Now you can buy cryptocurrency mining rigs in a Singapore shopping mall
The volatile and mysterious world of cryptocurrencies is now a shopping mall away – at least in Singapore.
Ready-made computing machines used to facilitate transactions in bitcoin and other digital currencies have appeared on the city state’s shop shelves even as its central bank sounds a note of caution.
The availability of store-bought “mining rigs”, each contributing its computing power to solve the complex mathematical problems needed to confirm transactions in digital currencies, means would-be cryptocurrency miners in the country no longer have to assemble their own machines out of separate components.
At Sim Lim Square, a popular shopping complex focused on electronics, at least five stores were selling cryptocurrency mining machines in recent weeks.
Shop owner Wilson Josup sells about 10 machines a week, up from one to two when he first started selling them about six months ago. Buyers range from those in their 20s to retirees, he said. The bulk of his customers use the S$4,000 (US$3,062) rig to mine Ethereum, the second largest cryptocurrency by market capitalisation.
“Most of my customers would ask me to help transfer the rigs from their homes to a data centre because they don’t like the heat and noise,” said Josup, adding that his profit margin on each rig was around 10 percent.
Based on customer testimonials, leaving a machine running constantly can net about S$400 a month, Josup said.
Still, the machines aren’t flying off the shelves for every shopkeeper.
Two floors down the same complex, cryptocurrency-mining rigs are on offer at a computer repair shop for S$5,500. Shop owner Trecia Tay hasn’t sold a single machine but says she gets some 10 queries about it a week, five times the rate three months ago.
In December, authorities in neighbouring Malaysia shut down two bitcoin-mining houses in the state of Selangor after neighbours complained of frequent power disruptions.
