Heat tolerance

The company confirmed in an announcement made on Thursday that the state-of-the-art air-cooled Bitcoin miner will ship during the first quarter of 2024. The Antminer T21 is expected to make waves in the world of cryptocurrency mining given that it can withstand scorching temperatures of up to 45 degrees Celsius.

During a facility tour, the firm tweeted out on Friday: “Although it is so hot here, ANTMINER is still running stable!”

The context of the comment relates to an installation of the new miner’s predecessor at a Moonwalk Systems facility in the arid heat of the United Arab Emirates (UAE). Moonwalk is utilizing water cooling to overcome the local conditions. However, it’s in environments like this one that Bitmain is likely to envisage its latest Antminer performing well.

 

Energy efficiency

Another standout feature of the Antminer T21 is its energy efficiency. With a stellar energy efficiency ratio of 19 joules per terahash (J/TH), it outpaces its predecessor, the Bitcoin Miner S21 Hyd, which offers an energy efficiency of 16.0 J/TH. This efficiency means miners can maximize their returns while minimizing their energy costs. Additionally, the Antminer T21 boasts an impressive processing power of 190 terahashes per second (TH/s), a crucial factor in the competitive world of Bitcoin mining.

The compatibility of the Antminer T21 with the SHA256 mining algorithm, used in the proof-of-work (PoW) consensus mechanism for cryptocurrencies like Bitcoin, Bitcoin Cash, and Bitcoin SV (BSV), adds to its appeal.

Notably, Bitmain has extended a helping hand to pre-order buyers of the Antminer T21 by offering Bitmain’s Price Protection Plan. This plan, available until November 25, aims to support miners in times of cryptocurrency market volatility. The plan shields customers from price fluctuations in Bitcoin for periods of one, three, or six months.

 

Company difficulties

Founded in Beijing in 2013, Bitmain swiftly rose to prominence as a global leader in producing Bitcoin (BTC) mining ASICs. However, the company faced internal turmoil due to a power struggle between its co-founders, Wu Jihan and Ketuan Zhan. The situation was eventually resolved in 2021, with Jihan Wu stepping down from his roles as chairman and CEO of Bitmain and selling his ownership share to Zhan for $600 million.

ASIC miner manufacturers like Bitmain have also had to grapple with the backdrop of a challenging market environment that has seen plummeting prices paid for mining equipment over the past two years.

Bitmain has faced scrutiny regarding its treatment of employees. Recent reports from local sources and Bitmain employees revealed that the company issued a notification in September indicating negative operating cash flow. In response to these financial challenges, Bitmain delayed the disbursement of a portion of its employees’ September salaries, raising concerns about the financial stability of the organization. In April of this year, it emerged that the Chinese authorities had imposed a fine on the company due to tax irregularities.

Mt.Gox creditors start to confirm receipt of first repayments

It's been nearly ten years since the infamous collapse of the Japanese bitcoin exchange Mt. Gox, with some creditors of the defunct business now claiming to have finally received their long-awaited repayments.Photo by Su San Lee on UnsplashSubreddit payment confirmationsTestimonies shared on the Mt.Gox creditor subreddit and a dedicated Telegram channel reveal that certain payments, in the form of Japanese yen, have been distributed to creditors who opted for PayPal as their preferred mode of receipt. Excitement marked the early stages of this repayment process. Users on Reddit joyfully shared their experiences, with one exclaiming:"I got money!! I just got my initial payment via Paypal!!"This development comes after Mt.Gox rehabilitation trustee, Nobuaki Kobayashi, had previously extended the repayment deadline from Oct. 31, 2023, to Oct. 31, 2024. However, last month, Kobayashi informed creditors that certain cash repayments would be initiated before the year's end. Despite efforts to expedite the process, the sheer volume of creditors and the complexities involved mean that repayments will continue into 2024. The collapse of Mt.Gox in early 2014 triggered global regulatory responses and initiated a nearly decade-long bankruptcy and corporate rehabilitation process. The exchange fell victim to a series of hacks between 2011 and 2014, leaving a lasting impact on the cryptocurrency landscape. The commencement of repayments has been hanging over the crypto market for many years, with many fearing that the process may have a dampening effect on the bitcoin unit price, given that funds are being distributed in Japanese yen and bitcoin. Earlier this year, the U.S. government indicted two Russian nationals for laundering funds stolen from Mt.Gox, shedding light on the enduring legal ramifications stemming from the exchange's demise. Double payment glitchHowever, it appears the process encountered some glitches, as other Reddit posts indicated that a few creditors received double payments via PayPal, adding a new layer of complexity to the already intricate Mt. Gox saga. Reddit users, such as u/rlycreativename, have shared emails they claim to have received from the Mt.Gox Rehabilitation Trustee. The emails acknowledge a system issue leading to inadvertent double transfers and legally obligate recipients to return the surplus amount. While some users have complied with the request and returned the duplicated funds, others have expressed hesitancy, citing the historical challenges creditors faced in obtaining their money. The situation has evoked discussions on Reddit, with users debating whether the Trust deserves a swift return, considering the prolonged struggle creditors endured to reclaim their funds. While it may be tempting for some creditors to hold on to the duplicate payment, such a decision may only serve to heap more misery on long-suffering Mt.Gox creditors. The recent case of Jatinder Singh and Thevamanogari Manivel would be very relevant for creditors to consider. Singh was a customer of well-known digital assets platform Crypto.com. In 2021 the firm inadvertently transferred $10 million to his account. Singh conspired with Manivel to withdraw and keep the funds. A community corrections order of 18 months has been imposed on Manivel in Australia while Singh will be sentenced in February.

These types of early ventures are inextricably linked to the rise of cryptocurrency exchanges.Kim went on to underscore Korea’s prowess in the gaming industry, mentioning popular games like Dungeon Fighter Online, MapleStory, and PlayerUnknown’s Battlegrounds (PUBG). He noted that many local game developers have already established Web3 studios and are actively preparing to transition to the world of Web3 gaming. The K-pop industry has also been incorporating Web3 technology in various projects.Merging hemispheresHashed has been actively investing in projects since 2016, with over 150 projects in its extensive portfolio. Of these projects, approximately 71% of those based in Western countries are related to infrastructure, while 67% of those based in Eastern countries are related to digital content and apps. The company ultimately aims to serve as a bridge connecting the East and West by acting as a network builder to facilitate this exchange, Kim said.
