Building an Ethereum Mining Rig (13 GPU) - 4th part

Third update to the guide "Building a Mining Rig for Ethereum". The absolute first guide to building a RX Vega 64 8gb 13 GPU Mining Rig.
Reading this guide to building a 13 GPU Ethereum mining rig requires adequate knowledge of building and running an Ethereum Mining Rig. We therefore recommend a previous view of our Guide to build a Mining Rig and related updates.

Let's immediately list the hardware used:

- Asus Mining Master X370 mainboard
- Core i5 Coffee Lake CPU
- 480 or 500GB SSD
- 32Gb Ram
- 13 GPU RX Vega 64 8Gb
- 3 x 1000W power supplies
- 1 1200W power supply
- 8Gb USB stick

In this guide we will obviously not explain how to mount the hardware of a Rig. The only notes we wish to underline are the following:

- the 1200W power supply must be the primary one on which to connect 4 GPUs and the video output for the monitor

- all the risers, as well as obviously the GPUs, must be powered through the 8-pole connections of the power supplies. We strongly advise against the use of 6-pole ports. Therefore, have the appropriate number of cables available for all connections. Risers can also be powered in pairs.

- the model of the video card used is the Asus Rog Strixx Gaming RX Vega 64 8Gb


The operating system is Windows 10 updated to the latest version available. The tool for creating installation media is available at the following link https://www.microsoft.com/it-it/software-download/windows10 to be able to use the USB key as a launcher for installing Windows 10 .

With the Asus Mining Master, the GPU risers can be connected directly to the motherboard via the USB cable, thus making one of the small components of the riser kits unusable.

After making all the connections on the motherboard, check that all GPUs are highlighted in green when the PC starts up. If not, move the USB cable on the motherboard one position. It may take at least 2 or 3 attempts.

Ethereum mining with 13 GPUs
Having solved this possible small inconvenience, let's proceed with the installation of the AMD Adrenaline 2020 drivers, always updated to the latest version, relating to the RX Vega Series.

If you want to proceed with more caution, the advice is to disconnect all the GPUs (remembering the locations of the USB cables) except one before installing the drivers.

The mining will be carried out on the Ethermine pool, our favorite, using the Claymore 15 software.


Once the download is complete, you will have to unzip the folder on the desktop and open the start.bat file contained in the Claymore folder using Notepad. The procedure is the usual one: delete the content and copy-paste the following command string:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where EthDcrMiner64.exe is the executable, -epool indicates the pool to mine and its port, -ewal is the wallet address and -epsw is the password that we leave blank (X).

In place of "your wallet address" you will have to put your Ethererum wallet and instead of worker you will enter an identification number in case you plan to build more RIGs (such as RIG1, RIG2, etc ...).

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner

Try to run mining and check that the system is stable.

In the Payouts section, after a few minutes of mining, you can decide the minimum amount of Ether to be sent to your wallet by simply entering the IP address of the RIG.

We performed the mining directly on the Ethereum address of the Exodus wallet. Coinbase is not supported.

Overclocking with OverdriveNTool
Let's proceed now with the download of OverdrivenTool at the following link: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/


For those unfamiliar with it, we recommend reading our software guide.

For those who do not intend to experiment or do not completely trust their software experience, at the following link you can view the settings on the parameters of the GPUs and the RAM of the GPUs - and other small tricks - to obtain the best possible performance without forcing the cards too much. video.

On our Youtube channel (subscribe numerous !!!) you will now be able to see the video relating to the start of mining and the one concerning the stabilization phase.

To better cool the Rig we have also installed fans for the extraction of heat as caution is never too much. Moreover, there is also an aesthetic gain.

Conclusions on the guide to build a 13 gpu ethereum mining rig.
Finally, we conclude this guide by reporting what everyone was waiting for (we do not say how long we had to wait before obtaining this result) the video link complhttps: //www.youtube.com/watch? V = k53XZn3zc9I & t = 61seto del Rig e del Mining .

We remain available for any advice, both on pools, on yield and on consumption.

Feel free to contact us in case you run into any problems where our guide to Building a 13 GPU Ethereum Mining Rig has not been completely helpful.

See you soon.

Building an Ethereum Mining Rig - Part 2

First update to the guide "Building a 6Gpu Mining Rig for Ethereum" - Let's talk about Claymore.
This update supplements and does not replace the Guide to Build a 6GPU Mining Rig for Ethereum published on our site.

The substantial differences are due to the installation of the latest version of the Windows 10 Operating System, the mining on the Ethermine pool (in our opinion simpler than Dwarfpool) and the use of the XFX RX 580 8gb GPUs.

The first variant is found in Part 4 of the guide: the environment variables are not to be entered as they will be integrated directly into the bat file to start mining.

The second variant is found in Part 7 of the guide and leads us to "mine" on a different pool using the Claymore software.
Download the latest version at the following link: https://github.com/Claymore-Dual/Claymore-Dual-Miner

Once downloaded, unzip everything on a folder on your desktop and open the start.bat file with notepad. Clear the contents and copy the following command:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where instead of "your wallet address" you will have to put your Ethererum wallet - obviously without the quotes - and instead of worker you will put an identification number in case you build more RIGs (such as RIG1, RIG2, etc ...). We opted for the eu1 pool even if some on the discussion forums believe that the us1 is more profitable.

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner


The Ethermine pool offers a very well crafted and descriptive interface. In the Payouts section, after only 5 minutes of mining, you can decide the minimum amount of Ether to be transferred to your wallet by simply entering the IP address of the RIG.

We have decided to mine directly on the Ethereum address of our Exodus wallet. It is not recommended to mine directly on Coinbase, as reported on the site itself. Sin.

Nothing should be left to chance when you decide to build a mining rig for Ethereum.
The third variant is the most difficult of all. Once you have reached Part 5 of the guide, you can decide whether to continue or follow this update / variant. If you are here it is probably because you have run into some problem that the guide does not allow you to solve.

With the latest version of Windows 10, you may run into a kernel conflict between the operating system and AMD's Radeon Software Crimson ReLive Edition Beta for Blockchain Compute drivers. This conflict will prevent you from using Atiflash after installing the drivers.

Important: Before making any changes to the BIOS, please backup each GPU.

Important: first of all flash the GPUs with the original bios if for any reason you are forced to reinstall the operating system.


Still on Atiflash.
The advice would therefore be to flash the GPUs and then install the AMD drivers. Let's say it would be because you may run into another problem this time related to the GPUs themselves. Since each video card is different from any other, the bios mod of the GPU could crash the operating system showing the classic blue screen and displaying an error related to the Atimkdag.sys file.

This could be due to the fact that some GPUs have significantly higher performance in the calculation phase than others. We could call it a factory overclock but not using them for gaming we cannot say it with absolute certainty.

Having assessed these two drawbacks, the only safe solution is to flash all the GPUs, disconnect them except for the first one, install the Blockchain drivers (plus Atimkdag patch) and launch the mining command verifying that the operating system does not go into crash in the next 5 minutes.

Turn off the rig again and connect the second GPU so on up to the sixth. In the event that one or more video cards should crash the system, disconnect them. After that, it uses DDU from the provisional mode and flashes these GPUs with their original bios. At this point, connect them again, reinstall the Blockcain drivers (plus Atimkdag patch) and start mining definitively.

All the operations related to the use of Atiflash, DDU and driver installation are reported in Part 5 and Part 6 of our guide.
A little bit of Overclocking.
You will certainly find significant differences in performance between the GPUs.

At this point all that remains is to "operate" with an overclocking software. We opt for OverdriveNtool. Our constantly updated guide is available at the following link: https://www.cryptoall.it/2019/10/12/complete-guide-to-overdriventool/

Link to the official YouTube channel for verification: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA

GPUs with modified bios will not leave much room for modification. You will have to proceed with the most extreme overclocking on those that mount the original bios; obviously always in small steps by saving the profile for each GPU. Our guide explains in detail how to do it.

Hoping to have been of help, we give everyone an appointment for the second part of the update on how to build an Ethereum mining rig in which we will explain in detail the dual mining on the Ethermine pool.

See you soon.

Dogecoin: The Meme That Turned Into A Cryptocurrency With A $300 Million Market Cap, An Important Portal To The Crypto Space

Dogecoin: The Meme That Turned Into A Cryptocurrency With A $300 Million Market Cap, An Important Portal To The Crypto Space
http://www.cypherpunklabs.com/dogecoin-the-meme-that-turned-into-a-cryptocurrency-with-a-300-million-market-cap-an-important-portal-to-the-crypto-space/
Dogecoin (DOGE), a cryptocurrency which now has a market cap of over $300 million, and at one point a market cap in excess of $2 billion, traces its origins back to a Japanese kindergarten teacher who posted pictures of her Shiba Inu in February 2010. There was one particular picture where the Shiba Inu was glaring sideways with raised eyebrows, and for some reason this picture has a similar allure as the Mona Lisa. The picture leaves it open for interpretation as to what the Shiba Inu is thinking, and people began plastering words all over the picture to indicate the dog’s thoughts. This meme was then nicknamed the doge.

https://preview.redd.it/o5a3qeyoxmk31.png?width=500&format=png&auto=webp&s=2d34893576658da1e88576d001c8a40371e65ffd
By 2013 the doge had become a full fledged viral internet sensation, and this simultaneously coincided with the rise of alternative cryptocurrencies. In 2009 the first cryptocurrency, Bitcoin, was released. Around 2013, and perhaps a little before then, people began to fork Bitcoin’s code and create all sorts of alternative cryptocurrencies.
Billy Markus, a programmer from Oregon, decided to create a cryptocurrency that would be more fun and reach a wider audience than Bitcoin. Markus teamed up with Jackson Palmer, a marketer for Adobe Systems, and they made this new fun cryptocurrency a reality. They chose the doge meme as the basis for their cryptocurrency, since it was quite popular at the time, and also adopted the algorithm from Luckycoin, where the block rewards are random like a lottery, unlike the fixed Bitcoin block rewards. Luckycoin derived its code from Litecoin, which is the #1 Scrypt cryptocurrency, and Litecoin itself is a derivation of Bitcoin.
Also importantly, Dogecoin’s Scrypt algorithm made it so miners had a low barrier to entry. Bitcoin mining had already become so competitive that only people with specialized and expensive equipment could realistically mine Bitcoin, whereas Dogecoin could be successfully mined with a GPU or even a CPU on a regular computer. This means anyone interested could easily start mining Dogecoin without spending money on mining rigs.
Further, despite being based on a meme, Dogecoin is decentralized, which puts it ahead of most of the alternative cryptocurrencies. Dogecoin has no premine and no initial coin offering (ICO), meaning all Dogecoins in circulation were distributed via mining, and the market is less prone to centralized dumping. Dogecoin uses the proof of work (PoW) algorithm which ensures the network is decentralized as well, rather than more centralized options like proof of stake (PoS).
Dogecoin launched at the exact right time to ride the dual waves of the doge meme’s popularity and the popularity of new alternative cryptocurrencies, and less than two months after launch Dogecoin had become a major cryptocurrency with a market cap in excess of $60 million.
After that, Dogecoin continued to be quite popular for a couple of reasons. As originally intended, Dogecoin ended up being a fun cryptocurrency, and a community developed around Dogecoin, especially on the Dogecoin subreddit. People began to tip each other Dogecoin constantly, especially since there were on the order of 100 billion Dogecoins, as compared to a maximum supply of only 21 million Bitcoins. This means that someone could easily tip hundreds or thousands of Dogecoins since it is not very expensive, while it is simultaneously exciting.
The general Dogecoin culture of tipping and generosity attracted many new users who had never been involved with cryptocurrency before. Newbies would first start accumulating Dogecoin tips, and then within the community they would learn how to accumulate even more Dogecoin by mining, and this represented a launching point where such users could go on to dive into the rest of the crypto space.
That is the reason why Dogecoin is still a major cryptocurrency to this day and will likely be a major cryptocurrency for the foreseeable future. The Dogecoin community is welcoming, generous, fun, and insightful. Essentially, Dogecoin is an important portal for the crypto space.

Debunking myths about mining and GPUs

E: Going to bed, will contribute more tomorrow. Thanks for the discussion!
Myth: Mining is more stressful than gaming. Fact: It depends. During the old days, this was plausible, because older GPUs (Pre-polaris) are/were bottlenecked by core clock when mining the most profitable coins. Thus, miners overclocked and overvolted these cards quite frequently, especially with cheap electricity. This meant that those cards were often run hot, pushing the limits and stressing VRM and fans quite a lot. Nowadays, ethash (Ethereum) is the most profitable algorithm for AMD cards 99% of the time, and newer GPUs (Polaris) are limited by memory bandwidth and latency. Miners can underclock core to the low 1100MHz range before seeing performance drop. To save power, miners who know what they are doing also undervolt, since it is no longer necessary to sustain a high core clock. Thus, it is quite feasible to run polaris cards below 70C at a reasonable fan speed. However, dual mining (mining more than one coin at once) does increase power consumption by up to 20%, and there are also idiots who run their polaris cards OCd while mining. With the exception of a few idiots, miners treat their Polaris GPUs pretty much the same; that is, running underclocked and undervolted 24/7 with a memory strap mod and mem OC. On the other hand, former gaming cards are highly variable in use cases. Some gamers leave their cards at stock settings, some undervolt, and some OC and/or overvolt. Most of the time, these cards are thermal cycled far more often than mining cards, which is known to weaken solder. Another thing to consider is that manufacturers have learned (somewhat) from their mistakes of putting shit tier fans in GPUs, and many fans on modern GPUs are ball bearing and/or swappable. Even some budget cards, such as MSI Armor, use decent ball bearing fans. Bottom line: the risk of buying mined Polaris cards is not as high as the risk of buying older mined cards. I would not be against buying mined polaris cards, but it's not necessarily better than buying a gamer's card instead. At the end of the day, it depends more on how the owner treated it than what they used it for.
Myth: GPUs are obsolete because of FPGAs and ASICs Fact: Mostly false. Older algorithms such as scrypt and SHA256 (lite/doge/feathebitcoin etc) are no longer feasible to mine with GPUs, but there have been multiple algorithms since then that are built to deter ASICs; most of the time it is done by making it memory-hard because designing an ASIC with high memory throughput is considerably more expensive to design and manufacture. Many devs prefer their blockchain to be ASIC resistant to avoid the concentration of power problem that Bitcoin is having nowadays, where a giant, near-monopolistic ASIC manufacturer (Bitmain) is causing a lot of (subjective) controversy. Blockchains based on ethash (Ethereum and its forks), equihash (Zcash and its forks) and cryptonight (Monero and forks) are some examples, but there are scores of other shitcoins and a few other algos that are GPU dominant. It is almost impossible that there will be another ASIC takeover, which is what was responsible for the stop in GPU demand in the bitcoin and litecoin days. Bottom line: ASICs no longer threaten GPU miners, or the demand for GPUs
Myth: Ethereum switching to Proof of Stake will kill mining soon Fact: Doomsayers have been preaching about proof of stake since late 2015. It has always been "coming soon." The fact is, the Ethereum roadmap goes from proof of work (mining) -> Casper (mining + PoS) -> Metropolis (PoS). Currently, the release date of Casper is not even announced yet, nor is it being tested in a (public) testnet. Proof of Stake might one day take over, but mining is here to stay for a while yet. Another thing to consider is that there are tons of other GPU mineable blockchains, and although Ethereum is biggest, it is certainly feasible that mining stays profitable even after Ethereum goes PoS (if it ever does). However, it is possible that profits will be low enough to discourage new miners. Bottom line: It's very unlikely. E: I screwed up the roadmap; here is a better source than me with some interesting information: https://www.ethnews.com/ethereums-vitalik-buterin-gives-keynote-on-metropolis
Myth: The current Ethereum demand spike is a bubble Opinion: Honestly, I don't know. I would not be surprised if stricter regulations on ICOs come sooner or later, which would fuck with Ether prices. There is also the inherent volatility of cryptocurrencies. However, it is also possible that blockchain technology continues to gain traction; that is, the price could just as easily go up as go down. Although it's fun to read about other people's opinions, only time-travelling wizards can tell you when it will become economical again to upgrade your poor HD5770. Bottom line: No one knows.
Myth: Miners will "steal" all the RX Vegas Fact: Only a reckless miner would buy Vegas on release, since mining performance is not known. In fact, it is possible that it can't mine at all (or at some stupidly low speed) until devs add support to existing miners. It would be even more reckless than gamers who buy without seeing benchmarks, since at least gamers can expect the games to actually run. It's also not necessarily the case that Vega will be good once miners do add support. Maybe there will be enough reckless miners to affect supply, maybe not. Of course, it is possible that miners will deplete the supply after it is demonstrated that Vega is good for mining. Bottom line: Most miners won't preorder, but it's possible that a significant number will. E: Important to remember that even if mining demand isn't high, doesn't mean that supply will be plentiful.
Myth: Nvidia cards SUCK at mining Fact: Mostly false. They USED to suck in the old pre-Maxwell days, but now they are actually more efficient at mining Ethereum and Zcash compared to AMD cards, even after both cards are undervolted. The flipside is that they (used to) cost more for the equivalent hashrate. For reference, my old 5xRX470 rig drew just under 800W when mining ETH only and hashed at 150MH/s. My current 6xGTX1060 rig draws just over half of that (<450W) and hashes at about 135MH/s. Certainly not as good in raw performance, but they are viable nonetheless, especially given the AMD GPU shortage. In fact, Nvidia cards (1060 and especially 1070) are becoming scarce as well. Bottom line: Nvidia is still the underdog when it comes to mining, but far from irrelevant nowadays.
Myth: 4GB cards will be obsolete for mining soon Fact: FALSE. The Ethereum DAG is not even 3GB yet, and won't be for a few months. The recent reports of 4GB Polaris cards slowing down soon due to DAG size is caused by limited TLB capacity, not VRAM restrictions. Polaris cards will still be able to mine ETH forks such as Expanse and UBIQ without diminished speed, and even if they are used to mine ETH, it is not that much of a performance hit at first. It would certainly not make polaris useless or undesirable for mining anytime soon. Tahiti GPUs already suffer from this issue and Hawaii is the most resistant to this issue. Have not benched Nvidia at a later epoch.
Myth: Creating miner-bashing posts on Reddit will help alleviate the GPU supply problem Fact: False, you are simply giving cryptocurrencies and mining more exposure to the general public, increasing demand.
Myth: Mining-specific GPUs will solve the shortage problems Opinion: There's not enough info to tell yet, but I am a skeptic for the following reasons. First, no display limits the resale value of the card for obvious reasons. IMO, the whole point of crypto mining from a profitability standpoint is to have a hedge against coin volatility (hardware is still worth something if the coin crashes). Otherwise it is much less effort to just buy and hold the coin. If the hardware is useless without demand from other (significant) sources, then it doesn't make much sense to buy it unless the price is extremely low. I'm sure that cost-downing the PCB and warranty will make for a cheap card, but it has to be extremely cheap and plentiful in supply, or else miners will buy whatever they can get. I could envision "failed" chips (not meeting spec of consumer editions) being stuck in miner cards, but I doubt there are enough to meet demand without ramping up production as a whole, which carries its own risks. I guess that it would help a little, but probably not solve the problems. Alternatively, since modern GPUs are bottlenecked by RAM when mining, it might be enticing to miners to have the fastest (GDDR5) RAM on the market (probably the 9gbps chips from the 1060 6G 9gbps edition, although I don't have one to test). However, my previous points still apply; buying such a card without display outputs carries a big risk. Bottom line: It's not a great idea, unless they are super cheap or use really good RAM.
Hope this helped; if you have any further questions I will try to answer them. I'm both a gamer and miner who uses both AMD and Nvidia roughly equally and don't favor one group over another. I've mined and gamed on all high end AMD GPUs since Tahiti (except Tonga) and all Pascal cards except 1050ti.

MINEDBLOCK: An advanced technological mining platform

With the emergence of all new mining platforms , the energy consumption of digital currencies gets value.
An energy organization based in the Iceland found that the energy measurements used for cryptocurrency mining in 2017 exceed annual energy and energy consumption somewhere in 200 countries. In addition, international energy and energy consumption to win the battlefield exceeds the energy consumption of some developed and developing countries.
The question faced by miners is not just a joke about the extent to which mining checks are affected. Systems like Bitcoin, Litecoin, and Dash become increasingly concentrated. The ability to manage this system is in the hands of several modern mining tasks that consume energy. To claim that the only excavator must depend on the extraction vessel. This mine contributes to centralized organizations.
At present, the mining process ends with a problem that is even greater than the response.
In the early years, the creation of digital currencies became more productive because costs had reached new highs. The rapid expansion of mines in the world led to the introduction of several new chips. MinedBlock will establish a special mining office that focuses on procuring lots of coins from the top 50 markets to ensure that customers can benefit from various revenues.
Through the planned large-scale activities, Minedblock will help improve the decentralization of coins, where there is a large pool so far that dominates the prevailing currency. MinedBlock will also move towards the decentralization dimension within its own organization by disseminating global mining information globally
MinedBlock Limited is responsible for maintaining, replacing, and increasing physical resources and will be responsible for all costs arising from past revenues in the unlikely event that the administration becomes bankrupt. In this case, the symbol owner does not need to cover all misfortune.
One of the most important standards of MinedBlock provides clarity to customers. Minedblock will be fully open to its agreement, ongoing progress and income.
All cost and income data are distributed monthly to be investigated by all symbol owners to ensure full alignment of all supervised mining management.
Each portfolio tends to be claimed by the organization and distributed to speculative committees to provide a complete picture. Mining exercises are constantly monitored and exchanged between coins because difficulties and successes vary. The main goal is to treat one by one the most extreme abilities.
Minedblock will support the use of a dual-token model, which includes benefits and security. With security tokens, users can earn passive income, while utility tags allow users to pay for various services on the platform.

MINEDBLOCK: TRANSFORMING THE MINING INDUSTRY


With all these new mining offices springing up, digital currency mining's energy consumption has additionally achieved new statures.
An energy organization situated in the UK found that in the year 2017, the measure of power used to mine cryptocurrency outperformed the yearly energy and power utilization of somewhere in the range of 200 nations. Additionally, the energy and power spent internationally on Bitcoin mining surpassed the power utilization of some developed and developing countries.
Issues that Miners are facing are not just a mere kidding issues the extent that verification of-work mining is concerned. Systems like Bitcoin, Litecoin, and Dash are winding up considerably increasingly concentrated. The ability to control these systems has been set in the hands of a couple of modern scale mining tasks that consume power. To contend, singular diggers need to depend on mining pools. Those mining pools add to organize centralization.
Mining is currently ending up all the more an issue than an answer.
In the earlier year, making digital currency turned out to be increasingly productive as costs achieved new highs. A fast worldwide extension of mining movement prompted the presentation of several new tokens. MinedBlock will make a devoted mining office which centers on mining numerous coins from inside the main 50 by market top to guarantee an assorted scope of income streams for clients to advantage from.
Through the proposed vast scale activity, Minedblock will help improve the decentralization of coins where there are as of now vast pools overwhelming the hash rates of prevalent coins. MinedBlock will likewise be progressing in the direction of a dimension of decentralization inside its own organize through worldwide dispersion of its mining information
MinedBlock Limited will accept accountability for looking after, supplanting also, growing the physical resources and will stay in charge of any expenses brought about past that of the income produced in the improbable occasion that the administration moves toward becoming un-gainful. At no time will token holders be required to cover any misfortunes if this ever happened.
One of MinedBlock's key standards is giving straightforwardness to its clients. Minedblock will be totally open with its arrangements, continuous advancement also, income generation.
All cost and income data will be distributed every month for survey by any token holders to guarantee full straightforwardness of the aggregate overseen mining administration.
Any wallet tends to claimed by the organization will be distributed inside the speculator dashboard to give full perceivability. Mining exercises will be persistently observed and exchanged between coins when the trouble and achievement rate vary. A definitive objective will be to look after most extreme proficiency consistently.
Minedblock will adopt the use of dual token model which comprises of both utility and security token. Security token will enable the users to earn passive income while the utility token will enable users to pay for different services within the platform.

A heads up to those wanting to use PCIe splitters/switches.

Well, after 129 miner restarts in SMOS I've finally gotten my 8 GPU rig mining stable for 16 hours straight. I'm using Supermicro boards in my operation to have IPMI and limit having to move rigs or monitors around to troubleshoot. Once the kinks are worked out its great! Anyways my board only has 7 PCIe slots so I've been experimenting with splitters to get me to 8 cards. Its been a long road. I started with a couple of those x1 into 4 USB cards which kinda worked if I was running less than 6 total GPUs and no more than 2 cards on each splitter. They are funky. I could run 4 on the board and 2 on the splitter for days but if I added 2 more to the board I had constant crashes. I spent an immense amount of time messing with the PCI gen, MCFG setting (base address for PCI devices) with mixed results. Finally as I gave up yesterday and put 2 cards back in another rig my x16 to 8 USB splitter finally arrived! I threw it in and hooked up 6 GPUs to it and I'll be damned it ran for 30 minutes no problem. I said screw it and grabbed 2 more cards again and had some rejected shares. Switched the slot back to PCI Gen2 and what do you know. Haven't had to reboot yet.
Obviously its known your mileage will vary using splitters like this. It won't magically make a 20 year old motherboard support more cards. But if you have a modern-ish board that doesn't have enough slots it may be the ticket. I know people have had luck with those 4 GPU splitters I'm still not sure why they were so unstable for me but hey this works. Only needing one x16 slot to run cards I may just opt for a dual CPU board and do some CPU mining as well if a new CPU only algorithm triumphs over Cryptonight.

I was the one who recommended Metaverse (ETP) and Asch (XAS) and I have found another gem

I was the one who recommended Metaverse(ETP) and Asch(XAS), I have found another gem
Metaverse/Asch at the time was an insanely undervalued project. I brought it to 4chan and recommended it, not a lot of people listened and then suddenly everyone jumped on the bandwagon.
Congratulations to all who decided to take a leap of faith, we have all made insane gains.
After discovering these insane undervalued coins, I have been doing a lot of research on the possible next NEO/OMG/ETH/ETP/WTC/XAS and to my surprise I have once again discovered a gem. I am sure this coin has been brought up before, but after really looking into it, I am convinced this is the real deal for at least a x5-10.
Now I bring you: Lomocoin (LMC) https://coinmarketcap.com/currencies/lomocoin/
The first thing most investors get turned of by when looking at this coin, is their name Lomocoin (LMC). To be fair one has to be insane to have named a project this way, it just screams low quality. However, the developers have finally taken note of this problem, and before the 31th of October, they will launch a new website and rename themselves to Lomostar(LMC). While the name is still not that good, it is much better than the former.
Lomocoin (LMC) is a decentralized location based social media application that aims to bridge the virtual world with the real world with their LMC token. Their idea is that brick and mortar stores can attract and capitalize on the foot traffic of the LMC app users by distributing LMC red envelopes around the store area, to which customers can collect and use as a discount on their products immediately by using LMC as a payment. This is only the initial stage of the product, their end goal is a vision like TRON(TRX), where virtual currency and real life world are all interconnected. Their means to get there is by attracting a large LMC user base first, and then slowly phase out into more advanced stages of their plan.
This could potentially be much more powerful than any type of online advertising for brick and mortar businesses. The money that the business spends on Lomocoin will guarantee that real people have seen and visited their business, while a Google or Facebook ad will only guarantee online clicks.
Lomocoin (LMC) already has a working product in the form of a mobile app, desktop wallet and their own block chain. The 2.0 version of their app just got released not too long ago on google playstore and it is pending approval in the IOS appstore which can be released any moment.
https://play.google.com/store/apps/details?id=com.lomocoin.lomocoin
Furthermore, Lomocoin (LMC) has a team of over 50 people, this is just downright insane for a project this size. The team has has been working together since 2013 and they have experience in technical research, business operations, and blockchain tech. They are one of the first teams in China that did blockchain research and development. The founder of Lomocoin (LMC) is called Xiong Lijian, he has helped developed and manufacture the world’s first 28nm Bitcoin and Litecoin dual algorithm chip SF3301 and the world’s first SF100 double miner. As you can deduct, the technical expertise of this CEO is on a whole other level.
CEO’s Twitter: https://twitter.com/xlijian Right Hand Man: https://twitter.com/liuji_daoma Community manager: https://twitter.com/M1lanooo
What’s potentially most valuable about Lomocoin (LMC) is their long term end game vision. Having followed Lomocoin (LMC) for quite a while, it is safe to say that their team comprises of a group of people who are able to deliver on the things promised. Except for the mobile app, the Lomocoin team is also currently beta testing their own online exchange called Xstar and what’s’ even more important is that they have a research team in place called F5. This will all come live in early November. Xstar will facilitate bitcoin/fiat to LMC conversion and for now, all we know about F5 is that it is already working with over 100 small and medium sized businesses, and they are already heavily collaborating with universities in providing blockchain training sessions as well as deep research into blockchain developments and technology. (This information was only recently shared in their telegram group and still mostly unknown to public)
https://xstar.io https://imgur.com/a/q9z2R
Unlike most of the Chinese coins in the above list, that can somewhat be compared to a western equivalent, Lomocoin (LMC) is a real wildcard in this space. Lomocoin (LMC) is unique in its value proposition, and you can’t just assign a minimum value on it based on its western counterpart.
So how do we best value Lomocoin (LMC) in this scenario? To do this we will have to look at social media apps, and the one that comes closest to Lomocoin (LMC) is called MOMO (陌陌). MOMO is not a coin, but a very popular Chinese social media stock listed on Nasdaq. MOMO is a free location-based services instant messaging application for smartphones and tablets. The app allows users to chat with nearby friends and strangers. MOMO’s market cap as of this moment of writing is valued at 6 billion $. LoMocoin (LMC) has all the elements MOMO is offering and even more by providing a gamification and business element to it with location based red envelope hunting with friends or strangers. I think the name Lomocoin is taking a direct stab at MOMO, hence the similarity. Lomocoin is currently as of this moment of writing valued at only 11 million$ , once it starts to gain traction and become more well known you can guarantee that you will never see this level again as it is a far cry from what it should be worth at least with their own product, blockchain as well as wallet.
https://finance.yahoo.com/quote/MOMO/
If it reaches even 1% of what MOMO is doing currently Lomocoin (LMC) should be valued at 60 million $. Lomocoin (LMC) can best be compared with coins like Tron (TRX) and Monacoin(MONA), who are both currently sitting at around 200 million $ valuations with nothing except a whitepaper and hype. The same can easily happen with LMC once they start pushing their marketing at the end of October and early November.
This is a hidden gem and severely undervalued. However before investing money please take your time to do your own research as well, as I cannot guarantee that this will definitely moon. I'm just of very strong believe that this is a VERY undervalued coin for what it has to offer at this moment.
Lomocoin (LMC) is currently available for trade on bittrex and coinexchange and will be expanding into more exchanges in the near future.
If you think that this information is valuable it would be awesome if you can consider donating a small amount to help me out in my daily life. If you would like to subscribe to my small and unknown newsletter shoot me an e-mail [email protected]
I hope that you all have a lot of gains in the future, below are my addresses if you want to donate! Thanks a lot in advance, any amount will be immensely helpful to me.

The power behind Viacoin's merged mining

Let's talk about the power behind merged mining. (Auxiliary proof of work - AuxPOW)
Very simple: you mine for instance Litecoin and can mine at the same time Viacoin without losing hashrate.
But we are going to make an example.
Look at the Hashrate of Viacoin let say it is around 50 TH/s. https://chainz.cryptoid.info/via/
We take the Antminer L3+ as the miner for the whole Viacoin network.
The Antminer L3+ produces around 500 MH/s and it uses 800 watts.
This means that we need 100.000 Antminers to come at a network hashrate of 50 TH/s.The whole system of 100.000 Antminers are using 80.000.000 watts. (800 watt x 100.000)
These 80.000.000 watts x 24 Hours will result in 1920000 kWh.Let say the power costs are $0.15 per kWh is a total-cost of $12000 per HOUR !
To run the Viacoin network on your own with 50 TH/s will give you a electricity bill of $288,000.00 per DAY ! And than we even not talked about the equipment costs.
https://www.coinwarz.com/calculators/viacoin-mining-calculato?h=50000000000.00&p=80000000&pc=0.15&pf=0.00&d=329994.01552825&r=0.03906250&er=0.00008391&btcer=3714.30000000&hc=0.00
In the link i put in all the correct data and you can see it for your self, what it actually will costs to run the whole Viacoin network.
--------------------
At a price as Viacoin is today, you will lose 105 M dollar in 1 year to run the network.
If Viacoin was not AuxPOW the price for 1 Viacoin should be around 2400 dollars each, just to make the mining profitable.
And with this in mind you can see the enormous benefits behind Viacoin's merged mining.
It is not only secure but it also brings sustainability, and provides, that you are paying a fair price for your coin.
Not a single company has benefits to give Viacoin an artificial price, that's why you pay for Viacoin $0,30 and not $2400,-
And with a lot of cryptocurrencies there is a lot of money involved, and the actual buyers are paying the price.
When you buy Viacoin you know for sure that the price is originated by supply and demand, and personally with other cryptocurrencies i have so my doubts.
Other article that you might be interested in to read about merged mining:
  1. https://medium.com/altcoin-magazine/merged-mining-how-dual-mining-of-cryptocurrencies-works-98323ea57529

And than we can talk about the huge energy-costs of mining, and people will say yes but proof of stake and masternodes......
The problem with those algorithms is that it creates an elite-status to early investors, those people are untouchable until they decide to step out, and there even can be SIMILARITIES found with a ponzi-scheme, i am not saying it is a 1 on 1 ponzi.
Let say someone paid 5 dollar for a masternode and the 10th man paid $500 and the 10000th man paid $500000 dollars because this is what happens, the first people are untouchable and only generates money, the last is paying a big price and can wait 300 years to earn his investment back.Same is for proof of stake it only generates money for the team behind the coin or early investors.
It only can be considered fair and efficient when the pay-out for those algorithms is ZERO.
----------
Than you have people that say, yes but than cryptocurrency in general is a ponzi, well...
Do you consider gold as a ponzi?
I know for sure those people who bought gold, didnt get any extra gold by only holding it.And the same you can apply on POW.
1.WORK PAYS
2.DETERMINATION PAYS
But we were talking about the energy costs.
---------
Energy costs.
A lot of people are talking about the energy waste of proof of work systems, it is a point, but their is one big ''but''.
Can you name me one industry where there is no environmental footprint?
I personally realy dont know.
When you drive a car, metal must mined and gasoline must come out of the ground, when you in a plain and go on vacation etc.. etc..
Not going to deep in this stuff because it is endless.
But those same people are saying that proof of work is a waste of energy, while they fly around the world, and than they suddenly don't care about the environmental footprint they as a human leave behind and the flight industry they support?
I am in fact for a greener world, but for that, there a change is needed not only in the world industry but also in the world economy.
I see AuxPOW as a green step to an ''existing problem'' because it thrives only on the energy from other blockchains, and not use electricity on it's own.
And when the blockchain industry evolves, their will be new solutions, and when Bitcoin, Litecoin or any other can implement such new solutions, to this problem, than also Viacoin can implement it.

Thank you for reading.

Try and convince me that Vericoin and Verium Reserve don't offer the best solution for Crypto as a means of value transfer

I'd like to start a serious conversation here:
BTC and LTC have the impossible task of being a store of value and a cheap to send cryptocurrency. Oh and they are centralized as fuck with their ASICs. Litecoin doesn't suffer from the same long transaction times and expensive transactions as Bitcoin, but with Charlie Lee out of the picture, it's hard to be super confident that they'll reign supreme.
Vertcoin is ASIC resistant, which is cool, but you have to invest in expensive miners to participate in securing the network. So it's pretty much just an LTC clone that's ASIC resistant (for now). Am I right?
Groestl Coin. Honestly, haven't looked much into them as that name is awful. I don't see how you're going to be used by the masses when no one can pronounce the name.
NANO is a neat idea. But the block lattice structure of their "Not Blockchain" is far from proven in a stress test. Plus, they traded decentralization for speed and cheapness of transactions. They are banking on merchants to run nodes to secure the network and keep transactions humming along.
With Vericoin, all you need is a computer with an open wallet to earn juicy interest of around 6%. And with Verium all you need is a decent CPU to mine and earn VRM. And by leveraging both technologies on a single chain, you have the best of both worlds. A cheap to use, and quick currency in Vericoin and a stable strong network secured by Verium (no other POS coin will have the security benefits of Vericoin because of the security offered from Verium). If you ask me, the only thing holding Vericoin and Verium Reserve back is that no one knows about them and no one wants to do the research to learn why a dual chain structure is best.

NiceHash versus MiningPoolHub Guide

NiceHash v. MultiPoolGuide - mods please sticky.
Hi everyone,
I have been seeing quite a few questions on this sub about NiceHash and MultiPoolHub, and which one is better. Since I have and currently use both, here is my analysis:
NiceHash is by far the easiest to use and get into mining. It benchmarks your GPUs and CPUs (if chosen) to figure out what algorithms would be the best to sell your hash power to buyers. In other words, people pay you using Bitcoin to have your system mine for them.
NiceHash charges a 4% pool fee for those who use their own wallets or 2% if you use NiceHash wallets - it should be noted that their wallet uses a sliding scale of withdrawal fees. If you don't make a whole lot of BTC, then it's best to use the external wallet due to a lower fee to receive your BTC.
NiceHash uses a Pay Per a Share method of payment. This is advantageous to miners, because the risk of not finding a block is distributed to the pool and will be paid for each share submitted. The fee also covers the expenses of the development of their nifty software interface, servers, staff, etc.
The disadvantage is when you take into account the high fees. NiceHash tends to use Claymore miner software which can take up to 2% more of your income as DevFees. This can total 6% of your income.
MiningPoolHub is an actual pool where you can mine various coins. It does not have any nifty easy to use interfaces like that of NiceHash, but they do have some software listed to help make algorithm switching easier. They also have simple auto-switching, which I personally use. You can set your Claymore Miner for example to mine both Ethhash and SiaCoin at the same time (please see batch script example below).
MiningPoolHub's fees are significantly less, .9%; if you use their auto-exchange feature it will be about 1.1%. Now what is cool about MiningPoolHub, is that you can get paid in any coin type they support (e.g. Bitcoin, Litecoin, Ethereum, et al). Please be aware though, certain coins like Bitcoin can have high withdrawal fees (e.g. .0003 BTC) and making their fees higher than NiceHash's, unless you can wait until you have .009 BTC at a minimum (the fees for other coins tend to be a lot less than Bitcoin). - so choose your payment type wisely. Don't forget that if you use Claymore, the DevFee still applies with MiningPoolHub as well; however their fee will still be less than NiceHash's, assuming you do your math right for the withdrawal settings.
A few personal notes: 1. Don't use NiceHash's client from NiceHash proper. I tend to find I can make more money using the NiceHash legacy miner, Alison known as Dillon's Fork. The NiceHash client from the site itself doesn't dual mine with the 1.7.x version and 2.x tends to be flakey with mixed brand GPUs. 2. MiningPoolHub hub's fee for withdrawing BTC is kinda high. So I would advise using Litecoin if you plan on cashing out via Coinbase for US residents, since you shouldn't directly mine Ethereum to Coinbase. 3. If you want to dual mine Ethhash (meaning using their simple auto-switching) and SiaCoin, please use my example batch script below, because for whatever reason their 20xxx port for SiaCoin doesn't seem to work and they don't really advertise this 17xxx port for Sia.
Claymore batch to dual mine Ethhash and Sia:
---- Begin batch, do not copy this line ------
setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100
EthDcrMiner64.exe -epool us-east.ethash-hub.miningpoolhub.com:17020 -ewal username.workername -eworker username.workername -esm 2 -epsw x -allpools 1 -allcoins 1 -dpool stratum+tcp://hub.miningpoolhub.com:17022 -dwal username.siaworkername -dpsw x -dcoin sc
--------- End Batch, do not copy this line ---------
---- Don't forget to use -etha 1, if you have cards less than a 1050 Ti in performance, and mess around with -dcri valued to get the best results. I didn't include those flags, biecause I have no clue what you are using to mine with. Also, do not forget to set the default algorithm in the hub section to Ethhash and set whatever you named your Sia worker's name to, to SiaCoin or it may not be mining anything at all.
One other note, please change the stratum addresses to the ones most appropriate for your location.
Edit: grammar. I really shouldn't be posting with a few hours of sleep thanks to teething kids :-/

WA+WFN gold mining mode, the tide players of the new era!

WA+WFN挖矿掘金模式,新时代的弄潮儿!

最近一段时间,整体区块链市场都一直处于熊市和低迷状态,但平台通证和通用积分却依然备受投资人的欢迎,其中FT和ONE为代表,平台交易量在短短几天内不断刷新记录,FT交易量号称超过顶级交易所,而BigONE在Alpha公测期间,平台交易额达到40亿美元,位居全球前列。发展速度和势能着实让人感到吃惊。足以可见“交易即挖矿”模式带来的威力是相当惊人的。
Recently, the overall blockchain market has been in a bear market and in a downturn, but the platform token and the common points are still popular among investors, including FT and ONE, and the trading volume of the platform has constantly refreshed records in just a few days. FT trading volume claims to exceed the top exchanges, and during the Alpha beta, the platform transaction volume of BigONE reached 4 billion US dollars, ranking the world's forefront. The development speed and potential energy have really surprised everyone. It is enough to see that the power of the “transaction is mining” model is quite amazing.
但随之而来的问题也是让我们不能忽略的,不管是FT还是ONE,传统的“交易即挖矿”模式在缺乏自律的运营环境下,就表现出利益倾斜、有失公允,收割投资者等不当行为,在没有制衡的区块链泡沫之中,注定会以失败告终。
But the problems that come with it are also something we can't ignore. Whether it is FT or ONE, the traditional “transaction is mining” mode, in the absence of self-discipline operating environment, it shows that interests are titled, unfair, harvest investors and other improper behavior. In the blockchain bubble without checks and balances, it is doomed to fail.
而WA+WFN新模式的出现,将衍生出更多有趣、可靠的机制,基于这种机制,能真正解决了传统交易即挖矿带来的一致性问题,从而让矿工们靠着"挖矿"收获意想不到的成果!
The emergence of the new WA+WFN model will lead to more interesting and reliable mechanisms. Based on this mechanism, it can truly solve the consistency problem caused by traditional transaction is mining, so that the miners can rely on "mining" "to harvest unexpected results!
首先,WFN通证与传统的比特币、莱特币不同,WFN拥有自己的核心技术,基于全新的第四代区块链技术,其技术特性远远要超出前者,随着WFN全球生态圈的逐步完善,其商用价值也将变得完美无缺。
First of all, WFN is different from traditional Bitcoin and Litecoin. WFN has its own core technology. Based on the new fourth-generation blockchain technology, its technical characteristics are far beyond the former, with the gradual improvement of WFN global ecosystem, its commercial value will also become perfect.
其次,Wafcoin通证交易平台发行的平台通证WA,采用参数矩阵、双牌照合规合法运营、适度拥抱监管等优势,创新推出平衡交易挖矿模式,即WA设有规模调整机制,持有WA越多挖矿相对就越快,WA设有规模调整机制,持有WA越多挖矿相对就越快,凡持有WA通证的用户均可可享受平台每天交易收益高额分红,主节点享有OTC商家资格Wafcoin为用户提供安全,高效的体验,为用户节省交易成本,为合伙人提供稳定,长久的收益平台。
Secondly, WA, the platform token issued by Wafcoin Token Trading Platform, adopts the advantages of parameter matrix, compliance and legal operation with dual license, and moderately embrace the supervision, and innovatively introduces a balanced transaction is mining mode, that is, WA has a scale adjustment mechanism. The more you hold the WA, the faster the mining is. The users who hold the WA token can enjoy the high dividends of the daily trading income of the platform, master node has OTC merchant qualification. Wafcoin provides users with a safe and efficient experience, saves transaction costs for users, and provides a stable, long-term revenue platform for partners.
WA作为Wafcoin通证交易平台发行的平台通证,可以用于兑换比特币、莱特币、以太坊等主流通证,传统的比特币、莱特币、以太坊等主流通证都是基于区块链3.0技术发行的通证,而国石WFN通证则是基于第四代区块链技术发行的全新通证,技术方面我们之前已经提到过,在价值上WFN流通于全球各大主流平台,并与WA交易挖矿模式并行,不难预见未来国石WFN通证将会有无限的可能。
WA is a platform token issued by the Wafcoin Token Trading Platform, which can be used to redeem the main circulation tokens such as Bitcoin, Litecoin and Ethereum. Traditional Bitcoin, Litecoin and Ethereum are issued based on blockchain 3.0 technology. And the National Stone WFN Token is issued based on the new generation of the fourth generation of blockchain technology, the technical aspects we have already mentioned, in terms of value, WFN circulates in the world's major mainstream platforms, and in parallel with the WA transaction is mining model, it is not difficult to foresee the future National Stone WFN Token will have unlimited possibilities.
用户完全可以通过WFN的交易,得到WA,反之客户也可以通过WFN的交易产生利润,而且免费获得WA,同样可以得到利润,获得双重利润如此简单,可以说是当今行业内最炙手可得的掘金模式,弄潮儿。
Users can get WA through WFN transactions. On the contrary, customers can also generate profits through WFN transactions, and get WA for free. They can also get profits. It is so simple to get double profits. It can be said that it is the best gold mining model and tide player in the industry today.

Discussion: How blockchain/crypto will get adopted in the near and far future

​So I'm new to crypto/blockchain and I've been learning about it over the last few months and thinking about how it will be used in the future and the problems I foresee that may hold it back from more mass adoption (and how clearing up some of those problems might also have some adverse effects on it)
Firstly, let's separate blockchain applications into 3 main categories:
  1. Currency: bitcoin, monero, litecoin, etc
  2. Specific Application: sia, golem, storj, gridcoin, etc
  3. Platform: eth, neo, etc
Let's start with the first:
Currency: bitcoin, monero, litecoin, etc
This is probably the most straight forward usage of the block chain and is pretty easy to understand. If the supply of coins is truly limited and if there is wide adoption of a particular coin, the value of a coin will go up (like bitcoin). But people keep saying that the real enemy of crypto is fiat currency and they imagine a world where crypto replaces fiat. But for that to happen, Crypto has to be very stable and it cannot wildly fluctuate as it does now. Maybe there will come a day when there is a stable, semi-private crypto used a national currency and the supply of coins is transparent on a public blockchain and is always backed by something so the current issues with fiat don't exist (like countries printing an unlimited supply of money and causing inflation). But until then, crypto will always need to be pegged to something and that something will probably need to be a fiat currency. Also, it will probably crush everyones moon lambo dreams but crypto will probably become a lot more stable. Only then is it feasible to price things in cryptocurrency or pay people in crypto.....otherwise you will always have to pay using a converted fiat to crypto amount and I imagine someone who gets paid in crypto won't like that sort of volatility on his paycheck.
Other issues: Speed and transaction cost. To a consumer, visa/mastercard are instant transactions, they extend you some credit for free (for one billing cycle and then they rape you), in some countries they give you rewards to use their services (I get almost $100 cash back every month) and to the consumer, there is no transaction fee (though it is built into the cost of the product). I think any coin for mass adoption needs to meet these criteria.
Specific Application: sia, golem, storj, gridcoin, etc
I feel this section of blockchain will have the most trouble in adoption in the near future unless something is done about certain aspects of it. Firstly, all the projects of this type are really clunky and not even close to being user friendly enough for mass market adoption.
Once this gets fixed, I see another issue with these types of blockchain applications. These blockchains will needs to have two tokens associated with them....one can be a volatile coin that is traded and used/mined to secure the network but there needs to be a more stable token that is used to buy the services that the blockchain is providing. For example, for storage if I need to use sia coin to buy my storage services, and the sia coin shoots up for some reason (as many coins do), does a customer who is using sia's service suddenly have to pay double for the same service? That will never work, especially in enterprise where things have to be budgeted months or years in advance. Also, I'm not sure how the economics of this dual token system will work.....how one token will stay separated from the other and how the miners will be incentivized to secure the network if the internal token price doesn't have a speculative component. Maybe some of the proceeds from the actual business will have to get baked into the miner tokens or something. I am not sure if this is already being done. I think that's how gas works on the Neo blockchain but I'm not too sure. If it is then just ignore everything I said about this.
Another problem I see with these blockchain projects is that right things are all up in the air and very speculative and so their tokens are being traded at high values on promises of riches and lambos what not. But once this business gets established and they realize that say the sia project is generating a revenue of X, it will become evident that the the tokens have no business having a market cap of 10X or 100X and these tokens will settle at their true value. And once that happens, I don't know if miners will find it profitable to mine and secure their network.
Platform: eth, neo, etc
I understand this category the least but I know that this category will probably take off at a higher level (govt, infrastructure, etc) and doesn't really need the masses to adopt it. Smarter people at higher levels will adopt these platforms (or build their own) and build their applications on them and the people will eventually interact with a simple front end, just like we currently do. Again, I don't understand where the value of the tokens comes from and eventually what will incentivize miners to secure these networks. I imagine there will be a two token system (like neo and gas or eth and gas) but the relationship between them is still a little unclear to me (which one feeds which one, etc).
Anyway I just wanted to get some of that out of my head and onto text. It helps me understand things better as well. I hope smarter people can maybe discuss how they think some of these issues will pan out in the future.

One week with the USB DualMiner dogecoin miner. It's been working great!

So I received the DualMiner bitcoin/litecoin (SHA/scrypt) USB miner device on Monday. I've had it running nearly 24/7 since then and it's been working flawlessly giving me a hashrate of 70khs.
It has been able to mine dogecoin with no issue.
For $110 after shipping, it's still too expensive, but the technology works.

[Troubleshooting] I have a super weird build with 2 GPU's, and I'm getting no video output from either. The commenter that fixes my problem will be gilded.

(I posted this question to /litecoinmining (and /dogemining), but only got one answer. Just to be sure I want a few more opinions before I go ahead)
I've bought an R9 270, and I have it set up inside a milk crate (litecoin miners know what I'm talking about). The milk crate is sitting next to my gaming computer (I bought a very, very long USB riser to attach the GPU), and I have plugged the gaming computer's PSU into both the powered riser and the new GPU's 6-pin slot. The R9 270 is meant to serve as a full-time bitcoin miner, and is drawing it's power from my gaming computer.
However, when I tried to turn on the computer (with both the 6850 and the R9 270 plugged in), almost everything would work fine. I have checked and made sure the CPU, graphics cards, and the hard drive are working fine. However, my monitors would get no input from both the 6850 and the motherboard's HDMI plug. (My motherboard is an Asrock H61M/U3S3)
I then unplugged the R9 270 + it's 1x to 16x riser, and both PSU cords. When I booted the computer back up, I miraculously started getting video input again.
One last thing: Whenever I run the PC while the R9 270 is plugged in, the PC shuts down as soon as I press the power button. Not sure if this is relevant at all, but just thought this could help anyone looking for a solution.
What I've done so far:
What should I do to restore video to my PC so that I can get the mining card set up?
My Gaming Computer's Partlist:
CPU: Intel Pentium G620 2.6GHz Dual-Core Processor
Motherboard: ASRock H61M/U3S3 Micro ATX LGA1155
Motherboard Memory: Corsair 4GB (2 x 2GB) DDR3-1333
Memory Storage: Seagate Barracuda 500GB 3.5" 7200RPM
Video Card: Sapphire Radeon HD 6850 1GB Video Card (Plus the previously mentioned R9 270)
Case: NZXT Phantom 410 (Black/White) ATX Mid Tower Case
Power Supply: Antec Basiq Plus 550W 80+ Certified Semi-Modular ATX Power Supply
TL;DR Installed a R9 270 into my gaming computer as a 24/7 bitcoin mining card. But when I plug it in, I don't get any video from neither my motherboard, the R9 270, nor my 6850. What do I do to restore video?

Hobby Scrypt Mining Build

Hi, I have been interested in mining for a while here and use to be really into bitcoin but the variety that scrypt mining offers is intriguing. I want to get into mining litecoins and other scrypt based coins but I am unsure what to buy. I have everything you need for a setup except the miner. i was looking at asic miners like the Grindseed or the DualMiner since they were more feasible with my setup. if you have any other ideas or different miners to use i would appreciate it. im not into making money on it and i would like to spend under $200-$150
