Crypto Posts Worst Week Since July 2024 as BTC, ETH Near Critical Support

What Happened

Cryptocurrency markets experienced their worst weekly performance since July 2024, with bitcoin declining nearly 15% and ether dropping more than 17% as of June 5, 2026. The selloff coincided with a critical security disclosure regarding zcash and a reported capital rotation away from digital assets.

Privacy coin zcash crashed more than 30% after a security researcher uncovered an exploit capable of minting unlimited tokens. The vulnerability discovery triggered cascading losses across related privacy coins, with monero and dash also declining. Separately, crypto venture capitalist Arthur Hayes disclosed that his firm had sold its entire zcash position, adding to downward pressure on the asset.

Crypto spot trading volume fell to its lowest level since October 2023, signaling reduced market participation during the decline.

Key Details

Bitcoin traded near $61,968, while ether approached the $1,420 level—a critical support zone from April 2025 before the asset's four-month rally to record highs.

The zcash exploit represents a technical threat to the asset's security model. A break below the $1,420 level for ether would open price discovery toward 2022 bear market territory, according to technical analysis cited in market commentary.

The weekly decline marks a reversal from the recent rally that carried both major cryptocurrencies to new all-time highs. The combination of the zcash security issue and what market participants describe as AI capital rotation has intensified selling pressure across the sector.

Why It Matters

The weekly downturn signals weakening momentum in a market that had recovered substantially from 2022 lows. Asset holders face renewed volatility after months of upward price movement.

Ether's approach to critical support levels matters to investors tracking whether the asset can hold above bear market territory. A sustained break below $1,420 would indicate deeper weakness and potentially trigger additional selling.

The zcash security disclosure raises questions about the vetting processes for privacy-focused cryptocurrencies and highlights execution risks for blockchain projects. Hayes's position liquidation suggests institutional participants may be reducing exposure to privacy coins.

Low trading volume during the selloff indicates limited liquidity, which can amplify price moves in either direction.

What Happens Next

Market observers should monitor whether ether holds above the $1,420 support level. A sustained break would signal potential acceleration toward lower price levels.

The zcash vulnerability warrants tracking of the project's remediation timeline and whether the technical fix restores investor confidence. The privacy coin's ability to recover will likely influence sentiment across other privacy-focused digital assets.

Investors should watch for any further large position liquidations from institutional holders and monitor whether spot trading volume stabilizes as selling pressure potentially exhausts.
