The EWBF CUDA Zcash Miner has a built-in developer fee that is set at 2%, meaning that every 10 minutes the software will switch to a different pool and mine for the developer some shares and then get back to mining for you. The author of the software claims speeds of about 250 H/s for Nvidia GTX 1070 while the NiceHash EQM miner does currently about 220 H/s on the same GPU. Our quick tests showed a hashrate of 235-240 H/s average (up to 250 H/s) on stock GTX 1070, so still slightly faster, but not as much as you may want it to… then there is the dev fee as well and it seems that we are seeing somewhat more rejects than, especially when switching to mine for the dev fee. So while this may be an interesting alternative for users willing to mine outside of NiceHash, the actual performance that you may get poolside may not be much different than with what is currently the fastest implementation from NiceHash (taking into account the dev fee and the rejected shares)…
If you’re reading the newbie’s guide to Ethereum mining and have a GPU that’s powerful enough to make it worthwhile, we’re going to assume you’re running Windows, so we’ll focus on mining Zcash on that platform.
Ran the same settings on both miners and it’s more like 4-5% more than EWBF. 1080 + 1070 =~1020 Sol/s on Bminer with 60% Power limit and 350 W at the wall. On EWBF it’s ~970 Sol/s for both. The 1080 gets the biggest boost on Bminer about 10% ~574 Sol/s with 60% power limit. I’m mining on Flypool which only shows the effective hash rate, so it will take a while to be accurate but it seems legit.
6. It is recommended that you install applications such as MSI Afterburner in order to control the card’s fan. In its default mode, the power is low and it allows the card to reach a temperature of 70-80 degrees Celcius (normal when playing occasionally but not healthy when it comes to a machine running 24-hours a day).
Buying gear and mining cryptocurrency with it allows you to own an income-producing asset in the gear itself, with aftermarket resale value holding up very well and even appreciating. GPUs purchased for mining in 2015 and 2016 were often sold at a profit in 2017 due to high demand in the market!
Zcash, or ZEC, is a currency that developed from Bitcoin, with the addition of anonymity. While in Bitcoin’s blockchain, anyone can see the transactions between all the addresses and see each address’s balance, with Zcash it is possible to make transactions without revealing the balance of a wallet (which represents an address).
After letting your newly setup miner run for about 20-30 minutes, you can check the pool to confirm you shares are being counted and see some pool-side statistic of your mining progress. On the top right of the Flypool Zcash homepage (shown above) you can enter your Zcash wallet address and click on Check Status to get to your own wallet personal statistics page.
I think I will end this guide at this point for now as it is getting to be quite long. While I originally intended to cover fine tuning and going over other optional arguments that the EWBF miner can use, I think I will wait and make this a two part guide. For now this Part 1 covers the basic setup and configuration of getting the EWBF miner running and shares being submitted to a pool. Since it will usually take some time before reaching a pools minimal payout period anyway, especially for just one or two cards, we have some time.
The answer? Difficulty. By automatically adjusting the computational difficulty of solving a block, the Zcash blockchain is able to maintain 2.5-minute intervals. You’ll notice that difficulty closely tracks hashrate, and it, too, has seen exponential growth this year:
Freedom Miner is a Zcash Miner beast and is defaulted to mine ZEC out of the box, however changing currencies is a breeze before or after you receive the rig. During purchase simply provide us with your wallet addresses for the coins you wish to mine and we’ll send your rig pre-configured. Don’t have wallet addresses yet? No problem, we can ship your rig with our system defaults.Freedom Miner comes with a standard 3-prong US style power cord, but other standard power supply cables are compatible as well.

Earlier today Zcash (ZEC) went live as expected and people are already starting to mine it, some of them probably are still not aware of the slow start with very small block rewards initially. Regardless, with what is available as miners at the moment there are pretty much two places where you would want to go for mining if you still haven’t done so. The first one for CPU mining and CUDA mining is Flypool that uses a modified version of NiceHash’s stratum miner available for download here CPU/CUDA miner for Flypool.
If the invalid shares were to exceed 3%, or stay at a constant 2%, you should check first to making sure you are connected to the flypool server nearest you. If you look on their homepage they will list different addresses for servers located in different parts of the world. The next thing to check would be back on the miner to make sure you are not seeing any errors being generated there. There are too many possible scenarios to cover all in this introductory article, so I will leave any in-depth troubleshooting for a later guide.
Keep in mind that your profitability will depend mostly on your electricity and internet costs. As such, it’s common to find large mining operations close to power plants, as those ventures tend to strike up B2B rates with the plants themselves to ensure profitability. But don’t worry, it’s likely that your conditions could lead to a reasonable ROI (Return on Investment) as well. Just make sure to calculate the ins and outs of your situation before you make a sizable investment.
You can also use a hardware wallet such as Trezor, Ledger Nano S, or Jaxx, a popular supported web wallet. You can even mine directly to exchanges that have support, which is primarily what I’ve been doing since November 2016 (I’ve been mining to Bittrex).
Claymore has updated his ZCash AMD GPU miner to version 12.5 adding support for the ZCash forks (altcoins using the same Equihash algorithm) as well as doing some more improvements to the miner. The latest version comes with improved fans management for latest drivers and Polaris cards, added shares-per-GPU statistics when “s” key is pressed, addend an option to use a password for remote monitoring as well as included EthMan v3.0 which supports passwords and email notifications. This is currently the preferred solution by most miners mining ZEC or other coins based on the Equihash algorithm for AMD OpenCL GPU mining rigs, the miner does not yet have support for Nvidia GPUs. Nvidia miners can go for some of the available options for CUDA mining such as the nheqminer, excavator or EWBF’s CUDA Zcash miner for mining coins using the Equihash algorithm on their hardware.
Not everyone has access to a computer, however, and not everyone has the time, knowledge or patience to start mining Zcash on their own, especially since there is no Graphic User Interface (GUI) Miner available yet. If you want to mine on your own computer, but need a little push to do so, you’re in the right place. But if you’re looking to profit from Zcash mining with no effort at all, this guide will do the trick.
To achieve this, we need open source miners for anyone to use. The Zcash Company sponsored the Zcash Open Source Miner Challenge operated by Least Authority. The Winners and Runners Up of this challenge are listed on the submissions page.
Right click on the bat file called “flypool” and hit Edit. The file will open in Notepad. Paste what you’ve copied from the flypool website. I’m going to update my server to “us1” instead of “eu1,” and I’m also going to remove the “—cuda_devices” language at the end. This language is used if you want to designate mining only to certain devices (for example, if you want to game with one GPU and mine with the other two). If you want to mine with all devices, you can delete the —cuda_devices designation.
(ZEC) This is what happed to me. I lost one “Pending” payment, and that “Pending” last for at least 6hrs. When I woke up in the morning, that Pending was gone, no payment. I checked all the top miners, they have the same thing, I don’t know if they notice or not. Many times, the number for “Balance” freeze for couple hrs. I’m pretty confidence to say that, nanopool does steal coins. However, I tried flypool (steal hashes), and Dwarfpool, and turns out this pool is ok to mine.
GPU Graphical Processing Unit, a GPU (or commonly just referred to as a graphics card) was previously the dominant way of Bitcoin mining. It was way beyond the efficiency of a CPU and plenty common among computer users to gain widespread adoption. With the increase in the difficulty it has recently become too inefficient for most to continue mining with GPUs as their electric bills now compete with the value they generate. For futher details, please see our hardware page.
Mining and holding crypto is similar to the old adage of buying low and selling high, except for the fact that most buyers don’t know how to do technical analysis, so they buy and sell at the wrong times. They buy high during parabolic price increases and sell low during what could be normal price corrections on continued upward trends.
