The CEO of VanEck, a firm involved with #BTC and #ZEC , voiced concerns regarding Bitcoin's "adequate encryption" and "adequate privacy." The transparent nature of Bitcoin's blockchain may conflict with the growing demand for transaction privacy. If his argument proves to be fundamentally flawed, we might need to consider alternatives to Bitcoin. While we don't currently see this as necessary, it's crucial to continuously assess both the technology and the cryptocurrency itself. He also pointed out that some long-term Bitcoin investors are exploring Zcash for its superior privacy features.
