AI investment pullback and Zcash vulnerability strike cryptocurrency markets The cryptocurrency market has rapidly declined amid a recent risk-off sentiment, with major assets, led by Bitcoin and Ethereum, posting significant weekly losses. Market participants point to semiconductor giants revising down their AI-related forecasts, which weighed on equities and triggered capital outflows from cryptocurrencies. As a result, Bitcoin dropped to near key support levels, marking its most severe price movement since July 2024.

Researchers identified a theoretical flaw in the “Orchard” shielded pool—designed to ensure anonymity—that could allow for the falsification of supply. The project swiftly deployed an emergency patch. However, due to the protocol’s inherent design, third parties cannot fully verify whether illicit minting actually occurred, amplifying investor anxiety and causing ZEC to plummet sharply in a short time. ([https://t.co/Va84G2Hlol](https://t.co/T1x87P1ktC)) During this sharp decline, massive leveraged liquidations occurred. Reports indicate that billions of dollars in long positions, primarily in Bitcoin and Ethereum, were liquidated within a short period, further deteriorating market liquidity. This chain reaction of position liquidations exacerbated downward price momentum. Institutional investor flows also weighed on the market. Observations include sales by a major asset manager and sustained outflows from spot ETFs, prompting concerns that the market lacks new buyers. Analysts suggest that market participants are increasingly holding back from cryptocurrencies amid high interest rates and a temporary pullback in equity markets driven by AI-themed rallies.

The developer community has begun exploring institutional measures to restore trust, including adopting “turnstile accounting” to enhance transparency in shielded pools and evaluating new pool architectures. While short-term technical fixes are underway, long-term institutional safeguards are now the focus. Meanwhile, the project team has stated that no evidence of actual exploitation has been confirmed to date. The market remains unstable, with liquidity and trust recovery emerging as key focal points going forward. ([https://t.co/pogAHcsLvE](https://t.co/LxYgkFajmk))
