Vaneck ceo's comments questioning bitcoin's fundamental encryption and privacy, along with the possibility of the firm 'walking away,' introduce significant doubt for institutional investors and could erode long-term confidence. the mention of quantum computing risks and zcash as an alternative are serious, forward-looking concerns.
The source is jan van eck, ceo of a major asset manager (vaneck), a highly credible institutional voice. his concerns about encryption and quantum risks are echoed by respected figures like vitalik buterin and quantum researcher scott aaronson, lending significant weight to the claims, even if controversial among bitcoin maximalists.
The ceo's statements directly challenge bitcoin's long-term thesis and explicitly mention a 'bearish for 2026' outlook linked to the halving cycle, quantum risks, and privacy. such fundamental questioning from a major institutional player is likely to induce fud (fear, uncertainty, and doubt) and exert downward pressure on price, especially for long-term holders reassessing their positions.
The concerns raised, particularly regarding quantum computing, encryption, and privacy, are not immediate threats but rather long-term architectural challenges that could impact bitcoin's viability over years. the 'bearish for 2026' outlook for the halving cycle also points to a longer-term timeframe.
Markets Share Share this article Copy link X icon X (Twitter) LinkedIn Facebook Email VanEck CEO Concerned About Bitcoin's Encryption and Privacy, Says Firm Could Walk Away Jan van Eck questioned whether Bitcoin offers enough encryption and privacy, saying some longtime holders are examining Zcash as the market reassesses long-term assumptions. By Siamak Masnavi , AI Boost Nov 23, 2025, 11:18 a.m. Jan van Eck, president and CEO of asset manager VanEck, speaks at Consensus Invest 2018 (CoinDesk) What to know : VanEck CEO Jan van Eck questioned whether Bitcoin has “enough encryption” and “enough privacy” in a CNBC interview. Some longtime Bitcoin holders are looking at Zcash’s stronger privacy features, he said. The remarks drew both support from technologists focused on quantum risks and sharp pushback from some long-term ("OG") Bitcoin advocates. Bitcoin’s long-term design came under renewed scrutiny on Friday after VanEck CEO Jan van Eck questioned whether the network provides sufficient encryption and privacy during an appearance on CNBC’s “Power Lunch” with anchor Brian Sullivan. Van Eck said the issues drawing attention inside the Bitcoin community go beyond short-term market swings. “There’s something else going on within the Bitcoin community that non-crypto people need to know about,” he said.

He added that VanEck evaluates Bitcoin’s staying power the same way it assesses traditional assets. “Ultimately, VanEck has been around before Bitcoin. We will walk away from Bitcoin if we think the thesis is fundamentally broken. We don’t right now, but you always have to look at the underlying technology and the crypto.” He did not define what he meant by “the Bitcoin thesis,” but his comments pointed toward the foundations that support Bitcoin’s long-term viability, including the strength of its cryptography, the network’s readiness for advances in quantum computing and whether its privacy model aligns with user expectations. His remarks centered on whether Bitcoin has “enough encryption” and “enough privacy,” which he said were now central questions for parts of the Bitcoin community. Van Eck also said some longtime Bitcoin holders and self-described maxis have begun examining Zcash, calling it “sort of related to Bitcoin with a lot more privacy.” He argued that Bitcoin’s transparent ledger can clash with rising expectations around transaction confidentiality. “When you move money around on the Bitcoin blockchain, you can see it,” he said. “You can see it move from one wallet to another.” Following the interview, van Eck posted a summary on X, asserting that the current Bitcoin bear market reflects “the onchain reality of the halving cycle (bearish for 2026), quantum-breaking-encryption concerns and the better privacy of Zcash.” He also amplified VanEck portfolio manager Pranav Kanade’s guidance to “dollar cost average into bear markets.” Bitcoin was trading around $84,643 during the CNBC interview. As of 9:15 a.m. UTC on Sunday, Nov. 23, the price was $86,204, up 2.4% in the past 24 hours but down 7.7% year to date and 31.6% below its all-time high of $126,080 on Oct. 6, 2025. Industry Reaction Some voices in the broader crypto and research community echoed van Eck’s concerns. On Nov. 17, during a presentation on the Ethereum roadmap at the Devconnect conference in Argentina, Ethereum co-creator Vitalik Buterin warned that quantum computing could threaten elliptic curve cryptography, stating, “Elliptic curves are going to die.” Separately, in a Nov. 13 blog post , quantum computing researcher Scott Aaronson — the Schlumberger Centennial Chair of Computer Science at the University of Texas at Austin — wrote that “given the current staggering rate of hardware progress,” it is “a live possibility” that a fault-tolerant quantum computer capable of running Shor’s algorithm could be built before the next U.S. presidential election in 2028. Others responded forcefully against van Eck’s remarks. For example, Samson Mow, CEO of JAN3 and one of Bitcoin’s earliest advocates, rejected the idea that Bitcoin maxis are turning to privacy alternatives. In a post on X, he wrote , “You wouldn’t be able to point out a Bitcoin Maxi even if they were standing in front of you. You shouldn’t be speaking on anything Bitcoin whatsoever. You’re a crypto guy, stay in your lane and push the latest shitcoin narrative.” Zcash’s ZEC token has surged as privacy discussions intensify. ZEC is now the 13th-most valuable cryptocurrency with a market capitalization of $9.43 billion and was recently trading at $578.35, up 17.3% in the past 24 hours, 121.3% over the past 30 days and 930% year to date. On Sept. 24, ZEC traded near $55.06.
