Zcash (ZEC) crisis: why the market turned away from the leading privacy coin
In May 2026, after a strong rally that occurred despite a broader cryptocurrency market decline, the price of the leading privacy coin Zcash (ZEC) approached its November 2025 highs, reaching $670. This surge was driven by the sudden popularity of privacy-focused cryptocurrencies amid increasing regulation of the digital asset market.
However, in June, the price of Zcash (ZEC) suddenly collapsed by nearly 50%, falling to $370. On some exchanges, the price of Zcash (ZEC) even dropped below the $300 mark.
Amid the decline, Zcash (ZEC) lost its position in the overall cryptocurrency market capitalization rankings, which fell to $7.8 billion as of June 2026. By this metric, Zcash (ZEC) dropped to 12th place on CoinMarketCap, falling behind Hyperliquid (HYPE), Dogecoin (DOGE), and UNUS SED LEO (LEO).
Zcash (ZEC) falls after an overheated rally
In November 2025, the prices of many cryptocurrencies, including Zcash (ZEC), increased significantly. In just two months, the value of Zcash (ZEC) surged approximately fifteenfold, from $50 to $750.
Experts noted that the price of Zcash (ZEC) continued rising for several weeks even after entering overbought* territory, making the rally one of the longest in the history of the privacy cryptocurrency.
* Overbought refers to a situation where an asset's price rises too quickly and too sharply, potentially making it overvalued. This usually increases the likelihood of a correction or a sharp price decline.
According to analysts, such rapid growth made a significant correction in Zcash (ZEC) inevitable. That is exactly what happened: by December 2025, the value of Zcash (ZEC) had fallen by more than half, nearly reaching $300.
In 2026, the situation is repeating itself. The price of Zcash (ZEC) is declining after an almost uninterrupted three-month rally, during which the privacy cryptocurrency more than tripled in value, rising from $197 to $670.
This time, economic and political instability also had little impact on Zcash (ZEC), unlike many other cryptocurrencies. In early June, the total cryptocurrency market capitalization declined by approximately 12%, from $2.5 trillion to $2.2 trillion. Following the decline in Bitcoin, the leading cryptocurrency, the prices of altcoins (alternative cryptocurrencies), including Zcash (ZEC), also began to fall.
Zcash (ZEC) price drops following the discovery of a critical vulnerability
Renowned security researcher Taylor Hornby discovered a critical vulnerability in the Zcash protocol related to Zcash Orchard transactions. The vulnerability allows attackers to create an unlimited number of counterfeit coins. Investor concerns were further amplified by the fact that the vulnerability had existed within the Orchard protocol for more than four years. Immediately after the publication of the research findings, the price of Zcash (ZEC) fell by more than 30%, dropping to nearly $400.
The study notes that due to the confidential nature of the Zcash protocol, it is difficult to determine whether the vulnerability had ever been exploited by malicious actors. Although developers fixed the exploit in early June, the price of Zcash (ZEC) continued to decline. In less than a week, the value of the privacy cryptocurrency dropped by nearly 12%, from $534 to $470.
In addition, pressure on the price of Zcash (ZEC) intensified after it became known that BitMEX co-founder Arthur Hayes had sold his ZEC holdings. On social media, Arthur Hayes stated that he was unwilling to tolerate a vulnerability in the Zcash blockchain. Following his comments, other investors followed suit, contributing to further declines in the price of Zcash (ZEC).
For the market, this episode proved particularly significant because as recently as spring 2026, Arthur Hayes had publicly described Zcash (ZEC) as one of the most promising cryptocurrencies in the privacy asset sector. Such a dramatic change in stance from one of the industry's most influential figures was interpreted by investors as an additional signal to reduce their exposure to the asset.
Zcash (ZEC) had problems long before the vulnerability was discovered
Despite its strong growth in 2025–2026, Zcash (ZEC) has been facing persistent pressure from regulated cryptocurrency platforms for several years. The main reason is Zcash's status as a privacy coin — a cryptocurrency that enables protected transactions in which the sender, recipient, or transaction amount can be concealed.
For users, this is an advantage because it enhances financial privacy. However, for centralized exchanges, such assets create additional risks related to AML compliance, regulatory requirements, and monitoring the origin of funds. As a result, some platforms have restricted or discontinued support for Zcash (ZEC) and other privacy-focused cryptocurrencies over the years.
For example, as early as 2019, Coinbase UK discontinued support for Zcash (ZEC) for users in the United Kingdom. In the same year, the South Korean exchange Upbit announced the delisting of several privacy coins, including Zcash (ZEC), amid stricter anti-money laundering requirements. Later, regulatory pressure on privacy cryptocurrencies increased in Europe as well. In 2023, Binance announced restrictions on several privacy-focused cryptocurrencies, including Zcash (ZEC), in certain European countries.
Such decisions do not always result in a complete global delisting of a coin. However, they gradually reduce users' access to the asset through regulated platforms. For Zcash (ZEC), this creates a long-term challenge: the fewer major exchanges support the coin, the less accessible it becomes to mainstream investors and the greater the risk of declining liquidity.
For this reason, the Orchard vulnerability was not the sole cause of Zcash's decline but rather a trigger that amplified concerns already present in the market.
