BlackRock Investment Marks its Return to India

While many people assumed that Bitcoin hashrate had moved overseas once China implemented a Bitcoin mining ban in 2021, miners within mainland China still dominate the activity. 55% of hashrateThat’s according to a report on X by Ki Young Ju, the founder and CEO of crypto data analytics firm CryptoQuant. Taking to the social media platform on September 23, the CryptoQuant CEO claimed that Chinese mining pools account for 55% of all Bitcoin mining activity.  Since the 2021 ban, an increasing proportion of hashrate has been accounted for elsewhere, including the United States. Ju clarifies that U.S.-based mining pools now account for 40% of Bitcoin hashrate. He added:”U.S. pools primarily cater to institutional miners in America, while Chinese pools support relatively smaller miners in Asia.”Photo by Joshua Sortino on UnsplashShift towards U.S.-based miningWhile the majority of Bitcoin mining is accounted for within China’s borders, Ju acknowledges a growing shift towards U.S.-based mining. Some commentators have speculated that while officially a ban was put in place, in reality the ban presented an opportunity to jettison inefficient mining equipment, selling it on overseas, while maintaining only the most efficient miners within China. Others such as Daniel Batten, an advisor to Nasdaq-listed Bitcoin miner Marathon Digital, went further in suggesting that the reporting of a blanket ban on Bitcoin mining within China was misleading. Instead, he believes that mining was suspended for a time and then rebooted. Taking to X in June, Batten wrote: “Stop referring to it as a ban. It wasn't and it plays into [mainstream media] narratives of Bitcoin mining being unwelcome by nation states.” At the time, rather than Ju’s 55%, Batten estimated that 15% of overall hashrate was accounted for by Chinese miners. Profitability challengesIn the months following the halving of the Bitcoin mining reward, miners have been struggling to maintain profitability. Bitbo data indicates that miner revenue weighed in at $827.56 million in August, representing a 10.5% drop when compared with $927.35 million in July. The situation has raised questions about the ongoing sustainability of securing the Bitcoin network via the current mining model.  Yet despite these adverse conditions, miners have been maintaining the high hashrate level. JPMorgan analysts recently indicated that the Bitcoin hashrate has recovered to pre-halving levels. A report by Decrypt earlier this month claimed that some miners are aggressively purchasing new mining equipment while maintaining significant holdings of Bitcoin rather than selling it off. Alongside what was perceived to be a ban on Bitcoin mining in 2021, China prohibited the trading of cryptocurrencies. Notwithstanding that, it’s thought that many Chinese residents have access to crypto via bank accounts in Hong Kong, connected with global crypto exchanges. Hong Kong is perceived to be China’s sandbox for crypto with many speculating that the current pro-crypto stance taken within the Chinese autonomous territory had been approved by the authorities in mainland China. Whether China will lift its ban on crypto trading remains the subject of ongoing speculation. 

The local government of Busan, the second-largest city in South Korea, announced in a press release that it held the 3rd Busan Blockchain Regulation-free Zone Steering Committee (Committee) meeting at the Busan Eurasia Platform, a community center located near Busan Station.  The meeting took place last Thursday at 15:00 (KST), attended by 12 Committee members, including Busan’s Vice Mayor for Economic Affairs Kim Kwang-hee, Busan Technopark Chairman Kim Hyung-gyun, Busan International Finance Agency Chairman Lee Myung-ho and Busan Information Industry Promotion Agency Chairman Kim Tae-yeol.Photo by Finn on UnsplashThe meeting was intended to discuss strategies to revitalize the blockchain regulation-free zone (blockchain zone) and to attract new blockchain businesses to the region. Busan has been recently struggling with developing and attracting blockchain technology companies to the region, which has cast doubt on the city’s ability to retain its status as the regulatory sandbox zone.   New 24 members, new commitment to invigorating blockchain zone Established in October last year, the 3rd Committee comprises 24 new members who have expertise in blockchain technology. The Committee aims to raise awareness of the blockchain zone’s potential and foster the blockchain industry within the region.  Kim Sang-min, Vice CEO of healthcare company Erom, was appointed Committee Chairman at the meeting. Known as an expert in the blockchain ecosystem, Kim currently serves as a blockchain policy advisor for Busan and has experience in taking the lead in establishing the Busan Digital Asset Exchange (BDX) last year.  More meetings in store to become a blockchain hub The meeting focused on creating subcommittees in an effort to facilitate the Committee’s seamless operation. Moreover, members reached a consensus on holding meetings at any time when warranted, in both online and in-person formats.  During the meeting, Busan Vice Mayor Kim said the newly launched Committee will contribute to identifying innovative businesses with great potential that require both cutting-edge blockchain technologies and a regulatory sandbox environment. 

South Korea’s ruling Democratic Party has set up a new task force to accelerate the creation of a clear regulatory framework for stablecoins, aiming to unify competing legislative proposals ahead of government guidelines expected in October. According to Etoday, the nine-member group, chaired by Representative Lee Jung-moon of the National Policy Committee, is composed of lawmakers from three key parliamentary committees. Its primary objective is to consolidate the party's position on digital asset policy and coordinate with the Financial Services Commission (FSC) to establish a definitive rulebook for the burgeoning sector. Lee stated that the task force would work to harmonize multiple stablecoin bills already circulating within the party, noting that there was mounting pressure from both regulators and the private sector. He explained that government agencies had urged swift legislative action, while financial institutions and exchanges preparing to launch won-pegged stablecoins were waiting for regulatory certainty.Photo by SC Jang on UnsplashRegulatory debate over capital standardsA central point of contention for the task force will be establishing appropriate capital requirements for stablecoin issuers. Current proposals vary in scope, with suggested thresholds ranging from 500 million won (approximately $358,000), a figure intended to encourage fintech innovation, to as high as 5 billion won (about $3.58 million) to prioritize investor protection. The committee is tasked with striking a balance between fostering market growth and ensuring financial stability. Seoul's initiative reflects a broader global movement toward formal oversight of fiat-backed digital currencies. The U.S. passed its GENIUS Act for stablecoins in July, while the EU has implemented its Markets in Crypto-Assets (MiCA) regulation. Similarly, Japan amended its Payment Services Act in 2023 to restrict stablecoin issuance to licensed banks and registered financial firms. Former White House crypto advisor’s inputThe push for clear rules has drawn keen interest from industry leaders. Speaking at Korea Blockchain Week 2025 in Seoul, Bo Hines, chief executive of Tether USAT, stressed the regulatory clarity provided by the GENIUS Act in the U.S. According to ZDnet Korea, he noted that his company's new dollar-backed token, USAT, is designed for full compliance with U.S. law, featuring one-to-one reserves and audits by top-tier accounting firms to attract institutional investors. Hines, a former digital assets adviser at the White House, clarified that USAT is intended to serve the regulated U.S. market, complementing Tether’s flagship product, USDT, which has a global user base exceeding 500 million. He also discussed Tether’s view of South Korea as a key market, pointing to the significant USDT trading volumes there. Hines encouraged the country to adopt comparable stablecoin standards and expressed optimism that it would move toward a more open and efficient global financial network. With the FSC’s guidance approaching, the Democratic Party’s task force is working to reconcile differing legislative proposals. The resulting framework will shape the pace at which stablecoins move from pilot projects to an established part of South Korea’s financial system.
