Regarding Threads on Bitmain and ASIC Resistance (Mega Thread!)

Guys,
Let’s take a minute to talk about what’s going on. We need to make sure all users are on the same page and the falsifications and assumptions stop.
I'm with you, and I understand that you feel betrayed. However, cleaning up after the constant bickering for those pro-fork and those anti-fork is growing tiresome. It's time we have a civil discussion and talk about facts.

Timeline of events

On 03/31/2018, a user from Ethfans.org posted a video on Telegram of a supposed Ethash ASIC. The video made its way to /Ethermining in a thread. It is important to mention that these values can be modified by changing “get_miner_status.cgi” and “minerStatus.cgi” and that there has been no credible evidence that has popped up in the nine days following the release of the supposed leak. Additionally, the following abnormalities should be noted:
Also on 3/31/2018, a user on Russian site Bits.media noticed that the pre-order for the Bitmain E3 was already up. It was believed to be an April fools joke; needless to say, it wasn’t.
On 04/02/2018, Bitmain launched the E3 and began taking pre-orders for a June delivery. At that time, the price was $800 and promised a hashing power of 180MH/s at 800 watts.
On 04/06/2018, Ethereum core developers decided against hard-forking Ethereum at this time, as they weren't convinced that it would positively impact the community given a hard-fork's disruption and the unknown of how the ASIC worked (specifically if it was programmable). The community became upset over broken promises of ASIC resistance, and this has since spread to a full out finger pointing of who is wrong.
On 04/08/2018, an apparently forged photo showed up showing a higher-hashing ASIC with far less power consumption. This is not only very unlikely, but the link in the photo was gibberish, whereas the E3's link was valid. We're writing that one up as FUD.

The "ASIC Resistance" Argument

At this point, I think that it’s I think it's important that we visit some key points of the Ethereum project. A lot of people have been quoting the whitepaper, calling ETH ASIC-proof and implying that the developers do not care about the problem.
In actuality, Ethereum never promised that it would be ASIC-proof, merely that it would provide an economic incentive to be resistant to the development of an ASIC. I'd like to produce a quote from the Ethereum Wiki, found here.
Ultimately, perfect ASIC resistance is impossible; there are always portions of circuits that are going to be unused by any specific algorithm and that can be trimmed to cut costs in a specialized device. However, what we are looking for is not perfect ASIC resistance but rather economic ASIC resistance.
...
The problem is that measuring an economy in a secure way is a difficult problem. The most obvious metric that the system has access to is mining difficulty, but mining difficulty also goes up with Moore's law and in the short term with ASIC development, and there is no known way to estimate the impact of Moore's law alone and so the currency cannot know if its difficulty increased by 10x due to better hardware, a larger user volume or a combination of both. Other metrics, such as transaction count, are potentially gameable by entities that want the supply to change in a particular direction (generally, holders want a lower supply, miners want a higher supply).
This is solidified by revisiting the whitepaper, specifically the section which identifies how ASICs will be economically stymied:
This model is untested, and there may be difficulties along the way in avoiding certain clever optimizations when using contract execution as a mining algorithm. However, one notably interesting feature of this algorithm is that it allows anyone to "poison the well", by introducing a large number of contracts into the blockchain specifically designed to stymie certain ASICs. The economic incentives exist for ASIC manufacturers to use such a trick to attack each other. Thus, the solution that we are developing is ultimately an adaptive economic human solution rather than purely a technical one.
So with the Ethereum team providing only an economic reason to not develop an ASIC since the beginning, there has been no lie.

Second batch of E3s will not be profitable with Ethereum

As a response to the developers announcing that they are not initiating a hard fork, Bitmain raised the price of the second batch of E3s to $1800. With a PSU ($105) and shipping costs ($225), plus duty fees ($25). That brings each E3 up to $2,155, or $11.97 per MH.
Comparatively, this is like paying $300 per GPU ($1800) plus Mobo/PSU/risers ($355). I have built rigs with similar hashrates for under $1,900 ($10.50 per MH).
If we speculate that Casper is as close as we think (see below), coupled with the rising difficulty, the second batch of E3s are not likely to break-even with Ethereum as a whole. If ETH rises to its ATH, the second batch units may be profitable. Tis the risk of mining.

Current speculation:

  • ASICs are bad!
    • In the Ethereum mining community, ASICs to be viewed as a formidable commodity, when they should rather be viewed as a tool. Tools are never inherently good or bad, but how they are used can be, and some developers intend for the coin to eventually be used with an ASIC. Some coins, such as Sia, were designed to specifically work with an ASIC. > 51% centralization is bad.
  • Bitmain has a better ASIC.
    • Probably. But this is an unknown. Speculation of an ASIC is not a reason to fork the second largest cryptocurrency.
  • Bitmain will be a cause for centralization
    • Everything should be a concern for centralization. Hell, early miners can be a bigger concern. The principals of economies of scale still apply to mining; so those who started out with a lot of GPUs are heavily mining. I've set up warehouses full of GPUs for clients, so if you think some of the guys here are big shots, I promise you there are larger concerns for the current state of centralization.
    • I will also note that yes, we will need to worry about a mass-manufacturer of just ASICs, especially if they are pumping out > 30,000 units per month at the current rate. But the firm that uncovered Bitmain's ASIC, Susquehannah, claims that there are at least three other ASIC manufacturers out there. This puts some silent competition on Bitmain.
  • Ethereum is not as centralized as Bitcoin
    • You'd think that, and the goal of the whitepaper was for Ethereum to be less centralized as bitcoin. It even mentions that "three mining pools indirectly control roughly 50% of processing power in the Bitcoin network." Ethereum is in this state already. Ethermine controls ~28% of the network hashrate, F2pool has ~17%, and SparkPool has ~15%. Arguably, the Ethereum network is in a more sensitive state.
  • Casper is right around the corner.
    • This has been speculation for some time now. Developers confirmed that testnet should be fully operational by August, meaning that we may be able to expect PoS hybrid by DecembeJanuary assuming everything goes as planned.
  • Dev team does not care about miners
    • In the project's current state, miners are a necessity. Remember that seigniorage must be sinigicant enough for miners to continue mining, otherwise, the network would slow and we'd have another Crypto Kitties incident on our hands. Until Ethereum is PoS, you are valid.
  • Dev team wants to get rid of miners
    • Well, yeah. That's what PoS is about. Ethereum will not be Proof of Work forever and that needs to be appreciated.
  • We should fork ourselves into an ASIC-proof currency
    • Do it! Take some initiative and work up a team, I'll be happy to help and support in any way that I can, including pointing my hashing power your way.

Ethereum decision governance

Right now, large decisions are made by the Ethereum core developers. This last decision to not hard-fork was not well received by the community. It feels to be almost an "electoral college" kind of deal, and that's something that has upset a lot of people. Is this the topic that we need to discuss in more detail?

So what is this thread?

For now, this is going to replace our weekly discussion for a few weeks until everything calms down. The sub is in a volatile state and everyone is slinging FUD at everyone else. We need to clean up and calmly discuss our position on the matter at hand. This means:
  • No more fighting about the ASIC in the comments
  • OUTSIDE OF THIS THREAD, please do not shitpost. Meaning, no more strongly worded threads about how you're out of mining completely because of the ASIC, or how the developers screwed you over because ETH was supposed to be ASIC proof, or how people are whining. I'm deleting threads left and right for people who are just using the sub as an outlet to name call on both sides.
  • As always, constructive threads are welcome, but shitposts are to be confined to this thread, please.

We all have different opinions

I am going to remain neutral on this topic. I mine with both GPUs and ASICs, and I've worked with countless numbers of people who do as well. We need to cooperate as a community instead of tearing each other apart over the issue. Let's think before we post and keep comments constructive.
Happy mining!
  • Rob

Starting Mining. What is the best equipment if electricity is not an issue?

So I rent a house that bills are included. I want to start mining and have about 1,000 USD to spend. What rig is reliable and will turn the most profit for the money since I don't pay for electricity or cooling cost, noise is not an issue either.
Could you also recommend any other things a beginner should know?

Cybtc Review: Bitmain Antminer S15-28TH/s

Cybtc Review: Bitmain Antminer S15-28TH/s
Bitmain is a technology company specializing in high-speed, low-power custom chip design and development, successfully designed and produced a variety of ASIC custom chips and integrated systems. Bitmain was founded in 2013. In the same year, it launched the first generation bitcoin mining machine of the ant mining machine series - Antminer S1. After more than five years of development, the antminer series bitcoin mining machine passed S1, S2, S3, S4 Iterations of multiple models of S5, S7 and S9, the latest bitcoin mining models are S15 and T15, which will be sold on November 8, 2018.

The Antminer S15 adopts a new 7nm chip process. The official evaluation of the S15 is durable, energy saving. Emphasizing the characteristics of "high performance, more durable, and more power saving". From the officially announced parameters, the Antminer S15 is built in. Standard and low-power mining modes. The officially announced parameters have a unit-to-power ratio of 57J/T in standard mode, and the unit-to-power ratio of low-power mode has reached 50J/T. Compared to the products in the current market, in terms of Bitcoin miners, this unit power consumption ratio has set a new record.

Antminer S15 official parameters,

https://preview.redd.it/9fgwfaqp6bd21.jpg?width=1015&format=pjpg&auto=webp&s=8239da7bcece1abb80f1fb56708e02fa111a150b

Recently, the Antminer S15 has sent to Cybtc for testing. Please see the third-party independent review by us.

I. Unpacking:

Because the Antminer S15 adopts a new all-in-one and parallel fan design, the packaging box has changed from the previous generations. The previous cuboid has changed into a square-like style. The packaging material is still packaged in an industrial carton, and the box is marked manufacturer information, logistics warehousing logo, mining machine specification model and strip identification code, outer box size: 486*388*265, weight about 8.7kg.

The interior of the two pieces of styrofoam is firmly packed in the box from the upper and lower sides to ensure the safety of the mining machine during transportation. There is also a gap around the pearl foam for easy access.

Take out the styrofoam on one side to see the main body of the mining machine. The mining machine is wrapped by an anti-electrostatic bag. Compared with the box, the mining machine looks very small and only takes up about half of the box space.

The Antminer S15 changed the style of single-tube with double cooling fans as S1-S9 models, and became a dual-fan parallel single-side air intake and adopted the integrated machine design of the mining machine + power supply. The whole machine size is 279*175*221mm, weight 7.13 kg.

https://preview.redd.it/k0xp89yy6bd21.jpg?width=640&format=pjpg&auto=webp&s=5504d958a4cc6fdb1c01783b777e60483ea7ef9a

The Antminer S15 is small and neat, the air inlet side and the mining machine interface side are on the same side, the fan is removed from the air outlet side, and a honeycomb-shaped baffle is used.

https://preview.redd.it/ex187jf27bd21.jpg?width=640&format=pjpg&auto=webp&s=e8210c514e186dae075d9b986f7682a49141aa6a

The advantage of the all-in-one design is that the wire connection is reduced. The appearance of the mining machine is more compact, and the use and operation and maintenance are more convenient. The connection between the Antminer S15 mining machine and the power supply uses a clip-connected design, and the controller and the power board are still connected by flat signal cable.

https://preview.redd.it/85cz4u4c7bd21.jpg?width=640&format=pjpg&auto=webp&s=ab87c2f4c2943f0e9eb3dbbe2576f9d043add399

The nameplate of the mining machine body is marked with the model number, hash rate, and identification bar code. If the bottom part can increase the anti-slip mat, it is better to strengthen the stability of the mining machine when it is placed horizontally. The mining machine supports the erect and horizontal two ways. On the rack, the miner can choose the placement method according to the size of the mine rack.

II. Antminer S15 installation:

The design of the Antminer S15 all-in-one machine reduces the link of the power line of the plugging and unloading machine. As long as it is placed in the rack, plug in the power cable and the network cable to complete the hardware installation.

Find the mine IP address. Antminer S15 mining machine is automatically assigned IP mode, you can enter the local router to view the IP address named "antMiner".

Or use the ant official mining machine management software BitmainMinerTool to scan the IP address of the current mining machine. You can also use the management software to set the mining pool address and worker name, update the firmware, etc. When the number of mining machines is large, you can also use the mining machine. IP report button to find the IP address of the mining machine.

To view the real-time status of a single mining machine, you need to enter the mining machine control page. First, enter the mining machine IP into the control page home page, and then enter the default user name and password (the default is root) to enter the mining machine control page.

The new mining machine needs to modify the name of the mining pool and miners, click on the “Miner Configuration” page to modify the main mining pool address and worker name, and modify the two alternate mining pool addresses and miners' names as needed. Antminer S15 has built-in standard and low-power mining modes, so you can easily select any mode mining on this page according to your needs. After each setting is completed, click “Save&Apply” to save the settings and apply.

After saving, the miner will restart the mining procedure. After about a few minutes of normal operation of the mining machine, you can enter the mining operation interface “Miner Status” to check the operation of the mining machine, including running time, hash rate, Chip status, operating frequency, PCB board and chip temperature, fan speed and other parameters information.

III. Review:

The Antminer S15 has standard mining mode and low power consumption mode. Therefore, we tested the two modes for 24 hours respectively. The test environment temperature is about 17 degrees, and the noise value is around 36 decibels.

https://preview.redd.it/2wzornwmabd21.jpg?width=640&format=pjpg&auto=webp&s=62e6e57755d70d526eeda4066a31b042473871a8

After the mining machine is turned on, the fan runs at full speed, the power consumption of the boot is about 25W and further increases slowly, and the noise level is up to 81.2 dB.

Standard mode test

Power consumption: The miner's chip is fully operational, and the control page power is 28T. The measured power consumption of the miner is 1610-1620W, which is in line with the officially announced 1596W ±7% level.

Noise: Due to the low ambient temperature, the number of fan rotations is basically stable at around 3120 rpm. The noise value of the operating environment is measured to be 76.5 decibels. The distance of the mine is 27.7 meters, and the noise level is properly controlled.

Temperature: Antminer S15 has a total of four mining boards. There are four temperature-sensing modules distributed on each calculation board. The chip temperature is at least 44 degrees and the highest is 78 degrees. Thanks to the Exposed Die package, the outlet temperature is about 42 degrees. The power outlet temperature is about 28 degrees.

https://preview.redd.it/h71plzf0bbd21.jpg?width=641&format=pjpg&auto=webp&s=588728e6a87b510d5cc65eb41a1ffe80d6435f17

Because the Antminer S15 adopts the one-piece design, We also test the contact temperature of the power supply and the mining machine's power board. It can be clearly seen that the temperature values ​​of each point are different.

https://preview.redd.it/4ghcl4i3bbd21.jpg?width=990&format=pjpg&auto=webp&s=a344917e4a3b529aef58127f5e5c8fdaa61c62fa

Hash rate: After 24 hours test in the btc.com mining pool, the average hash rate of the Antminer S15 in 24 hours was 28.56 TH/s. Thus calculate the unit energy efficiency ratio = 1620W / 28.56 ≈ 56.72W / T, and the official published data 57 J / T consistent.

Low power mode test

Power consumption: After checking the option behind “Low Power Mode” on the Antminer S15 Pool Settings page and saving the application, the miner can run in low power mode. After the power of the mining machine control page reaches 17T, the measured power consumption is up to 836.6W, and the running data meets the official data of 775W ±7% - 900W ±7%.

Noise: As the power and power consumption are reduced, the fan speed is basically stable at around 2400 rpm, the measured operating environment noise value is 77 decibels, and the distance measured by the mining machine is about 66 decibels at a distance of 2 meters. The noise level and the standard mode. At the same level.

Temperature: The four mining board chips have a minimum temperature of 25 degrees and a maximum of 62 degrees. The outlet temperature is about 30 degrees, which is slightly lower than the standard mode. The temperature of the power outlet is about 20 degrees.

https://preview.redd.it/r4f2ww96cbd21.jpg?width=641&format=pjpg&auto=webp&s=ae3051c74634ac9d98373d71e8fee3f542d455c5

Contact point temperature value between the power supply and mining machine mining board.
https://preview.redd.it/fskmubi8cbd21.jpg?width=990&format=pjpg&auto=webp&s=a1616d21af2b87bc0996f1ce388b3ab9983d33dd

Hash rate: After 24 hours of testing in the btc.com mine, the average 24-hour power was measured at 17.5TH/S. Thus calculate the unit energy efficiency ratio = 836.6W / 17.5 ≈ 47.8W / T, lower than the official published data 50 J / T.

IV. Summary:

Two built-in mining modes. The power consumption per unit of power in low-power mode is lower than 50W/T, which is better. The lower the power consumption ratio, the lower the price of the shutdown.
One machine design reduces the wire, beautiful and convenient.
Exposed Die package improves heat dissipation, increasing the number of chips per unit volume and reducing heat sinks, reducing overall weight.
The new AWP8 power supply is used, easy to assemble and disassemble.
The machine noise is lower and the temperature is lower than other mining machines.
The calculation power of the whole machine is stable and fluctuating.

Finally, exposed power connectors may cause problems if touch the iron on the shelf. Maybe it can have improvement.

The Antminer series mining machine has evolved from S1 to S15, and the computing power has evolved from S180's 180G/360W to S15's 28000G/1600W. This is not just a digital evolution, but also the ups and downs of the Bitcoin industry. The mining machine is upgrading. Bitcoin is advancing, leaving many stories in the chain, the currency circle and the mining ring than the ten-year journey of holding the currency. In the two-year life cycle of S9, S9's bitcoin mining machine market share is far ahead, and currently in the market background of the rising bitcoin computing power, the depressed bear market and more new mining machines, Whether the ant S15 can create a new benchmark for the bitcoin mining machine, time will give us the answer.

I am thinking of using a bitcoin miner to heat my house this winter, thoughts?

My calculations that a simple Antminer S5 (1100GH) will replace my gas furnace heat output at roughly a 1:1 price equation of electricity use = gas savings. It basically means free electricity for my miner making ROI significantly easier.
Thoughts on this? Has anyone done it? I have never entered the mining space before and I am looking for a small entry unit similar to the S5 probably sometime late this summer, if anyone has any experience that would be great to know.
My plan is to put a air filter on the front of it, and hook up the exhaust through some tubing to my central air system and have it constantly pumping it's exhaust heat through my house. I expect a single S5 to reduce the heat required by about 20%. I can envision a product where Bitcoin hot water heaters or bitcoin central heating in cold climates significantly reduce the impact of the marginal cost of maintaining these systems by reducing the real costs of electricity to a point where industrial farms can't compete because you are replacing an actual NEED.
Thanks

Plz Help. Have I found a Discrepancy in Slush Pool?

I may have found a bad discrepancy in Slushpool's reporting... Can you guys cross-check it for me? I'm not happy to say this, and rather than accuse anyone, I'd just like to get some second opinions. If I'm wrong, I ask redditers to politely explain why this discrepancy appears to be happening. After all, maybe it's my math, or logic, or facts missing, etc... But if there is a discrepancy, it could affect major things like payouts, theoretically... and I mean in a major way... retroactive for years.
My concern starts with the average speed per worker of the bitcoin mining pool, on Slushpool.
As I write (12/26/17 Pacific time, around 11pm), Slushpool currently says it is running at 1.587 Eh/s. https://slushpool.com/dashboard/?c=btc
The website also says there are 62810 workers in the pool. I want to calculate the speed per worker. Speed per worker should be expressed in Th/s, so to reduce it to common terms, we need to convert the pool's global Eh/s to Th/s... which means to multiply the Eh/s by 10002... one thousand, squared.
The speed of Slushpool was 1.587 Eh/s, so we set it up like this: 1.587 * 1000 * 1000 = 1587000 Th/s. †
Now to get from Slush Pool's total Th/s to Slush Pool's average Th/s per worker, divide total by number of workers...
(1587000 th/s) / (62810 workers) = 25.26 Th/s per worker.
So I got the number I was looking for... excellent. You might say "Okay, interesting, so the average worker is mining at 25.26 Th/s. NP. Cool."... But what you SHOULD be doing here is asking HOW ON EARTH ANY WORKER IS MINING AT 25.26 TH/S, and even moreso how THE AVERAGE worker mining on Slush Pool is mining at that speed. The fastest miner on the market is the s9, and it mines at 14 Th/s. So how is the average miner on Slush Pool more so much faster than the very best miner on the market, today? The S9, The BEST MINER on the MARKET, today, is only 56% the speed of the AVERAGE miner on Slush pool.
Now, maybe somebody built a specialized frankenminer in a laboratory... maybe someone uncovreed a secret cache of Spondoolies SP50 miners... which was designed to mine at a whopping 110th/s, for example... but Spondoolies went bankrupt in 2016, and production was halted. Even before then, they didn't make too many sp50's, and they were restricted to special clients.
So... assuming it isn't legacy Spondoolies sp50's doing this mystery hashing, how else can we explain the high h/s on Slush Pool? Maybe someone got really good at overclocking... maybe they cooled the hell out of their miners, so they can run at super fast speeds. Would that really be enough to yield 25.26 Th/s? Is that credible? Is it possible or plausible? ... Even if some miners are achieving that incredibly blazing speed, would the AVERAGE miner be achieving it?
Don't forget about how the AVERAGE includes all these micro miners, as well... misfits like the u3, gridseed orb, blade miner, s1-s5, running in a dorm rooms, etc. There are hobby miners who would pull the average h/s (per miner) on Slush Pool down alot.
So, how is it possible that the pool is running at this speed? Better asked... IS it possible, and if so, how? And if it's not possible, then what are we looking at?
If the pool operator is overstating the total hashing power of the mining pool, then are payouts being reduced according to a false ratio, where the divisor in the ratio is artificially large? The payouts are based on that... they depend on it. So are the payouts on Slush Pool being artificially shrunken? If the total Eh/s of the pool is really much lower than what they say, then I'd have to suspect that it is. But I am absolutely NOT saying for certain that this is what's happening. It's what my suspicious anxiety closet suggests could be happening... but I really don't know. That's why I'm asking you guys to help sort this all out, and explain to me whether these concerns are misguided or not. I'm asking a question, here... not throwing accusations. Frankly I think it is more likely that I've made an error of some kind, either miscalculating or possibly unaware of some vital detail, than that the net's oldest and most respected mining pool is doing something like this. It is very likely there's a good explanation for the apparent discrepancy, but I do not know what it is... so again, I'm asking you, reddit, if you can evaluate this reasoning and comb it for flaws, math errors, weak factual assumptions, and/or whatever else might explain what I'm seeing, or if you can confirm the math and logic framed in the questions I've asked.

LEASING CONTRACTS
I have started to offer leasing packages for use in approved Data Centre/Co-locations. This can be beneficial for many reasons:
-Less upfront capital required, allowing more to be spent on additional mining hardware which can offset much or all of the cost of the lease
-Limits risk and cost of equipment failure, and associated down time due to failures
-Saves shipping costs for heavy PSU's to and from hosting location for duration of your contract
-No equipment depreciation
-Helps eliminate ownership problems associated with Group Buys, when more than 1 member shares purchase price of PSU to host together
-All maintenance, replacement, shipping, setup, and lost revenue from down-time due to PSU failure is my responsibility
Please contact me for details.
Shipping
Shipping will be calculated individually, to make sure you are getting the best rate. All prices are in USD. I am willing to accept escrow through OGNasty, and can also do Paypal but buyer will be responsible for covering costs of either services (4% added to paypal, OG charges 1% for escrow).
Each package of PSU, breakout board & 10x PCI cables is approximately 16 lbs.
The BTC address for all non-escrow breakout board orders is here: 1GWQYCv22cAikgTgT1zFuAmsJ9fFqq9TXf I will not PM you asking for payments to any other address, so beware of F1nksy, Fink5y, or whatever scammy names might pop up.
Original Post:
Hi everyone,
I am the official North American distributor of Break-out boards for the IBM 2880W Bladecenter H PSU's, which are 80+ platinum rated (94%+ efficient) Edit: UN-VERIFIED AT THIS POINT and have provision for 22x PCI-E cables. Unlike other server boards, these don't rely on screw-down terminals and bare wires which can get loose and spark causing fire hazards, and limit the exposure of live contacts to surfaces above and below the PSU. Instead these use a double-sided PCI 6 pin cable, which only cost about $0.10 more than the standard PCI-6 to bare wire versions. Also, unlike the DPS-2000BB -which is the next largest server PSU available for miners- these have fans already built-in, so don't need extra work to set up up and deploy.
The PSU's themselves are available on e-bay and elsewhere (I sell them as well), and the boards will be priced at US $70 $65 each (better pricing for bulk purchase, volume structure will be the same as J4bberwock's). Each PSU can handle 2x Antminer S7's, 3x SP20's, 5 Antminer S5's, or 8 Antminer S3's. You won't find better value for power, and there are very few ATX-based PSU's that provide 80+ platinum efficiency (and none for under $200 for even 700-800 watts). Edit: UN-VERIFIED AT THIS POINT Lastly, unlike ATX-based PSU's, these can be run at (and I have found even over) their rated power, as they were designed that way for server use. They do, however, require 240V input. Also, running these over at over 90% load will give you slightly decreased efficiency, and could affect their reliability.
I have personally taken 3x SP20's to settings around 960 watts (at ports, not at wall) each for approximately 2 weeks, and the PSU drew 13.41 amps (@ 235 volts - 3150 watts @ wall). So at absolute full load (or possibly over), these will still hold over 90% efficiency. Very impressive, and I will be testing different fans to reduce sound for home mining (fans on these PSU's are slightly louder & higher pitched than SP20 fans). Sloopy informed me that he ran 11x Antminer S3's on a PSU for a while (over 3,300W DC!), but that is certainly not recommended, and will eventually cause the PSU to fail. It is simply a testament to how tough these PSU's truly are, and that spikes over their rated output shouldn't affect performance.
Here are some pictures:
Feel free to contact the developer of these boards if you have any concerns, he will verify that I am authorized to sell these. https://bitcointalk.org/index.php?action=profile;u=206446

Is anyone buying mining hardware anymore?

Been mining for about 2 years now and I've been using the S5 since its release with positive results. Even with free electricity the difficulty increase is grinding my payouts to a halt and I've been considering another miner but nothing seems to have the hash power to offset the difficulty for long. Currently the S4 looks good as I've seen prices as low as $495. Is anyone considering buying any new hardware or is the consensus buying bitcoin outright now that the difficulty is so high? Thanks for any insight!

Actual, real crypto investments?

We all know, or at least we SHOULD know, that cryptocurrencies are not an investment. Right?
The trouble is, ever since that famous $7 million bitcoin pizza, the crypto world seems to be divided between the early arrival millionaires, the wannabes, and the predators out to scam them.
And there has been a very, very long list of scammers, hasn't there? Many of the names are well known, especially the ones in jail, or heading there.
Trouble is, like a shark in a shoal of fish, they scared many away, especially the get-rich-quick crowd. Its not easy to watch your money evaporate, and the effect on the community as a whole is crippling, as the departing hordes do more damage to the cryptoconomy than the predators ever did.
Over on /asicgroupbuy, we've had our share of disasters. We had one of our own lose over $7k of our money, and then disappear, in shame or guilt. It doesn't really matter which. We were into GAW's scam, though we got out with a profit. We were gobbled up by Moolah, and most recently by Chris's LTCgear scam. We've reached a point where people are saying there's nothing left to invest in.
While cryptos aren't an investment, there are investments in the cryptosphere. Mining being an obvious one... but as we all know, the days of the small miner are well and truly over. The rewards are simply not enough to cover capital and operating costs. Don't believe me? Try it yourself, but be prepared to lose most or all of what you put in. And of course so-called 'cloud' mining is for the most part a massive con. Sure, they may pay out short term... After all, I paid for my ex-GAW Gridseeds thanks to profits from the Cointellect scam before they soured. But the numbers just don't stack up when you look hard.
And yet, we all know there IS money being made in mining. Mostly by those huge, anonymous chinese mines we've all seen pictures and videos of. Noisy, hot, dank hellholes hidden in the jungle with thousands of screaming ASICs and a couple of guys running around 24/7 keeping them going and sleeping on the floor.
But this kind of thing costs millions, and is way out of our league.

Or is it?

Yesterday, I was in town, picking up a batch of (physical, non-crypto) coins someone brought back from Sydney for me. And it was a glorious day, perfect for a leisurely stroll.
I had been looking at the Bitcoin Group's IPO, after seeing that our new Prime Minister has kicked it off with an OnMarket Bookbuilds launch. I even linked the referral on my Facebook page, not that I expect anyone to ever use it. I read the Prospectus (Note: Specifically NOT available to US citizens) and was thinking of investing. So I thought "Why not drop by their office and pick up a paper copy? Makes the form easier to fill out if I decide to buy shares."
Well, I gotta say I was impressed. I met much of the team, had a long chat with Sam, their CEO, and had all my hard questions answered. Ended up borrowing their WiFi to transfer a couple grand over for a small stake, and will likely increase it before the offer closes.
In a nutshell, they're going to ramp up their existing mines in China and Iceland to around 13% of the total BTC hashrate. The Chinese mines are located in remote areas, adjacent to hydro power stations... apparently these stations can't sell their electricity onto the grid, so they've done really good deals to supply cheap power. Current ASICs are Antminer S5's, with a mix of S5's and the coming S7's making up the 50,000+ miners to be installed. They should be generating around $35 million a year, and although they won't be paying dividends, by reinvesting profits their market cap should increase nicely. At least that's the plan.
This is a real company, very open and inviting. They even host the Melbourne Bitcoin Meetups and have a museum and facilities for public use. Here's a pic of Martin in the museum room which has examples of every miner ever built... an impressive collection of mostly black boxes. ;)

Note that this is not an invitation to invest in this particular company!

Apart from the fact that that would be illegal in the US (although there ARE ways for americans to buy in via proxies), this post is not about one company. Rather it is about the fact that real-world opportunities DO exist, and we shouldn't let the 'Wolves and Weasels' (to borrow GoodShibe's description of them) destroy our faith in the crypto world.

Nor is this about BTC.

While Bitcoin Mining is the current most profitable way to mine, that won't necessarily hold true indefinitely. We spoke at length about next year's halving, and although our opinion on the likely outcome differed, they do have plans in place either way. Sam told me he holds significant amounts of altcoins, including Doge, and is not averse to them. While the focus is now purely on BTC, that isn't necessarily graven in stone.

Stay Active, and Keep Your Eye On The Ball!

There are most definitely legitimate opportunities in the cryptosphere. Whether its Dogecoin or Bitcoin or something else. Whether its a public float of a mining company, a new exchange, or some other business, some very smart people are doing a lot of hard work creating value out there.
But you'll never hear about it if you don't listen. Just like we all found out about that pizza long after it was too late to get aboard, if you don't pay attention, you will be sitting on the sidelines wishing you had known about the next big thing. Sure, /dogecoin isn't what it used to be. Neither are any of the other crypto subs. So what? That just makes them easier to keep an eye on, doesn't it? Stay subscribed. Look in regularly. And read (and maybe even upvote and comment in occasionally) all those posts that aren't about the good old days, or silly dog/pinapple pics.
Maybe that way, THESE will become 'the good old days'. Think about that. :)

Wanting to get into Bitcoin

I'm wanting to get into bitcoin, especially mining. I was looking at the AntMiner S5. I was wanting to know, is it really worth it? Can I really make a few hundred per year just by buying this box and plugging it in? Also, I know I can (somehow) spend the bitcoin, but how could I also convert some to USD to spend either as paypal or cash? Thanks and sorry if it doesn't make much sense, I'm really new to bitcoin but I want to try getting into it.

Is mining really this simple?

Hello, forgive me for asking a stupid question. I come from a very poor family, I am used to working hard to make any money, and am skeptical of anything that sounds like easy money, this whole Bitcoin Mining thing seems too good to be true. I want to air my assumptions.
So; I get a Bitcoin wallet, buy an AntMiner S5/7 and power supply, hook it up to internet and configure it, join Slush's mining pool, and just leave the miner running in my basement. Each month I will earn ~0.186 BTC which I can convert into fiat money (~$79)?
Did I miss anything? My electricity is $0.07/kWh, so I am looking to pocket ~$48 a month? Really? Someone tell me I am wrong, cause this sounds insane...
Thank you,
