Second, I worked out a way to benchmark using different DAG (directed acyclic graph) file sizes. Chances are the other clients can do this as well, I just didn’t work out how. I felt it important to test various DAG file sizes to show future performance as well. As the DAG file size increases, so too does the difficulty. A new DAG is generated for each epoch around every 30,000 blocks and right now it is estimated that this will happen every 4 days or so. For example, at the start of the month Ethereum was at DAG epoch #126 and now we’re already over #130 and next month we should hit #140, but don’t hold me to that.
If this seems too difficult or too much of a hassle then you are a wuss!  Just kidding! ?   Even though an ethereum minging rig is fun and a lot like having a money tree, the process of tuning it and making sure it’s cranking away is not the easiest thing to do.  That is why cloud mining exists.  If you want to take a look at cloud mining and what it would cost, click here.
Also, this calculator shows that DAG size will only reach the point to render 3GB unusable around the end of this year (block ~6.9 million, epoch 231), not epoch 180 like shown in the article. Not sure which to trust…
In order to mine correctly, we’re going to need to run two programs. The first is ethminer, which talks to your GPUs and does all the hashing work. The second is geth, which talks to the network and keeps up-to-date with the blockchain. Ethminer is written in C++ and comes from the project cpp-ethereum, whereas geth is written in Go and comes from the project go-ethereum. We’ll talk about installing both, and then follow up with how you’ll run each together.
Die Nennung in diesem Abschnitt bedeutet nicht die Billigung dieser Dienste und verfolgt lediglich den Zweck eines Vergleichs von Bitcoin Cloud Mining. Es gab eine enorme Anzahl an Betrug im Bitcoin Cloud Mining.
Note : If you plan to sell your GPUs after their (profitable ?) use, then you should definitely include the popularity of the GPU in your criteria. For example, 8Go-GPUs are said to attract gamers in the second-hand market.
This is another excellent budget alternative to the Radeon R9 295X2. It is the second highest in terms of the hash rate among the GPUs for mining Ethereum, of course, coming after the Radeon R9 295X2. The Radeon HD 7990 comes with a hash rate of 36 MH per second, which draws 375 watts of electric power from the wall. Each of these GPUs is estimated to net in a return of $469.40 in one year. Its initial investment, however, is much lower than the R9 295X2. Available at Amazon, this GPU is one of the best cost-conscious alternatives for those who want to mine Ethereum. With 56% as its profit ratio per day, this Ethereum mining GPU has a payback period that slightly exceeds one year. It has a daily cost that is estimated at $1.08, which is evidently lower than the R9 295X2’s. That brings its daily return to $1.29, while the cost per MH/s is $18.89.
Custom BIOS. Custom BIOS’ are trickier. While it’s easy to use a tool such as AtiFlash to flash your GPU, bare in mind that it is risky. You will also need to find a BIOS that is suitable for your GPU unless you’re proficient at tweaking it yourself with a tool like PolarisBiosEditor. However, this can have the largest gain. For example, for the RX480 a custom BIOS can raise its hash rate to 30Mhs+ which is a considerable 30% improvement!

Now replace “” with your Ethereum Wallet address (which starts with 0x…) so copy that from your other text file and paste it here.  Then replace “” with any name you would like to create for your miner.  We’ll use “MiningRig1” for our example, so you now have:  
Pro-tips: check out the following GPU’s: AMD Rx 470/480 Rx 570/580, AMD R9 range, HD 7990 / 7950 (if used cards are available, try to get them from a gamer instead of a miner, with a warranty if possible).  For Nvidia, look at the 1060 / 1070 / 1080 series cards.  As with everything, do your own due diligence to evaluate GPU’s based on their hashrate, power requirements, availability and price. 
Miner sind auch dafür verantwortlich, dass niemand im Netzwerk eine doppelte Transaktion tätigt oder gegen andere Regeln des Blockchain Protokolls verstößt. Solche Regeln werden vor der Erschaffung einer Blockchain festgelegt. Alle Transaktionen müssen dem zuvor festgelegten Protokoll entsprechen.
As other have said, no direct impact. But some altcoins are popular for dual mining with ethereum. If those coins go to ASIC, it will force miners to recalculate what makes for a profitable mining operation.
ASICs allow miners to use hardware made specifically for Bitcoin Core or other SHA-256 algo coins. An ASIC has benefits over CPU, GPU and FPGAs due to being designed for one specific task. They are able to mine BTC at a higher hash rate (speed of processing transactions) than CPUs, GPUs and FPGAs.  Several manufacturers produce their own ASIC chips and miners. For this part of the Bitcoin Core mining guide we will use the current top miner on the market the Bitmain AntMiner S9.
Motherboard:  You’ll need a little luck and possibly some magic or a custom UEFI to find a motherboard that supports six to seven video cards. The Intel Z87 and Z97 chipsets for LGA1150 processors offer a pretty good bang for the buck as they are being cleared out to make room for the newer Intel Z170 and Z270 motherboards for the LGA1151 processors. Our favorite board right for GPU mining is the MSI Z170A GAMING PRO CARBON as it has the ability to run SEVEN GPU’s at a time when using the latest UEFI for $129.99 on Amazon. That board is starting to get hard to find, so alternatives would be the newer ASUS PRIME Z270-A at $139.99 shipped or the MSI Z170A Gaming M5 for $149.99 shipped. People are actually mining with eight video cards on the ASUS PRIME Z270-A motherboard thanks to an M.2 to PCIe 3.0 x4 adapter than can be had for $8.95 shipped. The ASUS Prime Z270-P for $105.99 shipped also works with 8 GPUs if you use two of the M.2 to PCIe 3.0 x4 adapters.
ETH mining seems to be still buggy and not optimized, a lot of people still seem to have problems, hopefully this will be resolved with updates of the miner software. So try both versions of the ethminer, the CUDA one also supports OpenCL and CPU mining.
At this point, we’re done with the essentials. If you’ve done everything correctly, you should be able to reboot and watch your rig automatically start mining shortly after the Windows desktop loads. There are a couple more steps that may be important to you, though.
Das Prinzip ist sehr einfach: Anstatt sich selber Mining-Equipment anzuschaffen und zu betreiben wird die Rechenkapazität in der Cloud gemietet bzw. teilweise sogar gekauft. Die Cloudanbieter stellen die Infrastruktur hierfür Verfügung und betreiben dann auch die Miner. Bei einem Mietvertrag ist der Betrieb meist direkt mit inkludiert, sollte Rechenkapazität gekauft werden, bekommen die Cloudanbieter einen Teil der neu geschürften Bitcoins. Somit muss keine eigene Hardware beschafft und betrieben werden.
Full-Nodes und Miner nehmen Transaktionen an, überprüfen und leiten sie anschließend weiter. Jedoch können ausschließlich Miner dafür sorgen, dass neue und unbestätigte Transaktionen in einem Block zusammengefasst und für alle Ewigkeiten in einer Blockchain, als letztes Glied einer Kette, gespeichert werden.

CoinYourBit, Google loves to mark all the mining software as a possible malware… we are constantly asking to get the site reviewed and get these false warnings removed. The source code is linked in the article for anyone that may have some concerns, you can compile yourself or download some of the other pre-compiled binaries.
Die Zeit als zu berücksichtigender Faktor in der Berechnung von Wirtschaftlichkeit und Break-Even. Im Grunde stellt sie das Maß aller Faktoren her. Strom wird nach kW pro Stunde berechnet, die Hashrate pro Sekunde, die Hardware nach ihrer tatsächlichen Laufzeit bzw. Arbeitszeit und der Wert eines Coins hat sich in Tagen, Monaten oder Jahren hoffentlich vervielfacht.
I reckon just try running Claymore and see what it says. I’m not up to date on Ethereum mining but I heard that the ETH blockchain has gotten too big to sync normally. I don’t know how miners are handling that but presumably some kind of pruning or other solution is used.
The remaining question is the significance of the network difficulty. Imagine the guessing game of between 1 to 10, the difficulty that one can guess it right is the chance of 1/10. We say the equivalent of 1 guess is equal 1 hash, the difficult is 10. In average, a player needs to guess 5 times before a guess is hitting the correct number. However, if this guessing game is having too many guesses happening in a short time, the correct guess may happen too fast. The guessing game’s maker (the whole network) will automatically adjust the difficulty, adjusting from 10 to 100, to reduce the correct guess happening too fast. This is the essence of using the network difficulty to control how fast a correct guess can happen.
