What is the Quantum Computing Threat to Bitcoin Encryption?

Quantum computing represents an emerging technology that could potentially undermine Bitcoin’s encryption protocols, which rely on algorithms like elliptic curve cryptography to secure transactions and wallets. According to Jan van Eck, CEO of investment manager VanEck, this advancement might compromise Bitcoin’s privacy features, prompting the community to evaluate its long-term viability. While the threat is not immediate, proactive measures within the Bitcoin ecosystem are essential to safeguard against future disruptions.

Jan van Eck says quantum computing could threaten Bitcoin’s encryption and privacy, and his firm “will walk away” if it’s “fundamentally broken.”

Bitcoin’s encryption and privacy could be at risk from quantum computing, but it is still a good investment for now, says Jan van Eck, CEO of investment manager VanEck.

How Are Bitcoin Community Members Responding to Privacy Risks?

The Bitcoin community is actively addressing potential vulnerabilities by exploring enhanced privacy solutions, with many original Bitcoin advocates turning their attention to privacy-focused alternatives like Zcash. Zcash employs advanced cryptographic techniques, such as zero-knowledge proofs, to enable fully shielded transactions that conceal sender, receiver, and amount details without sacrificing verifiability. This shift underscores a broader push for robust privacy in cryptocurrencies, especially as regulatory scrutiny intensifies on transparent blockchains like Bitcoin’s.

“There is something else going on within the Bitcoin community that non-crypto people need to know about,” van Eck told CNBC on Saturday. “The Bitcoin community has been asking itself: Is there enough encryption in Bitcoin? Because quantum computing is coming.”

He said that the company believes in Bitcoin (BTC), but it was around before the cryptocurrency launched and “will walk away from Bitcoin if we think the thesis is fundamentally broken.”

VanEck is one of the world’s largest crypto asset managers and has multiple Bitcoin products, including a spot Bitcoin exchange-traded fund in the US that has taken in over $1.2 billion in inflows since launching in early 2024.

Bitcoiners Eye Zcash for Enhanced Privacy

Van Eck said that a lot of Bitcoin “OGs or maxis” have been looking at Zcash (ZEC), a privacy-focused token, in their search for more privacy for their transactions.

In response to these concerns, prominent figures in the cryptocurrency space are weighing in on the timeline and severity of the quantum threat. Cryptographer and cypherpunk Adam Back, a key contributor to Bitcoin’s early development, stated earlier this month that Bitcoin is unlikely to face a meaningful threat from quantum computing for at least two to four decades. This assessment aligns with current expert consensus from institutions like the National Institute of Standards and Technology (NIST), which is actively developing quantum-resistant cryptographic standards. Back’s perspective provides reassurance, emphasizing that Bitcoin’s protocol can evolve through soft forks or upgrades to incorporate post-quantum cryptography before any real danger materializes.

Meanwhile, the surge in interest for privacy coins has been evident in market performance. Zcash has experienced remarkable growth, soaring by over 1,300% in the past three months as investors and users flock to assets that prioritize anonymity amid increasing demands for confidential transactions. This trend reflects a maturing crypto landscape where privacy is no longer an afterthought but a core requirement for widespread adoption. Experts note that while Bitcoin’s pseudonymous nature offers some protection, true privacy coins like Zcash address gaps that quantum advancements could exploit, potentially integrating hybrid solutions in the future.

Bear Market Dynamics and Investment Strategies

The broader market context adds another layer to investor considerations, as Bitcoin navigates what appears to be a pricing-in of bearish cycles. Van Eck highlighted the four-year halving cycle’s influence, noting that every four years over the past decade, Bitcoin has endured significant drawdowns, with 2026 poised for another potentially challenging period. Despite this, he advocates for dollar-cost averaging during bear phases, arguing it mitigates risks compared to chasing peaks in bull markets.

Van Eck concluded that the four-year cycle is being priced in right now, recommending dollar-cost averaging into bear markets rather than chasing bull markets.

Van Eck emphasized that Bitcoin “for sure” merits inclusion in diversified portfolios due to macroeconomic liquidity trends and the tangible realities of its on-chain activity. The halving events, which reduce mining rewards and historically precede price volatility, are well-understood by seasoned investors. For instance, post-2024 halving, Bitcoin reached an all-time high in early October before declining more than 30%, bottoming at just over $82,000 on Friday and recovering to around $88,000 in early trading on Monday. This volatility, while concerning, is viewed by VanEck as a predictable pattern that savvy investors can navigate strategically.

He said Bitcoin “for sure” needs to be included in investor portfolios due to “mainstream global liquidity reasons,” and the “onchain reality.” 

He briefly explained that halving cycle, adding that every four years over the past decade, Bitcoin has had a big negative year, “and in 2026 it’s scheduled to have a big negative year,” and investors have been pre-positioning for this bearish move. 

“Every cycle is different. What’s obvious to everybody is that Bitcoin has gone up less this cycle, and so many people think it will go down less in the correction.”

Bitcoin has lost more than 30% since its early October all-time high, bottoming out at just over $82,000 on Friday before recovering to tap $88,000 in early trading on Monday. 

In parallel, advancements in quantum technology continue to progress, as evidenced by recent announcements from IBM regarding new chips that mark a step toward scalable quantum computers. While these developments are exciting for computing innovation, they heighten the urgency for the crypto sector to prepare. Financial analysts from firms like VanEck stress that Bitcoin’s fundamentals—decentralization, scarcity, and network effects—remain strong, but ongoing vigilance against technological disruptions is crucial. This balanced view encourages investors to maintain exposure while staying educated on evolving risks.
