Another update on my solar powered farm and bitcoin mining in the desert

Tl;Dr - Just skip to the bottom where I lay out my solabattery requirements for mining and my solabattery requirements for vertical farming. Oh...and costs and earnings.
Well, Summer is here and we have had some extremely hot weeks. This has given us a chance to test our greenhouses at temperatures of 126F/52C. We are still up and running quite well. Our energy requirements have gone up quite a bit. But the electricity we are consuming is right in line with our estimates. We do not feel that the temperatures will be any higher than the numbers we have seen so far. Unless Global Warming is for real...because now that I think about it, we did blow through our all-time-high in temperatures...and this was the last day of Spring, if I recall.
We are ordering all of our equipment directly from China. Our 40' greenhouses are extremely cheap to build in China. We are building them for about 40% of what companies like Freight Farms and Bright-Agro-Tech are selling their systems for. Our system is at least 90% as good as their systems. But we do have many bugs, it seems when we first receive them from China. Perhaps my main complaint. They can be a bit finicky. I would not want to sell these as the customer service would consume me.
Our most simple greenhouse uses between 250 and 450 kwh per day. I am in San Diego. Our residential rates from SDG&E are $0.43 per kwh. That is crazy high, for the record. This would cost between about $105 and $190 per DAY. Between about $3,000 and $5,500 per month. Most people in the US pay about $0.11 per kwh. This would equate to a monthly bill of $750 and $1350 per month. The Arizona desert pays that rate, for example.
Next, these greenhouses grow about 4,000 heads of lettuce per month. Wholesale price for this lettuce is $1. We sell direct to the end user. We charge $1.50. But at wholesale prices, this generates $4,000 per month in revenue. Labor is 10 hours per greenhouse. We pay $20 per hour. When you add all the California bullshit taxes and fees for employees this puts us at about $30 per hour. We also have insurance and Workers Comp. This is about $40 per month for each greenhouse.
Ok, now for the solar and battery requirements. We use 150 panels of 300 watt panels. I know...this is a lot. It takes a lot of space. You need a lot of cheap land. We spend about $0.45 per watt for solar panels from China. Our lettuce greenhouses run for 8 hours per day with lights. The other 16 hours we go "dark" and do not use much energy (just pumps, air conditioning and a few devices). We run the lights and everything during the peak sun hours. This allows us to not purchase as many batteries because we are turning the sun directly into the farming and lighting. Then, when the sun starts to wane, we turn most systems off and just remain in a well-insulated state. The battery requirements are still large, however. We currently use 50 lead acid batteries for each greenhouse. Each battery is 24V and 200 amp hours. Each battery costs us $180 from China.
Ok, how does this all tie into bitcoin and bitcoin mining? Here's the answer. Each Antminer S9 uses about 1400 watts when it is placed in the environment of our lettuce greenhouse. We place between one and four miners in each greenhouse. We need about 6,000 watts in solar panels to charge up the batteries and simultaneously run one S9 for 24 hours straight. We need 15 of the 24V/200 amp hour batteries for each miner. Cost for panels is $3,000. Batteries are $2750. The miner, when you buy from Bitmain is $1225 delivered to your door in the US. I have over-clocked the miners as high as I am comfy with. I am generating 0.007 btc per miner per day right now. That is about $18 per day at today's rate.
So here is how it all breaks down for the vertical farm: cost for one lettuce farm that is 100% off grid is about $90k. This includes EVERYTHING... solar, batteries, control systems, installation and framing for the solar, greenhouse, all equipment, air conditioners a water cooler...everything. Monthly labor, insurance, nutrients and supplies is $1500. Shipping of the lettuce is about $400. Total net profit is about $2100 per month. And $25,000 per year.
Mining...ok...this is the wobbly one to predict. Just remember this and it'll make it all easier to accept these numbers: bitcoin is probably headed to $10,000 within 3 years. If you don't believe that then much of this will just be comical to you (if it isn't already). One miner will cost (miner + solar panels + batteries + power control systems + cooling equipment and the solabatteries to support it) = $8000. The solar and battery system costs a total of $6800. The miner is $1200. Once you have purchased the solar and batteries, you own them forever. They can be used to mine for 25 years for solar and at least 6 years with the lead acid batteries. You can amortize these costs. If bitcoin drops to $0 then you can instantly switch your solar and batteries to your farm. This is how I backstop my potential losses.
Now, here is the magical way we have figured out how to avoid the "decay" that is built into the miners: we run them for 4 to 8 weeks then we sell them on the open market at a premium over cost. When you purchase large numbers from Bitmain, they will offer you a discounted price. The miners seem to always go up in value in between releases fom Bitmain. After 6 to 9 months of reselling at this pace, you will make all of your initial investment back in the miners. You will also stay current with the miners. So, one miner will generate about 2 btc per year (when you stay ahead of decay). That is $5,000 per year at today's rate. If bitcoin follows the trend (and you believe) then I expect that you will generate $6500 or more within one year from mining today. This means the system will completely pay for itself (including solar and batteries) in about one year. Oh...and then after a year, you own a brand new miner (cuz you have been constantly reselling them to stay current and slightly profit). Oh...and you how have 6kw of solar AND batteries...just keep mining til bitcoin is outlawed. You are now in a unique position...your mining rig costs you $0 from this point forward.
I have calculated the amount of profit you can make if you build your own solabattery array and point this array to different businesses. One business is a modern, vertical farm which is good for the environment and makes healthier food. The other is a bitcoin mining operation. Both businesses have energy as their single largest cost of doing business. I like the idea of having two businesses that I can just point an energy source towards and they start making money. Isn't that kinda cool to think about? Farming generates a net profit of $0.22 per kwh from a solabattery system. Bitcoin mining generates $0.51 per kwh for the exact same system. Think about that for a minute.
Also, what the fuck? If bitcoin actually does take off, imagine how it will pollute the world with miners in places with shitty but cheap fossil fuel. Shouldn't we be mining on renewable energy since...let's be honest, bitcoin shouldn't really exist? It only exists because people lie a bunch. It seems like protecting ourselves from our despicable selves shouldn't turn the world into a toilet that may become uninhabitable.
I just wanted to share everything with this community. If it weren't for this community, I would have been nervous about trying this crazy idea. What I mean by this is that I appreciate the handful of people here who have a lot of bitcoin and just handed them over to me so that I could test this TOTALLY insane and HIGHLY SPECULATIVE business model. I told you (those who lost their btc to me) that I will make it up to you. For the couple of you who didn't threaten to kill me, I will return your btc when my profits from mining hit 4,000 btc, unless the price is under $3100 per btc...seems fair...you did lose...and it was a fair bet.
I hope for several things from this post. (1) The nice people who are here hopefully will take this info and appreciate what went into getting these numbers. (2) Someone will read this, run the numbers themselves and decide to do the exact same thing. (3) Someone in an area with good sun, year round, will set up a mining operation based on my model. (4) Someone will bet me publicly again that I am lying. (5) Someone interesting will buy the land next to mine and compete head-to-head with me...I seem to perform better under competition.
To;Dr - To take a miner off grid, in a sunny place, will cost $8,000 (including the miner). You'll break even in a year if you follow my plan (and if fate complies as well). One 40' greenhouse that is off grid costs me $90k. Least amount of net profit per greenhouse is $25,000 per year. Average net profit is $36,000per year, typically from blending lettuce and other crops such as basil.
Farming generates a net profit of $0.22 per kwh from a solabattery system. Bitcoin mining generates $0.51 per kwh for the exact same system. Think about that for a minute. We sell energy back to the grid for about $0.05. Does anyone look at this the way I am looking at it?...I am just curious.
Anybody have any questions?

On the Security Economics of Public Blockchains: Why using the Ethereum public chain for STO contracts is not a good idea

by Hendrik C

We coin the term “security economics” to mean the system of economic incentives designed to guarantee the security required for a public chain to operate. For example, with PoW (proof of work), honest miners are incentivized to contribute compute power for mining reward. The higher aggregate hash rate of a network, the more difficult it will be to perform a 51% attack. We will introduce a new framework to analyze this relationship, and study the limiting cases where the current security economic relationship might breakdown.
In a given period T, the blockchain network will release n coins according to its predetermined mining schedule. For example, bitcoin currently reward 12.5 coins per block. Its mining difficulty is adaptively set so it produces 144 blocks per day, with a very small margin of error. Whether total network hashpower is 50 ExH/s or 5 ExH/s, total reward per day is always 1800 bitcoins. Only difference is that the expected reward per hash diminishes when total network hash increases. But hashpower cost money, 50 ExH/s will cost 10 times as much as 5 ExH/s, assuming they’re running on the same kind of hardware. The economic equilibrium is arrived when reward per day (RPD) = cost per day (CPD).
We further breakdown CPD to its components: sunk cost (e.g. cost of the miner) and operating cost per day (OCPD). We make the following postulates about the mining process and miner’s behavior.
1, When price of a coin goes up, temporarily RPD > CPD, new hash power will be introduced as it will be profitable.
2, When price of a coin goes down, but RPD > OCPD, then nothing will happen.
3, When price of a coin goes down so much, that RPD < OCPD, some miners will stop mining, total network hash will fall, until RPD > OCPD again.
4, Mining hardware have a useful life of approximately 2 years, miners would only deploy new hardware if they can cover cost within 1 year of mining.
Assuming the above behavior of miners, in the equilibrium state, the total hash power (per second) of a network is bounded above by the market value of expected reward (per second). To stage a 51% attack on the network, the adversary will need to match all of the existing hashpower on the network. The required investment is approximately equal to the market value of minable coins in 1 year. Take bitcoin for example, a total of 52560 BTC are released to miners a year, which equate to about $189m, assuming $3600 / BTC. The total hashpower of the bitcoin network is about 42 ExH/s, which equates to about 3 million Antminer S9’s. This is what it takes to stage a 51% attack, the cost of staging such an attack is a good measure of how safe a network is.
Would anyone do it? Perhaps not, which is the ingenuity of Satoshi Nakamoto. Assume you did invest $189m, and compromised the bitcoin network. What returns will you get? Sure, you double spend bitcoins, but bitcoins will be worthless when people find out its security is being compromised. The delicate game theoretic equilibrium, which we shall call the Nakamoto equilibrium, is just as important as all the cryptographic wizardry in keeping a blockchain safe.
The Nakamoto equilibrium design has a number of drawbacks, although none of them were of interest for Nakamoto to consider, they do not apply to bitcoin.
1, Nakamoto equilibrium only guarantees the security of the public chain itself, and not the smart contract tokens which runs on it.
2, Out of all the blockchains that use the same hash algorithm, only the one with the most honest hashpower is safe.
We will focus the remainder of this paper elaborating point number 1, and leave 2 to another article.
The utility tokens created in the ICO hype, were predominately ERC 20 contracts executed on the ethereum network. Despite of their huge speculative value, these tokens do not have much intrinsic value right now. They simply represent the access right to a particular utility, which will be built (if ever) far into the future. The aggregate market value of all ERC 20 tokens, have never exceeded that of ethereum. Hence, the hashpower required to guarantee the safety of ethereum is automatically extended to the ERC 20 tokens running on the network.
We now consider a scenario with securities tokens produced from STO’s. A security token represent a share of a securitized asset. These could be company stocks, bonds, buildings, infrastructure etc, indeed everything in the world could be securitized and tokenized on a blockchain. The fundamental difference between securities token and utility token is that securities token have an intrinsic value attached to it. The intrinsic value of a securitized asset could be several times the market cap of the public chain it’s running on.
For example, as of Feb 2019, ethereum have a market share of about $8 - $10 billion dollars. About 7 million ETH is minable a year (before the Constantinople fork), the total value at current market price of $120/ETH is about $840 million. The total network hashpower is 140 TH/s. A Bitmain E3 miner has an advertised performance of 180 MH/s, so total network hashpower is equivalent to about 777777 E3 miners, which would cost roughly $800 million (though the exact cost could be quite volatile). This is how much one would have to invest to stage a 51% attack on ethereum network. If the network consists of only ETH and utility tokens, whose value would plummet if such an attack were to be successful, nobody is incentivized to do so. But (imagine sometime in the future), if the ethereum network has securities token contracts, whose underlying asset worth a total of a trillion dollars, then carrying out such an attack would seem quite profitable.
A new security economic model is clearly required for any public chain to run securities token. The biggest problem with ethereum, is that miners are not incentivized to contribute hashpower, as a function of total market cap of tokens running on ethereum. This is not a problem in the era of utility tokens, when they are worth significantly less than the main ethereum network. In the era of securities tokens however, this will become a significant risk, as securities tokens can easily worth several folds more than the public chain itself. We need to figure out a new economic model, where the public chain’s hashpower is a direct function of total token value running on the public chain.

Beginners profitability desperate questions

sorry for my english
Hello, I'm crypto enthusiast, already have been mining with s9 for 2 months. I did some basic research, calculated my future income, sadly it's not that much - with 20% difficulty, antminer s9 won't cover electicity bills in July and will never pay off itself. So I have 2 questions, why antminer is still popular, it's not gonna cover it's cost, am I missing something? And second one, not a question, more like asking for advice or reasoning - isn't it better to sell it (people ready to buy it for 2k usd) and buy 0,2 bitcoin, since antminer would reach 0,08 btc in 180 days and then just stops??? Thanks you in advance.

Napkin Math: Total Global Average Cost to Mine a bitcoin

I've made a few assumptions below to try to come to a very generalized understanding of what a bitcoin costs to mine on average, globally, post "halvening." I'm not trying to be too precise and would be happy if I was within 10%-15% of what may actually be true. I tried to stay somewhat conservative (I think) in the estimates by assuming that all mining equipment is the best of the best, and that all electricity is relatively cheap (I understand some operations in China don't pay for electricity).
If there are any glaring mistakes, or major issues I've missed which could skew the result significantly, I would appreciate any help. Thanks.
 
ASSUMPTIONS:
   
CALCULATIONS:
Electricity Cost:
 
Depreciation Cost:
NOTE: I assumed a linear depreciation cost over 180 days useful life of the mining rig. I honestly don't know how long people keep miners (professional, not hobbyists). It does appear that new/better models come out about every 6 months though. It also appears that older mining rigs, at most 2 development cycles old, aren't cost effective. I didn't regard it as appropriate to this estimate to include the few 2 year old USB miners that some hobbyists are using in their basement or attic somewhere. Also, I've heard that some mining manufacturers mine with their new stock first before cleaning it up and sending out for sale, further hurting the ROI on older equipment.
 
Combining the Electricity Cost and Depreciation Cost together we get: (Network Electricity Cost Per Coin) + (Depreciation Cost per Coin) = ($43.30) + ($715.79) = $759.09
 
Property, Plant, and Labor Cost: This is tough and can have a lot of factors. I've written down many but to keep this post length somewhat reasonable, I'm going to simply add on a 15% additional cost to the previous total = (1.15) x ($759.09) =
 
So, the Global Total Mining Average Cost to collectively mine a bitcoin at 12.5 coins awarded per block is about: $872.95
 
As we can see, the Depreciation expense is the biggest factor in the estimate. Any adjustments to the assumption of mining equipments' usable life would significantly affect the estimate. Additionally, this estimate is basically a current "snapshot" of the mining landscape and doesn't include network growth and its effects on mining over time.
 
Again, this is just some napkin math I threw together from a base of assumptions and wasn't intended to be exact. I appreciate hearing any major faults you find in the assumptions or methodology and any suggestions you have regarding the numbers.

A Bitmain E3 miner has an advertised performance of 180 MH/s, so total network hashpower is equivalent to about 777777 E3 miners, which would cost roughly $800 million (though the exact cost could be quite volatile). This is how much one would have to invest to stage a 51% attack on ethereum network. If the network consists of only ETH and utility tokens, whose value would plummet if such an attack were to be successful, nobody is incentivized to do so. But (imagine sometime in the future), if the ethereum network has securities token contracts, whose underlying asset worth a total of a trillion dollars, then carrying out such an attack would seem quite profitable.
A new security economic model is clearly required for any public chain to run securities token. The biggest problem with ethereum, is that miners are not incentivized to contribute hashpower, as a function of total market cap of tokens running on ethereum. This is not a problem in the era of utility tokens, when they are worth significantly less than the main ethereum network. In the era of securities tokens however, this will become a significant risk, as securities tokens can easily worth several folds more than the public chain itself. We need to figure out a new economic model, where the public chain’s hashpower is a direct function of total token value running on the public chain.

Is the mining craze over?

In DecembeJanuary when bitcoin was ~$16000+ the Antminer S9 was very hard to find on ebay and the few used ones available were $4000+ Since 2-3 weeks ago you can find a used one for ~$1700 or less if bidding ($1800 original price) . For some reason altcoin mining took more time to react to crypto prices and only the last few days the price of a gtx 1060 3gb went from $300+ for a used one to ~$260 (~$180 original new price) With current ethereum price a gtx 1060 3gb makes only $0.75 a day. Hopefully we'll see a lot of sub $150 prices for used gtx 1060 3gb soon with "never mined on it" description

Selling my two S9s and two R4s. Anybody in Toronto GTA area is interested in buying them?

This is what I have ready to post on ebay.ca for one antminer S9. Questions/suggestions are welcome.
Title: BTC Antminer S9 12.93 TH/s (4 month old) in perfect condition + 2 power supplies.
Subtitle: You get everything you need to start mining right away.
Condition description: No hardware defects at all, all the ASIC chips are still working just fine (no zeros nor dashes). It has just some dust gathered with time which can be clean up easily by the buyer (or not, it's working pretty good right now).
Details: I'm adding a 15 Amps Power Bar, plus a 14 gauge 15 meters power cable, for free, so you won't waste any precious time with this machine, it's the most powerful and reliable one I have (from a total of 4). Not to mention that I will send you everything in the original box plus the other boxes for both power supplies and cables and power bar. About 4 boxes, so for the higher bidder let me know if you want to exclude some of these items so you will pay less shipping.
About me, I am a Bitcoin enthusiast and am involved with mining since 2011. I was a super happy miner until my life has turned 180 degrees this end of October with my father's death, so I am renting my house and ending things in Canada for a while and I will return to Brazil to take over my dad's/family farming business. Unfortunately I won't be able to take my miners with me to Brazil simply because the cost of 1kwh down there is up to 4 times more expensive than in Canada, making mining in Brazil really impossible.

30 Bitmain AntMiner S1 farm

I am looking to set up a Bitmain AntMiner S1 farm at a data center which would include 30 antminers each running at 180 gh/s(no overclocking for simplicity).This would result in about 5.4 TH/s of computing power at a cost of 43.5 bitcoins(https://ninjatech.org/index.php?route=product/product&product_id=54).If i was able to get everything up and running by the end of the month would it be worth my time;ive done some pessimistic calculations and they all seem good,any advice would be appreciated

Большой обзор: восемь самых доходных ASIC-майнеров криптовалюты

ASIC-майнер – специальное устройство, которое позволяют добывать криптовалюту. В отличие от графических карт (GPU), которые многофункциональны и могут пригодиться еще, например, для компьютерных игр, «асики» - однозадачны, они не могут ничего другого, кроме как майнить криптовалюту. Зато делают это максимально эффективно и обычно мгновенно вытесняют GPU из той сети, криптовалюту которой начинают добывать. Coinlife подготовил обзор самых известных ASIC-майнеров с учетом их доходности и окупаемости.
ASIC-майнер, в отличие от GPU, обычно рассчитан на добычу всего 1-6 криптовалют, без возможности резко перестроиться на любую другую валюту, что ограничивает майнера в выборе.
Но неоспоримым преимуществом майнинга с помощью ASIC-устройств является его сверхэффективность. Мощность одного устройства сравнима с одновременной работой десятков, а то и сотен GPU. Поэтому с началом выпуском ASIC-майнеров для добычи конкретной криптовалюты, хэшрейт в сети резко возрастает и майнинг с помощью других устройств перестает приносить доход их владельцам. Это особенно заметно в сети биткоин. Добыча главной криптовалюты мира давно выполняется только на «асиках». С них-то мы и начнем свой обзор.
SHA-256
Antminer S9
Antminer S9 - самый популярный и эффективный на сегодняшний день ASIC-майнер для добычи биткоина.
Производитель– Bitmain (Китай). Компания Bitmain известна, как лидер по производству майнеров для биткоина. Ей принадлежит порядка 70% рынка ASIС-майнеров для BTC. В линейке компании насчитывается уже несколько моделей устройств для добычи самой дорогой цифровой валюты. Самый известный и эффективный на сегодняшний день – Antminer S9. Он работает на алгоритме SHA-256, поэтому с его помощью можно добывать Bitcoin и Bitcoin Cash.

Хэшрейт отличается, в зависимости от партии, и варьируется в диапазоне от 11,5 до 14 TH/s. Энергопотребление также отличается в зависимости от значения хэшрейта: от 1127 Вт до 1372 Вт. Майнер работает на чипе BM1387, в одном устройстве насчитывается 189 чипов. Техпроцесс – 16 nm.
Цена устройства от производителя составляет 139 тыс. руб. (2 425 долларов) включая блок питания. Доходность в день примерно равна 10,3 долларам, это 0.001136 BTC (здесь и дальше данные указаны по состоянию на 28.02.2018 г., с учетом стоимости электроэнергии 4,5 руб. за кВт/ч).
Окупаемость устройства займет порядка 8 месяцев.
Ebit E9 Plus
Майнер биткоина от еще одного китайского производителя, пытающегося составить конкуренцию Bitmain, Zhejiang Ebang Communication Co., коротко - Ebit.
Устройство также работает на алгоритме SHA-256 и используется для добычи Bitcoin и Bitcoin Cash. Хэшрейт Ebit E9+ равен 9 TH/s при энергопотреблении в 1300 Вт. Работает на трех платах с чипом DW1227 (132 шт.). Техпроцесс – 14 nm.
Цена в Москве составляет от 120 тыс. руб. (2,2 тыс. долларов). Доходность в день 5,9 доллара, это 0, 000757 BTC.
Окупаемость составляет 12-13 месяцев.
Скоро ему на смену придет новый майнер Ebit E10, с хэшрейтом в два раза выше, и с меньшим энергопотреблением. Компания анонсировала выход нового устройства в конце 2017 года. Но отгрузки пока не начались.
AvalonMiner 741
Еще одно ASIC-устройство для майнинга биткоина и его самого успешного хардфорка. Производитель Canaan Creative CO., Китай.
Работает, соответственно, на алгоритме SHA-256. Хэшрейт составляет 7,3 TH/s. Энергопотребление 1150 Вт. Количество чипов A3212 в одном устройстве - 88 шт. Техпроцесс 16 nm. Майнер работает на двух платах.
Стоимость AvalonMiner 741 в Москве примерно равна 170 тыс. руб. (почти 3 тыс. долларов). Доходность в день составляет порядка 6,4 доллара – 0,0008 BTC.
Окупаемость такого вложения займет 15 месяцев.
X11
DM11G
Американский ASIC-майнер криптовалюты Dash. Производитель – iBeLink.co (США). Работает на алгоритме X11. Помимо основной валюты может использоваться для добычи Cannabiscoin (CANN) и Monoeci (XMCC). Хэшрейт 11 GH/s. Энергопотребление скромное 810 Вт. Работает на чипе TNB0303-FL28, в одном устройстве 64 шт. Техпроцесс – 28 nm. Стоит отметить, что данный майнер является одним из самых тяжелых. Вес составляет 22 кг.
Цена в Москве сейчас составляет порядка 110 тыс. руб. (1,9 тыс. долларов). Доходность в день – 2,5 доллара, это 0.0066 DASH.
Окупаемость 2 года.
Antminer D3
Более известный майнер Dash от Bitmain. Работает на алгоритме X11 и кроме Dash может добывать Cannabiscoin (CANN) и Monoeci (XMCC). Хэшрейт превышает показатели предыдущего майнера – 19.3 GH/s. Энергопотребление 1200 Вт. В каждом устройстве по 180 чипов X11.
На сайте компании продажа приостановлена на неопределенный срок. В Москве D3 можно купить примерно за 90 тыс. руб. Доходность в день порядка 5 долларов, это 0,0123 DASH.
Окупаемость вложений займет меньше времени – 10 месяцев.
Scrypt
Antminer L3+
Известный майнер Litecoin от китайского гиганта Bitmain. Работает на алгоритме Scrypt, поэтому кроме LTC может майнить Dogecoin (DOGE), Verge-Scrypt (XVG), DGB-Scrypt (DGB), GameCredits (GAME) и Einsteinium (EMC2). Хэшрейт майнера достигает 504 MH/s. Энергопотребление невелико – 800 Вт. Имеет чип BM1485, в одном устройстве таких 288 шт. Техпроцесс 16 nm.
На официальном сайте продажи открыты. Цена составляет 1500 долларов США (86 тыс. руб.) вместе с блоком питания. Стоимость оборудования в Москве составляет 150 тыс. руб. В день L3+ приносит 9,3 доллара дохода, это 0,051 LTC.
Окупаемость – 10 месяцев, если вы купили оборудование в Москве и 6 месяцев, если вам удалось купить по цене производителя.
A6 LTCMaster
Майнер Litecoin от другого китайского производителя INNOSILICON Technology Ltd. Набор валюты, которую можно добывать с помощью этого устройства, аналогичен предыдущему. Хэшрейт выше в два раза – 1,23 Gh/s. Энергопотребление, соответственно, тоже заметно отличается и составляет 1500 Вт.
Цена производителя составляет – 6,3 тыс долларов США. В Москве устройство можно приобрести за 450 тыс. руб. Доходность в день 23 доллара - 0.1227 LTC.
Окупаемость майнера составляет 11 месяцев.
Blake (2b)
Antminer A3
Новый майнер от уже упоминаемого производителя Bitmain. Выпущен был только в январе 2018 года. Создан для майнинга Siacoin. Bitmain сработал на опережение и создал майнер раньше, чем компания Obelisk – «дочка» Sia. Многие участники сообщества Sia выступили даже за проведение софт-форка сети, который сделал бы невозможным майнинг Siacoin с помощью Antminer A3. Но от этой идеи отказались и оба производителя пришли к соглашению о совместной работе по развитию сообщества SIA.
Читать еще: Siacoin получил из Китая импульс к развитию: обзор криптовалюты
Майнер работает на алгоритме Blake (2b). Хэшрейт равен 815 MH/s. Энергопотребление составляет 1275 Вт. Количество чипов BM1720 в одном устройстве – 180 шт. Техпроцесс 16 nm.
Цена на сайте производителя указана в долларах – 2,37 тыс., в Москве новое устройство обойдется в 240 тыс. руб. Доходность составляет 37,7 долларов в день, 1,8 тыс. Siacoin.
Окупаемость одного устройства по данным на момент публикации составляет всего 2 месяца. Но с учетом роста хэшрейта, ситуация совсем скоро может измениться.
В наш обзор ASIC-майнеров вошли самые известные и доходные устройства. Рынок ASIC-майнеров гораздо шире, разнообразнее. Конкуренция велика. На 2018 год запланирован выпуск сразу нескольких новых моделей оборудования для майнинга криптовалют. Ожидается выход на рынок устройств от Samsung, корпорация намерена наладить выпуск чипов для ASIC-майнеров. Добытчики биткоина с нетерпением ждут новинки от Bitmain, которая придет на смену Antminer S9.

To mine or not to mine @ .02/kWh?

I'd like to buy two Antminer s5's and run those at my current electricity rate of .02/kWh (special residential rate). I am not trying to get rich but assuming we stay above 200 for bitcoin, will this be profitable after buying miners and power supply?
I want to cut these machines on and be apart of the movement. I am ok with losing 100% of investment.
> or < 180 day payoff? 
Thanks,

With difficulty skyrocketing why not mine Terracoin or other sha-256 coins?

The difficulty of bitcoin is going up at about 20% ever week and a half. Which means that in 100 days a 180 Gh/s Antminer-S1 goes from nearly $16/day to $4.6/day. You'll end up making a few hundred on each machine.
Wouldn't it make more sense to mine terra or peercoin because they're difficulties are staying lower? My 180 Gh/s will stay a larger percentage of the total hash for longer with them than bitcoin.
Or should I expect the btc/alt coin to fall in correlation with their btc hash/alt hash?

    1. u/jessquit to u/nullc "You're so fucking shameless, devoting your career to crippling one of the most disruptive inventions since the Internet to please your investment team. Watching you go down in flames will be one of the great moments in computer science. Your legacy will be a monument of shame" (214 points, 40 comments)
    2. Suggestion for new terminology. Instead of saying "small blocks" vs "big blocks", we could say: "centrally planned blocksize" vs "market-based blocksize". This will make it clear that some solutions are based on markets and economics, and other solutions are based on central planning. (195 points, 64 comments)
    3. Core/Blockstream is living in a fantasy world. In the real world everyone knows (1) our hardware can support 4-8 MB (even with the Great Firewall), and (2) hard forks are cleaner than soft forks. Core/Blockstream refuses to offer either of these things. Other implementations (eg: BU) can offer both. (180 points, 35 comments)
    4. Letting FEES float without letting BLOCKSIZES float is NOT a "market". A market has 2 sides: One side provides a product/service (blockspace), the other side pays fees/money (BTC). An "efficient market" is when players compete and evolve on BOTH sides, approaching an ideal FEE/BLOCKSIZE EQUILIBRIUM. (153 points, 42 comments)
    5. Previously, Greg Maxwell u/nullc (CTO of Blockstream), Adam Back u/adam3us (CEO of Blockstream), and u/theymos (owner of r\bitcoin) all said that bigger blocks would be fine. Now they prefer to risk splitting the community & the network, instead of upgrading to bigger blocks. What happened to them? (149 points, 66 comments)
    6. "Negotiations have failed. BS/Core will never HF - except to fire the miners and create an altcoin.

    7. Who owns the world? (1) Barclays, (2) AXA, (3) State Street Bank. (Infographic in German - but you can understand it without knowing much German: "Wem gehört die Welt?" = "Who owns the world?") AXA is the #2 company with the most economic poweconnections in the world. And AXA owns Blockstream. (119 points, 182 comments)

    9. The Bitcoin community is talking. Why isn't Core/Blockstream listening? "Yes, [SegWit] increases the blocksize but BU wants a literal blocksize increase." ~ u/lurker_derp ... "It's pretty clear that they [BU-ers] want Bitcoin, not a BTC fork, to have a bigger blocksize." ~ u/WellSpentTime (90 points, 41 comments)
    10. Just because something is a "soft fork" doesn't mean it isn't a massive change. SegWit is an alt-coin. It would introduce radical and unpredictable changes in Bitcoin's economic parameters and incentives. Just read this thread. Nobody has any idea how the mainnet will react to SegWit in real life.

    7. after days , segwit signaling is oscillating between 15-25% . that's a far cry from what blockstream core was expecting . if they were ready to label a 10% resistance ' blockers' , now they will have to come to terms with the fact that thir proposal is simply not good enough .

    1. Another successful hard fork by Ethereum occurred today. Protocol upgrades are possible. Don't listen to lies from entrenched interests that say otherwise. (202 points, 78 comments)
    2. I think if it comes down to it, Core would rather remain in control, even if it means introducing a small blocksize increase, as opposed to losing control entirely. We should not lose sight of our larger goals no matter what carrots they throw our way: We need a new, un-corrupt dev team. (177 points, 65 comments)
    3. Bitcoin Core Devs can't just say the price of Bitcoin should be stuck at $100 per coin. The market decides. Just like Core shouldn't say the size of a block is stuck at 1MB. The market should decide! Take centrally planned actors OUT of the equation. This is Bitcoin-- Not the Federal Reserve. (145 points, 39 comments)
    4. Segwit cannot be rolled back because to non-upgraded clients, ANYONE can spend Segwit txn outputs. If Segwit is rolled back, all funds locked in Segwit outputs can be taken by anyone. As more funds gets locked up in segwit outputs, incentive for miners to collude to claim them grows. (120 points, 34 comments)
    5. Miner Jiang Zhou'er: "I can conclude with great confidence: SegWit will never ever be activated. Even in 75% or 51% scenarios it will not be alive. ..some people are destined to be nailed up on the pillar of humiliation." (95 points, 63 comments)

    7. No one (except the market) knows what the price of Bitcoin should be, just like no one (except the market) knows what the size of blocks should be. Bitcoin Unlimited allows a market-decided blocksize. Bitcoin Core allows a centrally planned blocksize. (74 points, 20 comments)
    8. MYTH: "Bitcoin Unlimited isn't meant for mining." -- FACT: ViaBTC has been mining with BU and has the best performance of ALL pools. [see link inside] (71 points, 61 comments)
    9. It is likely a Core-affiliated extremist will attack pools mining Bitcoin Unlimited blocks. I recommend Bitcoin.com Pool goes live ASAP, with over 10% hashrate, so we have multiple pools for redundancy. 10-12% hashrate is not enough in the face of attackers who try to artificially activate Segwit.

Want to get into Bitcoin and cryptocurrencys and looking for help.

Hi everyone. I'm looking to get into learning about cryptocurrencys and experimenting with mining them. I'm planning on getting a raspberry pi for Christmas and hooking up some USB block Eruptors. I know I won't get a good roi but what would be the best USB device to get? Can anyone tell me some insight on these? And which one I should get.
