computer just use a mining calculator and enter your processing speed. You can see your processing speed at the bottom right side of the Bitminter program.
If you want to increase your mining rate you can always attach dedicated bitcoin miners to your home computer. Today's Bitcoin miners are known as ASIC miners , ASIC stands for Application Specific Integrated Circuit and it's bASICally an ultra powerful computer designed just for mining Bitcoins. You can find many used miners on eBay or just buy a new one online.
To sum things up you can still mine bitcoins at home using any old computer. You probably won't be very efficient but if you want to get a taste of what it means to be a Bitcoin miner, you can do so in just 2 minutes using the technique we just discussed.
How to Make One Bitcoin From Home.
Bitcoin supply is limited - it is 21 million. No less, no more. So it is a pretty rare asset, especially considering that there are over 7 billion people on Earth. That's why having even one Bitcoin is awesome. If the cryptocurrency grows in value, you would be able to buy an apartment in London, a premium Porsche car and a couple of Rolex watches. It seems like a promising goal! So let's talk about how to earn one Bitcoin.
In the crypto industry, everything changes extremely fast: exchange rates, mining difficulty, new algorithms. In order to simplify our calculations, we presume that cryptocurrency exchange rates don't change and mining of Bitcoin and Ethereum will never stop. Ethereum creator Vitalik Buterin wants to switch from PoW to PoS and when it happens it will be impossible to mine Ethereum on GPUs and transactions will be validated by node staking. Developers have been willing to change the algorithm for several years but still haven't done it.
Here are three ways to earn one Bitcoin. The first method is the easiest, the other two involve mining and calculations.
Method One. Regular Job.
You can have a regular job, get paid and save money. You can use this money to buy small bits of Bitcoin using Localbitcoins, a Telegram bot or other platforms. For example, today 1 BTC costs around $5,250.
So if you want to make 1 BTC in a year, you have to save around $440 every month. It's quite a lot.
Accordingly, if you want to make 1 BTC in two years, you have to save around $220 every month. Remember that you must have a wallet to store your BTC. Be smart and buy a hardware wallet - it's one of the safest ways to store coins.
Method Two. Bitcoin mining.
This is the most "hardcore" method: instead of buying Bitcoin, you can mine it yourself. You don't necessarily need to know what mining is, but you'd better have an understanding of it. Consider mining as the process of making money out of air and electricity, even though in reality it is a bit more complicated.
In order to mine Bitcoin you need ASIC. It is a device that was specifically designed to mine Bitcoin and can't do anything else. To date, the best available ASIC is Antminer S17+. According to Bitmain website, it costs $1,567 without Power Supply Unit (PSU) + $86 for PSU. Recently Bitmain has announced S19 and S19 Pro, but they are unavailable for sale yet.
The miner gives out 67 Th/s on SHA-256 and consumes almost 2.7 kW. Let's use WhatToMine calculator. Our favorite 2CryptoCalc supports only algorithms for GPU mining, but soon it will be available for ASICs as well.
According to the calculator, Antminer S17+ brings 0.3866 BTC a year. Don't forget that Bitcoin network hash rate is constantly growing. Last year it increased three times - it means that competition is growing, while it's getting harder to make coins using the same hardware. If we presume that next year it will be growing at the same pace, real annual profit from ASIC will hardly exceed 0.25 BTC.
Let's move on: if one device can mine 0.25 BTC, then in order to make 1 BTC in a year you need four such devices, which corresponds to as much as $6,268 without Power Supply Units. Plus we don't consider the placement of ASICs (they are too noisy to be kept at home - editor's note), their power consumption, etc.
If you want to make 1 BTC in a year, then ASIC mining is not for you. It is cheaper and easier to simply buy 1 BTC.
But let's say you are ready to spend two years - remember that mining difficulty grows three times annually. We get 0.25 BTC in a first year and 0.085 BTC in the second year. In this case, we need to buy three Antminer S17+ devices in order to make 1 BTC in two years. $1,567 x 3 = $4,701, which is the bigger part of our initial capital of $5,250 allocated for buying 1 BTC. Would you be able to find where to put these four guys, set up an Internet connection and pay electricity bills for two years using the remaining sum of $549? Unlikely.
Each device consumes 2.7 kW, which means 47,304 kWh in two years. And we have three devices, so it is 141,912 kWh in total. Considering the electricity cost is $0.04 per kWh, you will spend $5,676 on electricity, so $549 mentioned above won't save you. The budget already amounts to $10,377.
Do you still remember that you can buy 1 BTC for $5,250 without any fuss? So, in this case, Bitcoin mining is not a good option either.
Maybe you would disagree because you think you can sell your hardware later. Sure, you can do that. But after one or two years of usage, the price in the secondary market will be insignificant. It would be a miracle if you could return 10% of the initial price. We already discussed it when choosing which hardware is better in terms of mining performance - ASIC or GPU.
Method Three. Ethereum Mining.
Ethereum cryptocurrency ranks second by capitalization in the world. In order to mine Ethereum you need to use GPUs instead of ASICs. As a rule, miners build a mining rig of eight graphics cards.
"What am I supposed to do with Ethereum?" you might ask. "I want Bitcoin!" Fair enough. But who stops you from mining Ethereum and then exchanging it for Bitcoin on the crypto exchange? You can even mine directly to the crypto exchange. For example, 2Miners ETH mining pool supports this payout method.
We don't recommend keeping money on exchanges, so you can regularly transfer your Bitcoin on a crypto wallet.
In terms of economy building a new rig right now is not cost-effective, so let's see how much ready-made solutions cost. A quick search shows that you can buy them at a price of around $700.
For Ethereum AMD is a better option. But if you are a professional miner, you can use Nvidia - it will allow you to mine more profitable coins. For example, now Aeternity brings much more profit than others.
Let's say, we bought a mining rig with AMD graphics cards for $700, hash rate is 180 Mh/s. Let's enter these data in 2CryptoCalc.
Note that you can buy AMD graphics cards with at least 8 GB of RAM. GPUs with 4 GB will soon be unable to mine Ether.
The rig will bring 0.014 ETH per day, which means 5.11 ETH per year. Ethereum mining difficulty increased only by 23% in a year. Presuming that it will continue growing likewise, we can make a slight correction. The result is 4.5 ETH per year or 0.11 BTC.
Seems like another failure? In order to earn 1 BTC in a year, you need to buy as many as 9 rigs worth $700 each, which makes $6,300 in total. Not so fast. Unlike ASICs, GPUs can be easily sold. There are more gamers than miners - it's a fact.
In our experience, you can sell one-year-old graphics cards and return 70% of the initial price. Maybe you will have to disassemble the rig and sell graphics cards separately, but it's totally worth it. If you decide to sell the whole rig at once, you can expect to return 60% of the initial cost.

[Bitcoin]

Our rig consumes around 0.8 kW. If we buy 9 rigs, we will get 7.2 kW. It's a lot, but not too much. Today many people have such power at home. Besides, rigs don't make much noise, especially if you use regular PSUs for computers. And even if you use server PSUs, you can still keep mining rigs at home.
Let's calculate the annual electricity costs. 63,072 kWh at the price of $0.04 per kWh will cost $2,500. This is how much you will have to pay for electricity.
$6,300 are spent on mining rigs $2,500 are spent on electricity $4,410 come back after selling rigs.
So we have spent $4,390 to make 1 Bitcoin. We have saved $860 by mining cryptocurrency instead of simply buying Bitcoin.
In case you can't keep rigs at home, you should also consider that you will have to rent a location and include the rental costs in calculations. If your electricity cost is less than $0.04 per kWh, you can actually save money.
Conclusion: How To Make One Bitcoin?
The laziest option is to save money and buy 1 Bitcoin. Ironically, making 1 Bitcoin is less expensive if you mine cryptocurrency on GPUs. In this article we calculated values for Ethereum mining. A beginning miner may find it weird, but that's what many miners on the 2Miners pool do.
By the way, the scaling tactic is especially popular. First, you buy one or two rigs and once you begin to make money and understand the industry better, you can buy more graphics cards and start scaling. This way you can minimize risks and achieve your goal faster.
If you want to learn more about mining, make sure to check out other posts in our blog and if you have any questions you are welcome to ask them in the 2Miners pool chat. See you there!
The 2Miners pool co-founder, businessman, miner. In 2017 started mining cryptocurrencies and built many rigs on his own. As a result, he gained lots of practical knowledge and became interested in sharing it with others. In his articles on 2Miners, he shares useful tips that he tried and tested himself. For example, Darek gives advice on how to buy hardware components for the bASIC mining rig and how to connect them to each other correctly. He also explained lots of complicated terms in simple words, such as shares, mining luck, block types, and cryptocurrency wallets. After the pool was launched, he published a series of articles 'Crypto Mythbusters' where he explained how to protect the network against 51% attack, talked about cryptocurrency mining difficulty and difficulties of launching your own node.

How to Mine Bitcoin at Home With CPU Mining.
This post was most recently updated on December 5th, 2018.
Do you want to Mine Bitcoins?
People think that it is not possible to mine Bitcoin at home with your personal computer and that you need the best Bitcoin mining hardware and to join a Bitcoin mining pool for the mining to be profitable . Since the price goes up the mining difficulty goes up even more.
That is not true!
I have been mining Bitcoins with this browser CryptoTab for a while and it seems to be generating Bitcoins, and since my computer is on, all the time, why not earning some Bitcoins while it is on.
Also, they have a referral program with 10 Levels. I have so far more than 800 referrals and my earnings are growing every day while other level referrals join.
Click Here to start mining bitcoin online from your PC.
Cryptotab Account Dashboard:
This is my mining browser dashboard. Actually, mining is off and there are 0.000369 BTC in my account since I made a withdrawal 2 or 3 days ago.
Referrals page:
I have more than 800 referrals but only 100 are active in the last 24 hours. Meanwhile, time passes even if you don promote anymore your referral link, other level referrals join and earnings grow exponentially.
Proof of payment:
This is a proof of payment page. I withdraw every 2-3 days approximately $2-$3 and payment is send in less than 24 hours.
In reality, Cryptotab is mining Monero which is possible to be mined at home using CPU power and then converted into bitcoin.
I found an interesting project called Nimiq, which can be minted by CPU. My personal opinion is that it is very undervalued at the moment and has an x 100 potential for growth.
BASICally what I am doing now, is mining with Cryototab and making around $0.65 a day in Bitcoin and buying approximately 430 NIM a day. At today rate 1 Nim=$ 0.0015.
Some points about NIM:
Nimiq is very easy to use. Vey fast transactions Very low fees No premined coins Great community NIM has been added to Ledger Nano S And the most important thing, in my opinion, very bad marketing, almost nothing, which is great and means if you get in now, you will be from the early adopters. Another thing about NIM is that did not hit yet any big exchange, so when this happens the price will spike very fast.
If you are interested in mining browsers also check the Nimiq Mining Guide.
I would like to hear from you guys what do you think about this in the comments below.
How to Mine Bitcoin In Your Mom's Basement.
Here's what you should know before jumping into cryptocurrency mining.
My cousin has always been one for cockamamie get-rich-quick schemes. This time, he's finally on to something: Bitcoin mining.
Over the holidays, after a family dinner at his parents' house on Long Island, my cousin invited me downstairs to show me his latest big idea. In the basement, I came face-to-face with whirring machines, Ethernet cables, power adapters, and exhaust tubes snaking around the room. All of this, he explained, comprised one Bitcoin node and two Litecoin nodes. My cousin's new DIY cryptocurrency mining operation was booming.
Bitcoin and other cryptocurrencies such as Ether, Litecoin, and Ripple have exploded into the mainstream over the past year. Skyrocketing prices have stoked an ongoing craze to get in on the action. Most casual traders are happy with simply buying and selling coins using exchanges and storing their cryptocurrency using wallet apps. But those looking to dig deeper (sorry) and willing to lay out some capital can invest in the hardware, software, and shared ECOSystem to actually mine cryptocurrencies like Bitcoin.
I've written a lot about blockchain, so I was fully aware of the compute power needed to mine cryptocurrency (more on that below). That night, though, was my first time seeing an active Bitcoin mining rig up close.
"Did you learn how to code?" I asked him.
Nope, he replied; he bought the preconfigured mining hardware online and has been learning the rest as he goes along. Cryptocurrency mining is not simple, nor is it cheap to get up and running. But if you're looking for a source of steady supplementary income or want an expensive new hobby, you can do it.

Mining Litecoin|3:43

[Bitcoin]

My cousin walked me through how he set up his mining rigs and operations, the ins and outs of the mining world, and the benefits and challenges (both monetary and technical) to making a profit.
1. What Exactly Is Bitcoin mining?
Mining cryptocurrency is probably not what you think it is. Bear with me, because the process takes some explaining.
First, to clarify, mining Bitcoin doesn't mean extracting some kind of monetary value. In actuality, miners are key to how a blockchain works. There is a great deal of nuance to this, but to put it simply, blockchains are decentralized global networks of computers or "nodes." You can do all sorts of things on a blockchain, but at its core, the network executes, validates, and records transactions on a shared, immutable ledger. Miners are the ones bundling transactions into "blocks." A new block is created on the Bitcoin blockchain approximately every 10 minutes. At the same time, new bitcoins (from the cryptocurrency's fixed supply of 21 million) are uncovered and released into circulation.
For each 10-minute period, a miner or "worker" node is chosen to validate transactions. This happens through Proof of Work, a compute-intensive process akin to solving a constantly changing math problem. Miners generate a unique code string of "hash" that essentially serves as a lottery ticket to solve for Proof of Work and to be chosen at random for block validation.
2. Block Rewards.
What incentive do miners have? As a reward for solving Proof of Work and becoming the block validator, the miner receives what's called a block reward. The current block reward is 12.5 bitcoins, but the reward value is halved every 210,000 blocks, or roughly every four years. The reward started at 50 bitcoins in 2009, fell to 25 bitcoins in late 2012, and was halved down to 12.5 in 2016. The next halving down to 6.25 is projected to occur in 2020.
At current prices, 12.5 bitcoins is still a heck of a lot of money. That said, mining is an extremely competitive process. Most miners, including my cousin, join a mining pool to combine computing resources and split the rewards. There are other costs and complications to consider, but now that we've covered the bASICs, let's take a look at my cousin's at-home mining setup.
3. DIY Cryptocurrency Mining.
This is my cousin's at-home mining setup. The two rigs on the left are mining Litecoin, and the rig on the right is mining Bitcoin. We're going to break down all the parts at work here, what they cost, and how you can get them.
Your first thought might be, "Why aren't these on a rack instead of the folding table my aunt uses for barbecues in the summer?"
Answer: Hey, it doesn't have to look pretty as long as it works. But that's one of my cousin's next priorities. Aside from making the operation look a little more professional, though, housing the mining rigs in a computer rack reduces the surface area from which heat can escape, which will be important when we talk about energy efficiency further down.
4. Bitcoin Rig.
5. A New Antminer S9.
Bitmain (a mining-hardware company that makes a number of popular rigs) also recently released the Antminer S9. This more powerful and more energy-efficient miner is designed for the increasingly more intensive computing needs of the Bitcoin blockchain. The downside is it costs around quadruple the price of the S7, though it also offers almost quadruple the energy efficiency rate.
The S9 packs far more power, mining at a hash rate of 14 terahashes (TH) as opposed to the S7's 4.73 TH. Whether you buy a few cheaper S7s or spring for a new S9 is up to you, but regardless, you'll be laying out a significant amount of capital to get into the mining game. My cousin got recently got himself an S9 (not shown in the photos above) and traded in his S7 back to Bitmain to offset the cost of the new rig.
6. Litecoin Rigs.
7. Full-Service and Cloud-Based Mining.
Bitmain is one of several full-service companies providing hardware to buy or lease mining software and services, such as pooling and cloud-based mining. For enterprising miners like my cousin who don't know how to code and don't have the expertise to build their own rigs from scratch, companies like Bitmain and hosted mining providers, including ASICSPACE and Genesis Mining, are the easiest way to get started.
Bitmain also owns a few other sites and companies, including Antpool for combined mining of Bitcoin, Ether, and Litecoin; BTC.com for price tracking and wallet apps; and Hashnest for cloud-hosted mining, where you simply lease or purchase miners in a data center or "mining farm" and pay off a miner over time through a "payout accelerated cloud mining contract" with tiered pricing plans for faster hash rates. It's a way to start mining cryptocurrency without laying out money for the hardware or paying recurring electric costs, allowing you to manage your miners through mobile or web apps. But cloud-hosted mining gives you less control and locks you into subscription costs as opposed to owning hardware outright, so it's all about preference.
8. Cooling Systems.
9. Ethernet Bridges and Network Adapters.
10. Power Supply.
11. Heat Venting.
12. Software Interface.
13. Mining Pools.
Mining pools are the key to making your investments viable. Joining a pool combines your compute power with that of other workers within a cryptocurrency's blockchain network to increase your chances of solving Proof of Work and reaping block rewards. Numerous mining pools exist for various coins. Bitmain has Antpool, but my cousin uses popular mining pool Slushpool for Bitcoin mining and Litecoinpool for his Litecoin nodes.
Each pool has different rules governing how rewards and transaction fees are distributed. Slushpool takes a 2 percent fee calculated from block reward and transaction fees and pays out based on various formula and score-based rewards policies. Litecoinpool, on the other hand, pays per share using a process called merged mining . Payout nuances aside, pools are a must because of sheer firepower. For context, think about a single Antminer S9 worker with a hashing rate of 14 TH. Slushpool currently has more than 68,000 active workers, combining their compute power for an average hash rate of more than 1.7 exahashes (EH).
A quick lesson to drive that home: Most computer users are familiar with the denominations mega (million), giga (billion), and tera (trillion). Beyond that is peta (quadrillion) and exa (quintillion). So that's 14 terahashes individually versus 1.7 exahashes in a pool. Reaping mining rewards is about sheer compute power and random luck; the more lottery tickets you buy, the better your chances will be. Hence, pools.
14. Challenges and Drawbacks.
Getting up and running with mining rigs has some challenges. We've talked about the price of the hardware, but my cousin explained some of the other issues he's had.
First, electricity costs are high. My cousin makes approximately $17 per day per L3+ rig versus $2.92 in daily electricity costs. Profit for the S7 Bitcoin worker depends on the compute difficulty of solving Proof of Work for a given block. He estimates that his electricity costs for a year of 24/7 mining will be around $2,000. He projects, on the other hand, that his revenue should hit around $18,000. That sounds like a lot before you factor in all the capital laid out for mining rigs, adapters, power sources, and so on, but if you keep mining long enough, paying off initial investments and increasing profit, it can turn into a steady revenue stream. Even if you get to a point where electricity costs and other expenses outweigh rewards, and you decide it's not worthwhile to mine anymore, you can hold onto your coins and make money in the long term.
To restate, the biggest barrier to entry is that mining is expensive. You can calculate your potential profits per day, week, month, or year using this calculator that takes into account your hashing power, power consumption, and electricity costs broken down by cryptocurrency.
Mining is also difficult, and plenty of things can go wrong. Rigs run 24 hours a day, every day, and any time spent offline means potential lost block rewards in an endeavor where profitability is already difficult to achieve. Take it from my cousin, who called my aunt in the middle of the night to help him fix one of his rigs. Half asleep, she tried to follow his instructions over the phone before hanging up and going back to bed. He had to come home the next morning to fix it.
15. Want to Heat Your House This Winter?
My cousin is always in search that next big money-making idea, which in this case means diving deeper and deeper into the cryptocurrency world. He told me his next big venture is a datacenter upstate, where he and a business partner plan to set up their own mining farm and start a cloud-hosted mining business. In fact, for this story, he insisted I refer to him as Sam Alboher, COO of New York Mining Operations (NYMO). He said he's handling daily operations for the business and that the goal is to have 100 or so machines up and running, making money through sell contracts (selling computing power from the farm to miners) for return on investment. Whether that will succeed, time will tell. For now, he's just another enterprising miner with a pickaxe, off to join this generation's digital gold rush.
Another pet project of Sam's is hooking up the exhaust tubes from his rigs (currently venting heat outside) to an induction fan to heat his parents' house this winter and offset electricity costs. Hey, if miners in Siberia can do it, maybe he can too.

Mining bitcoins by hand.
Ken Shirriff decided to mine bitcoins by hand, to illustrate what cryptocurrency math looks like in practice. As he notes, the calculations aren't terribly complicated -- but going by hand, it's pretty slooow:
Doing one round of SHA-256 by hand took me 16 minutes, 45 seconds. At this rate, hashing a full Bitcoin block (128 rounds) would take 1.49 days, for a hash rate of 0.67 hashes per day (although I would probably get faster with practice). In comparison, current Bitcoin mining hardware does several terahashes per second, about a quintillion times faster than my manual hashing. Needless to say, manual Bitcoin mining is not at all practical.
Ah, but what about the energy consumption? Would bitcoins mined by hordes of humans be more energy-efficient than the current power-use trajectory, which is trending rapidly towards Dyson-sphere-construction?
Nope. Humans aren't a very efficient way to do math en masse:
There's not much physical exertion, so assuming a resting metabolic rate of 1500kcal/day, manual hashing works out to almost 10 megajoules/hash. A typical energy consumption for mining hardware is 1000 megahashes/joule. So I'm less energy efficient by a factor of 10^16, or 10 quadrillion. The next question is the energy cost. A cheap source of food energy is donuts at $0.23 for 200 kcalories. Electricity here is $0.15/kilowatt-hour, which is cheaper by a factor of 6.7 - closer than I expected. Thus my energy cost per hash is about 67 quadrillion times that of mining hardware. It's clear I'm not going to make my fortune off manual mining, and I haven't even included the cost of all the paper and pencils I'll need.

Mining bitcoin by hand 1 min read.
I came across a very interesting post on Reddit the other day. My wife is really good at maths (having studied physics) and we have long argued about bitcoin, and what it's doing. But despite evenings looking for a simple way of showing how the bitcoin algorithm is calculated. But no more, with this blog post discussing the maths behind bitcoin by San Francisco based Ken Shirriff.
His calculated total for this experiment? 0.67 hashes per day.

Desktop Crypto Mining App Honeyminer Comes to MacOS.
John Biggs.
HoneyMiner, a desktop-based crypto mining application, has released a new version for MacOS users.
HoneyMiner, which launched in July 2018, accesses your CPU or GPU and uses it to mine various cryptos. A central server points the connected machines at a certain target like ethereum, ethereum classic, zcash, monero and other GPU-friendly currencies.
"We have over 1,400 different kinds of GPUs on our network and it's all about routing the right computation to its most optimal use case and whichever chain is optimal," said co-founder and CEO Noah Jessop.
The HoneyMiner app takes 2.5% of the proceeds for multi-GPU machines and 8% from single GPU users.
Screenshot courtesy of HoneyMiner.
The Mac OS app works just like the Windows version. Upon launching the app you get 1,000 free satoshis and I was able to mine the equivalent of six cents in ten minutes.
This writer's estimated 24-hour earnings on a 2016 MacBook Pro running a 2.9 GHz Intel Core i5 was 113 satoshis or - and don't get jealous - $0.012 USD. The expectation is that users with more powerful computers will speed up the mining pool considerably.
HoneyMiner joins apps like DesktopMining.net and open source solutions like MultiMiner in its aim to make it easy to mine on almost any machine. They expanded to MacOS thanks to public demand.
"We launched on Windows first because there are so many powerful GPUs sitting under people's desks around the world and lots of folks getting started with mining do so on windows," said Jessop. "We've now got people in 167 countries on Honeyminer and have had literally hundreds of requests for Mac OS from our community."
Porting the app to MacOS was quite a chore, said Jessop.
"Mac was really tricky to run super smoothly on both CPU and GPU when available team spent months - maybe even too long - making it work," he said. "If we let everyone mine with the efficiency of the pros, software know-how becomes less of a barrier."
Bitcoin mining revenue hits yearly high, after return to pre-halving levels.
Bitcoin mining revenue has topped $20 million per day, its highest level this year.
Key on-chain metrics such as Bitcoin mining revenues have returned to pre-halving levels according to recent research.
Data from analytics provider, Glassnode, suggests that revenue from Bitcoin mining is now back at the same levels it was as when block rewards were double what they are now.
When the halving took place in mid-May, BTC prices were around $9,000. On November 18 they had doubled to $18,000 which suggests a correlation as miners need to sell enough of the asset to cover their expenses while remaining in profit. Higher prices mean greater profits.
Blockchain.com, which tracks the total value of coinbase block rewards and transaction fees paid to miners confirms the findings.
The daily revenue figure, which includes block rewards and transaction fees, for Nov. 18 was $21.2 million, its highest for a year. The previous peak was on May 6 when it reached $20.6 million. Following the halving event, which dropped block rewards from 12.5 BTC to 6.25 BTC, revenue plummeted to just over $7 million per day.
Mining revenue saw an earlier slump on March 18 this year following the pandemic-induced crypto market crash which wiped 45% off the price of Bitcoin in less than a week. When mining revenue falls steeply, over-leveraged miners can begin capitulating due to unfavorable market conditions.
The opposite appears to be happening at the moment as prices approach their all-time high.
Another factor indicating that the network is healthy and miners are happy is the hash rate, which is now just 10% away from its highest ever level.
Following the end of the rainy season in China, where the majority of Bitcoin mining takes place, rigs were powered down in preparation for relocation as cheap hydroelectric power dried up. This resulted in a seasonal hash rate slump of 37%, to below 98 Exahashes per second.
Since then, hash rate -- which many believe is correlated to prices -- has recovered to 143.4 EH/s which is not far off its mid-October peak of 157.6 EH/s according to Bitinfocharts.com.
The current mining revenue figures and hash rate recovery bodes well for the continuation of the bull market which may just take Bitcoin prices to a new all-time high before the end of the year.

What Hashrate to Expect From an Up to Date CPU.
Using the CPU or the central processing unit of your computer to mine crypto currency is pretty much considered outdated nowadays with the only exception being mining new altcoins that are CPU only. If you are interested to find out what hashrate you can expect to get from a powerful multi-core CPU at the moment with come of the more popular crypto algorithms in order to compare to your AMD Radeon 280X GPU or Nvidia GeForce GTX 750 Ti for example, you might want to look at the results we got below. They are achieved using the cpuminer-multi fork on an Intel Core i7 5820K processor (6 core with HT or 12 logical cores) running at default operating frequency (non-overclocked).
Algorithm - Hashrate: Scrypt - 129 KHS Scrypt:N - 26.2 KHS Sha256d - 10.7 MHS Blake - 18024 KHS Cryptonight - 192.7 HS Fresh - 487.2 KHS Lyra2 - 744.8 KHS Neoscrypt - 22.2 KHS Qubit - 488 KHS Quark - 664.8 KHS X11 - 308.1 KHS X13 - 211.4 KHS X14 - 202.6 KHS X15 - 194.4 KHS.
The cpuminer-multi fork that we used for the test does support more algorithms than those that we tested with, we've skipped some because it is hard to find operational pools or even alive crypto coins to use some of them. So we did not test all of the algorithms such as S3, NIST5, Pentablake and a few others that are supported by the software miner. Use these numbers as a reference only for comparing to GPU mining hardware as you probably will not want to use your CPU to mine with on these algorithms anyway. The only exception being Lyra2RE, because this algorithm does provide a very decent hashrate on the CPU as compared to what you can get with a GPU miner.

To get the maximum performance use the 2.1 release of the ATI Stream SDK. 2.2 wastes CPU time, and 2.3/2.4 drop mining performance by 5-10% unless using the Phoenix phatk kernel. Note: This statement is not entirely accurate. YMMV .

A lot of nice data can be pulled from this thread to seed this section.
Might you wish to throttle CPU load a bit, so it doesn't reach 100°C, it can be done with Battle Encoder Shirase to a margin, like, -15% of available CPU cycles.
Often, the best combination to be is to throttle CPU miner to -5% AND set it to least of priority levels, so as not to choke GPU miner up.

Bitcoin - Solo Mining - Windows 7 - ATI HD 6970.
Before you do anything with Bitcoin, you need to be running the Bitcoin software. Of course, you will have visited the Bitcoin website and read everything there. The software is on the front page of the website.
I ran the software for a couple of days before I realised that I was only using the Intel processor, not my video card's GPU to generate bitcoins. Some research and I downloaded Guiminer and tried that, however whilst this provided part of the puzzle, it failed to get things working and I ended up doing the gruntwork with the command line "poclbm". Of course, since the command line programs are supplied with Guiminer, then no extra download for that is needed.
The final piece of the puzzle is getting "OpenCL" working. Guiminer does NOT recognise the latest AMD incarnation, only the previous one. I ended up installing both, so had to choose when I started the command line up, as you will see when I get to the startup command line instructions.
Software Guiminer https://github.com/Kiv/poclbm Download button on the upper right lets you download the latest .. here is a direct link to the latest at time of writing: https://github.com/downloads/Kiv/poclbm/guiminer-20110521.exe.
Here is a guide for guiminer which helped me to get started, however I had to work out the end details: http://forum.bitcoin.org/index.php?topic=10438.
Install and run Bitcoin. For mining with your GPU, you will need to run bitcoin as a server, but for the moment, we can look at the interface. There is your bitcoin wallet address, and on the bottom right, your connection status and downloaded blocks. If you want to generate coins with your CPU, then click "settings" and "generate coins". Don't expect much.
Make sure you have un-installed any conflicting video drivers and installed the latest ATI drivers for the 6970. I also ran a registry cleaner to make sure there were no confusing pointers, then rebooted.
If I had to do it over again, I would only load the "ati-stream-sdk-v2.3". Guiminer recognises it and it saves an extra flag in the command line. Reboot.
Install and run "guiminer". Have it in a convenient directory that is easy to refer to on the command line. We will be using the "poclbm" program it comes with later. What you get out of running the command line is that you can set up the configuration files. IF you have installed the stream sdk properly, then everything will work when it starts up and you will see it has found your video card in the "Device" drop down, otherwise it will complain that it can't find an "opencl" device. Select "solo" miner. Under solo utilities, enter the username and password you wish to use to log into the bitcoin server. Enter any extra flags you want to use for the device (see the hardware comparison from the previous post). Save the configuration. There are two configuration files:
First \User\ AppData\Roaming\bitcoin\bitcoin.conf Within that file, should be two lines set from guiminer. rpcuser=username rpcpassword=password.
Next \User\ \AppData\Roaming\poclbm\poclbm.ini Inside this is the solo miner configuration.
"profiles": [ "username": "user", "balance_auth_token": "", "name": "Default", "hostname": "localhost", "external_path": "", "flags": "-f60 -v -w128", "autostart": false, "device": 0, "password": "password", "port": "8332" >, ], "bitcoin_executable": "C:\\Program Files (x86)\\Bitcoin\\bitcoin.exe", "show_opencl_warning": true, "show_summary": true, "show_console": false >
The Command Line.
Open the command line.
start /D"C:\Program Files (x86)\Bitcoin" bitcoin.exe -server.
This line starts the bitcoin program as a server. The bitcoin window will open as a separate process. The directory switch means you can run the command from anywhere. Wait till a connection has been made.
start /DC:\pro\guiminer poclbm.exe --platform=1 --device=0 --user=username --pass=password.
Enter the above command line (altered for your machine of course). Note the directory switch nominates the directory - there is a space between the directory and the program executable name. Also note the --platform switch. I use 1 because I have two possible libraries as I have both the AMD and the ATI Stream libraries loaded - ATI Stream is the second one (1) that the system recognised first, so I'm staying with that. I follow it with the device switch which is the video card, and then the username and password that you set in the configuration file.
It took me a while to get it sorted, but then my Video card sprang to life and the fan went wild and you could almost feel the load. Instead of 3 M/hash per second, I was getting 350 M/hash per second.
Best of luck and I hope it works as advertised.
Update: I included a flag "-f60" in the poclbm.ini file. I found without that flag, the default of "-f30" made the priority of the poclbm process too high. I would find that after an hour or so, with the computer churning away, if I came back and wanted to do some work on the machine, it would apparently "lock" up on me and I'd have to reboot.
Update 2: The "-f60" flag has definitely improved stability with no noticeable loss of processing. The only problems I've had is when trying to play a Youtube video, when the system locks up.

Update 3: The lock-up remains no matter what "f" flag I use. It would appear that Flash video and Bitcoin mining are mutually exclusive.
Update 4: The solution I use (for the machine lockup with video playback) is to use a virtual machine for much of my work. I have Debian 64 set up as a virtual machine using Virtualbox, and I also have instructions for a Slackware VM elsewhere in this blog. Video playback works fine in the VM and it all works seemlessly. My normal use of the machine barely touches its capabilities and I can run the mining on Windows.
Update 5: Yesterday I found I had "rcp connection problems". Solutions presented on the net didn't work for me. Then I had a look at the bitcoin version I had (21) . I updated to the latest (23) and the problems went away. I also discovered that once you start the bitcoin server, you can then start the poclbm miner. It will complain about no connection etc but as soon as there is one it starts churning away.
Update 6: There was an update to my Catalyst Control Center from AMD tonight. It broke the miner I had sorted. That's the bad news - it gets better from here. In the article above, I talk of downloading the ATI stream SDK 2.3 . well, that is broke and we must move on. Install the AMD 2.4 SDK and all will be fine. In my setup, I had both - the 2.4 was platform 0 and the 2.3 was platform 1 (as reported to me). I simply changed the "platform=1" switch to "platform=0" and all was again well.
