VanEck CEO Flags Quantum Threat to Bitcoin; Firms to Walk Away?
-
VanEck’s CEO warns the firm could exit Bitcoin if quantum risks grow and its core thesis weakens.
-
Bitcoin’s privacy and encryption concerns are pushing ‘OG’ holders to explore Zcash’s shielded model.

Developers face rising pressure as 2026 emerges as a key year for potential post-quantum upgrades.
VanEck’s CEO has put new pressure on Bitcoin’s long-term security, saying the firm would reconsider its position if quantum risks weaken BTC’s core thesis. His comments instantly reignited discussions around Bitcoin’s encryption, transparency, and the growing interest in privacy-focused alternatives.
VanEck CEO Flags Bitcoin’s Encryption and Privacy Issues
In a CNBC interview, Jan van Eck said the Bitcoin community is now focused on two urgent questions: whether Bitcoin’s encryption can stand up to future quantum computers, and whether the network offers enough privacy for users who don’t want their activity exposed.
“We will walk away from Bitcoin if we think the thesis is fundamentally broken,” he said.

“There’s something else going on within the Bitcoin community that non-crypto people need to know about.
And that is: ultimately, VanEck has been around before Bitcoin. We will walk away from Bitcoin if we think the thesis is fundamentally… pic.twitter.com/pCUtuqBVHD

He noted that this debate is no longer niche – longtime Bitcoin holders are openly questioning whether the technology is prepared for the next era of computing.
Van Eck also pointed out that Bitcoin’s transparency is becoming a real concern. Anyone can watch a transaction move from one wallet to another, and that visibility is pushing users to rethink how much information they’re comfortable revealing on-chain.
Zcash Gains Attention as Privacy Conversations Rise
These concerns are sending more “Bitcoin OGs” toward Zcash, a privacy-focused token built with zero-knowledge proofs. Van Eck said many early adopters are studying Zcash’s model as they look for stronger protections than Bitcoin’s transparent design can offer.
Community chatter reflects this shift, with rising interest in shielded transactions and more advanced privacy tools.
Quantum Timeline Raises the Stakes for Institutions
Another part of the discussion centers on quantum risk. Some voices in the community are calling 2026 a realistic target year for quantum-resistant upgrades.
Vitalik Buterin added his own warning recently, saying there’s a notable chance quantum-capable machines could arrive before 2030. Because blockchain upgrades take years, he urged developers to prepare well before the threat becomes real.
Why This Matters for Bitcoin Holders
If Bitcoin doesn’t move toward post-quantum protection, institutions, regulators, and ETF issuers may eventually push for answers. Privacy concerns may also steer more users toward Zcash or other zero-knowledge networks.
What to Watch Next
Attention now turns to Bitcoin’s developers as the community waits to see whether 2026 becomes a real deadline or another warning left unanswered.
