Bitcoin Rebounds as $500B Quantum Vulnerability Emerges, Nvidia Faces CEO Shake-Up

Bitcoin has recovered from its recent decline as reports emerge that Nvidia’s board is considering replacing CEO Jensen Huang following revelations about two extramarital relationships. At the same time, Glassnode data indicates that approximately 7.12 million BTC, valued at more than $500 billion, have publicly exposed keys that could potentially be compromised by future quantum computing technology.

The developments have brought renewed attention to risks facing two major technology sectors. Bitcoin is confronting questions about the durability of its cryptographic security, while Nvidia faces potential leadership changes that could influence its AI dominance and long-term strategy.

Nvidia shares dropped more than 8% in after-hours trading following reports of discussions about Huang’s possible removal. Directors are reportedly considering an interim leadership appointment while evaluating candidates for a permanent successor.

Bitcoin Rebounds as Quantum Computing Threat Puts $500 Billion in BTC at Risk

Bitcoin recovered after reaching approximately $72,600 on November 10, climbing toward $74,000 before retreating to around $73,700. The bounce offered temporary relief following the recent market downturn. However, new Glassnode findings have highlighted a potential security issue involving more than one-third of Bitcoin’s circulating supply.

According to Glassnode, approximately 35.4% of Bitcoin’s total supply, equivalent to 7.12 million BTC, has publicly exposed keys. At current valuations, these holdings represent more than $500 billion.

The exposure largely originates from address reuse. When Bitcoin is spent from an address, its public key becomes visible on the blockchain. Any remaining funds associated with that address could potentially become vulnerable if quantum computers eventually develop the ability to exploit this information. Glassnode notes that transferring the funds to new addresses can eliminate this particular vulnerability.

The potential threat involves Shor’s algorithm, which could theoretically allow sufficiently advanced quantum computers to calculate private keys using publicly available information. If such computing capabilities become practical, Bitcoin addresses relying on vulnerable cryptographic methods could face serious security challenges.

Developers are already investigating potential solutions. BIP 360 proposes alternative transaction structures designed to limit public-key exposure, while BIP 361 outlines a possible transition away from signature schemes considered vulnerable to quantum attacks.

Nvidia Board Reportedly Discusses Removing Jensen Huang Following Controversies

Nvidia’s leadership has come under increasing scrutiny after Reuters reported that the company’s board was preparing to discuss Huang’s potential removal. The 63-year-old co-founder has spent more than three decades building Nvidia into the world’s leading AI chip supplier. However, revelations involving two extramarital relationships have reportedly triggered internal investigations and raised questions about his position.

One controversy involves businesswoman Alice Huang, whose reported relationship with Jensen Huang has attracted attention from US intelligence officials. She is suspected of potentially helping Nvidia chips reach Chinese companies, raising concerns about possible Chinese intelligence connections and the transfer of restricted technology.

A separate New York Times report identified Kimberly Powell, Nvidia’s vice president of healthcare, in connection with another reported relationship. Powell reportedly worked directly under Huang, adding further corporate governance concerns to the situation.

Huang reportedly acknowledged being unfaithful to his wife in a message to employees and accepted responsibility for his actions. Meanwhile, the board’s reported position has shifted. Although directors had previously supported him, Bloomberg subsequently reported that Nvidia had hired an external firm to evaluate potential CEO replacements.

Nvidia has 11 board members, with all except Huang classified as independent directors. The company’s bylaws reportedly allow the chief executive to be removed through a majority vote.

Chief Financial Officer Colette Kress is reportedly being considered for an interim leadership position, while data-center executive Ian Buck has emerged as a potential long-term successor. The uncertainty comes ahead of Nvidia’s scheduled quarterly earnings announcement on November 17.

Bitcoin Recovery Brings Long-Term Security Risks Into Focus

Bitcoin’s latest rebound has provided some relief to investors following the November 10 sell-off. Buyers entered around the $72,700 region, helping BTC recover toward $74,000. A sustained move above this level could create an opportunity to challenge higher resistance.

However, growing concerns about quantum computing are shifting attention toward Bitcoin’s long-term technological resilience. Developers are examining possible cryptographic upgrades to protect the network against future advances that could undermine existing security mechanisms.

Nvidia faces a different challenge. Huang’s potential departure would represent a significant change for a company whose growth and AI ambitions have been closely associated with its founder. Investors may reconsider Nvidia’s leadership structure and strategic direction if the board moves toward appointing a successor.

For Bitcoin, the potential exposure of more than $500 billion in holdings highlights the importance of preparing for emerging technological threats. The network’s ability to adapt could become an important factor in maintaining long-term investor confidence.

Zcash Struggles to Reclaim $1,000 as Selling Pressure Continues

Zcash remains under pressure after a steep decline pushed the privacy-focused cryptocurrency to its lowest level since September. ZEC is trading near $980, extending its weekly losses beyond 26% as bearish momentum continues to dominate.

The decline has placed the psychologically important $1,000 threshold under pressure. Traders are watching whether buyers can reclaim this level or whether continued selling will drive prices further downward.

Zcash is also approaching its 0.5 Fibonacci retracement level, which could provide a potential support zone for traders anticipating a short-term recovery.

The weakness comes despite Grayscale’s recent commitment of $1 million toward supporting the Zcash ecosystem. However, the funding announcement has not generated enough buying interest to reverse the ongoing decline.

A meaningful recovery could depend partly on Bitcoin stabilizing after its recent losses. Continued weakness across the broader crypto market could make it harder for ZEC to attract fresh capital and establish a sustainable price floor.

Ethereum Tests $2,000 as Selling Pressure Limits Recovery Attempts

Ethereum is facing renewed challenges as its latest recovery attempt loses momentum. After giving back its August gains, ETH has returned to the $1,900–$2,050 range, placing a major technical area under pressure.

The $2,000 level has become a critical point for market participants. Buyers need to defend this threshold to prevent another significant decline, while traders are also monitoring $2,200 as the next important resistance level.

A sustained move above $2,200 could strengthen expectations of a broader recovery. Until then, Ethereum’s upward movements may remain temporary rebounds rather than indicate a confirmed bullish reversal.

Bitcoin ETFs Record Five Straight Days of Outflows as Bull Trap Fears Intensify

Bitcoin’s recovery continues to face resistance as institutional investors withdraw capital from the market. US spot Bitcoin ETFs recorded five consecutive trading sessions of net outflows, losing approximately $1.44 billion between November 5 and November 11.

BTC is trading around $73,500 and has yet to reclaim the $75,000 level. Persistent withdrawals have raised concerns that the latest rebound could develop into another bull trap, potentially exposing investors to further losses.

The negative trend followed Bitcoin’s brief move above $80,000 on November 4. However, the cryptocurrency reversed sharply the following day and has struggled to regain its previous momentum.

ETF data shows that spot Bitcoin investment products recorded $430.2 million in net withdrawals on November 5, followed by another $411.9 million on November 6. Outflows continued on November 9, 10, and 11, extending the withdrawal streak to five sessions.

BlackRock’s iShares Bitcoin Trust (IBIT) accounted for the largest share of the latest selling activity, recording $269.7 million in net outflows on Tuesday.

Continued institutional withdrawals could prevent Bitcoin from establishing a stronger recovery. Until ETF demand improves and BTC moves back above $75,000, concerns about another failed rally are likely to remain elevated.
