$46bn Bitcoin sell-off follows South Korean crypto exchange hack attack



A cryptocurrency exchange hack in South Korea jolted holders of digital assets, fuelling a $46 billion sell-off and extending this year’s Bitcoin slump to more than 50 per cent.

The hack brought an abrupt end to two weeks of calm for the biggest virtual currency and reignited concerns about the security of lightly regulated crypto exchanges. The venues have come under growing scrutiny in South Korea, the US and other large economies in recent months amid a range of issues including thefts, market manipulation and money laundering.

Bitcoin has dropped 11 per cent since 5pm New York time on Friday and was trading at $6,781.19 as of 11:43am in Hong Kong on Monday, bringing its year-to-date loss to 53 per cent. Most other major virtual currencies also slumped, sending the market value of digital assets tracked by Coinmarketcap.com to a nearly two-month low of $294bn. At the height of the global crypto-mania in early January, they were worth about $830bn.

Enthusiasm for virtual currencies has waned partly due to a string of cyber heists, including the nearly $500 million theft from Japanese exchange Coincheck in late January. While the latest hacking target - a South Korean venue called Coinrail - is much smaller, the news triggered knee-jerk selling by investors, according to Stephen Innes, head of Asia Pacific trading at Oanda in Singapore.

“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,” Mr Innes said.

The slump may have been exacerbated by low market liquidity during the weekend, he added.

“The markets are so thinly traded, primarily by retail accounts, that these guys can get really scared out of positions,” he said. “It actually doesn’t take a lot of money to move the market significantly.”

Coinrail said in a statement on its website that some of the exchange’s digital currency appears to have been stolen by hackers, but it didn’t disclose how much. The venue added that 70 per cent of the cryptocurrencies it holds are being kept safely in a cold wallet, which isn’t connected to the internet and is less vulnerable to theft. Two-thirds of the stolen assets - which the exchange identified as NPXS, NPER and ATX coins - have been frozen or collected, while the remaining one third is being examined by investigators, other exchanges and cryptocurrency development companies, it said.

Coinrail trades more than 50 different cryptocurrencies and was among the world’s Top 100 most active venues, with a 24-hour volume of about $2.65 million, according to data compiled by Coinmarketcap.com before news of the hack.

The Korean National Police Agency didn’t immediately reply to a request for comment.

Some Asia-listed stocks with exposure to digital currencies fell on Monday. South Korea’s Omnitel and Vidente both retreated at least 3.9 per cent, while Japan’s Remixpoint slumped about 5 per cent.

Some of Darwish's last words

"They see their tomorrows slipping out of their reach. And though it seems to them that everything outside this reality is heaven, yet they do not want to go to that heaven. They stay, because they are afflicted with hope." - Mahmoud Darwish, to attendees of the Palestine Festival of Literature, 2008

His life in brief: Born in a village near Galilee, he lived in exile for most of his life and started writing poetry after high school. He was arrested several times by Israel for what were deemed to be inciteful poems. Most of his work focused on the love and yearning for his homeland, and he was regarded the Palestinian poet of resistance. Over the course of his life, he published more than 30 poetry collections and books of prose, with his work translated into more than 20 languages. Many of his poems were set to music by Arab composers, most significantly Marcel Khalife. Darwish died on August 9, 2008 after undergoing heart surgery in the United States. He was later buried in Ramallah where a shrine was erected in his honour.

What is graphene?

Graphene is extracted from graphite and is made up of pure carbon.

It is 200 times more resistant than steel and five times lighter than aluminum.

It conducts electricity better than any other material at room temperature.

It is thought that graphene could boost the useful life of batteries by 10 per cent.

Graphene can also detect cancer cells in the early stages of the disease.

The material was first discovered when Andre Geim and Konstantin Novoselov were 'playing' with graphite at the University of Manchester in 2004.

The Melbourne Mercer Global Pension Index

The Melbourne Mercer Global Pension Index

Mazen Abukhater, principal and actuary at global consultancy Mercer, Middle East, says the company’s Melbourne Mercer Global Pension Index - which benchmarks 34 pension schemes across the globe to assess their adequacy, sustainability and integrity - included Saudi Arabia for the first time this year to offer a glimpse into the region.

The index highlighted fundamental issues for all 34 countries, such as a rapid ageing population and a low growth / low interest environment putting pressure on expected returns. It also highlighted the increasing popularity around the world of defined contribution schemes.

“Average life expectancy has been increasing by about three years every 10 years. Someone born in 1947 is expected to live until 85 whereas someone born in 2007 is expected to live to 103,” Mr Abukhater told the Mena Pensions Conference.

“Are our systems equipped to handle these kind of life expectancies in the future? If so many people retire at 60, they are going to be in retirement for 43 years – so we need to adapt our retirement age to our changing life expectancy.”

Saudi Arabia came in the middle of Mercer’s ranking with a score of 58.9. The report said the country's index could be raised by improving the minimum level of support for the poorest aged individuals and increasing the labour force participation rate at older ages as life expectancies rise.

Mr Abukhater said the challenges of an ageing population, increased life expectancy and some individuals relying solely on their government for financial support in their retirement years will put the system under strain.

“To relieve that pressure, governments need to consider whether it is time to switch to a defined contribution scheme so that individuals can supplement their own future with the help of government support,” he said.
