Ah, cryptocurrency. The fun, volatile new wave of technology with a dark underbelly full of climate controversies and scams. According to Bukit Aman Criminal Investigation Department (CID) chief Datuk Seri Abd Jalil Hassan, crypto crimes like illegal bitcoin mining have increased drastically in 2021 compared to the previous year.

To be specific, Malaysia had 570 investigation papers opened, 528 people arrested and RM54 million worth of mining equipment seized in 2021 alone. In the previous year, there were only 20 papers opened, 26 people arrested and RM1.26 million worth of equipment seized. In terms of seized items, that’s more than a 4200% increase from 2020 to 2021.


The chief mentioned that the majority of offenders were between 18 to 30 years old, with the oldest suspect being 61 years old. Most of the crimes took place in Selangor, Kuala Lumpur, Perak and Penang as they have lots of industrial areas which can provide enough electricity for illegal mining. The suspects find business areas that are hidden so the public won’t hear the noise or feel the heat coming from the mining rigs. We’ve seen this happen in October with Sarawak Energy’s confiscation of over 1,200 mining rigs. Electricity theft has been booming in Malaysia, with a total of 7,209 cases being reported from 2018 to 2021.

Illegal mining is not the only crime that comes with cryptocurrency. Illicit activities involving ransomware and Ponzi schemes often use these digital currencies to hold astounding amounts of stolen money. In 2021, global crypto crime resulted in USD 14 billion (~RM58 billion) being stolen, which was up 79% from 2020’s USD 7.8 billion (~RM32 billion), reaching an all-time high.
