Bitcoin price fell more than 11 percent after South Korea yesterday said it would ban anonymous trading of virtual currencies and crack down on money laundering activities using them.
The announcement came as the hyper-wired South Korea emerged as a hotbed for cryptocurrency trading, accounting for about 20 percent of global bitcoin transactions — about 10 times the country’s share of the world economy.
The new rules announced by Seoul include a ban on opening anonymous cryptocurrency accounts and new legislation to allow regulators to close virtual currency exchanges if necessary.
“Officials share the view that virtual currency trading is overheating irrationally ... and we can no longer overlook this abnormal speculative situation,” the government said in a statement.
Anonymous accounts in use are to be closed next month, it added.
The policy package includes stepping up crackdowns on money laundering activities and financial fraud — including price manipulation — using digital currency trades.
“We will ... resolutely respond to such crimes by slapping the maximum sentences possible on offenders,” it said, vowing to “leave all policy options open, including closure of a cryptocurrency exchange when deemed necessary.”
The announcement came two weeks after Seoul banned financial firms from dealing in virtual currencies — most notably bitcoin — as their prices soared, sparking concerns of a bubble largely fueled by retail speculators.
The digital unit hit a record of about US$19,500 earlier this month, meaning it had increased more than 25-fold from its low in the middle of January.
About 1 million South Koreans, many of them small-time investors, are estimated to own bitcoin. Demand is so high that prices for the unit are about 20 percent higher than in the US, its biggest market.
Seoul yesterday warned that most cryptocurrencies are being traded in the country at prices far higher than elsewhere in the world, blaming factors including “blind speculation.”
The price of bitcoin fell 11.6 percent to US$13,827 after yesterday’s announcement.
In a case highlighting the risks of cryptocurrency, a Seoul virtual currency exchange last week declared itself bankrupt after being hacked for the second time this year.
The Youbit exchange became the first South Korean cryptocurrency exchange to close after a hacking attack that stole 17 percent of its assets.
There have been numerous warnings about a possible blowout in the bitcoin market.
Bank of Japan Governor Haruhiko Kuroda last week said the price surge of the virtual currency was “abnormal.”
Meanwhile, the Monetary Authority of Singapore, the city-state’s central bank, has advised investors to “act with extreme caution.”
European Central Bank Vice President Vitor Constancio has also expressed concern about the relentless rise in the value of bitcoin and the potential risk accompanying the trend.
COMPETITION: AMD, Intel and Qualcomm are unveiling new laptop and desktop parts in Las Vegas, arguing their technologies provide the best performance for AI workloads Advanced Micro Devices Inc (AMD), the second-biggest maker of computer processors, said its chips are to be used by Dell Technologies Inc for the first time in PCs sold to businesses. The chipmaker unveiled new processors it says would make AMD-based PCs the best at running artificial intelligence (AI) software. Dell has decided to use the chips in some of its computers aimed at business customers, AMD executives said at CES in Las Vegas on Monday. Dell’s embrace of AMD for corporate PCs — it already uses the chipmaker for consumer devices — is another blow for Intel Corp as the company
ADVANCED: Previously, Taiwanese chip companies were restricted from building overseas fabs with technology less than two generations behind domestic factories Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), a major chip supplier to Nvidia Corp, would no longer be restricted from investing in next-generation 2-nanometer chip production in the US, the Ministry of Economic Affairs said yesterday. However, the ministry added that the world’s biggest contract chipmaker would not be making any reckless decisions, given the weight of its up to US$30 billion investment. To safeguard Taiwan’s chip technology advantages, the government has barred local chipmakers from making chips using more advanced technologies at their overseas factories, in China particularly. Chipmakers were previously only allowed to produce chips using less advanced technologies, specifically
MediaTek Inc (聯發科) yesterday said it is teaming up with Nvidia Corp to develop a new chip for artificial intelligence (AI) supercomputers that uses architecture licensed from Arm Holdings PLC. The new product is targeting AI researchers, data scientists and students rather than the mass PC market, the company said. The announcement comes as MediaTek makes efforts to add AI capabilities to its Dimensity chips for smartphones and tablets, Genio family for the Internet of Things devices, Pentonic series of smart TVs, Kompanio line of Arm-based Chromebooks, along with the Dimensity auto platform for vehicles.

BRAVE NEW WORLD: Nvidia believes that AI would fuel a new industrial revolution and would ‘do whatever we can’ to guide US AI policy, CEO Jensen Huang said Nvidia Corp cofounder and chief executive officer Jensen Huang (黃仁勳) on Tuesday said he is ready to meet US president-elect Donald Trump and offer his help to the incoming administration. “I’d be delighted to go see him and congratulate him, and do whatever we can to make this administration succeed,” Huang said in an interview with Bloomberg Television, adding that he has not been invited to visit Trump’s home base at Mar-a-Lago in Florida yet. As head of the world’s most valuable chipmaker, Huang has an opportunity to help steer the administration’s artificial intelligence (AI) policy at a moment of rapid change.
