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.

Hong Kong Authorities Unite to Form Crypto-Centric Taskforce

Hong Kong Authorities Unite to Form Crypto-Centric TaskforceAuthorities in Hong Kong are taking action to address recent mounting concerns surrounding illicit cryptocurrency activities, particularly in light of the recent JPEX scandal. The Hong Kong Police Force and the Securities and Futures Commission (SFC) have come together to establish a specialized working group dedicated to closely monitoring and countering suspicious activities connected to virtual asset trading platforms (VATPs).In a statement published by Hong Kong’s Securities and Futures Commission (SFC) on Wednesday (local time), the agency set out details of a collaborative task force which has been formed in the wake of a high-level meeting held on September 28.The collaboration draws on input from the SFC as well as a number of law enforcement divisions within the Chinese autonomous territory, including the Commercial Crime Bureau, Cyber Security and Technology Crime Bureau, and Financial Intelligence and Investigations Bureau.Photo by Cheung Yin on UnsplashGreater coordination and information sharingThe primary objectives of this alliance are to enhance coordination, foster information sharing, assess risks tied to VATPs, and, above all, safeguard the interests of the Hong Kong public.Christopher Wilson, Director of Enforcement at the SFC, underscored the regulator’s commitment to allocating resources to combat problematic VATPs and safeguard investor interests. Eve Chung, Assistant Commissioner of Police (Crime) at the Hong Kong Police Force, emphasized the significance of intelligence exchange and collaborative efforts in responding to the challenges posed by VATPs to protect the Hong Kong public.Knee jerk response to JPEX scandalIt would appear that the necessity for such a concerted effort became patently clear as a direct response to the errant activities of Dubai-based crypto platform JPEX within Hong Kong.Issues with the exchange first emerged in September when the platform outlined that it was having liquidity issues as a consequence of some third party market makers having withdrawn their services. JPEX subsequently raised withdrawal fees to an unreasonable level to deter customers from withdrawing funds from the platform.The saga has affected over 1,600 investors with more than $150 million in assets becoming unavailable to them. The case resulted in the arrest of at least 20 individuals, with local telecom providers blocking online access to the platform as requested by law enforcement.Earlier, on September 13, the SFC had issued a warning accusing JPEX and crypto influencers of disseminating false or misleading information on social media about their application for a virtual asset trading license in Hong Kong.The ongoing JPEX controversy has prompted regulators in Hong Kong to explore measures to strengthen regulations governing the cryptocurrency market. The establishment of the task force signifies a proactive stance to address these concerns and ensure swift, effective action against illicit activities in the crypto sector.In addition to the joint task force, the SFC has taken steps to enhance transparency by publishing a comprehensive list that includes licensed, deemed licensed, closing down, and application-pending crypto exchanges, along with a list of “suspicious VATPs.” This transparency initiative aims to provide clarity and protect investors by offering insights into legitimate and questionable cryptocurrency trading platforms operating in Hong Kong.

Pakistan appoints crypto advisor to PM & allocates 2K MW to Bitcoin mining

Recent weeks have seen a positive policy shift in Pakistan with regard to digital assets and blockchain and that initiative has gathered further momentum with the appointment of a special assistant on blockchain and crypto to the Pakistani prime minister and the allocation of 2,000 MW of surplus electricity to Bitcoin mining and AI data centers.Photo by Abuzar Xheikh on UnsplashOn May 26, the Pakistan Observer, an English language daily newspaper, reported that Bilal bin Saqib has been appointed to serve as a special assistant on blockchain and crypto matters to Pakistani Prime Minister Shehbaz Sharif. Forbes ‘30 under 30’ social entrepreneurIn this role, Saqib assumes the status of a minister of state under Rule 4(6) of the Rules of Business, 1973, with the appointment effective immediately. Saqib had been featured by Forbes through its “30 under 30” list of social entrepreneurs in Asia in 2020. He is the founder of Tayaba.org, a non-governmental organization (NGO) focused on the provision of clean drinking water to vulnerable communities in Pakistan. Saqib came to prominence in the crypto sector earlier this year when he was appointed CEO of the newly formed Pakistan Crypto Council (PCC), an agency established to promote blockchain technology and digital assets within the South Asian country. In April he was added by World Liberty Financial, a crypto project connected with the family of U.S. President Donald Trump, as an advisor. Earlier this month, Pakistan’s Ministry of Finance gave the go-ahead for the establishment of the Pakistan Digital Assets Authority (PDAA), a body that will be responsible for the implementation of regulations governing the crypto and blockchain sector.  Utilizing surplus energyAt the time, one area of focus that had been highlighted in the announcement of the establishment of the PDAA was a desire to make better use of Pakistan’s surplus energy. The country runs an annual average surplus of 4,000 megawatts. A report by 24 Digital on May 25 indicated that action has already been taken in this regard. It outlined that Pakistan has allocated 2,000 megawatts of surplus electricity for the exclusive use of operators of AI data centers and Bitcoin mining facilities.  This plan is being rolled out in phases. The first phase makes surplus energy available to these operators. Phase 2 will focus on enabling crypto mining operators to avail of renewable energy to power their facilities, in an effort to develop the sector in Pakistan in an environmentally responsible manner. According to the Ministry of Finance, interest has already been expressed by international operators in the crypto mining and AI data center sectors. A number of international firms are understood to have visited the country in an effort to explore potential collaboration opportunities.  Earlier this month, Saqib claimed on social media that Pakistan “is moving at crypto speed.” He made the case that the country is a breeding ground for crypto innovation, citing the opportunity to exploit surplus electricity via crypto mining and the potential for crypto adoption given a $36 billion remittance market, millions of unbanked citizens and 64% of the population under 30.
