VanEck Questions Bitcoin Privacy as OKX Relists Zcash, ZEC Jumps Into Top 15

Quantum warnings are prompting some investors to reassess Bitcoin's long-term security.

Overview

  • In a CNBC interview, VanEck CEO Jan van Eck questioned Bitcoin's encryption and privacy, said the firm would exit if the thesis proves broken, and later wrote on X that the bear market reflects halving dynamics, quantum concerns and Zcash's stronger privacy.
  • OKX said on Nov. 23 it will relist Zcash, with ZEC/USDT spot trading set to resume on Nov. 24 at 12:00 UTC, deposits reopened immediately, and withdrawals due two hours after trading starts.
  • Zcash climbed to the 13th-largest crypto asset with a market cap near $9.43 billion, recently trading around $578.35 after a 24-hour gain of about 17% and steep month-to-date and year-to-date increases.
  • Van Eck said some longtime Bitcoin holders are examining Zcash for stronger transaction privacy given Bitcoin’s transparent ledger.
  • Technologists including Vitalik Buterin and Scott Aaronson warned that advances in quantum computing could threaten elliptic-curve cryptography, while Bitcoin advocate Samson Mow publicly rejected claims that maxis are shifting to privacy coins.
