Regulators clamp down on crypto energy as nations shift priorities

Policy & Regulation·November 25, 2025, 12:31 PM

The blockchain network underpinning Bitcoin, the world’s largest cryptocurrency, requires an energy volume comparable to the annual consumption of Thailand. According to Digiconomist’s Bitcoin Energy Consumption Index, the protocol utilized roughly 204.44 terawatt-hours (TWh) of electricity between Nov. 18, 2024, and Nov. 18, 2025.

Fiscal losses drive Malaysian oversight

Amid these intense energy demands, Malaysia’s primary electricity utility has recorded substantial financial impairments attributed to illicit activities. Tenaga Nasional Bhd (TNB) reported losses totaling 4.57 billion ringgit ($1.1 billion) from illegal crypto-mining operations over a five-year span. In a Nov. 19 report by The Edge Malaysia, the Ministry of Energy Transition and Water Transformation (Petra) disclosed these figures to parliament, specifying that the unauthorized mining occurred at 13,827 locations between 2020 and August of this year.

 

To counter these infractions through regulatory channels, Petra has formed a special committee scheduled to convene before year-end. This body aims to recommend enhancements to the Electricity Supply Act, which currently delineates penalties based on the offender's classification. Domestic violators face fines ranging from 1,000 to 50,000 ringgit ($240 to $12,000), imprisonment of up to one year, or both. Penalties escalate for non-domestic entities, involving fines between 20,000 and one million ringgit ($480 to $240,000) and potential prison terms of up to five years. Despite these provisions regarding electricity theft, a specific legal code regulating the act of crypto mining remains absent, creating a jurisdictional void.

 

International bans and grid reallocation

Strategies to curtail electricity usage by crypto miners are becoming evident elsewhere in Southeast Asia as well. Laotian Deputy Energy Minister Chanthaboun Soukaloun told Reuters last month that the nation intends to suspend electricity supplies to crypto miners by early 2026. He cited the sector's minimal economic contribution and low job creation as primary factors. Consequently, the state plans to redirect power to high-priority sectors, including AI data centers, metals processing, and electric-vehicle manufacturing.

 

Parallel restrictions are emerging globally. In October, the government of British Columbia enacted a permanent prohibition on new BC Hydro connections for crypto miners to safeguard the Canadian province’s energy reserves. Officials pointed to the industry’s "disproportionate energy consumption and limited economic benefit" as the rationale for the policy.

 

The debate over thermal innovation

Conversely, some enterprises are exploring methods to capture thermal output from Bitcoin mining to heat residential and commercial properties. If viable, such repurposing could utilize the considerable thermal byproducts of mining. A K33 Research study cited by CNBC indicates the industry generates roughly 100 TWh of heat annually, a figure sufficient to warm the entirety of Finland.

 

However, industry consensus on the feasibility of these applications remains elusive. Proponents suggest that mining infrastructure could be situated in proximity to heat consumers. Skeptics, however, contend that the reliance on application-specific integrated circuit (ASIC) chips makes this impractical, arguing that the technical difficulty of mining a block renders household participation unfeasible. Despite these differing views, the concept continues to attract attention as a potential avenue for innovation in energy distribution.

 

As jurisdictions like Malaysia and British Columbia tighten regulatory oversight, the cryptocurrency sector faces mounting pressure to address its energy footprint. The divergence between government restrictions and industry-led efficiency proposals underscores the complex relationship between digital asset infrastructure and global energy resources.

 

Given the shifting landscape of policy and technology, the outlook for sustainable large-scale crypto mining remains uncertain, as governments weigh energy demands against economic benefits and the industry searches for more efficient ways to operate.

Atomic Wallet Hacker Uses Lazarus Crypto Mixer

Atomic Wallet Hacker Uses Lazarus Crypto MixerThe stolen cryptocurrency from the recent $35 million hack of Atomic Wallet is already being moved to a crypto mixer favored by North Korea’s notorious cyber-hacking group.Photo by Micha Brändli on UnsplashSinbad.ioAccording to UK-based crypto compliance analysis firm Elliptic, the funds have made their way to a crypto mixer used by Lazarus Group, a notorious hacker group that focuses on crypto heists which is believed to have direct ties with the North Korean government.On June 5, Elliptic’s Investigations Team revealed that it had traced the funds from the Atomic Wallet hack to the crypto mixer Sinbad.io. Lazarus had previously used the mixer to launder over $100 million in stolen crypto assets.While the exact amount sent to the mixer was not specified, Elliptic noted that the stolen funds were being exchanged for Bitcoin before undergoing obfuscation through the mixer. Additionally, Elliptic reported that Sinbad.io is likely a rebranded version of Blender.io, another mixer extensively used to launder funds by the Lazarus Group. Blender.io has been sanctioned by the US Treasury.Atomic Wallet hackThe hack of several user accounts on Atomic Wallet occurred on June 3, resulting in losses of up to $35 million. News of the issue broke with the following tweet from the project team (which has subsequently been deleted): “We have received reports of wallets being compromised. We are doing all we can to investigate and analyze the situation. As we have more information, we will share it accordingly.”In a follow-up tweet the next day, the team confirmed that it was investigating the matter with the assistance of a number of “leading security companies.”However, Atomic Wallet later downplayed the incident, stating that less than 1% of its monthly active users were affected. The project team was castigated by users for trying to present the hack as a minor incident. One user took to Twitter to call out the Atomic Wallet team for “having the nerve to come to the networks and say that only 1% of wallets were affected.”The Atomic Wallet project is based out of Tallinn, Estonia, having been founded in 2017. It claims to provide a non-custodial decentralized multi-currency crypto wallet. The product supports over fifty coins and two hundred tokens. It also offers atomic swaps between digital assets, while also supporting integrations with instant exchanges such as Changelly, ShapeShift, and others.Roland Säde, the Chief Marketing Officer of Atomic Wallet, assured users that the team is working tirelessly to recover the stolen funds. He emphasized the need to complete the investigation to develop a concrete plan.Despite the ongoing efforts, Säde urged victims to track the illicit transfers and report them to popular crypto exchanges. By doing so, it was thought that may hinder the scammers from exchanging the funds.Crypto hacking menaceLazarus Group hackers have been the bane of the crypto space in recent years. Elliptic released a report last month that identified Japan as having been the country most adversely affected by the North Korean hackers. It’s understood that the estimated $721 million in stolen crypto from Japan-based entities amounts to nearly nine times the value of North Korea’s exports based on 2021 data.While Atomic Wallet is directly reporting the incidents, Säde believes that having more individuals monitoring the hackers’ activities will make it more challenging for them to move the funds undetected. Unfortunately, Elliptic’s recent findings suggest that for many victims, it may already be too late to prevent further misuse of their stolen cryptocurrency.

North Korea Using DeFi for Money Laundering

North Korea Using DeFi for Money LaunderingThe United States Treasury issued a warning on Thursday where it identifies North Korea as a user of DeFi services for money laundering. According to the Treasury, both North Korea and criminal organizations have been using DeFi platforms to launder dirty money.©Pexels/PixabayWhile DeFi has been praised for its potential to democratize finance and provide greater financial freedom to users, it has also been criticized for its lack of regulatory oversight. According to the Treasury, this lack of oversight has made DeFi platforms an attractive target for money launderers and other criminal organizations.In its warning, the Treasury noted that North Korea has been using DeFi platforms to launder money and evade international sanctions. The country is believed to have developed a sophisticated system for laundering money through cryptocurrency exchanges, and it is now turning its attention to DeFi platforms.Illicit money movementCriminal organizations are also using DeFi services for money laundering, according to the Treasury. These groups are said to be using DeFi platforms to move money around the world, in order to avoid detection and to launder the proceeds of their illicit activities.The use of DeFi for money laundering poses a significant challenge for law enforcement agencies, as these platforms operate outside of the traditional banking system and are often difficult to track. The Treasury has urged DeFi platforms to implement strong anti-money laundering (AML) and know-your-customer (KYC) policies, in order to prevent their services from being used for criminal activities.The warning from the Treasury comes at a time when DeFi is becoming increasingly popular among investors and users. According to data from DeFi Pulse, the total value locked in DeFi protocols recently surpassed $100 billion, indicating a significant level of interest and investment in the sector.Calls for greater regulationHowever, the lack of regulatory oversight and the potential for DeFi to be used for money laundering and other criminal activities have raised concerns among regulators and policymakers. Some have called for greater regulation of the sector, in order to prevent its abuse by criminal organizations.Despite these concerns, many proponents of DeFi argue that the sector has the potential to transform the financial industry and provide greater financial freedom to users. They point to the benefits of decentralized systems, such as greater transparency, lower fees, and faster transaction times.The use of DeFi for money laundering is a complex issue that requires a multifaceted approach. While regulators and policymakers must work to implement strong AML and KYC policies, users and investors must also take responsibility for ensuring that they are using DeFi platforms in a responsible and legal manner.Ultimately, the future of DeFi will depend on how the sector is able to balance innovation and regulation. While DeFi has the potential to transform the financial industry, it must also be subject to appropriate oversight and accountability in order to prevent its abuse by criminal organizations.By working together, regulators, policymakers, and industry stakeholders can help to ensure that DeFi is used for its intended purpose — to provide greater financial freedom and empowerment to users around the world.

China’s Jiangsu Province Integrates Digital Yuan Into Education System

China’s Jiangsu Province Integrates Digital Yuan Into Education SystemChina has taken a raft of measures to try to build momentum in its digital currency, the digital yuan or e-CNY, with the latest step being an expansion into the education system in Jiangsu Province.Photo by Kimberly Farmer on UnsplashChina’s digital yuan is a legal tender fully backed by the People’s Bank of China (PBOC) and pegged to the renminbi. Unlike most cryptocurrencies, it is not decentralized or anonymous but is monitored by the PBOC. While adoption has been slow, China has been first off the blocks in developing a central bank digital currency (CBDC) to the point of some level of active use by comparison with its international peers.Enforcing a payments use caseJiangsu Province will attempt to establish the use of the digital yuan in its education system by the end of 2025, according to the Jiangsu Education Department. By the end of the year, students studying within the province are likely to be paying tuition fees using the digital currency. The pilot plan that Jiangsu administrators within the province’s Education Department have put together also aims to establish a means through which examination registration fees will be paid in digital yuan, while scholarships will be received in the digital currency.Zhou Maohua, a researcher with Beijing-headquartered Everbright Bank, told China Daily that it is imperative that more users are registered and go on to actively use the digital yuan to further its development.“The establishment of infrastructure for the digital yuan should be further accelerated,” said Maohua. “Its software and hardware must be upgraded to improve user experience. The security and reliability of the system must also be strengthened,” he added.Over the course of the past three months, four million digital yuan accounts have been opened by ordinary citizens within Jiangsu Province. Total e-CNY transactions have reached a level in excess of 200 billion yuan ($29 billion).Multiple initiativesIn April, the administrators of the city of Changshu, which is situated within Jiangsu Province, announced that it was gearing up to commence paying state employees within the city in digital yuan. Around the same time, officials within the city of Xuzhou, also located within Jiangsu Province, announced that they were in the process of publishing a pilot scheme which will set out a means for promoting China’s e-CNY digital currency.If that was enough in proving Jiangsu’s commitment to furthering the development of the e-CNY, another Jiangsu Province city, Suzhou, was one of the first locations in China to run a digital yuan pilot scheme in April 2020.Earlier this month, it was revealed that the French international banking group, BNP Paribas, had partnered with the BOC in enabling an initiative to promote the use of the digital yuan among its corporate clients.China is working with other countries on a Multiple CBDC Bridge project to explore the feasibility of cross-border fund transfers among different currencies. Launching its own CBDC for cross-border transfers may allow China to reduce its reliance on the US dollar and increase its influence over global trade and monetary policy.
