Two years ago, Sam Bankman-Fried was a 30-year-old multibillionaire living in a $35 million Bahamas penthouse, partying with his pals while running one of the world’s most valuable crypto companies.
Today, he’s a 32-year-old inmate at the Metropolitan Detention Center in Brooklyn, waiting for a judge to tell him how long he’ll spend behind bars for masterminding “one of the biggest financial frauds in American history,” in the words of U.S. Attorney Damian Williams.
Bankman-Fried, the founder and former CEO of failed crypto exchange FTX, will head on Thursday to a federal court in downtown Manhattan, where U.S. District Judge Lewis Kaplan will deliver his sentencing. Prosecutors have recommended a prison sentence of 40 to 50 years.
It took jurors only about three hours of deliberations in November to find Bankman-Fried guilty of all seven criminal accounts against him. For a high-profile monthlong trial that involved nearly 20 witnesses and hundreds of exhibits, experts said at the time that they’d never seen such a speedy decision. Bankman-Fried plans to appeal his conviction and sentence.
It was a steep and swift fall from grace for Bankman-Fried, who was once hailed as a titan of the industry and had a peak net worth — on paper — of roughly $26 billion.

Bitcoin arbitrage
It started with the Kimchi Swap.
In 2017, as a quant trader at Jane Street, Bankman-Fried noticed something funny when he looked at bitcoin pricing on CoinMarketCap.com. Instead of a uniform price across exchanges, Bankman-Fried would sometimes see a 60% difference in the value of the digital currency. His immediate instinct, he said, was to get in on the arbitrage trade — buying bitcoin on one exchange and selling it back on another, pocketing the difference.
“That’s the lowest hanging fruit,” Bankman-Fried told CNBC in September 2022.
The arbitrage opportunity was especially compelling in South Korea, where the exchange-listed price of bitcoin was significantly higher than in other countries. It was dubbed the Kimchi Premium, a reference to the traditional Korean side dish of salted and fermented cabbage.
After a month of personally dabbling in the market, Bankman-Fried launched Alameda Research, named after the California county that housed his first office. Bankman-Fried told CNBC that the firm sometimes made as much as a million dollars a day trading bitcoin.
Alameda’s success spurred the launch of FTX. In April 2019, Bankman-Fried co-founded FTX.com, an international cryptocurrency exchange that offered customers innovative trading features, a responsive platform and a reliable experience. FTX’s success led to a $2 billion venture fund that seeded other crypto firms.
The FTX logo soon adorned everything from Formula One race cars to a Miami basketball arena. Bankman-Fried talked about one day buying Goldman Sachs, and he became a fixture in Washington as one of the Democratic Party’s top donors.
Then the market turned.
The so-called crypto winter of 2022 wiped out hedge funds and lenders across the crypto universe. Bankman-Fried boasted that he and his enterprise were immune. Behind the scenes, Alameda was borrowing money to invest in failing digital asset firms to keep the industry afloat.
May of 2022 brought the crash of stablecoin Luna, creating a domino effect that sent crypto prices plunging and devastating other lenders.
Alameda had borrowed from lenders including Voyager Digital and BlockFi, which both ended up going bankrupt. Alameda secured its loans with FTT tokens, minted by FTX. Bankman-Fried’s empire controlled the vast majority of the available currency, with only a small amount of FTT actually circulating at any time.
Alameda marked its entire hoard of FTT at the prevailing market price despite it being a virtually illiquid asset. The fund used the same methodology with other coins as well, including Solana and Serum (a token created and promoted by FTX and Alameda), using them to collateralize billions of dollars in loans. Industry insiders called the tokens “Sam coins.”
Virtual bank run
When faced with margin calls due to falling prices, Bankman-Fried turned to FTX customers’ deposits to the tune of billions of dollars by the middle of 2022. According to the firm’s own bankruptcy filings, it possessed almost nothing in the way of record keeping.
On Nov. 2, 2022, crypto trade site CoinDesk publicized details of Alameda’s balance sheet, which showed $14.6 billion in assets. Over $7 billion of those assets were either FTT tokens or Bankman-Fried-backed coins like Solana or Serum. Another $2 billion worth were locked away in equity investments.
Investors began withdrawing their holdings from FTX, creating the threat of a virtual bank run. Alameda and FTX now both faced a liquidity crunch.
On Nov. 6, four days after the CoinDesk article, Binance founder Changpeng Zhao dropped the hammer. Binance was the first outside investor in FTX in 2019. Two years later, FTX bought back its stake with a combination of FTT and other coins, according to Zhao.
Zhao wrote in tweet that, because of “recent revelations that have came [sic] to light, we have decided to liquidate any remaining FTT on our books.” FTX executives scrambled to contain the damage, and Alameda traders managed to fend off outflows for a couple days.
On Nov. 7, Bankman-Fried tried to show confidence, tweeting, “FTX is fine. Assets are fine.” The post was deleted.

Internal discussions were different. Bankman-Fried and other executives admitted to each other that “FTX customer funds were irrevocably lost because Alameda had appropriated them.” By Nov. 8, the client shortfall had grown to $8 billion. Bankman-Fried was courting outside investors for a rescue package but found no suitors.
FTX issued a pause on all customer withdrawals that day. FTT’s price plummeted by over 75%. Out of options, Bankman-Fried turned to Zhao, who announced that he’d signed a “non-binding” letter of intent to acquire FTX.com.
But a day later, on Nov. 9, Binance said it wouldn’t go through with the acquisition, citing reports of “mishandled customer funds” and federal investigations.
FTX filed for bankruptcy on Nov. 11, and Bankman-Fried resigned as CEO of FTX and associated entities. He immediately lost 94% of his personal wealth.
Sullivan & Cromwell, FTX’s longtime attorneys, approached John J. Ray, who oversaw Enron through its bankruptcy, to assume Bankman-Fried’s former position.
On Dec. 12, Bankman-Fried was arrested by Bahamian authorities and extradited to the U.S., where he was taken into custody. Federal prosecutors and regulators accused Bankman-Fried of perpetrating a fraud “from the start,” according to a filing from the SEC.
Bankman-Fried was released on a $250 million bond and was initially living under house arrest with a court-ordered ankle monitor at his parents’ home in Palo Alto, California, on the Stanford University campus. He was soon taken back into custody for alleged witness tampering.
While Bankman-Fried awaited trial, many of his closest friends and confidantes turned into key witnesses for the prosecution, leaving the former crypto billionaire to defend himself. Less than a year after his arrest, the 12-person jury found Bankman-Fried guilty on all criminal charges against him.

The e-bike industry in the West has long been a tale of two territories. North Americans enjoy higher speeds and power limits for their electric bicycles while Europeans are held to much stricter (i.e. slower and lower) speed and power limits. However, things might change based on current discussions on rewriting European e-bike regulations.
New power levels are not totally without precedent, either. The UK briefly considered doubling its own e-bike power limit from 250 watts (approximately 1/3 horsepower) to 500 watts, though the move was ultimately abandoned.
But this time, the call for more power is coming from within the house – i.e., Germany. The Germans are the undisputed leaders and trend setters in the European e-bike market, accounting for around two million sales of e-bikes per year. Home to leading e-bike drive makers like Bosch, the country has yet another advantage when it comes to making – or regulating – waves in the industry.
And while there aren’t any pending law changes, the largest German trade organization ZIV (Zweirad-Industrie-Verband), which is highly influential in achieving such changes, is now discussing what it believes could be pertinent updates to current EU electric bike regulations.
Some of the new regulations involve creating rules maxing out power at levels such as 400% or 600% of the human pedaling input. But a key component of the proposed plan includes changing the present day power limit of e-bikes from 250W of continuous power at the motor to 750W of peak power at the drive wheel.
The difference includes some nuance, since continuous power is often considered more of a nominal figure, meaning nearly every e-bike motor in Europe wears a “250W” or less sticker despite often outputting a higher level of peak power. Even Bosch, which has to walk the tight and narrow as a leader in the European e-bike drive market, shared that its newest models of motors are capable of peak power ratings in the 600W level. That’s still far from the commonly 1,000W to 1,300W peak power seen in US e-bike motors, but offers a nice boost over an actual 250W motor.
Other new regulations up for discussion include proposals to limit fully-loaded cargo e-bike weights to either 250 kg (550 lb) for two-wheelers or 300 kg (660 lb) for e-bikes with more than two wheels. As road.cc explained, ZIV also noted that, “separate framework conditions and parameters must be defined for cargo bikes weighing more than 300 kg (see EN 17860-4:2025) as they differ significantly from EPACs and bicycles in their dynamics, design and operation.” Such heavy-duty cargo e-bikes, which often more closely resemble small delivery vans than large cargo bikes, are becoming more common in the industry and have raised concerns about cargo e-bike bloat, especially in dedicated cycling paths.
It’s too early to say whether European e-bike regulations will actually change, but the fact that key industry voices with the power to influence policy are openly advocating for it suggests that new rules for the European market are a real possibility.

China just laid out a plan to roll out over 100,000 ultra-fast EV charging stations by 2027 – and they’ll all be open to the public.
The National Development and Reform Commission’s (NDRC) joint notice, issued on Monday, asks local authorities to put together construction plans for highway service areas and prioritize the ones that see 40% or more usage during holiday travel rushes.
The NDRC notes that China’s ultra-fast EV charging infrastructure needs upgrading as more 800V EVs hit the road. Those high-voltage platforms can handle super-fast charging in as little as 10 to 30 minutes, but only if the charging hardware is up to speed.
China had 31.4 million EVs on the road at the end of 2024 – nearly 9% of the country’s total vehicle fleet. But charging access is still catching up. As of May 2025, there were 14.4 million charging points, or roughly 1 for every 2.2 EVs.
To keep the grid running smoothly, China wants new chargers to be smart, with dynamic pricing to incentivize off-peak charging and solar and storage to power the charging stations.
To make the business side work, the government is pushing for 10-year leases for charging station operators, and it’s backing the buildout with local government bonds.
The NDRC emphasized that the DC fast chargers built will be open to the public. This is a big deal because a lot of fast chargers in China aren’t. For example, BYD’s new megawatt chargers aren’t open to third-party vehicles.
As of September 2024, China had expanded its charging infrastructure to 11.4 million EV chargers, but only 3.3 million were public.
