Social media personality Supercar Blondie, a London-based Australian whose real name is Alex Hirschi, found her niche posting automotive eyecandy for eager viewers rather accidentally.
“I started out as a journalist, and I just fell into cars through my radio show,” says Hirschi.
For someone who “fell into” cars, they’ve certainly been good to her—the Supercar Blondie network of social channels that includes Supercarblondie.com has 110 million subscribers, including 18.4 million on YouTube and 56 million on Facebook. The content has 2 billion views per month, according to the company.

Hirschi, whose first car was a lowly Mitsubishi Lancer, produces the Supercar Blondie content with her husband, Nik Hirschi, who is Swiss. The radio show was on the Arabian Radio Network in Dubai from 2012 to 2017. Dubai is full of supercars, and Hirschi, then known as “Radio Blondie,” said it was a natural fit to drive some of them—Bentleys, McLarens, Ferraris—for on-air features. The independent Supercar Blondie content creation company was launched in Dubai (where Nik Hirschi worked at Bloomberg, Barclays, and Thomson Reuters) in 2017 and has been growing ever since.
“I just loved supercars, and what started out as a hobby after I was loaned a Bentley Flying Spur to drive around Dubai eventually got more serious,” Alex Hirschi says. “We started filming my encounters with cars and uploading the video to our channel.” These days the couple travels 300 days a year; Penta first caught up with them at the Consumer Electronics Show in Las Vegas .

And now SB Media Group, based in London with 65 employees, Nik as CEO and Alex as the co-founder and on-air talent, is going into the auto auction business. SBX Cars, based in California, launched this week. The inaugural inventory goes beyond cars, and includes an electric Tyde hydrofoil yacht designed by BMW. There’s also a no-reserve Tesla Cybertruck, a one-of-nine Lamborghini Veneno Roadster, and a one-of-three Lamborghini Veneno Coupe. Likely attracting attention will be the first public auctions of the Mercedes-AMG One and the Hyperion XP-1 hydrogen-powered prototype. There were three LaFerrari prototypes, and one will be auctioned by SBX Cars.
A collection of John Player Special Lotus F1 racing cars will also be auctioned, as well as Lotus transporters, and founder Colin Chapman’s personal plane and some vehicles from his garage. Other high-dollar items include a Mercedes 300SL “Gullwing,” a Lamborghini Miura, a BMW 507, and an Aston Martin DB5. The estimated valuation of the auction lots consigned is US$100 million.

The auctions will be online, but there could be some in-person events in the future. “We’re going to be the only digital auction site that focuses on the high end,” Nik Hirschi says. “We will focus on cars that are super-cool, with many that are one-of-a-kind, and we’re going to be attracting collectors from all over the world. Every car will be represented on the site with 200 photographs, taken by our global network.” Video will also be available.
SBX Cars says it will speed up the process for consignors, with just a few weeks until their cars become available on the site. Once up, the vehicles will remain available for one to two weeks. SBX Cars Auction Director Lance Butler, a Bonhams veteran, said in a statement that the auction “introduces our clients to a far easier buying and selling process, all while accessing one of the world’s largest global audiences by way of Supercar Blondie.”

Selloff in bitcoin and other digital tokens hits crypto-treasury companies.
The hottest crypto trade has turned cold. Some investors are saying “told you so,” while others are doubling down.
It was the move to make for much of the year: Sell shares or borrow money, then plough the cash into bitcoin, ether and other cryptocurrencies. Investors bid up shares of these “crypto-treasury” companies, seeing them as a way to turbocharge wagers on the volatile crypto market.
Michael Saylor pioneered the move in 2020 when he transformed a tiny software company, then called MicroStrategy , into a bitcoin whale now known as Strategy. But with bitcoin and ether prices now tumbling, so are shares in Strategy and its copycats. Strategy was worth around $128 billion at its peak in July; it is now worth about $70 billion.
The selloff is hitting big-name investors, including Peter Thiel, the famed venture capitalist who has backed multiple crypto-treasury companies, as well as individuals who followed evangelists into these stocks.
Saylor, for his part, has remained characteristically bullish, taking to social media to declare that bitcoin is on sale. Sceptics have been anticipating the pullback, given that crypto treasuries often trade at a premium to the underlying value of the tokens they hold.
“The whole concept makes no sense to me. You are just paying $2 for a one-dollar bill,” said Brent Donnelly, president of Spectra Markets. “Eventually those premiums will compress.”
When they first appeared, crypto-treasury companies also gave institutional investors who previously couldn’t easily access crypto a way to invest. Crypto exchange-traded funds that became available over the past two years now offer the same solution.
BitMine Immersion Technologies , a big ether-treasury company backed by Thiel and run by veteran Wall Street strategist Tom Lee , is down more than 30% over the past month.
ETHZilla , which transformed itself from a biotech company to an ether treasury and counts Thiel as an investor, is down 23% in a month.
Crypto prices rallied for much of the year, driven by the crypto-friendly Trump administration. The frenzy around crypto treasuries further boosted token prices. But the bullish run abruptly ended on Oct. 10, when President Trump’s surprise tariff announcement against China triggered a selloff.
A record-long government shutdown and uncertainty surrounding Federal Reserve monetary policy also have weighed on prices.
Bitcoin prices have fallen 15% in the past month. Strategy is off 26% over that same period, while Matthew Tuttle’s related ETF—MSTU—which aims for a return that is twice that of Strategy, has fallen 50%.
“Digital asset treasury companies are basically leveraged crypto assets, so when crypto falls, they will fall more,” Tuttle said. “Bitcoin has shown that it’s not going anywhere and that you get rewarded for buying the dips.”
At least one big-name investor is adjusting his portfolio after the tumble of these shares. Jim Chanos , who closed his hedge funds in 2023 but still trades his own money and advises clients, had been shorting Strategy and buying bitcoin, arguing that it made little sense for investors to pay up for Saylor’s company when they can buy bitcoin on their own. On Friday, he told clients it was time to unwind that trade.
Crypto-treasury stocks remain overpriced, he said in an interview on Sunday, partly because their shares retain a higher value than the crypto these companies hold, but the levels are no longer exorbitant. “The thesis has largely played out,” he wrote to clients.
Many of the companies that raised cash to buy cryptocurrencies are unlikely to face short-term crises as long as their crypto holdings retain value. Some have raised so much money that they are still sitting on a lot of cash they can use to buy crypto at lower prices or even acquire rivals.
But companies facing losses will find it challenging to sell new shares to buy more cryptocurrencies, analysts say, potentially putting pressure on crypto prices while raising questions about the business models of these companies.
“A lot of them are stuck,” said Matt Cole, the chief executive officer of Strive, a bitcoin-treasury company. Strive raised money earlier this year to buy bitcoin at an average price more than 10% above its current level.
Strive’s shares have tumbled 28% in the past month. He said Strive is well-positioned to “ride out the volatility” because it recently raised money with preferred shares instead of debt.
Cole Grinde, a 29-year-old investor in Seattle, purchased about $100,000 worth of BitMine at about $45 a share when it started stockpiling ether earlier this year. He has lost about $10,000 on the investment so far.
Nonetheless, Grinde, a beverage-industry salesman, says he’s increasing his stake. He sells BitMine options to help offset losses. He attributes his conviction in the company to the growing popularity of the Ethereum blockchain—the network that issues the ether token—and Lee’s influence.
“I think his network and his pizzazz have helped the stock skyrocket since he took over,” he said of Lee, who spent 15 years at JPMorgan Chase, is a managing partner at Fundstrat Global Advisors and a frequent business-television commentator.
