Cryptocurrencies plunged in Asia yesterday after a hack on South Korean exchange Coinrail sparked fresh concerns about the safety of the digital currencies.
The attack on Coinrail comes months after Japanese firm Coincheck said it had lost more than US$500 million in a hack in January.
Coinrail did not specify the value of the currency that was taken in the attack over the weekend, but said it was working with authorities and other coin developers to track down the culprits.
The firm, which trades more than 50 cryptocurrencies, added that it has frozen all exposed coins — Fundus X, Aston and Enper — and other units have been taken offline in a “cold wallet.”
The news sent cryptocurrencies tumbling, with bitcoin losing about 13 percent, ethereum down 12 percent and ripple almost 20 percent lower as traders fretted over the safety of their investments.
“This is ‘If it can happen to A, it can happen to B and it can happen to C,’ then people panic because someone is selling,” OANDA head of Asia-Pacific trade Stephen Innes said.
“The markets are so thinly traded, primarily by retail accounts, that these guys can get really scared out of positions,” Innes said. “It actually doesn’t take a lot of money to move the market significantly.”
Cryptocurrencies have plunged since the end last year, when bitcoin hit a record high near US$20,000, having surged from less than US$1,000 just 11 months earlier. The unit is now worth about US$6,780.
South Korea is one of the biggest markets for trading in digital currencies, but the boom in their popularity has forced the government to tighten regulations, following similar moves in other countries.
China has claimed a breakthrough in developing homegrown chipmaking equipment, an important step in overcoming US sanctions designed to thwart Beijing’s semiconductor goals. State-linked organizations are advised to use a new laser-based immersion lithography machine with a resolution of 65 nanometers or better, the Chinese Ministry of Industry and Information Technology (MIIT) said in an announcement this month. Although the note does not specify the supplier, the spec marks a significant step up from the previous most advanced indigenous equipment — developed by Shanghai Micro Electronics Equipment Group Co (SMEE, 上海微電子) — which stood at about 90 nanometers. MIIT’s claimed advances last

EUROPE ON HOLD: Among a flurry of announcements, Intel said it would postpone new factories in Germany and Poland, but remains committed to its US expansion Intel Corp chief executive officer Pat Gelsinger has landed Amazon.com Inc’s Amazon Web Services (AWS) as a customer for the company’s manufacturing business, potentially bringing work to new plants under construction in the US and boosting his efforts to turn around the embattled chipmaker. Intel and AWS are to coinvest in a custom semiconductor for artificial intelligence computing — what is known as a fabric chip — in a “multiyear, multibillion-dollar framework,” Intel said in a statement on Monday. The work would rely on Intel’s 18A process, an advanced chipmaking technology. Intel shares rose more than 8 percent in late trading after the
