Bitcoin maximalist and former BitMEX CEO Arthur Hayes has liquidated his Zcash position. The move came right after the public disclosure of a critical vulnerability in Zcash's Orchard Pool, a key privacy feature.
The Orchard Pool Vulnerability
Details of the flaw were made public earlier this week. The vulnerability, which affects the shielded transaction pool introduced in the network's Orchard upgrade, could potentially allow an attacker to link sender and receiver addresses. For a privacy-focused cryptocurrency like Zcash, that's a direct hit to its core value proposition. Developers moved quickly to patch the bug, but Hayes said the disclosure changed his view of the asset's security.
Hayes's Reaction and Selling Pressure
Hayes confirmed he had exited his Zcash holdings entirely. In a statement, he said his decision was driven by the belief that an exploit is still possible despite the patch. He added that he would reconsider his position only if that assumption is proven wrong. The sale adds to selling pressure on Zcash, which has already been struggling with declining user activity and a shrinking market cap relative to other privacy coins.
What Comes Next
The question now is whether Hayes's assumption holds up. If further analysis shows the vulnerability was fully contained, he has indicated he might buy back in. But for the moment, he's out. Other large holders may be watching the same question. For Zcash, the next test will be whether the community and remaining investors trust the fix enough to keep using the shielded pool. The project's developers have not commented on Hayes's specific claims.
