Hong Kong Police Crack Down on Illegal Crypto Mining in Care Homes
In a shocking case that highlights the growing issue of illicit cryptocurrency mining, Hong Kong police have arrested two men for siphoning electricity from care homes for the disabled to run cryptocurrency mining rigs. The case underscores both the ethical and financial impact of illegal cryptocurrency operations, as well as the vulnerability of unsuspecting organizations.
The Setup: Mining Rigs Hidden in Ceilings
According to law enforcement, the two suspects, aged 32 and 33, utilized their access to care facilities during renovation projects to install eight crypto mining machines covertly. These rigs were hidden within suspended ceilings in the offices of two care homes, running around the clock and consuming vast amounts of energy. Monthly electricity bills surged by an estimated $1,153 (HK$9,000), drawing attention to the anomaly.
The case came to light after IT staff at one of the care homes noticed a significant slowdown in internet services. Upon investigation, unauthorized equipment was discovered concealed above the office ceiling. Similar devices were later uncovered in another care home in the Sau Mau Ping district, prompting further action by authorities.
The Cost of Illegal Crypto Mining
Inspector Ng Tsz-wing from the technology and financial crime squad emphasized the safety risks and financial toll of illegal crypto mining. Under Hong Kong’s Theft Ordinance, “abstracting electricity” is classified as a serious crime, carrying a maximum prison sentence of five years. Inspector Ng urged organizations to monitor contractors during renovations and to watch for sudden spikes in electricity bills or internet usage.
Crypto mining operations, even on a small scale, consume considerable energy. Indeed, cryptocurrency mining involves the use of specialized computers to solve complex mathematical problems. This process consumes massive amounts of electricity in exchange for digital coins—often leaving unsuspecting victims footing the bill.
A Growing Global Concern
The Hong Kong incident is not an outlier. Illegal cryptocurrency mining has been reported globally as miners attempt to cut costs by stealing electricity. In Thailand, police raided three abandoned houses used to host 63 mining machines connected illegally to utility poles. Similarly, cases in the UK and Central Asia have revealed widespread abuse of energy resources. For example, Tajikistan reported an estimated $3.5 million in stolen electricity due to crypto mining in just the first half of 2025.
The Carbon Footprint of Crypto Mining
Beyond the legal and financial implications, cryptocurrency mining contributes significantly to environmental concerns. According to Digiconomist, Bitcoin mining generates an annual carbon footprint of over 105 million tons of CO2—comparable to the total annual emissions of Belgium. Additionally, Bitcoin’s electricity consumption rivals that of Thailand, while its freshwater demand mirrors that of Switzerland. This raises ethical questions regarding the sustainability of these practices, especially when conducted illegally.
Protecting Against Crypto Mining Abuse
Cryptocurrency mining expert Shanon Squires, Chief Mining Officer at Compass Mining, emphasizes that illegal mining constitutes both “power theft and a safety risk.” He notes that unauthorized operations clash with the principles of Bitcoin and other cryptocurrencies, which prioritize private property rights and harm reduction.
Organizations are advised to remain vigilant, particularly during renovations. Regular monitoring of electricity usage, sudden spikes in utility bills, and unexpected drops in internet performance can offer early warning signs of illicit activities. Reporting suspicious instances to local authorities is crucial to curbing this damaging practice.
