It was a week of extremes for bitcoin enthusiasts.
On the plus side, the cryptocurrency rose 12% in the past seven days and the network hash rate hit an all-time high. Hash rate refers to the collective computing power of all miners in the bitcoin network, and the recent high suggests there have never been more miners online, actively securing the network.
At the same time, another key metric this week showed it’s increasingly difficult to make money in the mining business. Investment bank Jefferies wrote in a report that crypto mining was “significantly” less profitable in August. The average daily revenue per exahash, or income per miner, fell by 11.8% from the prior month, Jefferies said.
As bitcoin becomes more of an established, and even mainstream part of the economy, the days of easy money appear to be in the rearview mirror. Institutional capital has poured in since the SEC approved spot bitcoin exchange-traded funds in January, and the bitcoin network is more robust than ever, held together by a vast and decentralized network of miners securing transactions with the help of large banks of machines.
But more people — and their powerful machines — are vying for smaller rewards.
In April, the bitcoin code automatically cut new issuance of the world’s largest cryptocurrency in half, an event that occurs roughly every four years to create scarcity. The halving historically precedes a wave of bankruptcies among bitcoin mining firms, which are suddenly generating much less revenue with the same level of operating costs.
Bitcoin miners are getting hammered by Wall Street.
Marathon Digital is down nearly 30% in 2024, while Riot Platforms has fallen 53%. The price of bitcoin, meanwhile, is up about 44% this year.
Jefferies said North American publicly traded mining firms minted a smaller share of new bitcoin in August compared to July, falling to 19.9% of the total network. They’re still spending on equipment upgrades, meaning efficiency is improving but economics are getting worse.
Marathon CEO Fred Thiel told CNBC that, due to the upgrade cycle, machines are able to hash twice as much as previous models with the same energy use.
“No need to add sites or power, just upgrade systems,” Thiel said.
Riot CEO Jason Les is as bullish as ever on the future of bitcoin despite the challenging economic conditions. He said “bitcoin is the most sound money in the world,” and “low-cost mining is an efficient way to get exposure to it.”
Not all miners are feeling the pinch. Companies like Core Scientific, which emerged from bankruptcy in January, are finding ways to use their massive infrastructure to power artificial intelligence and high-performance computing (HPC).
Last month, Core announced an expanded deal worth $6.7 billion with CoreWeave, an Nvidia-backed startup that’s providing the chipmaker’s graphics processing units (GPUs) for running AI models.
In a note this week, Bernstein singled out Core Scientific as the best-performing publicly traded bitcoin miner, noting that of the miners that have diversified into AI and HPC, Core is the “only one with a material co-location contract with a leading GPU Cloud provider.”
Core has more than doubled in value since its return to the stock market and now has a market cap of close to $3 billion.
“Our facilities were developed to be multi-use for not only just bitcoin mining, but also for the transition that we’re doing right now to high-performance computing,” Core CEO Adam Sullivan told CNBC.
Bernstein added that if Core executes all of its 700 megawatt capacity that it’s allocated to AI and HPC, it would make the company the third-largest data center company listed in the U.S.
“It’s really about the next three years in terms of where the opportunity set truly lies to capture a large portion of the data center market,” Sullivan said. “Every big data center company that exists carved out a niche, just so happens that the niche that bitcoin miners are carving out now are in the largest niche that has ever been found in the data center industry.”

A judge has officially approved a settlement in a case brought by Tesla shareholders against board members who will now have to return stock, cash, and give up on stock options worth a total of nearly $1 billion.
Let me start this article with a quote from Tesla CEO Elon Musk:
Tesla will never settle a case where we’re in the right, and never contest a case where we’re in the wrong.
Today, Chancellor Kathaleen McCormick approved a settlement agreement between Tesla and all its board members from 2017 to 2020 and the Police and Fire Retirement System of the City of Detroit on behalf of Tesla shareholders over what the shareholders believed to be excessive compensation.
The agreement was first reported in July 2023, but it is only now being officially approved and we learn a few more details.
Shareholders believed that members of Tesla’s board were compensating themselves excessively with hundreds of millions of dollars between 2017 and 2020 when the average compensation of a board member of a S&P500 company is just north of $300,000.
Under the settlement, the board members agree to return to Tesla $277 million in cash, $459 million in stock options and to forgo $184 million worth of stock options awarded for 2021-2023.
That adds up to nearly $1 billion.
The board members include Kimbal Musk, Elon’s brother, Brad Buss, Ira Ehrenpreis, Antonio Gracias, Stephen Jurvetson, all close friends of Elon Musk and people who have financial dealings with Musk outside of Tesla, Linda Johnson Rice, Kathleen Wilson-Thompson, Hiromichi Mizuno and Larry Ellison, the co-founder of Oracle Corp and also a close friend of Musk.
As part of the settlement, Tesla or the board does not admit to any wrongdoing.
Musk didn’t take compensation as part of the board, but he is embroiled in a similar case over his own $55 billion CEO compensation package, which was rescinded by the same judge after she found that it wasn’t negotiated or presented to shareholders in good faith.
The board members who received this “excessive compensation” also happened to be the one who “negotiated” Musk’s CEO compensation package.
Despite how cold it may feel outside, Nissan’s electric SUV has likely been through colder. Nissan is proving its Ariya SUV can handle the extreme weather at its unique new test chamber at its tech center near Detroit. With temperatures ranging from -40 to 176 °F, the Ariya is being pushed to see what it’s made of.
Nissan launched the Ariya, its first electric SUV, in the US in late 2022. Over 13,400 Ariya models were sold in the US in its first sales year, with another nearly 20,000 handed over in 2024.
A few weeks ago, Nissan introduced the 2025 Ariya, starting at just $39,770. It has two battery options, 66 or 91 kWh, good for 216 and 289 miles range. That’s for the FWD models.
You can opt for Nissan’s e-4ORCE AWD dual-motor system for “thrilling acceleration” with up to 389 hp and 442 lb-ft of torque. However, with the added power, you sacrifice some range. The AWD Ariya gets up to 272 miles range.
With many parts of the country seeing frigid temperatures, Nissan says its “Ariya is very well equipped” to combat freezing weather.
The electric SUV was already the first vehicle (EV or gas-powered) to drive from the North to the South Pole in 2023. Now, it’s being put through the paces at Nissan’s tech center outside of Detroit.
It’s currently around 23 °F in Detroit, with a low of 11 °F, but Nissan says it’s even colder in its unique new test chamber. The chamber is located at the Nissan Technical Center North America campus, just outside Detroit.
Nissan Ariya handles cold weather tests in new chamber
“Our chambers are capable of temperatures ranging from -40 degrees Fahrenheit to 176 degrees Fahrenheit,” Jeff Tessmer, senior manager of Zero Emission Vehicles at Nissan’s tech center, explained.
Nissan tests the Ariya in a test chamber with “far more extreme” temperatures than the typical driver will see. Tessmer said, “We want to test the worst-case scenario so that our customers will still get the same performance in a wide variety of weather conditions.”
One of the biggest goals is to prove the electric SUV’s battery can maintain charge levels even in extreme weather.
Nissan puts it through “cold soak” tests to ensure performance. During a 24-hour cold soak, the Ariya was parked in -4 °F weather with a 17% battery charge. It also wasn’t plugged in or using its battery heater. After the team returned the next day, the electric SUV still had a 17% charge and started up immediately.
The Ariya is equipped with a battery heater that drivers can turn on ahead of time to ensure optimal performance. On hot days, it includes a liquid-cooled system to regulate battery temperatures.
Drivers can also use the MYNISSAN app to pre-warm the cabin, check the interior temperature, and schedule charging times. Ansu Jammeh, an engineer on Nissan’s Zero Emissions Engineering team, said the best time to use the heating feature is “when the vehicle is plugged in so that it uses power from the grid instead of the vehicle.”

Nissan added a new wireless charging pad across all 2025 Ariya models. The inside features Nissan’s Advanced Drive-Assist setup with dual 12.3″ infotainment and driver display screens formed in a “wave-like” shape.
Other standard features of the 2025 model include wireless Apple CarPlay and Android Auto support, a Head-up display, and a Virtual Personal Assistant. It also includes Nissan’s ProPilot Assist for assisted driving.
Florida’s Rice Creek Solar Energy Center is now online, delivering nearly 75 megawatts (MW) of clean electricity to 12 cities across the state. The solar farm is part of the Florida Municipal Solar Project, one of the largest municipal solar initiatives in the US.
Located in Putnam County, near Palatka, the Rice Creek site is covered with 213,000 solar panels that generate enough power for around 14,000 homes. This marks the third solar site in the Florida Municipal Solar Project, with more on the way.
Twelve utilities are tapping into the clean energy from Rice Creek, including Beaches Energy Services (Jacksonville Beach), Fort Pierce Utilities Authority, Homestead, Keys Energy Services in Key West, Kissimmee Utility Authority, Lake Worth Beach, Mount Dora, New Smyrna Beach Utilities, Newberry, Ocala, Town of Havana, and Winter Park. This is the first solar power project for Havana, New Smyrna Beach, and Newberry.
Jacob Williams, the general manager of the Florida Municipal Power Agency, explained, “By working together, our members and their communities benefit from additional solar-powered energy that’s both cost-effective and carbon-free.”
The FMPA, based in Orlando, coordinates the project, while the 12 municipal utilities – who are also FMPA’s member-owners – purchase the power. Miami-based Origis Energy is the builder, owner, and operator of Rice Creek. According to Origis Energy’s Josh Teigiser, “We are honored to support this FMPA work. Long-term agreements for solar generation, including for Rice Creek Solar, provide a stable rate base contributing to lower and more predictable customers’ bills.”
Construction is already underway on a fourth Florida solar farm, Whistling Duck Solar, in Levy County. The Florida Municipal Solar Project is expected to grow to seven sites in the next few years and will generate a total of around 525 MW of clean energy.
