At a secret location in the middle of one of Iceland’s breathtaking lava fields stands a warehouse whose nondescript siding belies the fact it is ground zero in a digital gold rush for cryptocurrencies that is burning through more electricity than Icelanders’ homes.
Iceland’s combination of fire and ice not only makes it a stunning site to film parts of the medieval fantasy epic Game of Thrones, it also offers a unique combination of cheap renewable energy and free air-conditioning that is making it a promised land for those “mining” virtual currencies, including bitcoin, using powerful computers that are voracious users of electricity and throw off lots of heat.
And noise.

The din from shelves and shelves of computers whirring inside the 400m2 warehouse rivals a jet during takeoff.
Unlike the dollar and the euro, bitcoin is not issued by central banks.
Instead it is “mined” or created in computer “farms.” It uses computers souped up with six graphics cards tasked with the heavy lifting of thousands of thousands of calculations needed to solve complex algorithms to process bitcoin transactions and be rewarded with bitcoins in exchange.
“It’s possible for everyone to do it at home. There is no one stopping you [and] there are no technical limitations,” Genesis Mining Ltd head of operations Philip Salter said.
Last year saw a meteoric rise of hundreds of virtual currencies led by bitcoin, which was fetching almost US$20,000 per unit in December, as both amateur and professional miners jumped onto the cryptocurrency bandwagon.
Home miners often use an old computer, have no choice where they operate and are lucky if they get a fraction of a bitcoin every now and then.
Professionals like Genesis Mining need to invest serious amounts to build and equip a facility like this one with a surface area one-third of an Olympic swimming pool, but which has a much greater chance of catching part of the 12.5 bitcoins created every 10 minutes.
However, they can choose where to set up operations, and that choice can have a huge impact on their profit as the price of the electricity to power and cool the computers varies considerably from country to country.
Iceland is attractive for cryptocurrency mining because of its cheap electricity, which has the added advantage of being generated from clean geothermal energy.
At a 0.065 euros (US$0.08) per kilowatt-hour before tax, the cost of electricity in Iceland is nearly half the EU average.
This makes Iceland one of the most competitive nations in Europe after Serbia, Macedonia and Bosnia.
However, Iceland also has an advantage in that its average annual temperature is about 5°C, meaning mining farms can for most of the time just suck in cool air from the outside instead of running energy-hungry air-conditioners.
The power usage efficiency “is really good in Iceland because of the natural cooling,” said Johann Snorri Sigurbergsson, director of business development at Iceland’s power company HS Orka.
A growing number of firms like Genesis Mining, which was previously based in Bosnia, have chosen to set up shop in Iceland, which means demand for electricity has shot up.
“The demand has been increasing exponentially, especially the last three months,” Sigurbergsson said.
The increase has come as the price of bitcoin has plunged from its peak of nearly US$20,000 to less than US$9,000, with analysts saying that the price decline has made operating costs even more of a concern for miners.
Salter, who fears the growing competition in the sector, said bitcoin’s “price isn’t a very good indicator on how [the] bitcoin mining industry is doing.”
He might not have that much more competition from neighbors, as Sigurbergsson said HS Orka “will not be able to supply all the demand” from miners wanting to set up operations.
The utility is “in the great position of we can pick and choose who we can do business with,” he said.
HS Orka has estimated that Iceland’s three largest bitcoin farming companies this year will consume more electricity than the nation’s 350,000 inhabitants.
Miners also have another worry: Even a virtual gold rush attracts real thieves.
From December to January, equipment worth an estimated 1.6 million euros was stolen.
The domestic unit of the Chinese-owned, Dutch-headquartered chipmaker Nexperia BV will soon be able to produce semiconductors locally within China, according to two company sources. Nexperia is at the center of a global tug-of-war over critical semiconductor technology, with a Dutch court in February ordering a probe into alleged mismanagement at the company. The geopolitical tussle has disrupted supply chains, with some carmakers reportedly forced to cut production due to chip shortages. Local production would allow Nexperia’s domestic arm, Nexperia Semiconductors (China) Ltd (安世半導體中國), to bypass restrictions in place since October on the supply of silicon wafers — etched with tiny components to
Taiwan’s foreign exchange reserves fell below the US$600 billion mark at the end of last month, with the central bank reporting a total of US$596.89 billion — a decline of US$8.6 billion from February — ending a three-month streak of increases. The central bank attributed the drop to a combination of factors such as outflows by foreign institutional investors, currency fluctuations and its own market interventions. “The large-scale outflows disrupted the balance of supply and demand in the foreign exchange market, prompting the central bank to intervene repeatedly by selling US dollars to stabilize the local currency,” Department of Foreign
Taiwan is open to joining a global liquefied natural gas (LNG) program if one is created, but on the condition that countries provide delivery even in a scenario where there is a conflict with China, an energy department official said yesterday. While Taiwan’s priority is to have enough LNG at home, the nation is open to exploring potential strategic reserves in other countries such as Japan or South Korea, Energy Administration Deputy Director-General Chen Chung-hsien (陳崇憲) said. While the LNG market does not have a global reserve for emergencies like that of oil, the concept has been raised a few times —
AI-FUELED DEMAND: The company has been benefiting from the skyrocketing prices for DRAM chips amid the AI frenzy, especially its core product — DDR4 DRAM chips DRAM chipmaker Nanya Technology Corp (南亞科技) yesterday reported that its revenue for the first quarter surged 582.91 percent to NT$49.09 billion (US$1.54 billion) from NT$7.19 billion a year earlier, as the supply crunch caused chip price spikes. Last quarter’s figure is the highest on record. On a quarterly basis, revenue jumped 63.14 percent from NT$30.09 billion, the company said. In January, Nanya Technology expected global DRAM supply scarcity to continue through the first half of 2028, thanks to strong demand for artificial intelligence (AI) applications. Market researcher TrendForce Corp (集邦科技) forecast prices of standard DRAM chips would rise between 58 percent and 63
