Mining 101: How To Use NiceHash To Earn Bitcoin

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.

Mining ERC-918 Tokens (0xBitcoin)

GENERAL INFORMATION

0xBitcoin (0xBTC) is the first mineable ERC20 token on Ethereum. It uses mining for distribution, unlike all previous ERC20 tokens which were assigned to the contract deployer upon creation. 0xBTC is the first implementation of the EIP918 mineable token standard (https://eips.ethereum.org/EIPS/eip-918), which opened up the possibility of a whole new class of mineable assets on Ethereum. Without any ICO, airdrop, pre-mine, or founder’s reward, 0xBitcoin is arguably the most decentralized asset in the Ethereum ecosystem, including even Ether (ETH), which had a large ICO.
The goal of 0xBitcoin is to be looked at as a currency and store of value asset on Ethereum. Its 21 million token hard cap and predictable issuance give it scarcity and transparency in terms of monetary policy, both things that Ether lacks. 0xBitcoin has certain advantages over PoW based currencies, such as compatibility with smart contracts and decentralized exchanges. In addition, 0xBTC cannot be 51% attacked (without attacking Ethereum), is immune from the “death spiral”, and will receive the benefits of scaling and other improvements to the Ethereum network.

GETTING 0xBITCOIN TOKENS

0xBitcoin can be mined using typical PC hardware, traded on exchanges (either decentralized or centralized) or purchased from specific sites/contracts.

-Mined using PC hardware

-Traded on exchanges such as


MINING IN A NUTSHELL

0xBitcoin is a Smart Contract on the Ethereum network, and the concept of Token Mining is patterned after Bitcoin's distribution. Rather than solving 'blocks', work is issued by the contract, which also maintains a Difficulty which goes up or down depending on how often a Reward is issued. Miners can put their hardware to work to claim these rewards, in concert with specialized software, working either by themselves or together as a Pool. The total lifetime supply of 0xBitcoin is 21,000,000 tokens and rewards will repeatedly halve over time.
The 0xBitcoin contract was deployed by Infernal_Toast at Ethereum address: 0xb6ed7644c69416d67b522e20bc294a9a9b405b31
0xBitcoin's smart contract, running on the Ethereum network, maintains a changing "Challenge" (that is generated from the previous Ethereum block hash) and an adjusting Difficulty Target. Like traditional mining, the miners use the SoliditySHA3 algorithm to solve for a Nonce value that, when hashed alongside the current Challenge and their Minting Ethereum Address, is less-than-or-equal-to the current Difficulty Target. Once a miner finds a solution that satisfies the requirements, they can submit it into the contract (calling the Mint() function). This is most often done through a mining pool. The Ethereum address that submits a valid solution first is sent the 50 0xBTC Reward.
(In the case of Pools, valid solutions that do not satisfy the full difficulty specified by the 0xBitcoin contract, but that DO satisfy the Pool's specified Minimum Share Difficulty, get a 'share'. When one of the Miners on that Pool finds a "Full" solution, the number of shares each miner's address has submitted is used to calculate how much of the 50 0xBTC reward they will get. After a Reward is issued, the Challenge changes.
A Retarget happens every 1024 rewards. In short, the Contract tries to target an Average Reward Time of about 60 times the Ethereum block time. So (at the time of this writing):
~13.9 seconds \* 60 = 13.9 minutes
If the average Reward Time is longer than that, the difficulty will decrease. If it's shorter, it will increase. How much longer or shorter it was affects the magnitude with which the difficulty will rise/drop, to a maximum of 50%. * Click Here to visit the stats page~ (https://0x1d00ffff.github.io/0xBTC-Stats) to see recent stats and block times, feel free to ask questions about it if you need help understanding it.

MINING HARDWARE

Presently, 0xBitcoin and "Alt Tokens" can be mined on GPUs, CPUs, IGPs (on-CPU graphics) and certain FPGAs. The most recommended hardware is nVidia graphics cards for their efficiency, ubiquity and relatively low cost. As general rules, the more cores and the higher core frequency (clock) you can get, the more Tokens you will earn!

I've had enough of my rx 480 screwing me over... upgrading to a GTX 1060 or perhaps something else?

Build Help/Ready:

After two full days of attempting to fix my PC, I've come to the seeming conclusion that it's a hardware problem. Repeated and consistent BSODs, typically atikmpag.sys, though sometimes IRQL or other video related ones are occuring. It's not software - three times I've safe-mode DDU clean uninstalled AMD drivers and reinstalled the drivers. I even did a clean windows install. It's not the motherboard or CPU - the machine runs fine with the graphics card removed. It's not the cable or monitor - BSODs occur on every monitor I try, HDMI, VGA and DVI. It's not the registry - I increased tdrdelay to 8 seconds and then 16 seconds and it still occurs. It's probably not the power supply - I've undervolted and underclocked the card only to experience BSODs still.
As I narrow it down forum post by forum post, I've come to the conclusion: the rx480 is a POS. I guess it's time to bite the bullet and hop over to Nvidia's well supported 1060s, which since the bitcoin crash are more affordable than ever.
What is your intended use for this build? The more details the better.
Gaming and browsing, no weird video/streaming shit. Here's the games I (might) play, graded in general by demand on the GPU:
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)
60fps minimum on the games I play. As you can see only a few of these games are particularly demanding (the last few), and I'm perfectly comfortable playing on low/medium settings to achieve 60fps for that. The rx 480 in the early part of its life could sometimes manage these (and to be sure, it was also dependent on the rather shitty optimisation of PUBG/GTA), but can no way achieve them now. So just having that consistency is enough for me.
What is your budget (ballpark is okay)?
Already have the pieces. No more than £250, but I see 1060s available for around £140. Therefore it's more about value for money and long-term considerations than the money itself right now.

Thanks.

What is EIP:918?

EIP:918 is an Ethereum Improvement Proposal for standardizing mineable token distribution using Proof of Work.
The primary driver behind the standard is to address the very broken ICO model that currently plagues the Ethereum network. Token distribution via the ICO model and it’s derivatives has always been susceptible to illicit behavior by bad actors. New token projects are centralized by nature because a single entity must handle and control all of the initial coins and all of the the raised ICO money. By distributing tokens via an alternative ‘Initial Mining Offering’ (or IMO), the ownership of the token contract no longer belongs with the deployer at all and the deployer is ‘just another user.’ As a result, investor risk exposure utilizing a mined token distribution model is significantly diminished. This standard is intended to be standalone, allowing maximum interoperability with ERC20, ERC721, and future token standards.
The most effective economic side effect of Satoshi Nakamoto’s desire to secure the original Bitcoin network with Proof of Work hash mining was tethering the coin to real computing power, thereby removing centralized actors. Transitioning the responsibility of work back onto individual miners, government organizations have no jurisdiction over the operation of a pure mined token economy. Oversight is removed from an equation whereby miners are providing economic effort in direct exchange of a cryptographic commodity. This facilitates decentralized distribution and establishes all involved parties as stakeholders. The ERC918 standard allows projects to be funded through decentralized computing power instead of centralized, direct-fiat conversion.
The Ethereum blockchain in its current state exists as a thriving ecosystem which allows any individual to store immutable records in a permission-less, invulnerable and transparent manner. Recently, there have been proposals to mitigate some initial ICO investment risks through the introduction of the DAICO model that relies on timed and automated value transfers via the smart contract tapping mechanism. However, this does not align a token smart contract as a non-security and still has the potential to put investors at risk if not implemented carefully, relying on centralized actors to be fair and community intended. Allowing users of the network direct access to tokens by performing computations as a proof of work supplies allows any smart contract to distribute a token in a safe and controlled manner similar to the release of a commodity.
As of 2017, all Ethereum token distribution methods were flawed and susceptible to Sybil attacks. A Sybil attack is a form of computer security attack where one person pretends to be many people with multiple computer accounts in order to manipulate a system in a malicious way. ICOs and airdrops are highly susceptible to these type of attacks so there is no way to verify that all ERC20 tokens distributed by the deployer were doled out fairly or unfairly. Proof of Work distribution is resistant to Sybil attacks. This means that ERC918 tokens are among the first trustless Ethereum tokens in the world. The distribution of ERC918 tokens is fair because they are allotted via an open, decentralized mathematical algorithm (that anyone can view on the mainnet blockchain) and not a centralized human monarchy.
ERC918’s first incarnation (and inspiration) was the 0xBitcoin project that launched in early 2018. Since then, several projects have realized the standard in innovative and creative ways. Catether (0xCATE) erupted early and additionally mints payback tokens during transfer operations to offset gas costs. 0xGold and 0xLitecoin each implement the first on-chain merge-mining with 0xBitcoin and the Mineable Gem project extends the standard onto a non-fungible collectible artifacts, whereby each gem has a unique mining difficulty. The Mineable project is a newer initiative that provides users with the ability to create mineable ERC20 tokens on-chain without writing a line of code and includes a virtualized hashing artifact market that allows miners to purchase on-chain vGPUs to improve mining difficulty and rewards.

Video card errors, driver crashes, can't isolate cause

Symptoms: I have a GTX 770. Periodically while I'm using it (from every 30 seconds to 30 minutes) the screen freezes, goes black, and then comes back with a system tray warning appearing notifying me that Windows has recovered from a display driver crash. While browsing the web, text sometimes renders a little fuzzy and there are dots on the screen. When I test the card with OCCT's error test, it racks up hundreds of thousands of erros in minutes.
I also had a couple problems with it about a year ago just after I bought it. The display drivers would crash once every few days, but it would crash badly and I'd have to restart Windows. This only happened a few times over a couple weeks and then went away, then I had no problems for a year, so I never did much about it. Then suddenly problems began happening again.
Troubleshooting: I've updated the Nvidia drivers to the latest (and again since new versions have come out while dealing with this). I even updated the card's BIOS. Nothing changed.
The card isn't being stressed when this happens, there's nothing open other than the browser, there's almost no load at all. In fact when I do try to play a game on it, it seems to work OK. Temperatures are low, less than 45C. It's virtually dust-free and well ventilated. I've tried reseating it several times, nothing changed. I see no signs of any bitcoin mining malware or anything like that.
The card is overclocked out of the box. I tried underclocking it, down to the reference card values and even below that, nothing changed.
I do not get any of these symptoms when using the Intel integrated graphics in the CPU, or when using an older PCI-Express card in the same slot. I tried putting the 770 in an older PC too, and I saw no problems there and OCCT reported 0 errors after several minutes. It seems only to be this card in this computer.
I saw a suggestion that memory errors could be responsible, but my RAM seemed to pass memtest86 with no problems.
The power supply is 860 watts, seems to be perfectly adequate for a single GPU.
System specs:
I can't figure out what to blame here. Everything seems to operate without errors independently, but not together. Any suggestions?
Edit: The errors do not occur with the generic driver that Windows installs, but it does occur with both the older driver supplied by Asus (327.23) and the latest one (340.52). But the card is also not being fully utilized with the generic driver, getting 2 FPS in OCCT instead of 60.
Edit 2: I've been obsessed with fixing this enough that I even reinstalled Windows to see if a fresh installation with absolutely nothing except for the drivers and OCCT would still produce errors. It did work once upon a time, after all. OCCT still reported errors, the drivers began crashing again. Restoring Windows was no picnic either, upgrading to 8.1 sabotages the whole restore process when you're trying to start from a Windows 8 installation disk.
I didn't mention that I already RMA'd it to Asus. They sent the same one back (or at least I think they did, it has the same serial number and no explanation came with it). I said maybe I'm dumb and there's nothing wrong with it after all, but after more and more testing, I can't figure out what else it could be.
