Quantum risk could threaten about 6.9 million BTC around 2030

Post-quantum security startup Project Eleven released a report stating that the “Q-Day” when quantum computers could break modern cryptography may arrive as early as 2030, and it believes the probability of related breakthroughs before 2033 is “over 50%”. Project Eleven estimates that under certain conditions about 6.9 million BTC could face quantum risk. The report says the industry has already begun researching quantum‑resistant migration solutions, including proving wallet ownership via timestamps and setting multi‑year migration windows to move assets to quantum‑resistant addresses; tech companies such as Google are also advancing quantum‑resistant cryptography migration plans, targeting 2029.

Bitcoin rallies often pull SOL and ETH up, but then all three experience stronger pullbacks.

Are you currently DCA into any other crypto currencies or are you Bitcoin only?

Curious on some of yalls strategies when the crypto market is this low.

Obviously when Bitcoin runs, $Sol , $ETH might run harder 🤷🏻

However they all fall much harder when the run is over 😂

Genius investor Leopold built a $5.5 billion portfolio using AI predictions, which includes Bitcoin mining companies.

Meet the 22 year old guy with no investing experience who got fired from OpenAI, wrote 165 pages predicting the future, and used it to build a $5.5 BILLION portfolio. His previous employer was Sam Bankman-Fried.

Leopold Aschenbrenner was born in Germany around 2001. Both parents were doctors. He enrolled at Columbia University at 15 and graduated as valedictorian at 19. Economist Tyler Cowen called him a prodigy.

He co-founded Columbia’s Effective Altruism chapter. That network led him to the FTX Future Fund, a philanthropic initiative funded by Sam Bankman-Fried’s cryptocurrency exchange. He resigned before FTX collapsed. There is no evidence he knew the money was stolen.

In 2023, he joined OpenAI’s Superalignment team, working under Ilya Sutskever on the problem of controlling AI systems smarter than humans. After a hacker breached OpenAI’s internal messaging system, Aschenbrenner wrote a memo to the board arguing the company’s security was insufficient to prevent theft of model weights by China.

He received a warning from human resources. In April 2024, OpenAI fired him. He said he was told explicitly that the security memo was the real reason.

One month later, the Superalignment team was dissolved. Sutskever left.
Two months after being fired, Aschenbrenner published “Situational Awareness: The Decade Ahead.” 165 pages. It predicted AGI by 2027. Ivanka Trump praised it publicly. The University of Rochester made it required reading.

“Everyone is now talking about AI,” he wrote, “but few have the faintest glimmer of what is about to hit them.”
In September 2024, he launched a hedge fund named after the essay. He reportedly put in nearly all of his personal net worth. Patrick and John Collison of Stripe backed it. So did former GitHub CEO Nat Friedman. Investors agreed to lock up their capital for years.

The thesis was one sentence. AI labs need power, compute, storage, and bandwidth. Nobody was buying the companies that supplied them.

He bought Bloom Energy. Fuel cells for data centres. Lumentum. Optical components that move data between chips. Call options on CoreWeave, a GPU cloud company most investors had never heard of. Core Scientific, a Bitcoin miner pivoting to AI hosting. IREN. Riot Platforms. Hut 8. 20.2 MILLION call options on Intel, a chipmaker Wall Street had written off.

Top 10 positions accounted for 86% of the portfolio. No venture capital. All public markets.

In the first half of 2025, the fund returned 47% after fees. The S&P 500 returned 6%.

By December 2025, the fund’s 13F filing disclosed $5.52 BILLION in U.S. equity and options positions across 29 holdings. Actual assets under management were estimated at $1.5 BILLION. The rest was leverage. Options-heavy, concentrated, thesis-dependent leverage on a single prediction.

He is engaged to Avital Balwit, the chief of staff to the CEO of Anthropic, OpenAI’s largest competitor. In 2024 she wrote that the next five years might be the last years she works. Her fiance built a fund on the same belief.

The career so far: valedictorian at 19, a job at a charity funded with stolen money, a safety team that no longer exists, a firing, a 165-page prediction, and $5.5 BILLION in leveraged bets that it all comes true by 2027. He has been right about everything so far except the places he chose to work.

About Bitcoin

Bitcoin (BTC) is a digital asset and a payment system invented by Satoshi Nakamoto who published a related paper in 2008 and released it as open-source software in 2009. The system featured as peer-to-peer; users can transact directly without an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain. The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value by now.
