Bitcoin’s long-term viability took center stage as VanEck CEO Jan van Eck raised concerns about the cryptocurrency’s encryption and privacy during a recent appearance on CNBC’s “Power Lunch.” In a discussion with anchor Brian Sullivan, van Eck suggested that the issues confronting Bitcoin are not just transient market fluctuations, but deeper foundational questions that may affect its future.
Van Eck indicated that VanEck evaluates Bitcoin similarly to traditional assets, emphasizing the importance of scrutinizing the underlying technology. Although he did not specify what he referred to as the “Bitcoin thesis,” his remarks pointed towards critical elements such as the robustness of Bitcoin’s cryptography, its ability to adapt to advancements in quantum computing, and whether its privacy framework meets user expectations. He highlighted emerging concerns within the Bitcoin community regarding the adequacy of encryption and privacy features, noting that these questions are now at the forefront of discussions among enthusiasts.
Furthermore, van Eck observed that some longtime Bitcoin advocates are exploring alternatives like Zcash, which he described as “sort of related to Bitcoin with a lot more privacy.” He pointed out that the transparent nature of Bitcoin’s blockchain could conflict with user demands for transaction confidentiality, as Bitcoin transactions are traceable from one wallet to another.
Following his interview, van Eck took to social media platform X to summarize his views, asserting that the current bear market of Bitcoin is a reflection of its on-chain realities, alongside concerns over quantum computing and the increasing appeal of Zcash’s privacy features. He also endorsed the advice of Pranav Kanade, a VanEck portfolio manager, encouraging investors to adopt a strategy of “dollar cost averaging” during bear markets.
As of the CNBC broadcast, Bitcoin was valued at approximately $84,643, but it has since climbed to around $86,204—representing a 2.4% increase in a day, though still lower by 7.7% year-to-date and 31.6% below its peak of $126,080 from October 6, 2025.
The reactions from the crypto community have been mixed. Some industry figures share van Eck’s apprehensions, including Ethereum co-creator Vitalik Buterin, who recently highlighted the potential risks that quantum computing poses to algorithms like elliptic curve cryptography. Buterin’s comments were made during a session at the Devconnect conference in Argentina.
Conversely, others in the Bitcoin community have criticized van Eck’s perspective. Samson Mow, CEO of JAN3 and an early Bitcoin proponent, refuted the assertion that Bitcoin maximalists are moving towards privacy-centric alternatives. He challenged van Eck’s authority on Bitcoin matters, suggesting a disconnect between his views and the community’s sentiments.
Amid these discussions, Zcash’s ZEC token has gained prominence, surging in value as conversations around privacy intensify. Currently, ZEC ranks as the 13th most valuable cryptocurrency, with a market cap of $9.43 billion and trading at $578.35—marking a significant increase of 17.3% in just 24 hours and 930% year-to-date.
Van Eck’s insights, in conjunction with the ongoing debates about encryption, privacy, and the readiness of technologies against quantum threats, indicate that discussions concerning Bitcoin’s long-term framework are becoming increasingly pressing as the industry approaches critical milestones, particularly the anticipated halving in 2026. Traders and observers are likely to reassess Bitcoin’s role and relevance as these fundamental questions continue to evolve.
