Bitcoin miners are moving out of China as authorities intensify their crackdown, the heads of some of the world’s biggest cryptocurrency exchanges said.
“We’re seeing a lot of those miners moving out of China to other places,” Chao Changpeng (趙長鵬), chief executive officer of Binance Holdings Ltd (幣安控股), the world’s biggest cryptoexchange by reported turnover, said in an interview at the Qatar Economic Forum on Tuesday. “Some of them are sending their mining equipment to overseas. There’s big shipments.”
Chao said he has seen movement by clients in Binance’s mining pool, which combines the computing power of number-crunching machines that verify cryptocurrency transactions.

China’s moves have injected uncertainty into the cryptocurrency market and helped pull bitcoin down to the lower end of its recent trading range, with the coin briefly falling below US$30,000 on Tuesday, after having reached nearly US$65,000 in the middle of April.
The hashrate, which measures the processing power used in bitcoin mining and is used as a proxy for mining activity, has also dropped by about 40 percent in the past couple of weeks, data from BTC.com showed.
While a lower hashrate is often portrayed as a negative for bitcoin, a temporary disruption of mining power as rigs are moved out of China could also be embraced by some cryptocurrency bulls who argue that a concentration of mining capacity has long been a vulnerability for an asset prized by proponents for its independence from governments and central banks.
“In the future you’ll have a different geographical distribution of hashpower,” Sam Bankman-Fried, a former Jane Street trader who now runs the cryptoderivatives exchange FTX, said in an interview yesterday. “It’s expensive to move rigs, but it’s not impossible.”
China’s state-run Global Times reported that multiple bitcoin miners in China’s Sichuan Province were closed on Sunday as authorities intensified their crackdown.
On Tuesday, Bloomberg reported that China had summoned officials from its biggest banks to reiterate rules banning cryptocurrency services that were first issued in 2013.
China’s measures mean the nation’s share of bitcoin mining could fall from an estimated 65 percent to less than 50 percent by the end of the year, said Dan Weiskopf, a portfolio manager at the Amplify Transformational Data Sharing exchange traded fund, an actively managed fund that is composed of blockchain-related stocks, with about 20 percent of its portfolio in cryptominers.
Alternate destinations for Chinese mining operations include Russia, Kazakhstan and Texas, market participants said.
Weiskopf cited Canada, Sweden and Argentina as other possibilities.
“The decline in hash is probably a short-term phenomenon and evidence of China miners coming offline,” he said in an e-mail. “It is a net positive for North America miners who are now expanding and scheduled to have a lot of hash come online later in 2021 and into 2022.”
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
Singapore-based ride-hailing and delivery giant Grab Holdings Ltd has applied for regulatory approval to acquire the Taiwan operations of Germany-based Delivery Hero SE's Foodpanda in a deal valued at about US$600 million. Grab submitted the filing to the Fair Trade Commission on Friday last week, with the transaction subject to regulatory review and approval, the company said in a statement yesterday. Its independent governance structure would help foster a healthy and competitive market in Taiwan if the deal is approved, Grab said. Grab, which is listed on the NASDAQ, said in the filing that US-based Uber Technologies Inc holds about 13 percent of
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 —
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) yesterday received government approval to deploy its advanced 3-nanometer (3nm) process at its second fab currently under construction in Japan, the Ministry of Economic Affairs said in a news release. The ministry green-lit the plan for the facility in Kumamoto, which is scheduled to start installing equipment and come online in 2028 with a monthly production capacity of 15,000 12-inch wafers, the ministry said. The Department of Investment Review in June 2024 authorized a US$5.26 billion investment for the facility, slated to manufacture 6- to 12nm chips, significantly less advanced than 3nm process.
