Ethereum hashrate sets record

On October 6, the hash rate of the Ethereum network reached an all-time high of more than 250 terahashes per second, which is 80% higher than the levels in January.
Glassnode noted that this was facilitated by a surge in hype around DeFi projects, which caused an increase in gas prices. Last time such a high hash rate was in the summer of 2018, then ETH was also trading slightly above the $400 mark.
In addition, mining ethereum is now three times more profitable than bitcoin. According to the F2Pool mining pool, owners of Antminer S19 Pro devices can earn $4.33 per day, while ETH miners using NVIDIA GTX Titan V cards can expect to earn $15.56.

Bitcoin Hashrate Has Hit a New Record-High Again, Here's Why It's Optimistic

The total hash rate of the Bitcoin blockchain network has hit an all-time high, demonstrating an optimistic after the halving. Bitcoin’s third block reward halving in history occurred on May 11, 2020. Immediately after, its hash rate dropped from 121 million terahash per second (TH/s) to 90 million TH/S. The rapid recovery of Bitcoin’s hash rate shows that the mining sector is healthy, which could lead to market stability. A positive catalyst for Bitcoin in the medium-term Following a block reward halving, the hash rate of the Bitcoin network tends to drop substantially. The halving drops the amount of BTC miners can produce by half, causing their revenues to decline. When miners struggle with recurring expenses as a result of lower BTC production, they typically sell their BTC reserves. In the short-term, until a major difficulty adjustment occurs, the risk of miner capitulation or massive selling pressure is low. Alejandro De La Torre, the vice president of Poolin, explained that older machines have become profitable as well. That means even individual miners could be profitable and are likely less compelled to sell BTC. Torre explained: “Yesterday's two-week difficulty re-adjustment saw a decrease of - 2.87% & an average hash rate of 120.57 EH/s. What's interesting here is that the hashrate continues to increase, definitely related to the current #bitcoin price - older machines are profitable again.” Consequently, Torre said the hash rate of the Bitcoin network would likely continue to increase. The difficulty to mine BTC is lower than in previous weeks, and the price of BTC is above $11,000. He noted: “Difficulty is now lower than the last two weeks from 17.35T to 16.85T and the price is much higher so expect strong hashing for the next two weeks, all dependent of the price at the end of the day.” A record-high hash rate merely three months after the halving can be considered an optimistic trend. It shows that due to varying factors, which includes cheaper electricity in Sichuan, China, the mining industry is stable. Many large mining centers are based in Sichuan. Due to the rainy season and the presence of hydropower plants, lower-cost electricity is available for miners. Optimistic market cycle According to data from ByteTree, the net inventory of miners over the past five weeks is hovering at 30 BTC. The data shows that miners have not sold more than they mine, which leads to less selling pressure on BTC. Relatively low selling pressure from miners is a positive factor that could allow BTC to sustain its strong momentum. It also indicates that Bitcoin is on track to recover from the halving before the fourth quarter of this year, demonstrating the resilience of the sector.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.

[Researh] In 2017 bitcoin network consumed 5 TWh of energy, in 2018 – 29 TWh, in 2019 – 43 TWh. Banking industry consumes 74 TWh per year.
Electricity consumed by bitcoin network has been constantly and noticeably increasing. During the past years the consumption reached such big a scale, that it can be compared to electricity consumption of some countries, according to BlockchainAnalytics.pro research.
The world’s first cryptocurrency is steadily becoming more popular and expensive every year. This motivates more individuals and companies to enter the mining business to earn a bitcoin share.

More miners, more efficient equipment

To validate a block of transactions and receive a reward, miners compete with each other by solving a deliberately complicated mathematical task, or puzzle. Those miners who own more computing power (hashrate) have more chances to win the competition. This incentivizes miners to buy more powerful equipment that consumes more electricity.
At the same time, mining equipment efficiency is constantly improving, and with time less electricity is required to produce the same hashrate. This factor allows to slow down the increasing demand for electricity.
For example, in 2016 Bitmain, world’s largest manufacturer of mining equipment, launched the legendary Antminer S9, which consumed 100 watts to produce one terahash per second, or 100 W/TH/s. The best modification of Antminer S15, released in 2018, consumed 57 W/TH/s. Currently, the most efficient Antminer S17 consumes only 40 W/TH/s.
https://preview.redd.it/gh343l3p09j41.png?width=930&format=png&auto=webp&s=e350c1e7832e37c1e3c3aeac974428cca7f0f874
It is assumed that the market competition compels manufacturers to keep up with each other in developing more efficient hardware. If some manufacturer brings next-generation chips to market, other manufacturers start to produce chips with the same characteristics at about the same time.
On the other hand, new miners are joining the network, thus increasing the hashrate. So the demand for electricity continues to grow. Also, it can be noticed later that the electricity consumption chart is similar to that of hashrate chart.
https://preview.redd.it/3k32ci6q09j41.png?width=930&format=png&auto=webp&s=e70f600419bcbc9e7e82506b5f12bf4da6f00584

Calculations

The incremental volume of electricity consumption is calculated by multiplying newly added hashrate by the best mining efficiency available at that moment.
The sum of incremental volumes represents cumulative amount of electricity consumed by bitcoin network. The metric is expressed in terawatt-hours (TWh). To get annualized volume in terawatt-hours we multiply the consumption by 24 hours and 365 days.
A 100-day moving average was applied to hashrate to make the final result less dependent on the short-term hashrate fluctuations.
Assumptions, used in this study, are very conservative. It means that the results are in the lower limit of the range of possible volumes, and the actual electricity consumption can be higher.
A detailed explanation and interactive charts are provided here: https://www.blockchainanalytics.pro/btc/electricity-consumption/

Results

Currently, annualized electricity consumption in bitcoin network is 57 TWh. To help readers get an idea of how much electricity the bitcoin network consumes, a comparison with some countries is provided alongside.
Portugal consumes 49 TWh per year, Romania – 50 TWh, Czech Republic – 59 TWh.
Some more numbers for comparison:

According to conservative estimates, the bitcoin network will consume more than 70 TWh in 2020. This is on a par with Chile, a country with 18 million population.

More thoughts (estimations of how much energy banking industry consumes)

Some information from official reports:
Taking into account the information above, we can assume that, on average, banks spend ~20 kWh per customer per year.
Some information on world population:
  • 69% of adults around the world have a banking account (source)
  • 70% of the world population are adults (source)
  • World population is 7.7 billion (source)
Finally: 7.7 billion people * 70% * 69% * 20 kWh per year = ~74 TWh per year
So, we can assume, that banking industry consumes ~74 TWh per year

Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead

The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty.
Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output.
The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector?
T19: The cheaper S19
According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster.
Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour.
Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph:
“When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph:
“ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.”
Hardware problems and competitors
The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units.
Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts:
“Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.”
“I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%.
Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader.
Will the hash rate be affected?
Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug.
The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October.
The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network?
Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph:
“There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle
At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph:
“Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines.
As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl.
“Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up.
Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing.
Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.

Bitcoin Mining Unit Manufacturer MicroBT Nibbles at Bitmain’s Market Share

Bitcoin Mining Unit Manufacturer MicroBT Nibbles at Bitmain’s Market Share


Bitcoin miner maker MicroBT has rapidly expanded market share by selling over half a million units in 2019, chipping away at rival Bitmain's dominance.
MicroBT sold about 600,000 units of its flagship WhatsMiner M20 series last year, Vincent Zhang, sales head of the Shenzhen-based company, said in an online panel hosted by Chinese mining pool Poolin on Thursday in a WeChat group.
These products generate a computing power of about 60 terahashes per second (TH/s) on average, he said. That means the newly delivered 600,000 units may have contributed over 30 exahashes (EH/s) of hashing power to the bitcoin network in 2019. (1 EH = 1 million TH).
Amid bitcoin's price jump throughout 2019, the network's two-week average computing power more than doubled from just 40 EH/s around the end of 2018 to nearly 100 EH/s in December. That'd mean close to half of bitcoin's computing power growth in 2019 may have come from equipment delivered by MicroBT.
Zhang didn't specify the precise average unit price of these batches, as they could fluctuate depending on bitcoin's price over the year. But the firm's various models in its M20 product line are generally priced between $24 to $30 per terahash, meaning the firm has brought home a high nine-figure revenue in U.S. dollars for 2019.
Bitcoin's current computing power stands at 110 EH/s. That also means MicroBT may account for around 30 percent of bitcoin mining power sold right now, making it one of the largest and fastest-growing miner makers in the world.

TERA CRYPTO CURRENCY PROJECT

TERA is an open source and collaborative project. It means everyone can view and eventually modify its source code for hehis own needs. And it also means anyone is welcome to integrate its working community. The Tera community works to develop, deploy and maintain Tera nodes and decentralized applications that are part of the TERA Network.
The TERA technology serves the cryptocurrency concepts, trying to design a modern coins and contracts blockchain application : fast block generation, high transaction throughput and user-friendly application. It was officialy launched on 30th of June 2018 on the bitcointalk forum.
[Yuriy Ivanov](mailto:[email protected]) is the founder and core developer of the project. The Tera community is more familiar with the alias « vtools ».

USER FRIENDLY APPLICATION

In the aim to make this crypto currency project more friendly to end-users, some interesting innovations have been implemented in regards to the first generation of crpyto currency applications. The bitcoin and its thousands of child or fork, required a good level of IT skills in order to manage all the application chain from its own : from miners and its hardware, through stratum servers, proxies, to blockchain nodes. The Tera project intend to go one step further regarding crypto currency features integration into a single application : once installed, an efficient web application is available on localhost on port 8080. Then, any web browser supporting javascript may be able to access this application and to operate fully the Tera node.

MINING A CRYPTO CURRENCY

MINING CONCEPT

The mining activity consist in calling a mathematical procedure we can’t predict the result before we run it. But we intend to obtain a very specific result, which usually consist in a certain number of 0 as the first chars before any random answer. If we found the nonce (a random object) combined with the transaction data and the coin algorithm that produce such result, we’ll have solve a transaction block and we’ll get a reward for that. Thanks to this work, the transaction listed in the block will be added to the blockchain and anyone will be able to check our work. That’s the concept of ‘proof of work’ allowing anyone to replay the mathematical procedure with the nonce discovered by the node that solved the block and to confirm block inclusion into the blockchain.

POLITICAL AND ETHICAL CONSIDERATIONS

The Tera project is young. It will have to face the same problems is facing today the Bitcoin platform :
Any Crypto Currency Project with the goal its money and contracts to be used as any other historical money or service contract has to consider its political and ethical usage. Processes have to be imagined, designed and implemented in order to be able to fight against extortion, corruption and illegal activities threating crypto-currency development.

FAST BLOCK GENERATION AND HIGH THROUGHPUT

CLASSIC CRYPTO CURRENCY FEATURES

wallet, accounts, payments, mining, node settings and utilities, blockchain explorer and utilities…

DECENTRALIZED APP CATALOGUE

d-app : forum, stock exchange, payment plugins for third party platform, …

TECHNOLOGY DEPENDENCIES

Tera is entirely written in Java) over the NodeJS library as functional layer in order to take advantages of a robust and high level library designed to allow large and effective network node management.
The miner part is imported from an external repository and is written in C in order to get the best performances for this module.
Tera is actually officially supported on Linux and Windows.
If you start mining Tera thanks to this article, you can add my account 188131 as advisor to yours. On simple demand I’ll refund you half of the extra coins generated for advisors when you’ll solve blocks (@freddy#8516 on discord).

MINING TERA

Mining Tera has one major design constraint : you need one public IP per Tera node or miner. Yet, you can easily mine it on a computer desktop at home. The mining algorithm has been designed in order to be GPU resistant. In order to mine Tera coin you’ll need a multi-core processor (2 minimum) and some RAM, between 1 and 4GB per process that will mine. The mining reward level depends of the « power » used to solve a block (Top Tera Miners).

COST AND USAGE CONSIDERATIONS

There is two main cost centers in order to mine a crypto currency :
  1. the cost of the hardware and the energy required to make a huge amount of mathematical operations connected to the blockchain network through the Internet,
  2. the human cost in order to deploy, maintain and keep running miners and blockchain nodes.
As the speculation actually drives the value of crypto currencies, it is not possible to answer if the mining activity is profitable or not. Moreover, hardware, energy and human costs are not the same around the globe. To appreciate if mining a crypto currency is profitable we should take all indirect costs : nature cost (for hardware and energy production), human cost (coins and contracts usage, social rights of blockchain workers).

Bitcoin Costs $1.4 Billion to 51% Attack

Calculations and Math (Nov 29, 2018)
Fixed Costs:
The 7 day average of the Bitcoin network hash rate, as of November 23rd 16:00 UTC, is 41,483,931 terahashes. https://www.blockchain.com/en/charts/hash-rate
To acquire more than 50 percent of the Bitcoin network, an attacker would need at minimum the same number of ASICs that are already in circulation.
Network hash rate / terahashes per ASIC = number of ASICs necessary to acquire 50 percent * 41,483,931 network terahashes / 14 terahashes = 2,963,138 S9is * 41,483,931 network terahashes / 23 terahashes = 1,803,649 T15s
Calculations for total current ASIC usage: 2,963,138 * 1.75 (crude estimate accounting for older models) = 5,185,492
Including bulk discount of 10 percent for the size of the purchase and economies of scale.
Infrastructure costs such as housing are a multiple of hardware costs from anywhere between an additional 22 percent to 40 percent, according to the CEO of a large-scale mining operation based in Canada. We will use the low figure to again account for economies of scale.
Variable Costs:
Costs of daily electricity consumption for S9i: * 2,963,138 ASICs * 1320W = 3,911,342,160 Watts * 3,911,342,160 Watts / 1000 = 3,911,342 kWh * 3,911,342 kWh * 24 hours = 93,872,212 kWh per day * 93,872,212 * $0.03 per kWh = $2,816,166 per day in electricity Electricity costs based the low-end of the electricity rates in Washington State, the state with the average lowest electricity costs in the United States: https://www.electricitylocal.com/states/washington/
Costs of daily electricity consumption for T15: * 1,803,649 T15s * 1541 Watts = 2,779,423,109 Watts * 2,779,423,109 Watts / 1000 = 2,779,423 kW * 2,779,424 kW * 24 hours = 66,706,155 kWh * 66,706,155 kWh * $0.03 per kWh = $2,001,185 per day in electricity
Cost of labor and maintenance above electric costs: 10%. This is an estimate based on an interview with two different large-scale miners in Canada and Georgia who chose to remain anonymous.
Average kWh: ((((3,911,342,160 Watts + 2,779,423,109 Watts) / 2) * 24 hours) * 365 days) / 1E12 watt hrs per terawatt hrs = 29.3 TWh
This estimate is short of Denmark’s oft-cited annual energy consumption of 32 TWh, closer to Morocco's consumption of 29 TWh.
Total Costs:
51% attack may require at least 10 days of sustained mining, at a minimum, based on the recent Bitcoin Cash hash wars:
Total cost of S9i attack: $971,814,740 + $30,977,820 = $1,002,792,560 Total cost of T15 attack: $1,808,111,227 + $22,013,740 = $1,830,124,967
Average cost of an attack: ($1,002,792,560 + $1,830,124,967) / 2 = $1,416,458,764

Haobtc.com's New Hashrate Exchange....Breakeven cloud mining in 9 months?

Hey guys,
So Haobtc.com has a new hashrate exchange where you can buy Terahash's of their network and collect your share of the mining profit on a daily basis.
Nothing terribly new, I know, but I have an account there and was curious what the implied breakeven point would be and it looks like due to their dirt cheap electricity from being located in China, their breakeven based on current prices per Terahash and recent profit / Terahash levels is about 9 months.
Is this considered "good?" I'm not sure. In looking at some other non-China based cloud mining exchanges, they are advertising potential breakeven at 14 months or more.
What do you guys think? Work looking into as a potential BTC investment? Going to be able to wait it out for 9 months, collect your buy-in, and then just collect your daily pure profit from then on?
For what it's worth, I live in China but as an American expat and was still able to open/use my Haobtc account without any problems.

SQUIRE ENTERS INTO NON-BINDING LETTER OF INTENT AND EXCLUSIVE NEGOTIATIONS REGARDING ACQUISITION OF COINGEEK.COM AND 1.0 MILLION TH/S OF MINING ASSETS, FORMING THE LARGEST PUBLIC CRYPTO MINING COMPANY, AND NAME CHANGE TO “COINGEEK TECHNOLOGIES LTD.”

VANCOUVER, British Columbia, Nov. 30, 2018 (GLOBE NEWSWIRE) — Squire Mining Ltd. (CSE:SQR | FWB:9SQ | OTCQB:SQRMF) (“Squire”) is pleased to announce today it has entered into a non-binding letter of intent (the “Agreement”) and exclusivity with Bigfoot Holdings Group Ltd. (c.o.b. as CoinGeek Mining & Hardware) (together with its affiliates, “CoinGeek”) to purchase crypto mining assets owned by CoinGeek and certain of its affiliates representing approximately 1 million terahash/s of computing power (or approximately 960 petahash/s) and other blockchain related assets (the “Assets”), for total consideration of approximately CAD$60.3 million consisting of (i) 114,793,565 common shares of Squire, having a value of CAD$34.4 million based on the closing price of Squire’s common shares on the Canadian Stock Exchange (“CSE”) on November 29, 2018 of CAD$0.30 per share, and (ii) a vendor-take-back note in the amount of CAD$25.8 million, subject to adjustment at closing (the “Transaction”).
The Assets
The Assets consist of 62,440 ASIC mining rigs, representing approximately 960,000 terahash/s, or approximately 90.0 MW of power consumption, which, upon closing, would make Squire the largest publicly traded crypto mining company globally, as measured by terahash/s. The Assets are all operated by leading hosting providers and are allocated across the United States (35,940 rigs), Canada (6,000 rigs) and Kazakhstan (20,500 rigs). The all-in weighted average operational cost across the Assets being acquired in the Transaction is US$0.073 per kWh.
As part of the Transaction, Squire would also be taking on employees and consultants of CoinGeek involved with the management and operation of the assets and acquiring the marketing and advertising assets related to the CoinGeek name including the “CoinGeek.com” website and domain, existing prepayments made to and deposits with the respective hosting partners, as well as CoinGeek’s outstanding global distribution agreement for Squire’s ASIC chips and rigs.
Furthermore, as part of the Transaction, Squire would have a twelve-month right of first refusal to acquire CoinGeek’s remaining crypto mining assets.
“This Transaction would provide Squire with a leading, recognized brand via the acquisition of the CoinGeek.com and CoinGeek name, but it would also make us the largest, publicly traded Bitcoin miner globally. It is expected to deliver significant shareholder value by enabling Squire to become vertically integrated with our growing chip design and manufacturing business, which we would seek to have commercial within 2019,” said Taras Kulyk, Chief Executive Officer of Squire.
“I believe the next phase of growth for this industry is upon us and that means massive scaling of the Bitcoin blockchain to accommodate the throughput needed for enterprises to make use of this technology. By vending my mining and CoinGeek branded assets into Squire, I would be doubling-down on my commitment to Bitcoin’s success. These assets would enable Squire Mining Ltd to compete at a global level to pave a path for enterprise usage of blockchain technology to flourish,” said, Calvin Ayre, owner of the CoinGeek brand.
The Consideration
As noted above, CoinGeek would receive approximately 114.8 million common shares of Squire as partial consideration for the Assets. CoinGeek has agreed to enter into a voluntary one-year lock up on the common shares received. In addition, CoinGeek will receive an unsecured vendor-take-back (“VTB”) with a face value of CAD$25.8 million, a one-year term and a coupon of 15.0%. The principal amount of the VTB will be adjusted at closing of the Transaction (the “Closing”) to reflect any prepayments or prepaid deposits made in respect of the Assets between the signing of the Agreement and the Closing and by the amount (multiplied by CAD$0.45 per common share) by which the common shares to be issued would have exceeded the common share issued pursuant to the Transaction. In connection with a change of control, CoinGeek would be able to convert the VTB into common shares of Squire, with the number of common shares being equal to the principal amount and any accrued interest payments of the VTB divided by the then market price of the Squire common shares (based on a 30 day volume-weighted average), subject to a discount equal to the lesser of (i) 25%, and (ii) the maximum discount permitted under the policies of the CSE (or such other exchange as the Squire common shares may then be listed).
With the launch of Bitcoin SV (BSV), the Squire team is confident that this Transaction would be just the beginning as the company scales to match the anticipated enterprise-level and large volume usage of BSV’s cryptocurrency and blockchain. The BSV roadmap aims to enable massive on-chain scaling, and outlines for the crypto mining sector why that is important for the entire interrelated Bitcoin ecosystem. Much bigger blocks are needed to support higher commercial transaction volume, allowing miners to earn more transaction fees, which is critical for miners to stay profitable as Bitcoin’s block reward halves in 2020 and every several years after that. This is why BSV’s plan will in-turn drive growth in the mining hardware sector, reinforcing the Squire team’s optimism on future growth prospects.
Transaction
In addition to the negotiation and execution of definitive agreements between Squire and CoinGeek, the Transaction would be subject to a number of conditions, including, among others, (i) Squire being satisfied, in its sole and absolute discretion, with the results of its due diligence review in respect of the Assets, (ii) receipt of the conditional approval of the CSE, (iii) the Transaction not being subject to shareholder approval , (iv) receipt of required consents; and (v) execution of third party software licensing agreements in respect of the Assets. The letter of intent is non-binding and there is no assurance that the Transaction contemplated by it will be completed as proposed or at all.
The parties will seek close the Transaction on or about January 31, 2019. In conjunction with the Transaction, Squire intends to change its name to CoinGeek Technologies Ltd. and its fiscal year end from October 31 to December 31. The parties have agreed to an exclusivity period in the letter of intent ending on December 31, 2018, or such other date as the parties may mutually agree.
Canaccord Genuity Corp. is acting as exclusive financial advisor to Squire in respect of the Transaction.
Upon closing of the Transaction, Calvin Ayre, through the Antiguan Corporation Bigfoot Holdings Group Ltd. (“BHG”), would beneficially own or control 126,418,565 common shares of Squire representing approximately 53.3% of the issued and outstanding Squire common shares. The Squire common shares would be acquired by BHG for investment purposes only. Depending on market and other conditions, or as future circumstances may dictate, BHG may, from time to time, and subject to any contractual lock-up agreements (including the lock-up to be entered into in connection with the Transaction), increase or decrease its holdings of Squire common shares or other securities of Squire in accordance with applicable securities laws.
