GUANGZHOU, China — Huobi, one of the world’s largest cryptocurrency exchanges, said it has ceased new account openings for mainland Chinese users after Beijing renewed a crackdown on virtual currencies.
Huobi, one of these exchanges, said on Sunday that it would end account registrations for new mainland Chinese users. The company will also gradually retire existing accounts of mainland Chinese users by midnight on Dec. 31, 2021.
Meanwhile Binance, one of the world’s largest cryptocurrency exchanges, said that account registrations using Chinese mobile phone numbers are now blocked. The Binance app is also no longer available for download in China.
“Binance takes its compliance obligations very seriously and is committed to following local regulator requirements wherever we operate,” a spokesperson told CNBC.
This year, Chinese authorities have intensified a crackdown on cryptocurrencies that has targeted bitcoin miners and trading.
But China’s tough stance on cryptocurrencies is not new. Authorities in the world’s second-largest economy have long been worried about the impact of digital coins on financial stability.

Amazon is facing a federal probe after one of its delivery drones downed an internet cable in central Texas last week.
The probe comes as Amazon vies to expand drone deliveries to more pockets of the U.S., more than a decade after it first conceived the aerial distribution program, and faces stiffer competition from Walmart, which has also begun drone deliveries.
The incident occurred on Nov. 18 around 12:45 p.m. Central in Waco, Texas. After dropping off a package, one of Amazon’s MK30 drones was ascending out of a customer’s yard when one of its six propellers got tangled in a nearby internet cable, according to a video of the incident viewed and verified by CNBC.
The video shows the Amazon drone shearing the wire line. The drone’s motor then appeared to shut off and the aircraft landed itself, with its propellers windmilling slightly on the way down, the video shows. The drone appeared to remain in tact beyond some damage to one of its propellers.
The Federal Aviation Administration is investigating the incident, a spokesperson confirmed. The National Transportation Safety Board said the agency is aware of the incident but has not opened a probe into the matter.
Amazon confirmed the incident to CNBC, saying that after clipping the internet cable, the drone performed a “safe contingent landing,” referring to the process that allows its drones to land safely in unexpected conditions.
“There were no injuries or widespread internet service outages. We’ve paid for the cable line’s repair for the customer and have apologized for the inconvenience this caused them,” an Amazon spokesperson told CNBC, noting that the drone had completed its package delivery.
The incident comes after federal investigators last month opened a separate probe into a crash involving two of Amazon’s Prime Air drones in Arizona. The two aircrafts collided with a construction crane in Tolleson, a city west of Phoenix, prompting Amazon to temporarily halt drone deliveries in the area.
For over a decade, Amazon has been working to realize founder Jeff Bezos’ vision of drones whizzing toothpaste, books and other goods to customers’ doorsteps in 30 minutes or less. The company began drone deliveries in 2022 in College Station, Texas, and Lockeford, California.
But progress has been slowed by a mix of regulatory hurdles, missed deadlines and layoffs in 2023 that coincided with broader cost-cutting efforts by Amazon CEO Andy Jassy.
The company has previously said its goal is to deliver 500 million packages by drone per year by the end of the decade.
The hexacopter-shaped MK30, the latest generation of Amazon’s Prime Air drone, is meant to be quieter, smaller and lighter than previous versions.
Amazon says the drones are equipped with a sense-and-avoid system that enables them to “detect and stay away from obstacles in the air and on the ground.” The company recommends that customers maintain “about 10 feet of open space” on their property so drones can complete deliveries
The company began drone deliveries in Waco earlier this month for customers within a certain radius of its same-day delivery site who order eligible items weighing 5 pounds or less. The drone deliveries are supposed to drop packages off in under an hour.
Amazon has brought other locations online in recent months, including Kansas City, Missouri, Pontiac, Michigan, San Antonio, Texas, and Ruskin, Florida. Amazon has also announced plans to expand drone deliveries to Richardson, Texas.
Walmart began offering drone deliveries in 2021, and currently partners with Alphabet’s Wing and venture-backed startup Zipline to make drone deliveries in a number of states, including in Texas.

Uneasy lies the head that wears the crown.
Shares of artificial intelligence czar Nvidia fell 2.6% on Tuesday as signs of unrest continued rippling through its kingdom.
Over the month, Nvidia has been contending with concerns over lofty valuations and an argument from the “The Big Short” investor Michael Burry that companies may be overestimating the lifespan of Nvidia’s chips. That accounting choice inflates profits, he alleged.
The pressure intensified last week in the form of a potential challenger to the crown. Google on Nov. 18 announced the release of its new AI model Gemini 3 — so far so good, given that Nvidia isn’t in the business of designing large language models — powered by its in-house AI chips — uh–oh.
And on Monday stateside, Meta, a potential kingmaker, appeared to signal that it is considering not just leasing Google’s custom AI chips, but also using them for its own data centers. It seemed like Nvidia felt the need to address some of those rumblings.
The chipmaker said on the social media platform X that its technology is more powerful and versatile than other types of AI chips, including the so-called ASIC chips, such as Google’s TPUs. Separately, Nvidia issued a private memo to Wall Street that disputed Burry’s allegations.
Power, whether in politics or semiconductors, requires a delicate balance.
Remaining silent may shroud those in power in a cloak of untouchability, projecting confidence in their authority — but also aloofness. Deigning to address unrest can soothe uncertainty, but also, paradoxically, signal insecurity.
For now, the crown is Nvidia’s to wear — and the weight of it is, too.

And finally…
Lights on in skyscrapers and commercial buildings on the skyline of the City of London, UK, on Tuesday, Nov. 18, 2025. U.K. business chiefs urged Chancellor of the Exchequer Rachel Reeves to ease energy costs and avoid raising the tax burden on corporate Britain as she prepares this year’s budget.
The run-up to this year’s U.K. Autumn Budget has been different from the norm because so many different tax proposals have been floated, flagged, leaked and retracted in the weeks and months leading up to Wednesday’s statement.
It has also made it harder to gauge what we’re actually going to get when Finance Minister Rachel Reeves finally unveils her spending and taxation plans for the year ahead.

Workday shares slid more than 5% in extended trading Tuesday after the finance and human resources software maker issued quarterly margin guidance that came in below Wall Street projections.
Here’s how the company did in comparison with LSEG consensus:
Earnings per share: $2.32 adjusted vs. $2.18 expected
Revenue: $2.43 billion vs. $2.42 billion expected
The company forecast a fourth-quarter adjusted operating margin of at least 28.5% and $2.355 billion in subscription revenue, according to a statement. The StreetAccount consensus was a 28.7% margin and $2.35 billion in subscription revenue.
Workday’s revenue grew about 13% year over year in the quarter, which ended on Oct. 31. Net income of $252 million, or 94 cents per share, was up from $193 million, or 72 cents per share, in the same quarter a year ago.
Subscription revenue in the third quarter totaled $2.24 billion, with an adjusted operating margin of 28.5%. Analysts polled by StreetAccount had anticipated $2.24 billion in subscription revenue and a 28.1% margin.
During the fiscal third quarter, Workday announced artificial intelligence agents for analyzing employee performance testing financial health, and the company revealed plans to buy AI and learning software startup Sana for $1.1 billion. Also, activist investor Elliott Management said it had built a Workday stake worth over $2 billion.
Workday has seen its stock decline this year as pundits discuss the risk of generative AI tools threatening the growth prospects for cloud software incumbents. Company shares have fallen 9% so far in 2025, while the Nasdaq Composite index has gained 19%.
