Gigahash is trying to kill Bitcoin. Devs need to wake the fuck up and do something.

Evidence:
-Here we find Gigahash using a double-spending attack against BetCoin dice, to fund their operations:
https://bitcointalk.org/index.php?topic=327767.0
-Anyone can now see they're 50% of the network.
Most importantly however:
Someone with a large amount of hashpower has done what I've been warning of for months: The block-solution withholding attack.
Eligius has lost 300 BTC to a block-solution withholding attack:
https://bitcointalk.org/index.php?topic=441465.msg7282674#msg7282674
This is VERY big news. It requires a very large mining capacity owner. Furthermore, the attacker also loses some money when committing a block-solution withholding attack. In this case, because the attacker was caught in time, the attacker lost 200 BTC that the Eligius operator now chooses not to send to him.
Why would someone risk losing such a large amount of money to attack a harmless wellmeaning pool? The only way I can think of that an attacker can have a financial incentive to engage in a block-solution withholding attack against a small pool like Eligius is when the attacker owns a pool themselves. The operator of Eligius has warned that he believes other small pools are under attack as well. The problem is that the attack can not be stopped, as the attacker will simply reconnect with a different IP address eventually. What's going to happen now is that all pool operators are going to be forced to implement tests to constantly check whether someone is carrying out a block-solution withholding attack against them.
It's 100% clear to me that Gigahash is trying to destroy Bitcoin.
If Devs choose to do nothing about the Gigahash problem, then they're complicit.

Classifying PoW Coins based on Hashrate

I wanted to find out whether the rankings of Coinmarketmap has any basis on Hashpower of different projects and I was kinda surprised at the results.
Bitcoin is at the very top with it's Hashpower in Exahashes, ETH was in Terahash range, which is significantly lower.
I noticed that other projects like Dash, Digibyte, and DogeCoin had Hashrate in Petahasg ranges which blew me off.
I couldn't believe ETH has less Hash than Doge. Also I noticed Monero had Hashrate hovering around Gigahash range, which lower than Ravencoin.
Is looking at Hashrate a good way to vet Cryptos? Need your inputs smart folks.

How to prove you are a time traveler using the bitcoin blockchain

It turns out there are more applications of bitcoin than simply revolutionizing every economic system ever conceived.
It is also possible to prove you traveled through time with the help of the hashing mechanism behind our favorite blockchain.
As a thought experiment, consider the following calculation:
Now, if you as a civilization are able to use the energy of your host star, that makes you a type II civilization on the Kardashev scale.
My challenge to the universe and its type II civilization time travelers is simple:
Produce an empty block with around 32 leading zeros in the coming year and we’ll take notice.

Congratulations r/Bitcoin! You have created a decentralised discussion! (P.S. Ghash.io is EVIL)

We get it. Ghash.io's hashrate is high. If your post can't fit into one of these threads about ghash.io, it's probably not adding anything substantial to the conversation.
EDIT: Decided that instead of whinging, I will try to help the community access the information that is most relevant to them. Before posting a new thread, check if one of these may be relevant.
EDIT 2: Now that Ghash.IO has made an official press release claiming that they will not act maliciously, I am going to get some well deserved shuteye. I am sure the saga will continue on without me.

How much Power it takes to create a Bitcoin?

How much Power it takes to create a Bitcoin?
https://preview.redd.it/q8fybks5d3r31.png?width=1024&format=png&auto=webp&s=0d9836d98582d8652a82a99333d37b2885d4116e
Bitcoin Mining Costs Vary by Region
To perform a cost calculation to understand how much power it takes to create bitcoin, first, you’d need to know electricity costs where you live. In 2017, the Crescent Electric Supply Company did a state-by-state breakdown of how much it costs to mine a single bitcoin. Louisiana came in as the cheapest location at $3,224, while Hawaii was the most expensive at $9,483. As of September 2018, bitcoin’s exchange rate was valued at about $6,700 for a single bitcoin, which shows that doing the work in an area where energy costs are very low is important to make the practice worthwhile.
Calculating the Cost
There are lots of different bitcoin mining computers out there, but many companies have focused on Application-Specific Integrated Circuit (ASIC) mining computers, which use less energy to conduct their calculations. Mining companies that run lots of ASIC miners as businesses claim they use one watt of power for every gigahash per second of computing performed when mining for bitcoins.
At this rate, the bitcoin network runs at 342,934,450 watts — roughly 343 megawatts. Calculations based on EIA data reveal that the average U.S. household consumes about 1.2 kilowatts of power, meaning that 343 megawatts would be enough to power 285,833 U.S. homes.
That’s quite a lot of energy — for a frame of reference, that equates to about a third of the homes in San Jose, California. Since 1 watt per gigahash/second is pretty efficient, it’s likely that this is a conservative estimate. Also, a large number of residential users take more power to run their miners.
BITCOIN may be a useful way to send and receive money, but cryptocurrency doesn’t come for free. The community of computer-based miners that create bitcoins uses vast quantities of electrical power in the process. The electric resource-heavy process has led some experts to suggest that bitcoin isn’t very environmentally friendly. Therefore, using SOLAR ENERGY to mine Bitcoin is considered more suitable for people.

Does anyone else agree that Bitmain needs to stop flooding the market with more and more and more machines. It’s almost impossible......

Does anyone else agree that Bitmain needs to stop flooding the market with more and more and more machines. It’s almost impossible to turn a profit with S9’s now!! I know you’re in business to make money but stop being greedy and share the wealth. In the past 7weeks profits have gone down 56% due to the number of workers(machines) added. I’m going to stick it out as long as possible but i can’t be the only deciding at what point they get unplugged. From January to current the number of machines added to JUST Slushpool has gone from 88,000 to 120,000. CRAZY!!!!

Bitcoin Mining Profitability: How Long Does it Take to Mine One Bitcoin in 2019?

When it comes to Bitcoin (BTC) mining, the major questions on people’s minds are “how profitable is Bitcoin mining” and “how long would it take to mine one Bitcoin?” To answer these questions, we need to take an in-depth look at the current state of the Bitcoin mining industry — and how it has changed — over the last several years.
Bitcoin mining is, essentially, the process of participating in Bitcoin’s underlying security mechanism — known as proof-of-work — to help secure the Bitcoin blockchain. In return, participants receive compensation in bitcoins (BTC).
When you participate in Bitcoin mining, you are essentially searching for blocks by crunching complex cryptographic challenges using your mining hardware. Once a block is discovered, new transactions are recorded and verified within the block and the block discoverer receives the block rewards — currently set at 12.5 BTC — as well as the transactions fees for the transactions included within the block.
Once the maximum supply of 21 million Bitcoins has been mined, no further Bitcoins will ever come into existence. This property makes Bitcoin deflationary, something which many argue will inevitably increase the value of each Bitcoin unit as it becomes more scarce due to increased global adoption.
The limited supply of Bitcoin is also one of the reasons why Bitcoin mining has become so popular. In previous years, Bitcoin mining proved to be a lucrative investment option — netting miners with several fold returns on their investment with relatively little effort.
bitcoin mining hardware
Mining Hardware
The mining hardware you choose will mostly depend on your circumstances — in terms of budget, location and electricity costs. Since the amount of hashing power you can dedicate to the mining process is directly correlated with how much Bitcoin you will mine per day, it is wise to ensure your hardware is still competitive in 2019.
Bitcoin uses SHA256 as its mining algorithm. Because of this, only hardware compatible with this algorithm can be used to mine Bitcoin. Although it is technically possible to mine Bitcoin on your current computer hardware — using your CPU or GPU — this will almost certainly not generate a positive return on your investment and you may end up damaging your device.
The most cost-effective way to mine Bitcoin in 2019 is using application-specific integrated circuit (ASIC) mining hardware. These are specially-designed machines that offer much higher performance per watt than typical computers and have been an absolutely essential purchase for anybody looking to get into Bitcoin mining since the first Avalon ASICs were shipped in 2013.
When it comes to selecting Bitcoin mining hardware, there are several main parameters to consider — though the importance of each of these may vary based on personal circumstances and budget.
Performance per Watt
When it comes to Bitcoin mining, performance per watt is a measure of how many gigahashes per watt a machine is capable of and is, hence, a simple measure of its efficiency. Since electricity costs are likely to be one of the largest expenses when mining Bitcoin, it is usually a good idea to ensure that you are getting good performance per watt out of your hardware.
Ideally, your mining hardware would be highly efficient, allowing it to mine Bitcoin with lower energy requirements — though this will need to be balanced with acquisition costs, as often the most efficient hardware is also the most expensive. This means it may take longer to see a return on investment.
In countries with cheap electricity, performance per watt is often less of a concern than acquisition costs and price-performance ratio. In most countries, operating outdated mining hardware is typically cost prohibitive, as energy costs outweigh the income generated by the mining equipment.
However, this may not be the case for those operating in countries with extremely cheap electricity — such as Kuwait and Venezuela — as even older equipment can still be profitable. Similarly, miners with a free energy surplus, such as from wind or solar electric generators, can benefit from the minimal gains offered by still running outdated hardware.
Longevity
The lifetime of mining hardware also plays a critical role in determining how profitable your mining venture will be. It’s always a good idea to do whatever possible to ensure it runs as smoothly as possible.
Since mining equipment tends to run at a full (or almost full) load for extended periods, they also tend to break down and fail more frequently than most electronics — which can seriously damage your profitability. Equipment failure is even more common when purchasing second-hand equipment. Since warranty claims are often challenging, it can often take a long time to receive a warranty replacement.
Price-Performance Ratio
In many cases, one of the major criteria used to select mining hardware is the price-performance ratio — a measure of how much performance a machine outputs per unit price. In the case of cryptocurrency mining hardware, this is commonly expressed as gigahashes per dollar or GH/$.
Under ideal circumstances, the mining hardware would have a high price-performance ratio, ensuring you get a lot of bang for your buck. However, this must also be considered in combination with the acquisition costs and the expected lifetime of the machine — since the absolute most powerful machines are not always the cheapest or the most energy efficient.
Acquisition Costs
Acquisition costs are almost always the biggest barrier to entry for most Bitcoin miners since most top-end mining hardware costs several thousand dollars. This problem is further compounded by the fact that many hardware manufacturers offer discounts for bulk purchases, allowing those with deeper pockets to achieve a better price-performance ratio.
Acquisition costs include all the costs involved in purchasing any mining equipment, including hardware costs, shipping costs, import duties, and any further costs. For example, many ASIC miners do not include a power supply — which can be another considerable expense, since the 1,000W+ power supplies usually required tend to cost several hundred dollars alone.
Ensuring your equipment runs smoothly can also add in additional costs, such as cooling and maintenance expenses. In addition, some miners may want to invest in uninterruptible power supplies to ensure their hardware keeps running — even if the power fails temporarily.
asic mining
Current Generation Hardware
One of the most recent additions to the Bitcoin mining hardware market is the Ebang Ebit E11++, which was released in October 2018. Using a 10nm fabrication process for its processors, the Ebit E11++ is able to achieve one of the highest hash rates on the market at 44TH/s.
In terms of efficiency, the Ebang Ebit E11++ is arguably the best on the market, offering 44TH/s of hash rate while drawing just 1,980W of power, offering 22.2GH/W performance. However, as of writing, the Ebang Ebit E11++ is out of stock until March 31, 2019 — while its price of $2,024 (excluding shipping) may make it prohibitively expensive for those first getting involved with Bitcoin mining.
Another popular choice is the ASICminer 8 Nano, a machine released in October 2018 that offers 44TH/s for $3,900 excluding shipping. The ASICminer 8 Nano draws 2,100W of power, giving it an efficiency of almost 21GH/W — slightly lower than the Ebit E11++ while costing almost double the price. However, unlike the E11++, the 8 Nano is actually in stock and available to purchase.
ASICminer also offers the 8 Nano Pro, a machine launched in mid-2018 that offers 80 TH/s of hash rate for $9,500 (excluding shipping). However, unlike the Ebit E11++ and 8 Nano, the minimum order quantity for the 8 Nano Pro is curiously set at five, meaning you will need to lay out a minimum of $47,500 in order to actually get your hands on one (or five).
While the 8 Nano Pro doesn’t offer the same performance per watt as the Ebit E11+ or AICMiner 8 Nano, it is one of the quieter miners on this list, making it more suitable for a home or office environment. That being said, the ASICminer 8 Nano Pro is easily the most expensive miner per TH on this list — costing a whopping $118.75/TH, compared to the $46/TH offered by the E11++ and $88.64 offered by the 8 Nano.
The latest hardware on this list is the Innosilicon T3 43T, which is currently available for pre-order at $2,279, and estimated to ship in March 2019. Offering 43TH/s of performance at 2,100W, the T3 43T comes in at an efficiency of 20.4GH/W, which is around 10 percent less energy efficient than the Ebit E11++.
The T3 43T also has a minimum order quantity of three units, making the minimum acquisition cost $6837 + shipping for preorders. All in all, the T3 43T is more costly and less efficient than the E11++ but may arrive slightly earlier since Ebang will not ship the E11++ units until at least end March 29, 2019.
Finally, this list would not be complete without including Bitmain’s latest offering, the Antminer S15-28TH/s, which — as its name suggests — offers 28TH/s of hash power while drawing just under 1600W at the wall. The Antminer S15 is one of the only SHA256 miners to use 7nm processors, making it somewhat smaller than some of the other devices on this list.
Like most pieces of top-end Bitcoin mining hardware, the Antminer S15 27TH/s model is currently sold out, with current orders not shipping until mid-February 2019. However, the S15 is offered at a significantly lower price than many of its competitors at just $1020 (excluding shipping), with no minimum quantity restriction. At these rates, the Antminer comes in at just $37.78/TH — though its energy efficiency is a much less impressive 17.5GH/W.

How To Select a Good Mining Pool
Mining pools are platforms that allow miners to pool their resources together to achieve a higher collective hash rate — which, in turn, allows the collective to mine more blocks than they would be able to achieve alone.
Typically, these mining pools will distribute block rewards to contributing miners based on the proportion of the hash rate they supply. If a pool contributing a total of 20 TH/s of hash rate successfully mines the next block, a user responsible for 10 percent of this hash rate will receive 10 percent of the 12.5 BTC reward.
Pools essentially allow smaller miners to compete with large private mining organizations by ensuring that the collective hash rate is high enough to successfully mine blocks on regular basis. Without operating through a mining pool, many miners would be unlikely to discover any blocks at all — due to only contributing a tiny fraction of the overall Bitcoin hash rate.
While it is quite possible to be successful mining without a pool, this typically requires an extremely large mining operation and is usually not recommended — unless you have enough hash rate to mine blocks on a regular basis.
Although it is technically possible to discover blocks mining solo and keep the entire 12.5 BTC reward for yourself, the odds of this actually occurring are practically zero — making pool collaboration practically the only way to compete in 2019 and beyond.
Selecting the best pool for you can be a challenging job since the vast majority of pools are quite similar and offer similar features and comparable fees. Because of this, we have broken down the qualities you should be looking for in a new pool into four categories; reputation, hash rate, pool fees, and usability/features:
Reputation
The reputation of a pool is one of the most important factors in selecting the pool that is best for you. Well-reputed pools will tend to be much larger than newer or less well-established pools since few pools with a poor reputation can stand the test of time.
Well-reputed pools also tend to be more transparent about their operation, many of which provide tools to ensure that each user is getting the correct reward based on the hash rate contributed. By using only pools with a great reputation, you also ensure your hash rate is not being used for nefarious purposes — such as powering a 51 percent attack.
When comparing a list of pools that appear suitable for you, it is a wise move to read their user reviews before making your choice — ensuring you don’t end up mining at a pool that steals your hard-fought earnings.
Hash Rate
When it comes to mining Bitcoin, the probability of discovering the next block is directly related to the amount of hashing power you contribute to the network. Because of this, one of the major features you should be considering when selecting your pool is its total hash rate — which is often closely related to the proportion of new blocks mined by the pool
Since the total hash rate of a pool is directly related to how quickly it discovers new blocks, this means the largest pools tend to discover a relative majority of blocks — leading to more regular rewards. However, the very largest pools also tend the have higher fees but often make up for this with sheer success and additional features.
Sometimes, some of the largest pools have a minimum hash rate requirement ù leaving some of the smaller miners left out of the loop. Although smaller pools typically have more relaxed requirements with reduced performance thresholds, these pools may be only slightly more profitable than mining solo.
Pool Fees
When choosing a suitable pool, typically one of the major considerations is its fees. Typically, most pools will charge a small fee that is deducted from your earnings and is usually around 1-2 percent — but sometimes slightly lower or higher.
There are also pools that offer 0 percent fees. However, these are often much smaller than the major pools and tend to make their money in a different way — such as through monthly subscriptions or donations.
Ideally, you will choose the pool that offers the best balance of fees to other features. Usually, the pool with the absolute lowest fees is not the best choice. Additionally, pools with the lowest fees often have the highest withdrawal minimums — making pool hopping uneconomical for most.
Usability and Features
When first starting out with Bitcoin mining, learning how to set up a pool and navigating through the settings can be a challenge. Because of this, several pools target their services to newer users by offering a simple to navigate user interface and providing detailed learning resources and prompt customer support.
However, for more experienced miners, simple pools don’t tend to offer a variety of features needed to maximize profitability. For example, although many mining pools focus their entire hash rate towards mining a single cryptocurrency, some are large enough to offer additional options — allowing users to mine other SHA256 coins such as Bitcoin Cash (BCH) or Fantom if they choose.
These pools are technically more challenging to use and mostly designed for those familiar with mining, happy to hop from coin to coin mining whichever is most profitable at the time. There are even some exchanges that automatically direct their combined hash rate at the most profitable cryptocurrency — taking the guesswork out of the equation.

Best Mining Pools for 2019
The Bitcoin mining pool industry has a large number of players, but the vast majority of the Bitcoin hash rate is concentrated within just a few pools. Currently, there are dozens of suitable pools to choose from — but we have selected just a few of the best to help get you started on your journey.
Slushpool was the first Bitcoin mining pool released, being launched way back in 2010 under the name “Bitcoin Pooled Mining Server.” Since then, Slushpool has grown into one of the most popular pools around — currently accounting for just under 10 percent of the total Bitcoin hash rate.
Although Slushpool isn’t one of the very largest pools, it does offer a newbie-friendly interface alongside more advanced features for those that need them. The pool has moderately high fees of 2 percent but offers servers in several countries — including the U.S., Europe, China, and Japan — giving it a good balance of fees to features.
BTC.com is another potential candidate for your pool and currently stands as the largest public Bitcoin mining pool. It is responsible for mining around 17 percent of new blocks. Being the largest public mining pool provides users with a sense of security, ensuring blocks are mined regularly and a stable income is made.

BTC.com is owned by Bitmain, a company that manufacturers mining hardware, and charges a 1.5 percent fees — placing it squarely in the middle-tier in terms of fees. Unlike other platforms, BTC.com uses its own payment structure known as FPPS (Full Pay Per Share), which means miners also receive a share of the transaction fees included within mined blocks — making it slightly more profitable than standard payment per share (PPS) pools.
Another great option is Antpool, a mining pool that supports mining services for 10 different cryptocurrencies, including Bitcoin, Litecoin (LTC) and Ethereum (ETH). AntPool frequently trades places with BTC.com as the largest Bitcoin mining pool. However, as of this writing, it occupies the title of the third-largest public mining pool.
What sets Antpool apart from other pools is the ability to choose your own fee system — including PPS, PPS+, and PPLNS. If you choose PPLNS, using Antpool is free but you will not receive any transaction fees from any blocks mined. Antpool also offers regular payouts and has a low minimum payout of just 0.001 BTC, making it suitable for smaller miners.
Last on the list of the best Bitcoin mining pools in 2019 is the Bitcoin.com mining pool. Although this is one of the smaller pools available, the Bitcoin.com pool has some redeeming features that make it worth a look. It offers mining contracts, allowing you to test out Bitcoin mining before investing in mining equipment of your own. According to Bitcoin.com, they are the highest paying Pay Per Share (PPS) pool in the world, offering up to 98 percent block rewards as well as automatic switching between BTC and BCH mining to optimize profitability.

Electricity Costs
While your mining hardware is most important when it comes to how much BTC you can earn when mining, your electricity costs are usually the largest additional expense. With electricity costs often varying dramatically between countries, ensuring you are on the best cost-per-KWh plan available will help to keep costs down when mining.
Most commonly, large mining operations will be set up in countries where electricity costs are the lowest — such as Iceland, India, and Ukraine. Since China has one of the lowest energy costs in the world, it was previously the epicenter of Bitcoin mining. However, since the government began cracking down on cryptocurrencies, it has largely fallen out of favor with miners.
Technically, Venezuela is one of the cheapest countries in the world in terms of electricity, with the government heavily subsidizing these energy costs — while Bitcoin offers an escape from the hyperinflation suffered by the Venezuelan bolivar. Despite this, importing mining hardware into the country is a costly endeavor, making it impractical for many people.
Finding ways to lower your electricity costs is one of the best ways to improve your mining profitability. This can include investing in renewable energy sources such as solar, geothermal, or wind — which can yield increased profitability over the long term.

Bitcoin Hashrate Stabilizing Near 35 Exahash/s After 29 Percent Drop in Mining Difficulty

Bitcoin Hashrate Stabilizing Near 35 Exahash/s After 29 Percent Drop in Mining Difficulty

https://preview.redd.it/v4fhelfwby521.png?width=690&format=png&auto=webp&s=51d0d741515616618e7a201e5376a8d8abf1682d
https://cryptoiq.co/bitcoin-hashrate-stabilizing-near-35-exahash-s-after-29-percent-drop-in-mining-difficulty/
Bitcoin’s hashrate had been rising exponentially from 2009 through mid-2018, increasing through the megahash (M/H), gigahash (G/H), terrahash (T/H), petahash (P/H), and exahash (E/H) ranges. The hashrate first exceeded 60 EH/s in August 2018, and then the exponential increase gave way to stabilization.
In September and October 2018, the hashrate remained stable, averaging above 50 EH/s, simultaneous with the price of Bitcoin being stable near $6,500. Then the price of Bitcoin plummeted starting in mid-November to as low as $3,100 in December. The hashrate of Bitcoin collapsed to 32 EH/s during this market crash, implicitly indicating 20-30 EH/s being forced offline due to a lack of profitability, which represents billions of dollars of equipment.
However, the collapse in hashrate may be coming to an end, at least for now, due to the price of Bitcoin rising back to the $4,000 level combined with a 29 percent decrease in mining difficulty.

https://preview.redd.it/fn5itizzby521.png?width=512&format=png&auto=webp&s=8b65208f22986a6c5409d40255a20e805354d121
As can be seen in the chart, Bitcoin’s hashrate appears to have stabilized in December, breaking the trend of constant decline.
There are two factors that are bringing about stabilization. First off, the price of Bitcoin has stopped decreasing and has risen back to where it was at the beginning of December near $4,000. A stable Bitcoin price is a necessary ingredient for a stable hashrate.
More importantly, the mining difficulty of Bitcoin has dropped from 7.184 trillion to 5.106 trillion, a 29 percent decline, which makes Bitcoin mining 29 percent more profitable per unit of hashrate. As long as price does not continue to fall Bitcoin will find an equilbrium hashrate since difficulty adjusts downwards as miners turn off their rigs. The point at which the difficulty stops adjusting downwards is the equilibrium point, a steady state where the existing hashrate can profitably mine or break even without the loss of further hashrate.
Currently ,Bitcoin’s hash rate is near 36 EH/s, which would yield a 2.6 percent increase in difficulty if the difficulty re-adjustment happened now. This suggests that the equilibrium level for Bitcoin’s hashrate, at least at the current Bitcoin price of $4,000, is right around the current hashrate.
That being said, the price of Bitcoin going up or down can rapidly change the situation. If Bitcoin retraces back towards $3,000, then the hashrate is likely to fall further, and if it rallies strongly then the rigs that were turned off would quickly be switched on again.
The fact that there are 20-30 EH/s of rigs shutoff makes the future a bit gloomy for Bitcoin miners, since increases in Bitcoin’s price will not lead to higher profits for miners until all of those rigs are switched back on.
There used to be a lag effect between Bitcoin’s price rise and the switching on of new rigs, which allowed miners to make bigger profits before difficulty adjusted upwards. Until the hashrate exceeds 60 EH/s, the time it takes to switch on the dormant rigs will be instant, whereas before miners had to wait weeks or months to order rigs and then switch them on. Based on the data, Bitcoin would probably have to be at $7,000 or higher before Bitcoin miners start seeing increased profit margins.
Looking at the broader picture though, it is certainly good news that the Bitcoin mining hashrate has stopped going down since this means Bitcoin will continue to be extremely secure and decentralized. A rapidly dwindling hashrate would make Bitcoin less secure and more centralized, two factors that would threaten Bitcoin’s reputation.

Chinese Miners Have Cartelized Chip Production

I rarely see this talked about if at all. Most ASICS since the time of ASICMINER have been produced in some capacity by TSMC. Ignoring NRE costs, which ironically isn't very high in comparison to chip production, most connected Chinese miners can get chips directly from fabrication.
When Avalon started shipping orders, they also shipped wholesale chips at 10,000 a Batch. Each Avalon chip at the time would generate about 0.4 BTC a month. The procurement cost was about 9 bucks per chip. Given it would cost you about 10-15 bucks to rig a single chip into a miner you were looking at a net ROI of about 20-21 bucks per month with increasing difficulty.
More details can be seen here.
Now it costs about $8-$10 per gigahash retail, which given the difficulty increase, and the fact the impact of NRE costs should be going down (given this expense is less impactful to revenue with the more chips you sell as it's a fixed cost), anyone buying a retail miner is getting fleeced.
I have seen less and less direct chip buys, to the point I'm convinced Bitcoin ASIC production has been cartelized.
The Chinese chip producers will effectively push smaller miners out of the market by over pricing hardware sales to the public, while giving their buddies the "at-cost" price.
The demise of KNC miner is due to miner cartelization.
