Malaysian authorities have stepped up a nationwide crackdown on illegal cryptocurrency mining, confiscating more than 75,000 devices in more than 3,000 raids since 2022. Deputy Home Minister Datuk Seri Dr Shamsul Anuar announced in Malaysia’s Dewan Rakyat that 629 people were arrested during the same period, highlighting the widespread nature of the irregularities.
How authorities are tackling power theft in mines
The joint effort involves the Royal Malaysian Police, state-owned power company Tenaga Nasional Berhad (TNB) and local authorities, and specifically targets illegal activities such as electricity theft and electricity meter tampering. These raids are aimed at disrupting operations to tamper with electricity meters, draw illegal power supplies, and install unauthorized equipment. TNB, the main electricity supplier, plays a key role in these interventions by pinpointing hotspots of illegal energy consumption.
Dr. Shamsul Anuar highlighted the expansion of intelligence and technology-driven audits to proactively combat high-risk mining areas.
As Anuar pointed out, the growing demand for digital assets and the lure of profits from price fluctuations are fueling illegal mining activities. Despite financial temptations, he reiterated that illegal electricity use is indefensible.
Is cryptocurrency trading legal without abusing power?
In Malaysia, trading and ownership of virtual currencies is allowed, but they do not have the status of legal tender. Problems arise when miners choose to circumvent legal routes and make unauthorized power settings, meter changes, or operate without proper licenses. Financial supervision over digital markets will fall under the Securities Commission, with Bank Negara Malaysia ensuring regulatory compliance across the financial system.
“Profit cannot justify infrastructure tampering or energy theft,” Anuar said.
What does the recent number of seizures reveal?
This trend has continued for several years, and the effort has recovered significant losses, with the Department of Energy reporting that more than 14,000 clandestine mines will drain approximately $1.1 billion in electricity by 2025. Strategic collaboration between key government agencies such as the Ministry of Finance and TNB is aimed at limiting these fiscal impacts.
Bold enforcement tactics include physically destroying seized machinery to deter future violations, and this practice is displayed in key public places. Similar anti-mine operations are gaining momentum in other parts of Asia, including Thailand and Hong Kong.
- Since 2022, more than 3,000 surgeries have been performed across the country.
- Over 75,000 cryptocurrency mining devices were seized.
- 629 people were detained in connection with illegal mining activities.
- Approximately $1.1 billion in power losses were reported.
- 14,000 illegal mining sites identified across Malaysia.
Malaysia continues to strengthen its enforcement strategy against illegal cryptocurrency mining, demonstrating the country’s firm determination to maintain the legal use of energy resources while developing its digital currency environment. A concerted effort is essential to maintain the integrity and financial stability of the region’s power infrastructure.
