Cryptocurrency miners, including HashCow and BTC.TOP, have halted their China operations after Beijing intensified a crackdown on bitcoin mining and trading, hammering digital currencies amid heightened global regulatory scrutiny of them.
A State Council committee led by Vice Premier Liu He announced the crackdown late on Friday as part of efforts to fend off financial risks. It was the first time the council has targeted virtual currency mining, a big business in China that accounts for as much as 70 per cent of the world's crypto supply.
Cryptocurrency exchange Huobi on Monday suspended both crypto-mining and trading services to mainland Chinese clients, adding it will instead focus on overseas businesses.
BTC.TOP, a crypto mining pool, also announced the suspension of its China business citing regulatory risks, while crypto miner HashCow said it would halt buying new bitcoin rigs.
Crypto miners use increasingly powerful, specially-designed computer equipment, or rigs, to verify virtual coin transactions in a process which produces newly minted crypto currencies such as bitcoin.
“Crypto mining consumes a lot of energy, which runs counter to China's carbon neutrality goals,” said Chen Jiahe, chief investment officer of Beijing-based family office Novem Arcae Technologies.
The crackdown is also part of China's stepped-up drive to curb speculative crypto trading, he added.
Bitcoin took a beating after the latest Chinese move, and is now down nearly 50pc from it's all-time high. It shed as much as 17pc on Sunday, before paring some losses and was last trading steady in Asia.
Elsewhere, Ether fell to a two-month low on Sunday, down 60pc from a record peak hit just 12 days ago,
Investor protection and money laundering are particular concerns of global financial regulators who are grappling with whether and how they should regulate the cryptocurrency industry.
The latest shakeout in digital currencies also stems from tighter scrutiny in the United States. Last Thursday, US Federal Reserve Chairman Jerome Powell said they pose risks to financial stability, and indicating that greater regulation of the increasingly popular electronic currency may be warranted.
Huobi made the announcement via its official Telegram community for Huobi Mall, as well in a statement to Reuters. BTC.TOP and HashCow could not be immediately reached for comment
