Iran caps stablecoin transactions amid currency devaluation and sanctions

Leading crypto exchange platform OKX has disclosed plans to discontinue its mining pool services, marking a strategic shift for the platform.Photo by engin akyurt on UnsplashService shutdown within one monthThe move, outlined by the firm in a notification to platform users on Friday, involves ceasing new user registrations effective immediately. Existing users will be granted access to the mining pool until Feb. 25. All mining pool-related services on OKX will be completely halted by Feb. 26. Mining Pools data reveals that OKX holds the 36th position among the top 70 bitcoin-focused mining pools, boasting a total hash rate slightly exceeding 496 TH/s. The decision to phase out mining pool services was attributed to "business adjustments," as communicated by OKX, though further details were not provided regarding the specific nature of these adjustments. Previously, OKX's mining pool supported various proof-of-work cryptocurrencies and offered staking services. However, over recent years, many supported assets had been terminated. Presently, the website only displays bitcoin, litecoin and ethereum classic pool services. Once accounted for 5% of all BTC blocks minedOKX's bitcoin mining pool had once accounted for around 5% of the blocks mined on the network. However, a setback occurred on October 16, 2020, when the crypto exchange temporarily suspended withdrawals due to one of its private key holders “cooperating with a public security bureau in investigations.” This led to a significant drop in hashpower connected to the pool, from 9,000 PH/s to 20 PH/s. The pool's current 528 TH/s now represents less than 0.0001% of bitcoin’s total hash rate. Industry trend formingThis strategic move by OKX reflects the evolving landscape of the crypto industry and the challenges faced by mining pools, particularly in the context of regulatory and operational adjustments within the market. The decision may even amount to a formative trend, given that global crypto exchange platform rival KuCoin made a similar move back in August. At the time, KuCoin outlined its plans to temporarily suspend its bitcoin and litecoin mining pools. Although it suggested a temporary halt to such services, there was no indication of when such mining-related services would resume. A company spokesperson stated:“We will see if it is needed to restart based on the market and users’ demand in the future.” Bitcoin halving pressuresOKX’s decision to discontinue mining pool services comes ahead of bitcoin's anticipated fourth halving in April, which is expected to reduce miner rewards from 6.25 to 3.125 BTC. The halving is casting a shadow over the mining sector. Miners' business cost per bitcoin mined is going to increase significantly. Some industry commentators speculate that the break-even point for miners will reach an unsustainable level. NASDAQ-listed Riot Blockchain, in particular, is being singled out as potentially being susceptible due to its cost structure. Miners have had a difficult couple of years, working their way through the bear market component of the last market cycle. That period saw leading miner Core Scientific declare bankruptcy. The company has since restructured and has been relisted on the NASDAQ.  

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.Photo by Fré Sonneveld on UnsplashFiscal losses drive Malaysian oversightAmid 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 reallocationStrategies 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 innovationConversely, 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.

The South Korean government and the Democratic Party of Korea (DPK) plan to finalize legislation governing Korean won–pegged stablecoins by March. According to local media outlet DataNews, the two sides will hold a closed-door meeting on Jan. 20 to discuss agenda items related to the proposed Digital Asset Basic Act, widely referred to as the second phase of South Korea’s cryptocurrency legislation. A key sticking point is who should be allowed to issue stablecoins. Financial regulators favor, at least initially, limiting issuance to consortia in which banks hold a majority stake (50% plus one share), citing concerns about financial-market stability. The Democratic Party, however, opposes granting banks majority control. Separately, the draft would require issuers to meet capital-adequacy standards and maintain reserves equal to at least 100% of outstanding stablecoins.Photo by Greg Willson on UnsplashCBDC pilots to streamline public fundsBeyond private stablecoins, the government is also exploring potential public-sector uses for central bank digital currencies (CBDCs), including pilot programs that would deploy CBDC-based deposit tokens. As part of a broader digital transformation push, officials aim to use CBDC rails for a significant portion of public funds administration. By June, CBDC-based deposit tokens are set to be used in an electric vehicle charging infrastructure project: buyers of approved chargers would receive tokens to help ensure subsidies go only to eligible purchases and to shorten settlement times. Regulators are also considering steps to expand institutional access to cryptocurrencies. Under one proposal, publicly listed companies would be allowed to invest up to 5% of their equity in digital assets annually. Eligible investments would be limited to the top 20 tokens traded on the country’s five largest exchanges, with the list reviewed every six months. It remains undecided whether stablecoins, including USDT, would be included. Another planned change would permit the trading of exchange-traded funds (ETFs) that track spot crypto prices. While current law does not recognize digital assets as eligible underlying assets for such products, that is expected to change under the forthcoming legislative revision. Exchanges say caps threaten growthAt the same time, proposed governance changes that could cap controlling stakes at around 15% to 20% have drawn pushback from industry groups. The draft Digital Asset Basic Act would reshape control structures at South Korea’s largest cryptocurrency exchanges—Upbit, Bithumb, Coinone, and Korbit—which together serve roughly 11 million users. Regulators at the Financial Services Commission (FSC) say the measures are intended to curb concentrated influence by founders and major shareholders, and are considering a framework modeled on rules for alternative trading systems (ATS) under the Capital Markets Act. Yonhap News reported that the Digital Asset eXchange Alliance (DAXA)—which includes the four exchanges above as well as Gopax—has warned the proposed governance restrictions could slow the growth of South Korea’s crypto industry. The group argued the changes would dilute the accountability of a clear controlling shareholder, particularly regarding custody and management of customers’ digital assets. DAXA urged regulators to adopt a framework aligned with global standards, warning that stricter caps could increase uncertainty for startups and discourage entrepreneurship and investment. Investors pour $2.4B into overseas crypto ETFsThe lack of domestically available spot crypto ETFs has also driven Korean investors to seek exposure overseas. According to the Korea Securities Depository, as cited by Edaily, Korean investors bought a net $2.37 billion of foreign crypto ETFs between Jan. 13, 2025, and Jan. 12, 2026, placing these products among the top 50 overseas securities by net purchases over the period. Those purchases included a mix of spot-linked products, crypto futures–based instruments, and funds tracking companies that hold digital assets on their balance sheets. Several of the most heavily purchased products involved leverage or options-based strategies, including the T-REX 2x Long BMNR Daily Target ETF ($573.1 million) and the YieldMax MSTR Option Income ETF ($493.9 million). Leverage-heavy demand has been a recurring feature of Korean retail trading. In an October report, Bloomberg noted that prospective homebuyers have increasingly turned to crypto in hopes of building capital, fueling appetite for higher-risk altcoins. Such tokens account for more than 80% of trading volume on local exchanges.
