In a recent press release cryptocurreny mining market Nicehash revealed that its payment service was hacked and its BTC payment wallet was emptied. While the company did not reveal the exact amount lost, users on Reddit spent the better part of today worried as the service was initially "under maintenance" for 12 hours amidst suspicious transactions on the blockchain that saw 4,736.42 BTC taken from Nicehash and their Nicehash internal wallets reporting zero balances. The company is currently investigating the precise amount stolen, though estimates around the web put it north of $66 million USD worth of the popular cryptocurrency (at time of writing 1 BTC = ~$13970.50).

Users that mined to an external wallet for an additional fee are out unpaid balances less than 0.01 BTC, but sadly users that mined to an internal wallet have potentially losts hundreds or thousands of mined bitcoin. Also, purchasers of the Nicehash mining service may have lost the BTC that they paid into the service for alt coin hashing power.
"We are fully committed to restoring the NiceHash service with the highest security measures at the earliest opportunity.
We would not exist without our devoted buyers and miners all around the globe. We understand that you will have a lot of questions, and we ask for patience and understanding while we investigate the causes and find the appropriate solutions for the future of the service. We will endeavour to update you at regular intervals."
Nicehash is further recommending that users of its internal wallets change all of their online passwords (especially any that were similar to the one they used on the site) as a precaution.
The full press release is available here.
In all, it is a devastating hack that is another in a series of high profile crypto currency heists that have traditionally left users out money and the company destroyed. Nicehash has indicated that they have reached out to and are cooperating with the relevant authorities, but unless they are able to find the individual(s) responsible and recover the massive amount of bitcoin it is not looking good.
I hope that the bitcoin is able to be recovered or at least that Nicehash is able to do the right think and compensate its users from its own funds.
This high-profile attack further illustrates the need to use safe bitcoin storage practices and to always hold your own private key in an offline wallet (hardware or paper or at least encrypted software wallet you control at a minimum) for long term storage of funds. Your crypto currency is only truly yours when you alone control the private key(s) and you should only transfer and keep coins on other servers (e.g. exchanges) for as long as it takes to transfer them to your bank or as short a time as possible when trading.
What are your thoughts on this? Did you have money in a Nicehash wallet or unpaid mining balance? Do you plan to venture forth and mine on your own?

In addion to the AMD-based mining graphics cards based on the RX 470 Polaris silicon that have appeared online, NVIDIA and its partners are launching cryptocurrency mining cards based on GP106 and GP104 GPUs. Devoid of any GeForce or GTX branding, these cost controlled cards focused on mining lack the usual array of display outputs and have much shorter warranties (rumors point at a 3 month warranty restriction imposed by NVIDIA). So far Asus, Colorful, EVGA, Inno3D, MSI, and Zotac "P106-100" cards based on GP106 (GTX 1060 equivalent) silicon have been spotted online with Manli and Palit reportedly also working on cards. Many of these manufacturers are also also planning "P104-100" cards based on GP104 or the GTX 1070 though much less information is available at the moment. Pricing is still up in the air but pre-orders are starting to pop up overseas so release dates and prices will hopefully become official soon.
These mining oriented cards appear to be equipped with heatsinks similar to their gaming oriented siblings, but have fans rated for 24/7 operation. Further, while the cards can be overclocked they are clocked out of the box at reference clock speeds and allegedly have bolstered power delivery hardware to keep the cards mining smoothly under 24/7 operation. The majority of cards from NVIDIA partners lack any display outputs (the Colorful card has a single DVI out) which helps a bit with ventilation by leaving both slots vented. These cards are intended to be run in headless system or with systems that also have graphics integrated into the CPU (miners not wanting to waste a PCI-E slot!).
|Base Clock||Boost Clock||Memory (Type)||Pricing|
|ASUS MINING-P106-6G||1506 MHz||1708 MHz||6 GB (GDDR5) @ 8 GHz||$226|
|Colorful P106-100 WK1/WK2||1506 MHz||1708 MHz||6GB (GDDR5) @ 8 GHz||?|
|EVGA GTX1060 6G P106||1506 MHz||1708 MHz||6GB (GDDR5) @ 8 GHz||$284?|
|Inno3D P106-100 Compact||1506 Mhz||1708 MHz||6GB (GDDR5) @ 8 GHz||?|
|Inno3D P106-100 Twin||1506 MHz||1708 MHz||6GB (GDDR5) @ 8 GHz||?|
|MSI P106-100 MINER||1506 MHz||1708 MHz||6GB (GDDR5) @ 8 GHz||$224|
|MSI P104-100 MINER||TDB||TBD||6GB (GDDR5X) @ ?||?|
|ZOTAC P106-100||1506 MHz||1708 MHz||6GB (GDDR5) @ 8 GHz||?|
Looking at the Nicehash Profitability Calculator, the GTX 1060 and GTX 1070 are rated at 20.13 MH/s and 28.69 MH/s at DaggerHashimoto (Etherium) mining respectively with many users able to get a good bit higher hash rates with a bit of overclocking (and in the case of AMD undervolting to optimize power efficiency). NVIDIA cards tend to be good for other algorithms as well such as ZCash and Libry and Equihash (at least those were the majority of coins my 750 Ti mined likely due to it not having the memory to attempt ETH mining heh). The calculator estimates these GPUs at 0.00098942 BTC per day and 0.00145567 BTC per day respectivey. If difficulty and exchange rate were to remains constant that amounts to an income of $1197.95 per year for a GP106 and $1791.73 per year for a GP104 GPU and ROI in under 3 months. Of course cryptocurrency to USD exchange rates will not remain constant, there are transactions and mining fees, and mining difficulty will rise as more hardware is added to the network as miners so these estimated numbers will be lower in reality. Also, these numbers are before electricity, maintainence time, and failed hardware costs, but currently mining alt coins is still very much profitable using graphics cards.
AMD and NVIDIA (and their AIB partners) are hoping to get in on this action with cards binned and tuned for mining and at their rumored prices placing them cheaper than their gaming focused RX and GTX variants miners are sure to scoop these cards up in huge batches (some of the above cards are only availabe in large orders). Hopefully this will alleviate the strain on the gaming graphics card market and bring prices back down closer to their original MSRPs for gamers!

What are your thoughts on all this GPU mining and cryptocurrency / blockchain technology stuff?

Over the last several weeks, we have been experimenting with the most recent GPU-shortage-inducing coin mining craze, with Ken's article as a jumping off point. On a recent podcast, I mentioned the idea of running a community coin mining group that would be used as a way for individuals to contribute to PC Perspective. I received several requests for the wallet and setup information to make this happen, so I thought it would be worth while to gather all the necessary links and info in a single location.
We have been running a Patreon campaign for a couple of years now on the site as a way to provide an avenue for those readers and viewers that find PC Perspective a useful resource to the community and directly contribute. It might be because you want to keep the PCPer staff stable, it could be because you use an ad blocker and are looking for a way to even things out, etc. But there are always some that don't have the ability or desire to sign up for a new service so contributing your empty GPU cycles is another option if you want to donate to the PCPer team.
How do you do it? Ken has created a step by step guide below - thanks for your support in this and all of our previous endeavors!
- Bitcoin: 1HHhVWPRpCUst9bDYtLstMdD7o5SzANk1W
- Ethereum: 0xa0294763261aa85eB5f1dA3Ca0f03E1B672EED87
For those of you who may be curious to try out this mining stuff on your personal computer, we would recommend looking into the NiceHash application.
For those of you who haven't read our previous article, NiceHash is a service that connects buyers of GPU mining power to sellers who have spare hardware that they are looking to put to use.
As a warning, if you are planning to mine please be aware of your power consumption. To get a good idea of this, you can look up the TDP of your given graphics card, multiply that wattage by the hours you plan to mine, divide by 1000 to translate from watts to kilowatts, and multiply that by the rate you pay for electricity (this can be found on your power bill in cents per Kilowatt/Hour in the US). (So it's watts*hours*days/1000*kw/hr rate - Thanks CracklingIce)
Given the current rates of value for these cryptocurrencies, power is a small portion of the gross profit made by mining, but it is important to be aware of this before you are presented with a huge power bill that you weren't expecting.
First, download the latest version of the NiceHash miner application from their website.
After your download has finished, extract the ZIP file and load the NiceHashMiner.exe program.
Once the application has been launched and you've accepted the terms of the EULA, the NiceHash Miner will start to download the appropriate mining applications for your given hardware.
Note: during this installation process, your antivirus program might detect malware. These miner executables that are being downloaded are safe, but many antivirius programs flag them as malware because if they are found on your PC without your permission they are a telltale sign of malicious software.
After the installation process is completed, you be brought to the main screen of the application.
From here, choose the server location closest to you, add the Bitcoin address (in this case: 1HHhVWPRpCUst9bDYtLstMdD7o5SzANk1W), and choose a unique worker name (up to 7 characters long).
From here, hit the benchmark button, select the devices you want to mine on (we would recommend GPUs only, CPUs don't earn very much), and hit the Start button.
Once the benchmarking is done, you'll be brought back to the main screen of the application where you can hit the Start button.
Once you hit the start button, a command prompt window will launch where you can see the miner at work (this can be hidden from the NiceHash setting pane), and you can view the stats of your computer in the original NiceHash application window.
And that's it, your computer will now be mining towards the PCPER community pool!
Astute readers of the site might remember the original story we did on Bitcoin mining in 2011, the good ole' days where the concept of the blockchain was new and exciting and mining Bitcoin on a GPU was still plenty viable.
However, that didn't last long, as the race for cash lead people to developing Application Specific Integrated Circuits (ASICs) dedicated solely to Bitcoin mining quickly while sipping power. Use of the expensive ASICs drove the difficulty of mining Bitcoin to the roof and killed any sort of chance of profitability from mere mortals mining cryptocurrency.
Cryptomining saw a resurgence in late 2013 with the popular adoption of alternate cryptocurrencies, specifically Litecoin which was based on the Scrypt algorithm instead of AES-256 like Bitcoin. This meant that the ASIC developed for mining Bitcoin were useless. This is also the period of time that many of you may remember as the "Dogecoin" era, my personal favorite cryptocurrency of all time.
Defenders of these new "altcoins" claimed that Scrypt was different enough that ASICs would never be developed for it, and GPU mining would remain viable for a larger portion of users. As it turns out, the promise of money always wins out, and we soon saw Scrypt ASICs. Once again, the market for GPU mining crashed.
That brings us to today, and what I am calling "Third-wave Cryptomining."
While the mass populous stopped caring about cryptocurrency as a whole, the dedicated group that was left continued to develop altcoins. These different currencies are based on various algorithms and other proofs of works (see technologies like Storj, which use the blockchain for a decentralized Dropbox-like service!).
As you may have predicted, for various reasons that might be difficult to historically quantify, there is another very popular cryptocurrency from this wave of development, Ethereum.
Ethereum is based on the Dagger-Hashimoto algorithm and has a whole host of different quirks that makes it different from other cryptocurrencies. We aren't here to get deep in the woods on the methods behind different blockchain implementations, but if you have some time check out the Ethereum White Paper. It's all very fascinating.
